CONCLUSION...679

The Constitution provides that "Representatives shall be apportioned among the several States according to their respective numbers, counting the whole number of persons in each State." U.S. Const. amend. XIV, § 2. To that end, it mandates that an "actual Enumeration" be conducted "every ... ten Years, in such Manner as [Congress] shall by Law direct," an effort commonly known as the census (or, more precisely, the decennial census). Id. art. I, § 2, cl. 3. By its terms, therefore, the Constitution mandates that every ten years the federal government endeavor to count every single person residing in the United States, whether citizen or noncitizen, whether living here with legal status or without. The population count derived from that effort is used not only to apportion Representatives among the states, but also to draw political districts and allocate power within them. And it is used to allocate hundreds of billions of dollars in federal, state, and local funds. Given the stakes, the interest in an accurate count is immense. Even small deviations from an *515accurate count can have major implications for states, localities, and the people who live in them - indeed, for the country as a whole.

Since its inception in 1790, the decennial census also has been used for another purpose: to collect demographic data about the population of the United States, including information about respondents' race, sex, and age, and whether they own or rent their homes. Most relevant here, the government collected data about people's citizenship status from all households in the country in every census between 1820 and 1950 (with the exception of 1840). In 1960, however, the government stopped asking a citizenship question of every respondent, and for decades thereafter the official position of the Census Bureau was that reintroducing such a question was inadvisable because it would depress the count for already "hard-to-count" groups - particularly noncitizens and Hispanics - whose members would be less likely to participate in the census for fear that the data could be used against them or their loved ones. Every Secretary of Commerce (to whom Congress has long delegated significant authority over the census) adhered to that position - until early last year. On March 26, 2018, Secretary of Commerce Wilbur L. Ross, Jr. announced that he was reinstating the citizenship question on the 2020 census questionnaire, purportedly in response to a request from the Department of Justice ("DOJ") for better citizenship data to assist in its enforcement of Section 2 of the Voting Rights Act of 1965 ("VRA"). See 52 U.S.C. § 10301. He did so over the strenuous objections of the Census Bureau itself, which warned that adding a citizenship question would harm the quality of census data and increase costs significantly and that it would do so for no good reason because there was an alternative way to satisfy DOJ's purported needs that would not cause those harms.

The question in these consolidated cases is whether Secretary Ross's decision to reinstate the citizenship question, and the process leading to that decision, violated provisions of statutory or constitutional law. Two sets of Plaintiffs - one, a coalition of eighteen states and the District of Columbia, fifteen cities and counties, and the United States Conference of Mayors (the "Governmental Plaintiffs"), and the other, a coalition of non-governmental organizations (the "NGO Plaintiffs") - challenge the decision on two principal grounds. First, they contend that the decision violated the Administrative Procedure Act ("APA"), which, among other things, prohibits federal agencies from acting in a manner that is arbitrary and capricious or not in accordance with law. Second, they allege that the decision violated the Due Process Clause of the Fifth Amendment because it was motivated in part by invidious discrimination against immigrant communities of color. Defendants - the United States Department of Commerce; Secretary Ross (the "Secretary"); the Bureau of the Census (the "Census Bureau"); and the Director of the Census, Dr. Steven Dillingham1 - have tried mightily to avoid a ruling on the merits of these claims. They asserted a slew of unsuccessful jurisdictional arguments, raised multiple challenges to this Court's decisions authorizing discovery beyond the administrative record collected and filed in this litigation (one of which is still pending before the United States Supreme *516Court), and tried no fewer than fourteen times to halt the proceedings altogether. Between November 5 and 27, 2018, however, this Court held - and completed - an eight-day bench trial to resolve Plaintiffs' claims, taking direct testimony by affidavit from many witnesses and orally from others.

This Opinion contains the Court's findings of fact and conclusions of law following that trial. Broadly speaking, the Court reaches three legal conclusions. First , the Court holds that most, if not all, of Plaintiffs have standing to bring their claims. Specifically, they have proved by a preponderance of the evidence that they will be harmed in various ways as a result of the addition of a citizenship question on the census and that a favorable ruling here will redress those harms. Defendants' own documents and expert witness confirm that adding a citizenship question to the census will result in a significant reduction in self-response rates among noncitizen and Hispanic households. And expert testimony, based in large part on the Census Bureau's own analyses of past censuses, indicates that the Census Bureau's "Non-Response Follow Up" procedures, extensive though they will be, are unlikely to remedy that reduction in self-response rates, which means that hundreds of thousands - if not millions - of people will go uncounted in the census if the citizenship question is included. The result will not only be a decrease in the quality of census data - something Defendants concede - but likely also a net differential undercount (that is, an undercount of certain sectors of the population, including people who live in households containing noncitizens and Hispanics, relative to others). That undercount, in turn, will translate into a loss of political power and funds, among other harms, for various Plaintiffs. In light of these and other factual findings, the Court holds that most, if not all, Plaintiffs have standing to bring their claims.

Second , the Court concludes on the merits that Secretary Ross violated the APA in multiple independent ways. Most blatantly, Secretary Ross ignored, and violated, a statute that requires him, in circumstances like those here, to collect data through the acquisition and use of "administrative records" instead of through "direct inquiries" on a survey such as the census. Additionally, Secretary Ross's decision to add a citizenship question was "arbitrary and capricious" on its own terms: He failed to consider several important aspects of the problem; alternately ignored, cherry-picked, or badly misconstrued the evidence in the record before him; acted irrationally both in light of that evidence and his own stated decisional criteria; and failed to justify significant departures from past policies and practices - a veritable smorgasbord of classic, clear-cut APA violations. On top of that, Secretary Ross acted without observing procedures required by law, including a statute requiring that he notify Congress of the subjects planned for any census at least three years in advance. And finally, the evidence establishes that Secretary Ross's stated rationale, to promote VRA enforcement, was pretextual - in other words, that he announced his decision in a manner that concealed its true basis rather than explaining it, as the APA required him to do. Notably, the Court reaches all of those conclusions based exclusively on the materials in the official "Administrative Record" - that is, the record of materials collected and submitted by Defendants that Secretary Ross allegedly considered, directly or indirectly, prior to making his decision. Looking beyond the Administrative Record merely confirms the Court's conclusions and illustrates how egregious the APA violations were.

*517Third , on the merits of the constitutional claim, the Court concludes that Plaintiffs did not carry their burden of proving that Secretary Ross was motivated by invidious discrimination and thus that he violated the equal protection component of the Due Process Clause. In particular, although the Court finds that Secretary Ross's decision was pretextual, it is unable to find, on the record before it, that the decision was a pretext for impermissible discrimination. To be fair to Plaintiffs, it is impossible to know if they could have carried their burden to prove such discriminatory intent had they been allowed to depose Secretary Ross, as the Court had authorized last September. As defense counsel more or less conceded during closing arguments, a deposition of Secretary Ross would have been the best evidence of the question at the heart of the due process inquiry - namely, the true nature of Secretary Ross's intent in reinstating the citizenship question. But this Court's order authorizing such a deposition was stayed by the Supreme Court pending its further review, see In re Dep't of Commerce , --- U.S. ----, 139 S.Ct. 566, 202 L.Ed.2d 400, 2018 WL 5458822 (Nov. 16, 2018) ; In re Dep't of Commerce , --- U.S. ----, 139 S.Ct. 16, 202 L.Ed.2d 306 (2018) (mem.), and Plaintiffs made the understandable decision to proceed with trial despite that stay (because, with the clock ticking on census preparations, waiting for a final ruling from the Supreme Court could have cost Plaintiffs a meaningful chance to obtain any relief). Be that as it may, it was - and remains - Plaintiffs' burden to prove discriminatory intent, and the evidence in the existing record does not support a conclusion that they carried that burden.

The Court's Opinion is, to put it mildly, long. But that is for good reasons. For one thing, the Court has taken care to thoroughly examine every issue because the integrity of the census is a matter of national importance. As noted, the population count has massive and lasting consequences. And it occurs only once a decade, with no possibility of a do-over if it turns out to be flawed. See Departments of Commerce, Justice, and State, The Judiciary, and Related Agencies Appropriations Act, 1998, § 209(a)(8), Pub. L. No. 105-119, 111 Stat. 2440, 2480-81 (1997) ("1998 Appropriations Act") ("Congress finds that ... the decennial enumeration of the population is a complex and vast undertaking, and if such enumeration is conducted in a manner that does not comply with the requirements of the Constitution or laws of the United States, it would be impracticable for the States to obtain, and the courts of the United States to provide, meaningful relief after such enumeration has been conducted."). For another, time is of the essence because the Census Bureau needs to finalize the 2020 questionnaire by June of this year. See Docket No. 540, at 3; see also Brief for Petitioners at 45, Department of Commerce v. U.S. Dist. Ct. for S.D.N.Y. (Dec. 17, 2018) (No. 18-557), 2018 WL 6650094, at *45 (noting "the need to finalize the census questionnaire by mid-2019").2 With time so short and the likelihood that one or both sides will seek appellate relief so high, it is critical to make a comprehensive record in order to facilitate higher court review and to minimize any potential need for a remand. That means reaching most, if not all, issues raised by the parties - even if, in other circumstances, it would be unnecessary or even inadvisable. See, e.g., Ashwander v. TVA , 297 U.S. 288, 347, 56 S.Ct. 466, 80 L.Ed. 688 (1936) (Brandeis, J., concurring) ("The Court will not pass upon a constitutional question although properly presented *518by the record, if there is also present some other ground upon which the case may be disposed of."). And in light of Defendants' strenuous objections to consideration of any extra-record discovery - objections they are already pressing before the Supreme Court - it also means spelling out which facts are drawn exclusively from the Administrative Record rather than from other evidence, and which conclusions of law are based solely on the Administrative Record rather than on other evidence.3

In short (or not, as the case may be), the Court concludes that Secretary Ross's decision to add the citizenship question to the 2020 census questionnaire, while not inconsistent with the Constitution, violated the APA in several respects. Those violations are no mere trifles. The fair and orderly administration of the census is one of the Secretary of Commerce's most important duties, as it is critical that the public have "confidence in the integrity of the process." Franklin v. Massachusetts , 505 U.S. 788, 818, 112 S.Ct. 2767, 120 L.Ed.2d 636 (1992) (Stevens, J., concurring in part and concurring in the judgment). And although some may deride its requirements as "red tape," the APA exists to protect core constitutional and democratic values: It ensures that agencies exercise only the authority that Congress has given them, that they exercise that authority reasonably, and that they follow applicable procedures - in short, it ensures that agencies remain accountable to the public they serve. That is not to say - and the APA does not say - that an agency cannot adopt new policies or otherwise change course. But the APA does require that before an agency does so, it must consider all important aspects of a problem; study the relevant evidence and arrive at a decision rationally supported by that evidence; comply with all applicable procedures and substantive laws; and articulate the facts and reasons - the real reasons - for that decision. The Administrative Record in these cases makes plain that Secretary Ross's decision fell short on all these fronts. In arriving at his decision as he did, Secretary Ross violated the law. And in doing so with respect to the census - "one of the most critical constitutional functions our Federal Government performs," 1998 Appropriations Act, § 209(a)(5), 111 Stat. at 2480-81, and a "mainstay of our democracy," Franklin , 505 U.S. at 818, 112 S.Ct. 2767 (Stevens, J., concurring) - Secretary Ross violated the public trust.

BACKGROUND

The Court begins with relevant background concerning the history and purpose of the census, the Secretary's authority over the census, and the history of the citizenship question on the census. The relevant background is largely undisputed (for example, as reflected in stipulations of the parties) or drawn from materials of which the Court can take judicial notice. See, e.g. , Fed. R. Evid. 201(b)-(c) ; Effie Film, LLC v. Pomerance , 909 F.Supp.2d 273, 298-303 (S.D.N.Y. 2012) (noting that a court may take notice of undisputed historical facts). To the extent that the Court cites trial testimony or exhibits in what follows, it is only by way of background and does not form a basis for any of the conclusions of law later in this Opinion.4

*519A. History and Purposes of the Census

Article I of the Constitution requires Congress to carry out an "actual Enumeration" every ten years, "in such Manner as [Congress] shall by Law direct." U.S. Const. art. I, § 2, cl. 3. The original and fundamental purpose of this "Enumeration," known as the decennial census, was to apportion congressional representatives (and, where necessary, direct taxes) among the states "according to their respective Numbers." Id. For the first eighty years of the country's history, the states' "respective Numbers" were calculated according to a formula mandated by the same constitutional provision's infamous Three-Fifths Clause, which reformulated the "actual Enumeration" established by the census by "adding to the whole Number of free Persons ..., and excluding Indians not taxed, three fifths of all other Persons" - "all other Persons" being the people then held as slaves. Id. (amended 1868). After the Civil War, that provision was superseded by the Fourteenth Amendment, which provides that "Representatives shall be apportioned among the several States according to their respective numbers, counting the whole number of persons in each State, excluding Indians not taxed." U.S. Const. amend. XIV, § 2 (emphasis added). The result is that the Constitution "requires the federal government to conduct a Decennial Census counting the total number of 'persons' - with no reference to citizenship status - residing in each state." Docket No. 480-1 ("Joint Stips."), ¶ 1.

Significantly, although the "initial constitutional purpose" of the census was to "provide a basis for apportioning representatives among the states in the Congress," it has long "fulfill[ed] many important and valuable functions for the benefit of the country." Baldrige v. Shapiro , 455 U.S. 345, 353, 102 S.Ct. 1103, 71 L.Ed.2d 199 (1982). In particular, it "now serves as a linchpin of the federal statistical system by collecting data on the characteristics of individuals, households, and housing units throughout the country." Department of Commerce v. United States House of Representatives , 525 U.S. 316, 341, 119 S.Ct. 765, 142 L.Ed.2d 797 (1999) (internal quotation marks omitted). See generally U.S. CENSUS BUREAU , MEASURING AMERICA: THE DECENNIAL CENSUSES FROM 1790 TO 2000 ("MEASURING AMERICA ") (2002), http://www2.census.gov/library/publications/2002/dec/pol_02-ma.pdf. "Today, policy makers at all levels of government, as well as private businesses, households, researchers, and nonprofit organizations, rely on an accurate census in myriad ways that range far beyond the single fact of how many people live in each state." COUNCIL OF ECONOMIC ADVISERS , THE USE OF CENSUS DATA: AN ANALYTICAL REVIEW (2000), https://clintonwhitehouse4.archives.gov/media/pdf/censusreview.pdf. Among other things, the data are used "for such varied purposes as computing federal grant-in-aid benefits, drafting of legislation, urban and regional *520planning, business planning, and academic and social studies." Baldrige , 455 U.S. at 353 n.9, 102 S.Ct. 1103.

Since 1790, the government has conducted the required "actual Enumeration" through questions - initially asked in person by U.S. Marshals and "specially appointed agents" and later by means of written questionnaire - about both the number and demographic backgrounds of those living in each American household. See MEASURING AMERICA 125-40. Congress provided for each of the first twelve censuses on an ad hoc basis; then, in 1902, Congress established the "Census Office" that it had organized for the twelfth census as a permanent office within the Department of the Interior, to be supervised by a "Director of the Census" appointed by the President and confirmed by the Senate. See Act of Mar. 6, 1902 §§ 1-3, Pub. L. No. 57-27, 32 Stat. 51, 51. Shortly thereafter, Congress moved the Census Office into the newly created Department of Commerce and Labor. See Act of Feb. 14, 1903 § 4, Pub. L. No. 57-87, 32 Stat. 825, 826-27. Ten years later, various parts of that combined department were transferred into the newly fashioned Department of Labor, and the Census Office was left behind at the slimmed-down (and renamed) Department of Commerce. See Act of Mar. 4, 1913 §§ 1, 3, Pub. L. No. 62-426, 37 Stat. 736, 736-37.5 (Today the "Census Office" is known as the "Bureau of the Census," or the "Census Bureau.") In 1954, Congress enacted the various census-related statutes codified in Title 13 into positive law, see Act of Aug. 31, 1954, Pub. L. No. 83-740, 68 Stat. 1012, and has enacted all subsequent revisions to the census statutes as amendments to Title 13, which, as a result, is known colloquially as the "Census Act."

The modern decennial census is administered exclusively through a "short-form" questionnaire - a short questionnaire containing only a handful of questions. This is a relatively recent phenomenon. Beginning in 1960, and until 2000, each census also included a "long-form" questionnaire, which contained many additional questions but was sent to only a sample fraction of the population. See MEASURING AMERICA 72. In 1960, twenty-five percent of households received the "long-form" questionnaire, while the remainder received the "short-form." Id. In the 1970 and subsequent censuses, approximately one-sixth of all households received the "long-form" questionnaire. See Joint Stips. ¶ 31. During that time, none of the short-form questionnaires included a question about citizenship or birthplace, although the long-form questionnaires each did. See Joint Stips. ¶¶ 30, 35. After the 2000 census, the Census Bureau introduced a new survey instrument, the American Community Survey ("ACS"). Joint Stips. ¶ 37. Unlike the decennial census questionnaires, the ACS is conducted annually and not used to enumerate the population for apportionment purposes. It is distributed to about 3.5 million households (approximately two percent of households in the country) each year, for the sole purpose of collecting demographic data about the population. Since its inception, the ACS has included a question on citizenship. Joint Stips. ¶¶ 38-41. With the advent of the ACS, the Census Bureau phased out the "long-form" decennial census questionnaire. Joint Stips. ¶ 37; see JENNIFER D. WILLIAMS , THE 2010 DECENNIAL CENSUS: BACKGROUND AND ISSUES 3 (2011), https://www.census.gov/history/pdf/2010-background-crs.pdf. Thus, *521the 2010 decennial census included only a single "short-form" questionnaire, distributed primarily by mail. Id. So too, the 2020 census will be conducted with a single short-form questionnaire, which, for the first time, many respondents will complete online. See Tr. 1091.

The modern decennial census begins with a Master Address File ("MAF"), a database containing every known housing unit in the country. See 83 Fed. Reg. 26643, 26644 (June 8, 2018). Every household is then given the opportunity to self-respond to the census questionnaire. Joint Stips. ¶ 7. A majority of households self-respond to that questionnaire. To attempt to count the households that do not self-respond, the Census Bureau uses a set of procedures known as "Non-Response Follow-Up" or "NRFU." Joint Stips. ¶ 8. The first step in NRFU is an in-person visit from a census enumerator. Assuming that a household is listed in the MAF - a precondition for any NRFU efforts - a NRFU enumerator will visit any nonresponding household in person and, if possible, conduct the census survey face-to-face. In the 2020 census, if the NRFU enumerator's first visit is unsuccessful, but the Census Bureau believes the housing unit to be occupied, the Census Bureau will then refer to "administrative records" - data collected from other federal or state entities - to enumerate that household, assuming administrative records of sufficient quality exist. Joint Stips. ¶¶ 9-10; 83 Fed. Reg. at 26649. If the household cannot be enumerated with high-quality administrative records, a NRFU enumerator will return to the household for at least two more in-person attempts. Joint Stips. ¶¶ 10-11. After three unsuccessful attempts to contact a member of the household in person, the NRFU enumerator will return and attempt to gather information from a "proxy," such as a neighbor or landlord, who can report what he or she knows about the household and its members. Joint Stips. ¶¶ 11-13; 83 Fed. Reg. at 26649. Finally, if enumeration-by-proxy fails, the Census Bureau will then "impute" either the number of household members or their characteristics (or both) based on already-existing data from the area. See AR 1281-82, 1304. In other words, the Census Bureau will use a formula to extrapolate what it does not know about the population from what it already knows. See Tr. 1351. Because NRFU data is less accurate than self-response data, see AR 1281, the Census Bureau places a high priority on obtaining self-responses from as many households as possible, see AR 163-65. To that end, the Census Bureau partners with local organizations (which it refers to as "Trusted Partners") to encourage local households to self-respond. Joint Stips. ¶¶ 26, 28.

B. The Secretary's Authority Over the Census

Since Congress first delegated its census-related authority to an Executive Branch official, it has retained some control over the design and administration of the census. The first permanent delegation, for example, provided that the decennial census "shall be restricted to inquiries relating to the population, to mortality, to the products of agriculture and of manufacturing and mechanical establishments" and that the tabulations of population "shall comprehend for each inhabitant the name, age, color, sex, conjugal condition, place of birth, and place of birth of parents, whether alien or naturalized, number of years in the United States, occupation, months unemployed, literacy, school attendance, and ownership of farms and homes." Act of Mar. 3, 1899 § 7, 30 Stat. 1014, 1015. Within those broad confines, however, Congress provided that "the Director of the Census may use his discretion *522as to the construction and form and number of inquiries necessary to secure information." Id.

In 1976, Congress amended Title 13 substantially. See Act. of Oct. 17, 1976 ("1976 Census Act"), Pub. L. No. 94-521, 90 Stat. 2459 (codified in scattered sections of 13 U.S.C.). Among other things, the 1976 Census Act amended Section 141(a) of Title 13 to update and consolidate its delegation of authority over the census to the Secretary of Commerce. See id. § 7(a), 90 Stat. at 2461 (codified at 13 U.S.C. § 141(a) ). Section 141(a) now provides:

The Secretary shall, in the year 1980 and every 10 years thereafter, take a decennial census of population as of the first day of April of such year, which date shall be known as the "decennial census date," in such form and content as he may determine, including the use of sampling procedures and special surveys. In connection with any such census, the Secretary is authorized to obtain such other census information as necessary.

13 U.S.C. § 141(a). That delegation now sits alongside Section 5 of Title 13, which authorizes the Secretary to "prepare questionnaires," including but not only for the decennial census, and to "determine the inquiries, and the number, form, and subdivisions thereof." 13 U.S.C. § 5.

Along with - and within - that broad delegation, however, the 1976 Census Act also constrained the Secretary's delegated authority over the decennial census and its questionnaires in several significant ways. First, by its terms, Section 141(a) itself authorized the Secretary to collect information "other" than population information only "as necessary." Id. § 141(a). Second, and significantly, Congress added a new subsection to Title 13's Section 6, which had previously merely authorized the Secretary to acquire and use "pertinent" information from other federal, state, and local authorities for the purpose of gathering census-related data. See 13 U.S.C. § 6 (1970). The new subsection - Section 6(c) - added that, "[t]o the maximum extent possible and consistent with the kind, timeliness, quality and scope of the statistics required, the Secretary shall acquire and use information available from any source referred to in subsection (a) or (b) of this section instead of conducting direct inquiries." 1976 Census Act § 5(a), 90 Stat. at 2460 (codified at 13 U.S.C. § 6(c) ) (emphases added).

At the same time, Congress also cabined the Secretary's authority to collect data - other than for the straightforward purpose of counting whole persons for apportionment purposes - through nationwide inquiries of the whole population. Whereas Section 195 of Title 13 had previously merely authorized data collection through statistical sampling, the 1976 Census Act amended that provision to state that, "[e]xcept for the determination of population for purposes of apportionment of Representatives in Congress among the several States, the Secretary shall , if he considers it feasible, authorize the use of the statistical method known as 'sampling' in carrying out the provisions of this title." 1976 Census Act § 10, 90 Stat. at 2464 (codified at 13 U.S.C. § 195 ) (emphasis added); see Department of Commerce , 525 U.S. at 341, 119 S.Ct. 765 (noting that the new Section 195"changed a provision that permitted the use of sampling for purposes other than apportionment into one that required that sampling be used for such purposes if 'feasible' "). Thus, the "broad grant of authority given in § 141(a) is informed ... by the narrower and more specific § 195," Department of Commerce , 525 U.S. at 338, 119 S.Ct. 765, and is similarly limited by the narrower and more specific Section 6(c). Thus, together, *523Sections 6(c) and Section 195 effectively established a new default rule for the collection of census data other than for apportionment purposes: first, the Secretary was to "acquire and use" administrative record data instead of conducting direct surveys "to the maximum extent possible," if consistent with the type of data required, 13 U.S.C. § 6(c) ; and, second, when conducting surveys, he was required to use statistical sampling "if ... feasible," instead of asking a question of everyone, id. § 195.

That was not all. The 1976 Congress also enacted a new reporting requirement, mandating that the Secretary report to the relevant congressional committees, at least three years before the "census date" for a given census, all "subjects proposed to be included, and the types of information to be compiled." 13 U.S.C. § 141(f)(1). Further, no later than two years before the given census date, the Secretary must report to the same congressional committees all "questions proposed to be included in such census." Id. § 141(f)(2) (emphasis added). Congress authorized the Secretary to diverge from the proposals set forth in those reports, but only if he "finds new circumstances exist which necessitate that the subjects, types of information, or questions contained in reports so submitted be modified," and he submits another report "containing the Secretary's determination of the subjects, types of information, or questions as proposed to be modified." Id. § 141(f)(3).

Finally, to the extent relevant here, the 1976 Census Act's new constraints on the Secretary's authority built on another important, longstanding constraint: a sharp restriction on the authority to share any information gathered in any given data collection effort. With certain limited exceptions, Section 9 of Title 13 provides:

Neither the Secretary, nor any other officer or employee of the Department of Commerce or bureau or agency thereof, ... may ...

(1) use the information furnished under the provisions of [Title 13] for any purpose other than the statistical purposes for which it is supplied; or

(2) make any publication whereby the data furnished by any particular establishment or individual under [Title 13] can be identified; or

(3) permit anyone other than the sworn officers and employees of the Department or bureau or agency thereof to examine the individual reports.

13 U.S.C. § 9(a). Moreover, Section 9 categorically forbids anyone , "except the Secretary in carrying out the purposes of [Title 13]," from ordering the production of census reports that have been retained by the people who submitted them. Id. And it provides that copies of such census materials are both "immune from legal process" and unusable "for any purpose in any action, suit, or other judicial or administrative proceeding," without the person's consent. Id. Notably, the Secretary's authority to share data with other federal agencies, including DOJ, is "[s]ubject to the limitations contained in" Section 9 (and Section 6(c) ). Id. § 8(b). More specifically, although the Secretary is authorized to "furnish copies of tabulations and other statistical materials" to other federal agencies, those materials may "not disclose the information reported by, or on behalf of, any particular respondent." Id.

In sum, as befits a subject over which the Constitution assigns Congress "virtually unlimited discretion," Wisconsin v. City of New York , 517 U.S. 1, 19, 116 S.Ct. 1091, 134 L.Ed.2d 167 (1996), Congress has been judicious in its delegation of that authority to the Executive Branch, and it *524has retained an active role in policing the form, content, and methodology of the census through these and other provisions. That is, even as it has delegated broad authority over the census to the Secretary, Congress has taken care to limit that authority and, with respect to a few topics that it has deemed especially worthy of restraint - such as the use of survey questions instead of administrative records or the practice of asking survey questions of all respondents as opposed to sampling - Congress has enacted clear instructions for the Secretary to follow in carrying out his statutory duties. Cf. Department of Commerce , 525 U.S. at 337-39, 119 S.Ct. 765.

C. The History of a Citizenship Question on the Census

As the Court described at length in an earlier Opinion and Order, see New York v. U.S. Dep't of Commerce , 315 F.Supp.3d 766, 776-79 (S.D.N.Y. 2018), the questions posed on the census have ebbed and flowed since the first census in 1790 asked each household about "the sexes and colours of free persons," as well the age of each resident, see Act of March 1, 1790 § 1, 1 Stat. 101, 101-02 (1790). Most relevant for present purposes, a question regarding citizenship appeared for the first time on the fourth census in 1820, when Congress directed enumerators to tally the number of "Foreigners not naturalized." Act of March 14, 1820 § 1, 3 Stat. 548, 550 (1820). With one unexplained exception (the 1840 census), a question about citizenship status or birthplace appeared on every census thereafter through 1950. See New York , 315 F.Supp.3d at 776-79. That changed in 1960 - the first census after Congress authorized the use of sampling. Id. at 778. That year, only five questions were posed to all respondents, concerning the respondent's relationship to the head of household, sex, color or race, marital status, and month and year of birth.6 In a review of the census several years later, the Census Bureau explained the decision not to ask all respondents about citizenship as follows: "It was felt that general census information on citizenship had become of less importance compared with other possible questions to be included in the census, particularly in view of the recent statutory requirement for annual alien registration which could provide the Immigration and Naturalization Service, the principal user of such data, with the information it needed." U.S. BUREAU OF THE CENSUS , 1960 CENSUSES OF POPULATION AND HOUSING: PROCEDURAL HISTORY ("1960 CENSUSES OF POPULATION AND HOUSING") 194 (1966), http://www2.census.gov/prod2/decennial/documents/1960/proceduralHistory/1960proceduralhistory.zip.

Between 1970 and 2000, the Census Bureau used both a short-form questionnaire (containing only a handful of questions), which was distributed to the vast majority of the population, and a long-form questionnaire (containing both the inquiries on the short-form questionnaire as well as additional questions), which was distributed to only a sample of the population. During that time, the long-form questionnaires contained a citizenship question, but the short-form questionnaires did not. See MEASURING AMERICA 77-78, 84-85, 91-92, *525100-101. In 2010, after the advent of the ACS, the Census Bureau dropped the long-form questionnaire entirely. The 2010 census asked about such matters as "the age, sex, race, and ethnicity (Hispanic or non-Hispanic) of each person in a household," but did not ask about citizenship. WILLIAMS , THE 2010 DECENNIAL CENSUS 3. Thus, the last time that the census asked every respondent about citizenship was sixty-nine years ago, in 1950. Notably, that is before the VRA was enacted in 1965. In other words, for all fifty-four years that the VRA has existed, the federal government has never had a "hard-count" tally of the number of citizens in the country. Instead, consistent with the requirement to use statistical sampling techniques "if ... feasible" for everything other than the constitutionally mandated "actual Enumeration," see 13 U.S.C. § 195, the federal government has extrapolated from citizenship data collected from a subset of the population to model data for the population as a whole, see WILLIAMS , THE 2010 DECENNIAL CENSUS 3.

Since 1950, the Census Bureau and former Census Bureau officials have consistently opposed periodic proposals to resume asking a citizenship question of every census respondent. In 1980, for example, several plaintiffs (including the Federation for American Immigration Reform, which appears here as amicus curiae in support of Defendants, see Docket Nos. 75, 179) sued the Census Bureau, contending that the census was constitutionally required to count only citizens. See Fed'n for Am. Immigration Reform v. Klutznick , 486 F.Supp. 564 (D.D.C. 1980) (" FAIR ") (three-judge court). In that litigation, the Census Bureau argued that reinstating a citizenship question for all respondents would "inevitably jeopardize the overall accuracy of the population count" because noncitizens would be reluctant to participate, for fear "of the information being used against them." Id . at 568. Likewise, in Congressional testimony prior to the 1990 census, Census Bureau officials opposed reinstating a citizenship question for all respondents, opining that it could cause legal residents to "misunderstand or mistrust the census and fail or refuse to respond." Exclude Undocumented Residents from Census Counts Used for Apportionment: Hearing on H.R. 3639, H.R. 3814, and H.R. 4234 Before the Subcomm. on Census & Population of the H. Comm. on Post Office & Civil Serv. , 100th Cong. 47-51 (1988) (statement of John G. Keane, Director, Bureau of the Census); see also Census Equity Act: Hearings on H.R. 2661 Before the Subcomm. on Census & Population of the H. Comm. on Post Office & Civ. Serv. , 101st Cong. 42-44 (1989) (statement of C. Louis Kincannon, Deputy Director, Bureau of the Census). Before the 2010 census, former Bureau Director Kenneth Prewitt testified before Congress to the same effect. See Counting the Vote: Should Only U.S. Citizens Be Included in Apportioning Our Elected Representatives?: Hearing Before the Subcomm. on Federalism & the Census of the H. Comm. on Gov't Reform , 109th Cong. 72 (2005) (statement of Kenneth Prewitt). Just two years ago, four former Census Bureau Directors wrote in an amicus curiae brief to the Supreme Court (in a case about the use of total population in intrastate redistricting) that a "citizenship inquiry would invariably lead to a lower response rate to the Census." Brief of Former Directors of the U.S. Census Bureau as Amici Curiae in Support of Appellees at 25, Evenwel v. Abbott , 136 S.Ct. 1120 (2016) (No. 14-940), 2015 WL 5675832, at *25.7

*526D. Testing and Adding New Questions to the Census

The Census Bureau's longstanding opposition to a citizenship question on the census is consistent with a more general reluctance to tinker with the questionnaire unnecessarily. That is, although early census questionnaires changed regularly, a more sophisticated understanding of statistics and survey design in the modern era has caused the Census Bureau to approach any changes to the questionnaire with great care. For instance, after the 1990 census, the Census Bureau considered adding a question regarding respondents' Social Security Numbers ("SSNs") to the "short-form" questionnaire. See Tr. 998-99. Before deciding to add such a question, however, the Census Bureau conducted a randomized controlled trial comparing a version of the questionnaire that asked about SSNs to one that did not in order to assess the question's impact on self-response rates. See id. at 999. Overall, the Census Bureau observed a 3.4% decline in self-response rates attributable to the question, a decline that was not evenly distributed among subpopulations. See id. at 999-1000. In part due to these results, the Census Bureau did not - and does not to this day - ask a question about SSNs on the decennial census. See id. at 999.

As the SSN example reflects, in recent decades, the Census Bureau has followed a fairly robust process in evaluating whether to add a new question to a survey such as the census. AR 9865, 9867; AR 3560; AR 3890-91; Docket No. 516-1 ("Thompson Decl."), ¶¶ 45, 47-49. The process usually begins with a request from Congress or an Executive Branch agency to add a question. AR 3890; see AR 2304. After receiving such a request, the Census Bureau works with the Office of Management and Budget ("OMB") to ensure that the proposed data collection would comply with applicable legal and regulatory requirements. AR 3890. If the Census Bureau determines that adding the new question is "warranted," the Secretary of Commerce notifies Congress of his intent to add the question - first by including the subject of the question in the Section 141(f)(1) report to Congress, at least three years before the census date and, later, by reporting the question itself in the Section 141(f)(2) report, at least two years before the census date. Id. The Census Bureau must then test the wording of the new question. AR 3891. Pre-testing requires approval from OMB and a process that includes notifying the public and inviting comment through a notice in the Federal Register. Id. After the Census Bureau has responded to comments, OMB can approve the test. Id. Once the question has been tested, the Census Bureau must redesign the questionnaires (or internet collection systems), including translation into non-English languages, and redevelop training procedures for enumerators. Id. Finally, the Census Bureau must submit the final questionnaire to OMB for approval. Id.

This process is subject to several sets of guidelines and standards governing collection of statistical data. First, since 2006, the design and administration of governmental surveys - including the census - have been subject to OMB's Standards and Guidelines for Statistical Surveys . PX-260, at ii; see 79 Fed. Reg. 71610 (Dec. 2, 2014) ; PX-359; see also Docket No. 498-11 ("Habermann Aff."), ¶ 20. Several provisions of the OMB Standards and Guide lines *527are relevant here. First, Statistical Directive Number 1 requires that "a Federal statistical agency must be independent from political and other undue external influence in developing, producing, and disseminating statistics." 79 Fed. Reg. at 71612. Second, Standard 2.3 states that "[a]gencies must design and administer their data collection instruments and methods in a manner that achieves the best balance between maximizing data quality and controlling measurement error while minimizing respondent burden and cost." PX-359, at ii. Finally, Guideline 2.3.1 states: "Design the data collection instrument in a manner that minimizes respondent burden, while maximizing data quality." Id. at 11.

Additionally, in 2010, the Census Bureau adopted a comprehensive set of "Statistical Quality Standards." PX-260, at vii. The Standards require pre-testing of any questions to be added to data-collection products such as the census questionnaire. See id. at 8. Sub-Requirement A2-3.3 of the Standards requires that "[d]ata collection instruments and supporting materials must be pretested with respondents to identify problems (e.g., problems related to content, order/context effects, skip instructions, formatting, navigation, and edits) and then refined, prior to implementation, based on the pretesting results." Id. at 8 (emphasis added). Sub-Requirements A2-3.3-1c and A2-3.3-1d further provide that pretesting must be performed when "[r]eview by cognitive experts reveals that adding pretested questions to an existing instrument may cause potential context effects" and when "[a]n existing data collection instrument has substantive modifications (e.g., existing questions are revised or new questions added)." Id. The Standards note that, "[o]n rare occasions, cost or schedule constraints may make it infeasible to perform complete pretesting. In such cases, subject matter and cognitive experts must discuss the need for and feasibility of pretesting. The program manager must document any decisions regarding such pretesting, including the reasons for the decision. If no acceptable options for pretesting can be identified, the program manager must apply for a waiver." Id. The Standards provide for another exception to the pretesting requirement: "Pretesting is not required for questions that performed adequately in another survey." Id.

E. Secretary Ross's Decision and This Litigation

As noted above, the Census Act requires the Secretary of Commerce to submit a report to the relevant congressional committees at least three years before any given census listing the "subjects proposed to be included, and the types of information to be compiled" on the census. 13 U.S.C. § 141(f)(1). Consistent with that requirement, in March 2017 - approximately one month after his confirmation by the Senate - Secretary Ross submitted a report to Congress titled "Subjects Planned for the 2020 Census and American Community Survey." See AR 194-270. The report listed as the planned subjects for the 2020 census questionnaire the very same subjects that had appeared on the 2010 census questionnaire: age, gender, race/ethnicity, relationship, and tenure (that is, whether the respondent's home in question is owned or rented). See AR 204-13. The list of subjects did not include citizenship status.

On March 26, 2018, however, Secretary Ross issued a memorandum directing the Census Bureau to reinstate a question about citizenship status on the 2020 census questionnaire. See AR 1313-20 ("Ross Memo"). In his memorandum, Secretary Ross asserted that his decision was *528prompted by a letter from DOJ, dated December 12, 2017, which requested reinstatement of the citizenship question to facilitate enforcement of Section 2 of the VRA. See Ross Memo 1, at AR 1313. A few days later, Secretary Ross submitted another report to Congress (of which the Court can and does take judicial notice) titled "Questions Planned for the 2020 Census and American Community Survey." See PX-489. The report included the following planned question about citizenship:

Id. at 7. It stated that a question about citizenship had been "asked since 1820." Id. ; see id. n.1 ("Citizenship asked 1820, 1830, 1870, and 1890 to present."). And it asserted that the question is "USED TO CREATE STATISTICS ABOUT CITIZEN AND NONCITIZEN POPULATIONS," which "are essential for enforcing the Voting Rights Act" and "is of interest to researchers, advocacy groups, and policymakers." Id. (capitalization in original).

Eight days after Secretary Ross's March 26, 2018 memorandum announcing his decision, the first of these cases - brought by a coalition of states and local governmental entities (the "Governmental Plaintiffs") - was filed. See Docket No. 1. The Governmental Plaintiffs are comprised of eighteen states (New York, Colorado, Connecticut, Delaware, Illinois, Iowa, Maryland, Massachusetts, Minnesota, New Jersey, New Mexico, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, and Washington) and the District of Columbia, fifteen cities and counties (the cities of Central Falls, Chicago, Columbus, New York, Philadelphia, Phoenix, Pittsburgh, Providence, and Seattle; the city and county of San Francisco; and the counties of Cameron, El Paso, Hidalgo, and Monterey), and the United States Conference of Mayors. See Governmental Plaintiffs' Second Amended Complaint ("SAC"), Docket No. 214. On June 6, 2018, the second case - brought by a coalition of nongovernmental organizations (the "NGO Plaintiffs") - was filed. See NGO Plaintiffs' Complaint ("NGO Compl."), 18-CV-5025, Docket No. 1. The NGO Plaintiffs are comprised of New York Immigration Coalition ("NYIC"), CASA de Maryland ("CASA"), American-Arab Anti-Discrimination Committee ("ADC"), ADC Research Institute ("ADCRI"), and Make the Road New York ("MRNY").See id. In each case, Plaintiffs alleged that Secretary Ross's decision to reinstate a citizenship question violated both the APA and the Enumeration Clause of the Constitution. The NGO Plaintiffs argued as well that the decision violated the equal protection component of the Fifth Amendment's Due Process Clause.

*529The procedural history of these cases has been somewhat unusual because, among other things, Defendants filed multiple petitions for mandamus challenging discovery orders issued by the Court and corresponding applications - to this Court, the Second Circuit, and the Supreme Court - to stay proceedings pending adjudication of those petitions. See New York v. U.S. Dep't of Commerce , No. 18-CV-2921 (JMF), 2018 WL 6060304, at *1 n.1 (S.D.N.Y. Nov. 20, 2018) (detailing this history). For present purposes, two pieces of that procedural history warrant mention. First, in May and June 2018, Defendants moved to dismiss all of Plaintiffs' claims. See Docket No. 154; 18-CV-5025, Docket No. 38. On July 26, 2018, the Court granted those motions in part and denied them in part. See New York , 315 F.Supp.3d at 811-12. The Court denied the motions with respect to Plaintiffs' claims under the APA and the Due Process Clause, finding, among other things, that the NGO Plaintiffs had alleged a plausible claim of invidious discrimination in violation of the Fifth Amendment's Due Process Clause. See id. at 806-08. By contrast, the Court held that Plaintiffs failed to state a claim under the Enumeration Clause. "That conclusion," the Court reasoned, was "compelled not only by the text of the Clause, which vests Congress with virtually unlimited discretion in conducting the census, but also by historical practice," namely "that, since the very first census in 1790, the federal government has consistently used the decennial exercise not only to obtain a strict headcount ..., but also to gather demographic data about the population on matters such as race, sex, occupation, and, even citizenship." Id. at 774.

Second, around the same time, Plaintiffs moved for relief related to the "Administrative Record" - the record, compiled and submitted by Defendants, of materials "upon which the Secretary of Commerce based his decision." Docket Nos. 173, 173-1; see Docket No. 193. To the extent relevant here, Plaintiffs moved for two forms of relief: first, an order compelling Defendants to "complete" the Administrative Record; and second, an order authorizing discovery "outside" the Administrative Record. See Docket No. 193, at 1. In an oral ruling on July 3, 2018, the Court granted both requests. With respect to the former, the Court found that the Administrative Record did not constitute the "whole record" - namely, the "full scope of" materials that Secretary Ross had considered, whether directly, "indirectly," or "constructively." Docket No. 208 ("July 3rd Tr."), at 79-82. And with respect to the latter, the Court found that Plaintiffs had "made a strong preliminary showing or prima facie showing that they will find material beyond the Administrative Record indicative of bad faith" or pretext. Id. at 85. Notably, Defendants did not immediately challenge the Court's ruling authorizing discovery beyond the Administrative Record (and have never challenged its ruling with respect to completing the Administrative Record). Several months later, however, after the Court authorized depositions of Secretary Ross and a DOJ official, Defendants challenged those rulings by way of petitions for mandamus, tacking on a challenge to the Court's initial discovery Order. Eventually, the Supreme Court agreed to hear one such challenge (treating Defendants' mandamus petition as a petition for certiorari), In re Dep't of Commerce , --- U.S. ----, 139 S.Ct. 566, 202 L.Ed.2d 400, 2018 WL 5458822 (Nov. 16, 2018) ; and stayed the deposition of Secretary Ross pending its decision, but otherwise allowed these proceedings to continue, see In re Dep't of Commerce , --- U.S. ----, 139 S.Ct. 16, 202 L.Ed.2d 306 (2018) (mem.).8 The case proceeded to trial, without *530a jury, on November 5, 2018. After extensive post-trial briefing (Plaintiffs' briefs, alone, totaled 502 pages), the Court held closing arguments on November 27, 2018.9

SECRETARY ROSS'S DECISION

With that as background, the Court turns to the process and basis for Secretary Ross's March 26, 2018 decision. In light of the pending Supreme Court challenge to the Court's decision authorizing extra-record discovery and the limited time to resolve Plaintiffs' claims before the 2020 census questionnaires need to be printed, the Court begins with an account that is based exclusively on the initially filed Administrative Record and then turns to what the evidence beyond that portion of the Administrative Record reveals.10

A. The Initial Administrative Record Submission

1. Defendants first filed what they characterized as the Administrative Record on June 8, 2018. See Docket No. 173. That submission was 1,320 pages and included the December 12, 2017 DOJ letter requesting addition of a citizenship question to the census questionnaire; various analyses of that request by the Census Bureau; and Secretary Ross's March 26, 2018 memorandum. These pages reveal that the Census Bureau repeatedly and consistently recommended against addition of a citizenship question to the census questionnaire based on its assessment that adding the question would reduce self-response rates, thereby increasing costs and harming the overall data and integrity of the census, and that DOJ's stated interest in having more granular citizenship data could be satisfied in a less costly, more effective, and less harmful manner. More importantly, for the purposes of this Court's review, the initial Administrative Record submission alone contains overwhelming evidence to that effect, and none that contradicts it.

1. The December 12, 2017 DOJ Letter

2. Secretary Ross asserted in his March 26, 2018 memorandum that his decision to add the citizenship question to the census questionnaire was prompted by a December 12, 2017 letter from DOJ. The letter came from Arthur E. Gary of the Justice Management Division; it was addressed to then-Acting Director Jarmin. See AR 663-65 (the "Gary Letter"); AR 1525-27 (same). In the letter, DOJ "formally *531request[ed] that the Census Bureau reinstate on the 2020 Census questionnaire a question regarding citizenship, formerly included on the so-called 'long form' census." Gary Letter 1, at AR 663. "This data," the Letter stated, "is critical to the Department's enforcement of Section 2 of the Voting Rights Act and its important protections against racial discrimination in voting. To fully enforce those requirements, the Department needs a reliable calculation of the citizen voting-age population in localities where voting rights violations are alleged or suspected." Id.

3. More specifically, the Gary Letter noted that the Supreme Court had "held that Section 2 of the Voting Rights Act prohibits 'vote dilution' by state and local jurisdictions engaged in redistricting, which can occur when a racial group is improperly deprived of a single-member district in which it could form a majority." Gary Letter 1, at AR 663 (citing Thornburg v. Gingles , 478 U.S. 30, 50, 106 S.Ct. 2752, 92 L.Ed.2d 25 (1986) ). Further, "[m]ultiple federal courts of appeals have held that, where citizenship rates are at issue in a vote-dilution case, citizen voting-age population" - often referred to as "CVAP" - "is the proper metric for determining whether a racial group could constitute a majority in a single-member district." Id. (citing cases). "These cases," the Gary Letter reasoned, "make clear that, in order to assess and enforce compliance with Section 2's protection against discrimination in voting, the Department needs to be able to obtain citizen voting-age population data for census blocks, block groups, counties, towns, and other locations where potential Section 2 violations are alleged or suspected." Gary Letter 2, at AR 664.

4. The Gary Letter noted that DOJ had previously relied on citizenship data acquired through either the "long form" census questionnaire or the ACS. See id. The Gary Letter asserted, however, that citizenship data acquired through the ACS is not "ideal ... for such purposes" for four reasons. Gary Letter at 2-3, at AR 664-65. First, "[j]urisdictions conducting redistricting, and the Department in enforcing Section 2, already use the total population data from the census to determine compliance with the Constitution's one-person, one-vote requirement," such that "using the ACS citizenship estimates means relying on two different data sets, the scope and level of detail of which vary quite significantly." Id. at 2, at AR 664. Second, ACS surveys are conducted annually and produce data that are "aggregated into one-year, three-year, and five-year estimates," and thus "do not align in time with the decennial census data," whereas "[c]itizenship data from the decennial census ... would align in time with the ... data from the census that jurisdictions already use in redistricting." Id. at 3, at AR 665. Third, "ACS estimates are reported at a ninety percent confidence level" (that is, as a statistical sample with a margin of error that "increases as the sample size - and thus, the geographic area - decreases"), whereas "decennial census data is a full count of the population." Id. And finally, decennial "Census data is reported to the census block level, while the smallest unit reported in the ACS estimates is the census block group," requiring DOJ in some instances to "perform further estimates" of CVAP at the census block level. Id.

5. "For all of these reasons," the Gary Letter concluded, DOJ "believes that decennial census questionnaire data regarding citizenship, if available, would be more appropriate for use in redistricting and in Section 2 litigation than the ACS citizenship estimates." Id. On that basis, the Gary Letter "formally request[ed]" that the Census Bureau "reinstate" a citizenship question on the 2020 census. Id. "At *532the same time," however, the Gary Letter "request[ed] that the [Census] Bureau also maintain the citizenship question on the ACS, since such question is necessary, inter alia , to yield information for the periodic determinations made by the Bureau under Section 203 of the Voting Rights Act." Id.11

2. The Census Bureau's Preliminary Analyses and Recommendations

6. Following receipt of the Gary Letter, experts at the Census Bureau - acting under the supervision of Dr. John M. Abowd, the Bureau's Chief Scientist and Associate Director for Research and Methodology - sought to determine the effects of adding a citizenship question to the census questionnaire and whether there were alternative means to satisfy DOJ's interest in more granular citizenship data. The Census Bureau's initial analyses and recommendations were memorialized in memoranda dated December 22, 2017, see AR 11634-45 (the "December 22 Memo"); see also AR 5500-11 (copy of the same); January 3, 2018, see AR 5473-75 (the "January 3 Memo");12 and January 19, 2018, see AR 1277-85 (the "January 19 Memo").13

7. The December 22 Memo included two significant conclusions. First, the Memo opined that the Census Bureau could "potentially" obtain "a more accurate measure of citizenship" in a more "cost efficient" manner by using means other than a question on the census. December 22 Memo, at AR 11644. The Memo identified four existing surveys, including the ACS, through which the Census Bureau obtained "directly reported" citizenship data, as well as a slew of "administrative record[s]" (that is, records from other federal agencies or states) with similar information that the Census Bureau had or could acquire. Id. at AR 11634-35. The administrative records included Numident, a Social Security Administration ("SSA") dataset that represents "the most complete and reliable administrative record source of citizenship data currently available," and citizenship data maintained by the U.S. Customs and Immigration Service ("USCIS"). Id. at AR 11636, 11643-44.

8. Second, the December 22 Memo concluded that including a citizenship question in the 2020 census questionnaire was likely to depress self-response rates, particularly among noncitizen households; increase costs; and produce lower quality citizenship data. Id. at AR 11639-45. The Memo explained that including a citizenship question could lower the rate of voluntary compliance, which would require expanded field operations that "require additional unnecessary costs and burden to the Bureau." Id. at AR 11644-45.

9. The December 22 Memo recommended that the best way to "support[ ]

*533redistricting in the manner requested by the Department of Justice is" not to add a citizenship question to the census, but "to make a citizenship variable available on the 2020 Census Edited File (CEF)." Id. at AR 11644. The CEF is "the internal, confidential data file" that underlies the census data set used by DOJ in redistricting, known as the "PL94 tabulations." Id . If citizenship were available on the CEF, the Memo explained, the PL94 tabulations could be restructured to include direct estimates of CVAP by race and ethnicity at the census block level. See id . "These tabulations would have essentially the same accuracy as current PL94 and Summary File 1 (SF1) data." Id .

10. On the afternoon of December 22, 2017, Dr. Jarmin emailed Arthur Gary at DOJ, stating that "the best way to provide PL94 block-level data with citizen voting population by race and ethnicity would be through utilizing a linked file of administrative and survey data the Census Bureau already possesses. This would result in higher quality data produced at lower cost." AR 3289.

11. The January 3 Memo from Dr. Abowd to Dr. Jarmin expanded on the December 22 Memo's analyses and recommendations. See January 3 Memo, at AR 5473-75. The January 3 Memo described "three alternatives for meeting the DoJ request." Id. at AR 5473.

12. Under Alternative A, the Census Bureau would "[m]aintain the status quo for data collection, preparation, and publication," but would prepare a "special product" for DOJ containing the Census Bureau's "best estimate of block-level citizen voting age population by race and ethnicity," similar to what the Census Bureau prepares for use in connection with Section 203 of the VRA. Id. Alternative A would cost an extra $200,000 and would produce similar-quality data to that produced for Section 203 purposes. Id. at AR 5474.

13. The January 3 Memo concluded that Alternative B - adding a citizenship question to the 2020 census questionnaire - would "most likely deliver higher quality block-level citizen voting age population by race and ethnicity data than Alternative A." Id. But it would cost an estimated additional $27.5 million and, based on an estimated minimum 5.1% decline in self-response among noncitizen households, would lead to an estimated minimum "154,000 fewer correct enumerations." Id.14

14. Finally, the January 3 Memo addressed Alternative C, the option the December 22 Memo had recommended (although not by that name). See December 22 Memo, at AR 11644. Under Alternative C, the Census Bureau would not add a citizenship question to the questionnaire, but would "[a]dd the capability to link an accurate, edited citizenship variable from administrative records to the final 2020 Census microdata files." January 3 Memo, at AR 5473. In that way, Alternative C would provide block-level tabulations of CVAP by race and ethnicity. Id. It would deliver "higher quality data than Alternative B for DoJ's stated uses" because the "primary data sources for the administrative record citizen variable require proof of *534citizenship" and, thus, are "very accurate." Id. at AR 5475.

15. Based on this analysis, the January 3 Memo opined that "Alternative A is not very costly and does not harm the quality of the census count"; that "Alternative B better addresses DoJ's stated uses," but "is very costly and does harm the quality of the census count"; and that "Alternative C even better meets DoJ's stated uses, is comparatively far less costly than Alternative B, and does not harm the quality of the census count." Id. "For these reasons," the Memo concluded, "we recommend Alternative C for meeting the Department of Justice data request." Id.

16. The January 19 Memo contained a "Technical Review" of the facts and the Census Bureau's analysis of Alternatives A, B, and C. January 19 Memo, at AR 1277-85.

17. The January 19 Memo described Alternative A in more detail, explaining that existing "redistricting and CVAP data are used by the Department of Justice to enforce the Voting Rights Act" and "by state redistricting offices to draw congressional and legislative districts that conform to constitutional equal-population and Voting Rights Act nondiscrimination requirements. Because the block-group-level CVAP tables have associated margins of error, their use in combination with the much more precise block-level census counts in the redistricting data requires sophisticated modeling. For these purposes, most analysts and the DoJ use statistical modeling methods to produce the block-level eligible voter data that become one of the inputs to their processes." Id. at AR 1279. Without modifying any of its other procedures, the January 19 Memo explained, the Census Bureau could deploy "a small team of Census Bureau experts similar in size and capabilities to the teams used to provide the Voting Rights Act Section 203 language determinations" to assist DOJ in making those calculations. Id. The January 19 Memo updated the cost of Alternative A to $350,000, and estimated that it would "have no impact on the quality of the 2020 Census." Id.

18. The January 19 Memo also presented an updated analysis of Alternative B. Id. at AR 1279-82. It explained bluntly that adding a citizenship question to the census "is very costly, harms the quality of the census count, and would use substantially less accurate citizenship status data than are available from administrative sources." Id. at AR 1277. The Memo summarized "[t]hree distinct analyses" showing that the addition of a citizenship question would lead to "an adverse impact on self-response" to the census questionnaire and, consequently, "on the accuracy and quality of the 2020 Census." Id. at AR 1280. First, the Memo described evidence that a citizenship question would increase "item nonresponse rates" - that is, omitted answers to the question - and would do so disproportionately among Hispanics. Id. Second, the Memo described evidence that a citizenship question would decrease "self-response rates" - that is, the rate at which households voluntarily respond to the questionnaire - and would do so disproportionately among noncitizen households. Id. at AR 1280-81. Third, the Memo described evidence that a citizenship question would increase "breakoff rates" - that is, the rate at which households stop answering the questionnaire when they come to a particular question - and would do so disproportionately among Hispanics. Id. at AR 1281.

19. The updated analysis of Alternative B included more detail on its high cost. Id. at AR 1281-82. The reduction in self-response rates caused by the citizenship question, the January 19 Memo explained, would lead to more people being counted *535through the Census Bureau's NRFU (that is, Non-Response Follow-Up) procedures. Id. at AR 1280. The greater use of NRFU procedures produces, in turn, lower-quality data because the NRFU procedures yield more "erroneous enumerations" and "whole-person imputations" than self-responses do. Id. at AR 1281.15 Using the "conservative" estimate that addition of a citizenship question would cause a 5.1% decline in self-response among noncitizen households, the January 19 Memo explained that adding a citizenship question would produce 432,000 fewer correct enumerations and would cost at least $27.5 million more. Id. at AR 1282. The Memo stressed that its estimates of the decline in data quality and increase in cost associated with Alternative C were "conservative" and that the true numbers could be "much greater." Id.

20. The January 19 Memo also discussed Alternative C in more depth. It summarized the Census Bureau's evidence that Alternative C - linking a citizenship variable from administrative records to the census microdata files - "is comparatively far less costly than Alternative B, does not increase response burden, and does not harm the quality of the census count." AR 1277. The Memo noted that the Census Bureau had been testing its ability to link administrative data to census data in that manner since the 1990 census. Id. For the 2020 census, the Census Bureau had already begun "regularly ingesting and loading administrative data from the Social Security Administration, Internal Revenue Service and other federal and state sources into the 2020 Census data systems." Id.

21. Significantly, in its analysis of Alternative C, the January 19 Memo again noted that Alternative C was likely to yield more accurate citizenship data than Alternative B would yield. See id. at AR 1277. First, the Memo explained that comparisons of ACS data and federal administrative records revealed that somewhere between 23.8% and 30% of people whom administrative records indicate are noncitizens report that they are citizens on the ACS. See id. at AR 1283. This suggests that self-reported citizenship status is of dubious accuracy. Second, the sampling techniques used for ACS data may not accurately predict the citizenship status of those who do not respond. The sampling techniques assume that those who do not respond to any given question are statistically similar to those who do - an assumption contradicted by the data. See id. at AR 1283-84. As a result, the ACS imputes citizenship responses based on data that is not predictive of the missing set. See id .

22. The January 19 Memo acknowledged that the Numident database might be missing citizenship data for older citizens who obtained SSNs before the SSA required proof of citizenship, for naturalized citizens who have not communicated the fact of their naturalization to the SSA, and for noncitizens who do not have a SSN or other taxpayer identification number. Id. at AR 1285. "All three of these shortcomings," however, "are addressed by adding data from [USCIS]." Id. Accordingly, the Memo concluded, "the administrative records citizenship data would most likely have both more accurate citizen status and *536fewer missing individuals than would be the case for any survey-based collection method." Id. (emphasis added). The January 19 Memo estimated that the cost of using administrative records to obtain block-level CVAP data would be between $500,000 and $2 million. Id.

3. Secretary Ross's February 12, 2018 Meeting with the Census Bureau

23. On February 12, 2018, Secretary Ross met with Dr. Abowd and others from the Census Bureau to discuss the various alternatives. See AR 9450. The Administrative Record contains only one document concerning what was discussed at the meeting: an email dated February 13, 2018, from an attendee at the meeting, "identif[ying]" action items and items for future consideration that were discussed at the meeting. AR 9450. The Administrative Record otherwise contains no record - contemporaneous or otherwise - of what was discussed during the meeting. Nor is there is any indication in the Administrative Record of any other meeting between Secretary Ross and Census Bureau officials.

24. The Administrative Record does reveal that sometime before March 1, 2018, Secretary Ross asked the Census Bureau to analyze a fourth option - "Alternative D" - that would combine Alternative B (adding a citizenship question to the 2020 census) and Alternative C (relying on administrative records to generate block-level CVAP data). See AR 1308-12 ("March 1 Memo"), at AR 1309.

4. The Census Bureau's Analysis of Alternative D

25. Dr. Abowd transmitted a detailed analysis of Alternative D to Secretary Ross in a memorandum dated March 1, 2018. The March 1 Memo explained at length that Alternative D (combining the addition of a citizenship question to the census with the use of administrative records) would entail "all the negative cost and quality implications of Alternative B" (that is, simply adding the citizenship question) and would still produce "poorer quality citizenship data than Alternative C" (that is, linking data from administrative records to data from the census). See March 1 Memo at AR 1312.

26. The March 1 Memo described, first, how the various sources of administrative records interact to supplement and correct for one another's "gaps." See id. at AR 1309-10. It then identified seven "[r]emaining citizenship data gaps" in the administrative records: (1) "U.S. citizens from birth with no SSN or U.S. passport"; (2) U.S. citizens from birth born outside the United States without a passport who applied for an SSN before they were required to provide proof of their citizenship to do so; (3) U.S. citizens naturalized before 2001 who did not inform the SSA of their naturalization; (4) U.S. citizens who were automatically naturalized if they were under eighteen when their parents were naturalized after 1999, but did not inform USCIS or receive a U.S. passport; (5) lawful permanent residents ("LPRs") who obtained that status before 2001, but lack an SSN or received an SSN before the SSA asked about citizenship; (6) noncitizen, non-LPR residents who do not have an SSN (or other taxpayer identification number) and who have not applied for a visa extension; and (7) persons for whom citizenship does appear in administrative records, but for whom it is not possible to link those records with decennial census data. Id. at AR 1310-11.

27. The March 1 Memo explained that, perhaps counterintuitively, "survey data" (that is, data from a citizenship question) would not "help fill the ... gaps" in the administrative records. Id. at AR 1311.

*537This is because a "significant, but unknown, fraction" of people whose citizenship status is unknown fall into "Category Six": noncitizen, non-LPR residents without SSNs or taxpayer IDs. These people have a "strong incentive to provide an incorrect answer" or no answer to a citizenship question. Id . And, because "there is no feasible method of independently verifying their non-citizen status," identifying false reports of citizenship on the census would be "an inexact science." Id . Instead of doing that inexact science, the "survey response[s] of 'citizen' would be accepted as valid" for large numbers of people who are not, in fact, citizens. See id. Making matters worse, if a household does not self-respond in order to protect one household member in Category Six, this problem would apply to the entire household. See id. at AR 1311-12.

28. Second, the March 1 Memo explained that, like Alternative B, Alternative D would lower self-response rates and "push[ ] more households into ... NRFU." Id. at AR 1311. That would lower the quality of the data in two ways. First, as explained above, NRFU procedures yield more "erroneous enumerations" and "whole-person imputations" than self-responses do. January 19 Memo, at AR 1281. Second, NRFU procedures produce more responses that cannot be linked to administrative records (due to lower-quality personal identifying information) and linking to administrative records helps improve the accuracy of the survey data. See March 1 Memo, at AR 1311. For responses gathered through NRFU procedures, only 81.6% can be linked to people recorded in administrative records, compared to 96.7% for self-responses in the 2010 census. Id .

29. Additionally, the March 1 Memo concluded that Alternative D would likely increase the number of proxy responses required, another less accurate type of enumeration. See id. This is because those who do not self-respond because of the presence of the citizenship question are especially likely not to respond in NRFU as well. See id. Proxy responses also lead to even lower rates of linkage to administrative data on citizenship: only 33.8%. See id.

30. The March 1 Memo concluded that Alternative D was plainly inferior to Alternative C: It "would result in poorer quality citizenship data than Alternative C," and it "would still have all the negative cost and quality implications of Alternative B" summarized in the January 19 Memo. Id. at AR 1312. The March 1 Memo remarked that "[u]sing the 2020 Census data only to fill in gaps for persons without administrative data on citizenship would raise questions about why 100 percent of respondents are being burdened by a citizenship question to obtain information for the two percent of respondents where it is missing." Id .

31. In another memorandum, undated but obviously written in this same March 2018 timeframe, Dr. Abowd presented Secretary Ross with numerical estimates illustrating the differences between Alternative C and Alternative D. See AR 1304-06 ("Key Differences Memo"). The Key Differences Memo illustrated that, under Alternative C, the Census Bureau expected to link 295 million people - 89.4% of the population - to high-quality citizenship data. Id. at AR 1306. It would be unable to identify the citizenship status of 35 million people through linking, leaving those to be modeled. Id. The Key Differences Memo illustrated these numbers for Alternative C in the following flowchart:

*538AR 1306.

32. The Key Difference Memo explained that, under Alternative D, the Census Bureau expected to receive responses to the citizenship question from 294.6 million people. See id. at AR 1307. Of those responses, 263 million could be confirmed through linkages to administrative records; 9.5 million responses could be linked to, but would be inconsistent with , citizenship data in administrative records; and 22.2 million responses would not be linked to administrative records at all. See id. On top of that, the Census Bureau expected that approximately 35.4 million people's citizenship would not be measured by the 2020 census, either due to non-response or NRFU failure. See id. Approximately 21.5 million non-respondents could be linked to administrative records containing citizenship data, while approximately 13.8 million would have to have their citizenship status modeled. See id. Once again, the Key Differences Memo illustrated the numbers for Alternative D with a flowchart:

AR 1307.

33. These numbers reveal that Alternative D would produce more people who *539could not be linked to administrative records: 36 million people in Alternative D as compared to 35 million in Alternative C. See id. at AR 1306-07. Of the unlinked people in Alternative D, 13.8 million would have their citizenship modeled (or "imputed"), see id. at AR 1307, while 22.2 million would have their citizenship status evaluated through their census responses, despite the known likelihood that a high rate of noncitizens (just under 500,000, according to the Census Bureau's estimate) would be incorrectly enumerated as citizens through the survey process. See id. at AR 1305-07; March 1 Memo, at AR 1311. That would leave 9.5 million people whose census responses would conflict with administrative records. See Key Differences Memo, at AR 1307. For these people, the "[h]istoric Census Bureau practice is to use self-reported data in these situations," even though "the Census Bureau now knows from linking ACS responses on citizenship to administrative data that nearly one third of noncitizens in the administrative data respond to the questionnaire indicating they are citizens, indicating that this practice should be revisited in the case of measuring citizenship." Id. at AR 1305.

34. Put differently, Alternative D would provide no improvement to the citizenship data available under Alternative C for 90.4% of the population. For 6.7% of the population, Alternative D would produce lower quality data than Alternative C because the Census Bureau would have to use survey responses that are, generally speaking, less accurate than the imputation methods the Census Bureau would deploy under Alternative C. See id. And finally, for 2.9% of the population, Alternative D would create a problem that would not exist under Alternative C: conflicts between the survey data and the administrative data, with no reliable method for discerning accurate data amidst the conflict. See id.

35. The Key Differences Memo summarized the implications of these comparative predictions. He acknowledged that "all possible measurement methods will have errors" and that the Census Bureau "cannot quantify the relative magnitude of the errors across the alternatives at this time." Id. at AR 1305. Nevertheless, Alternative C would involve some risk of error in the administrative record data, but that would be "relatively limited" thanks to the procedures used by the SSA, USCIS, and the State Department. Id. Alternative C would also be subject to some prediction error in the 35 million cases that would have to be modeled, which would be a similar, but lesser issue in Alternative D. Id. By contrast, Alternative D would be subject to an error that is "only an issue in Alternative D": the "response error." Id. Dr. Abowd noted that while "[s]tatisticians often hope" that such response errors "are random and cancel out," the Census Bureau "know[s] from prior research" that they are "systematically biased for a subset of noncitizens." Id.

5. Communications with Stakeholders

36. While the Census Bureau was analyzing the citizenship question, the Commerce Department was communicating with stakeholders about the question. At the February 12, 2018 meeting with Dr. Abowd and other representatives of the Census Bureau, Secretary Ross requested a list of stakeholders with whom to discuss the addition of the citizenship question to the census. See AR 9450. During the outreach to stakeholders after the meeting, however, Commerce Department officials struggled to find anyone willing to express support for adding the question. See AR 3274-75 ("Email re AEI"); AR 4853-55 (same).

*54037. For example, on February 13, 2018 - only one day after the meeting with Secretary Ross - Dr. Jarmin emailed someone at the American Enterprise Institute ("AEI"): "We are trying to set up some meetings for Secretary Ross to discuss the proposed citizenship question on the 2020 Census with interested stakeholders. Most stakeholders will speak against the proposal. We're looking to find someone thoughtful who can speak to the pros of adding such a question ." Email re AEI, at AR 3275 (emphasis added). Later the same day, Michael Strain of the AEI responded: "None of my colleagues at AEI would speak favorably about the proposal. Is it important that the person actually be in favor of the proposal?" Id .

38. Dr. Jarmin responded the same day, noting: "We are trying to find someone who can give a professional expression of support for the proposal in contrast to the many folks we can find to give professional statements against the proposal. Interesting, but perhaps not so surprising, that no one at AEI is willing to do that." AR 8325. Less than two minutes later, Dr. Jarmin forwarded his email exchange with the AEI to then-Under Secretary for Economic Affairs, Karen Dunn Kelley, noting: "Appears no one at AEI willing to speak in favor of putting question on the 2020." Id. at AR 3274.16 The Administrative Record reflects that only two organizations supported the citizenship question: the Center for Immigration Studies and the Heritage Foundation. See AR 1206; AR 8325.

39. By contrast, between December 12, 2017 (the date of the Gary Letter) and March 26, 2018 (the date of Secretary Ross's decision), the Commerce Department received many communications opposing addition of a citizenship question to the census, from former directors of the Census Bureau, business groups, civil rights groups, social science groups, members of Congress, and state and local officials. See generally Plaintiffs' Joint Proposed Post-Trial Findings of Fact, Docket No. 545 ("Pls.' Proposed Findings"), ¶¶ 674-724.

40. For instance, on January 5, 2018, the American Sociological Association ("ASA") wrote to Secretary Ross to urge him to reject DOJ's proposal to add a citizenship question. See AR 787. The ASA letter predicted that if a citizenship question were added, "the integrity of the 2020 Census data will be fundamentally compromised."Id. "Including a citizenship question," the ASA continued, "is likely to keep some people from responding to the questionnaire and others from responding truthfully, thereby undermining the accuracy of the data. In addition ..., [w]ith little time left before the 2020 launch, a new question could not be subject to standard rigorous testing, which would further undermine the quality of the data." Id.

41. Similarly, on January 9, 2018, members of the Census Scientific Advisory Committee ("CSAC") wrote to then-Attorney General Jeff Sessions, Secretary Ross, and others, calling inclusion of a citizenship question "a serious mistake which would result in a substantial lowering of the response rate." AR 794. The CSAC members noted that "[a]dding a citizenship question to the main Census questionnaire is almost certain to jeopardize the cooperation of at least some community partners and lead to a lower response rate, hurting the reputation of the Census Bureau." Id. at AR 794-95.

*54142. On January 10, 2018, the Leadership Conference on Civil and Human Rights (the "Leadership Conference") wrote to "urge" Secretary Ross "to reject the Department of Justice's untimely and unnecessary request for a new citizenship question on the 2020 Census, which would threaten a fair and accurate decennial census." AR 798. Adding a citizenship question "would destroy any chance for an accurate count, discard years of careful research, and increase costs significantly." Id. Moreover, the Leadership Conference continued, adding a citizenship question was "unnecessary." Id. at AR 799. "The Justice Department has never needed to add this new question to the decennial census to enforce the Voting Rights Act before, so there is no reason it would need to do so now." Id .

43. On January 26, 2018, Secretary Ross received a letter from six former Directors of the Census Bureau - John Thompson, Robert Groves, Steven Murdock, Kenneth Prewitt, Martha Farnsworth Riche, and Vincent Barabba - expressing concern about the possible addition of a citizenship question. See AR 8555-56. The former Directors said they were "troubled to learn that the Department of Justice has recently asked the Bureau to add a new question on citizenship to the 2020 census." Id. at AR 8555. They were "deeply concerned about the consequence of this possible action and hope[d] that [their] objective observations provide a useful perspective before a final decision is made on this issue." Id.

44. In particular, the former Directors expressed concern that the question had not been appropriately tested. They noted that "[t]here is a great deal of evidence that even small changes in survey question order, wording, and instructions can have significant, and often unexpected, consequences for the rate, quality, and truthfulness of response." Id. at AR 8556. That is why "[t]here is a well-proven multi-year process to suggest and test new questions." Id. at AR 8555. They wrote that they "strongly believe[d] that adding an untested question on citizenship status at this late point in the decennial planning process would put the accuracy of the enumeration and success of the census in all communities at grave risk." Id.

45. On March 19, 2018, Secretary Ross received a letter from the Latino Community Foundation, which "strongly urge[d Secretary Ross] to reject the inclusion of a citizenship question to the 2020 Census." AR 1222. The Foundation explained: "Including a citizenship question to the census will add to an extensive list of concerns that can and will suppress Latino participation. Increased immigration enforcement, anti-immigrant rhetoric in our political discourse, and privacy concerns have already meshed together to create a climate of fear and aversion of the federal government." Id.

46. On March 22, 2018, Secretary Ross received a letter from Ready Nation, a council of "American business leaders," who wrote "to express [its] deep concern about the Department of Justice's request that the Census Bureau include an untested question about citizenship in the 2020 Census questionnaire." AR 3608. The business leaders were concerned because "[t]he decennial Census provides critical data that informs decisionmaking in both the private and public sectors"; they expressed the worry that "[a]dding a new question this late in the decennial Census process could reduce the accuracy" of the census. Id.

47. On March 23, 2018, Secretary Ross received a letter from members of the scientific community, including the Acting President of the Federation of American *542Scientists, the Director of 2020 Census Counts, and the President of the American Political Science Association. See AR 1269-71. The letter stated that the DOJ request "is ill-conceived for a number of reasons. We have more accurate methods for measuring and studying non-citizenship, for example through anonymous surveys. Imposing a citizenship question would lead to a lower participation rate and substantial undercount of certain geographic regions and demographic populations, undermining the scientific integrity of the entire project." Id. at AR 1269.

48. That same day, Secretary Ross spoke with Christine Pierce, Senior Vice President of Data Science for Nielsen, a private survey company. See AR 1276. According to the Commerce Department notes of the conversation, Pierce expressed concern that the addition of the citizenship question "could lead to a lower response rate," which "is very important." Id. Pierce said that "including a question on citizenship could make people less likely to respond, but that there is no data to predict how much lower the response rate might be." Id. Pierce explained that at Nielsen, when the company was considering asking a sensitive question that was expected to depress response rates, the company "conducts a cost-benefit analysis to determine whether it is worth asking the question." Id. She "noted the importance of testing questions." Id. With regard to the federal government's questions, Pierce described that Nielsen once added the ACS questions about birthplace and date of arrival in the United States to one of its surveys. Id. She explained that although the company was "concerned about response rates declining, ... Nielsen did not observe lower response rates to the survey." Id. But, Pierce noted, Nielsen would have offered a cash reward to incentivize participation in that survey. See id.

6. Secretary Ross's March 26, 2018 Memorandum

49. As noted, on March 26, 2018, Secretary Ross issued his memorandum announcing the decision to adopt Alternative D (which he referred as "Option D"), which included adding the citizenship question to the 2020 census. See Ross Memo 1, 4, at AR 1313, 1316. Secretary Ross wrote that "[f]ollowing receipt" of the Gary Letter on December 12, 2017, he had "set out to take a hard look at the request and ensure that [he] considered all facts and data relevant to the question so that [he] could make an informed decision on how to respond." Id. at AR 1313. "To that end," he wrote, the Department of Commerce "immediately initiated a comprehensive review process led by the Census Bureau."Id.

50. Secretary Ross said that his decision "prioritized the goal of obtaining complete and accurate data ." Id. (emphasis in original). He wrote that "Congress has delegated to me the authority to determine which questions should be asked on the decennial census, and I may exercise my discretion to reinstate the citizenship question on the 2020 decennial census, especially based on DOJ's request for improved CVAP data to enforce the VRA." Id. at AR 1314. Secretary Ross did not cite any authority for the proposition that the DOJ's request expanded his discretion to determine the content of the decennial census questionnaire. See id . Nor did Secretary Ross address whether he was required to comply with DOJ's request in the first place. See id.

51. Secretary Ross noted that "collection of citizenship data by the Census [Bureau] has been a long-standing practice." Id . He gave as examples of this "long-standing practice" the fact that a citizenship question had appeared on decennial *543censuses up until 1950; that the 2000 "long form" survey "distributed to one in six people in the U.S.[ ] included a question on citizenship"; and that the ACS (which replaced the "long form sample") had "included a citizenship question since 2005." Id. (internal quotation marks omitted). From this, he concluded that "the citizenship question has been well tested." Id. Secretary Ross did not, however, detail any such testing or address how the testing would apply to a question in 2020 on a census questionnaire distributed to the entire population.

52. Secretary Ross explained that DOJ had stated "that the current data collected under the ACS are insufficient in scope, detail, and certainty to meet its purpose under the VRA." Id. For that reason, DOJ sought "CVAP data for census blocks, block groups, counties, towns, and other locations where potential Section 2 violations are alleged or suspected." Id. Secretary Ross explained that the "Census Bureau ha[d] advised [him] that the census-block-level citizenship data requested by DOJ are not available using the annual ACS, which ... does ask a citizenship question and is the present method used to provide DOJ and the courts with data used to enforce Section 2 of the VRA." Id.

53. Secretary Ross then discussed the four alternatives he had considered in reaching his decision: Alternatives A, B, C, and D (albeit referring to them as "Options" A, B, C, and D). Id. at AR 1314-17.

54. The Ross Memo described Alternative A as rejecting the DOJ request entirely and relying entirely on existing citizenship data. See id. at AR 1314; January 19 Memo, at AR 1279. Secretary Ross rejected this option because, "[u]nder Option A, the 2020 decennial census would not include the question on citizenship that DOJ requested and therefore would not provide DOJ with improved CVAP data." Ross Memo 2, at AR 1314. The existing block-level CVAP data obtained through the ACS, he noted, "has associated margins of error because the ACS is extrapolated based on sample surveys." Id. Thus, Secretary Ross reasoned, "[p]roviding more precise block-level data would require sophisticated statistical modeling," requiring "the Census Bureau ... to deploy a team of experts to develop model-based methods that attempt to better facilitate DOJ's request for more specific data." Id. Secretary Ross's problem with this option was that "the Census Bureau did not assert and could not confirm that such data modeling is possible for census-block-level data with a sufficient degree of accuracy," and, "[r]egardless, DOJ's request is based at least in part on the fact that existing ACS citizenship data-sets lack specificity and completeness," such that "[a]ny future modeling from these incomplete data would only compound that problem." Id. at AR 1314-15. In summary, Secretary Ross wrote that he rejected Alternative A because it "would provide no improved citizenship count, as the existing ACS sampling would still fail to obtain actual , complete number counts, especially for certain lower population areas or voting districts, and there is no guarantee that data could be improved using small-area modeling methods." Id. at AR 1315.

55. Secretary Ross then turned to Alternative B, "which would add a citizenship question to the decennial census." Id. Secretary Ross acknowledged that "[t]he Census Bureau and many stakeholders expressed concern that Option B ... would negatively impact the response rate for non-citizens," which "could reduce the accuracy of the decennial census and increase costs for non-response followup ('NRFU') operations." Id. (emphasis omitted). "However," he continued, "neither the Census Bureau nor the concerned *544stakeholders could document that the response rate would in fact decline materially." Id. Secretary Ross cited three sources for this conclusion. First, he stated that he had "discuss[ed] the question with the national survey agency Nielsen" and that Nielsen had "stated that it had added questions from the ACS on sensitive topics such as place of birth and immigration status to certain short survey forms without any appreciable decrease in response rates." Id. Second, "the former director of the Census Bureau during the last decennial census" said "that, while he wished there were data to answer the [citizenship] question, none existed to his knowledge." Id. Third, "Nielsen's Senior Vice President for Data Science and the former Deputy Director and Chief Operating Officer of the Census Bureau under President George W. Bush also confirmed that, to the best of their knowledge, no empirical data existed on the impact of a citizenship question on responses." Id.

56. Secretary Ross noted that "the Census Bureau attempted to assess the impact that reinstatement of a citizenship question on the decennial census would have on response rates by drawing comparisons to ACS responses," as the Census Bureau had done in the January 19 Memo. Id. ; see January 19 Memo, at AR 1279-80. Secretary Ross wrote that "such comparative analysis was challenging, as response rates generally vary between decennial censuses and other census sample surveys." Ross Memo 3, at AR 1315. For example, the Census Bureau attributed higher response rates on the decennial census to "greater outreach and follow-up associated with the ... decennial census" and to the comparatively short length of the decennial census questionnaire compared to the ACS. Id.

57. Secretary Ross also assessed the empirical data showing that Hispanics were disproportionately likely not to self-respond to citizenship questions. See id. at AR 1315-16. With regard to the ACS, he pointed out that many questions other than the citizenship question also have significant nonresponse rates. Id. at AR 1315. But in citing those other questions, he did not acknowledge any comparative response rates by race or ethnicity, citing only average nonresponse rates. See id. With regard to the decennial census, Secretary Ross acknowledged the Census Bureau's data showing that noncitizen households (compared to citizen households) were disproportionately less likely to self-respond to the 2000 long-form census questionnaire, which included a citizenship question, than to the short-form questionnaire, which did not. See id. at AR 1316. But, Secretary Ross wrote, the Census Bureau "was not able to isolate what percentage of decline was caused by the inclusion of a citizenship question rather than some other aspect of the long form survey." Id. He concluded that "while there is widespread belief among many parties that adding a citizenship question could reduce response rates, the Census Bureau's analysis did not provide definitive, empirical support for that belief." Id.

58. Secretary Ross next evaluated Alternative C, which would use administrative records instead of adding a citizenship question to the decennial census. Id. He acknowledged that the Census Bureau had used administrative record data "since the early 20th century" and that administrative records often yield "more accurate" citizenship data than self-responses do. Id. "However," he wrote, "the Census Bureau is still evolving its use of administrative records, and the Bureau does not yet have a complete administrative records data set for the entire population." Id. He also acknowledged that the Census Bureau was able to match 88.6% of the population "with what the Bureau considers credible *545administrative record data" in the 2010 census. Id. But, he wrote, "[w]hile impressive, this means that more than 10 percent of the American population - some 25 million voting age people - would need to have their citizenship imputed by the Census Bureau. Given the scale of this number, it was imperative that another option be developed to provide a greater level of accuracy than either self-response alone or use of administrative records would presently provide." Id.

59. Secretary Ross explained that he had "asked the Census Bureau to develop" an Alternative D, which "would combine" Alternatives B and C. See id. His "judgment," the Memo announced, was that Alternative D "will provide DOJ with the most complete and accurate CVAP data in response to its request." Id. at AR 1317. Secretary Ross explained:

Asking the citizenship question of 100 percent of the population gives each respondent the opportunity to provide an answer. This may eliminate the need for the Census Bureau to have to impute an answer for millions of people. For the approximately 90 percent of the population who are citizens, this question is no additional imposition. And for the approximately 70 percent of non-citizens who already answer this question accurately on the ACS, the question is no additional imposition since census responses by law may only be used anonymously and for statistical purposes. Finally, placing the question on the decennial census and directing the Census Bureau to determine the best means to compare the decennial census responses with administrative records will permit the Census Bureau to determine the inaccurate response rate for citizens and non-citizens alike using the entire population. This will enable the Census Bureau to establish, to the best of its ability, the accurate ratio of citizen to non-citizen responses to impute for that small percentage of cases where it is necessary to do so.

Id.

60. Secretary Ross addressed the possible effect on self-response rates of the citizenship question as set forth in Alternative D. See id. at AR 1319. He opined that "even if" addition of a citizenship question had "some impact on responses, the value of more complete and accurate data derived from surveying the entire population outweighs such concerns. Completing and returning decennial census questionnaires is required by Federal law, those responses are protected by law, and inclusion of a citizenship question on the 2020 decennial census will provide more complete information for those who respond."Id. Secretary Ross then stated, without reference to any evidence or to the Census Bureau's conclusion that adding a citizen question would produce "substantially less accurate citizenship status data than are available from administrative sources," January 19 Memo, at AR 1277, that "[t]he citizenship data provided to DOJ will be more accurate with the question than without it," Ross Memo 7, at AR 1319. He wrote that this "accura[cy]" was "of greater importance than any adverse effect that may result from people violating their legal duty to respond." Id.

61. Secretary Ross concluded: "I have determined that reinstatement of a citizenship question on the 2020 decennial census is necessary to provide complete and accurate data in response to the DOJ request." Id. at AR 1320. He also announced his decision to place the question "last on the decennial census form" to "minimize any impact on decennial census response rates." Id.

7. Secretary Ross's Testimony Before Congress

62. As the foregoing makes clear, the chronology of events in the initial Administrative *546Record produced on June 8, 2018, largely conformed to the chronology in the Ross Memo. According to the Ross Memo, the decision to add a citizenship question to the 2020 census began with the December 12, 2017 request from Arthur Gary, a career official at DOJ. See Ross Memo 1, at AR 1313. "Following receipt" of the Gary Letter, Secretary Ross claimed, he had "set out to take a hard look at the request." Id . The Memo did not mention any earlier discussions and efforts to propose addition of a citizenship question or any role in those discussions by White House personnel, political appointees at DOJ, or political appointees at the Commerce Department. See id. at AR 1313-14.

63. In sworn testimony before Congress around the same time, Secretary Ross repeated that the decision to add a citizenship question began with the Gary Letter and denied White House involvement in the decision and discussions leading to the decision.

64. Before the House Appropriations Committee on March 20, 2018, for example, Representative José Serrano asked Secretary Ross whether "the President or anyone else in the White House [had] directed [him] to add this or a similar question to the 2020 census." Hearings Before Subcomm. on Commerce, Justice, Science, and Related Agencies of the H. Comm. on Appropriations , 115th Cong. 15 (2018) (admitted as an audio file at PX-491). Secretary Ross responded that the Department of Commerce was "responding solely to Department of Justice's request." Id. (emphasis added). Later in the same hearing, Representative Grace Meng asked Secretary Ross whether "the President or anyone in the White House discussed with you or anyone on your team about adding this citizenship question." Id. at 38 (admitted as an audio file at PX-493). Secretary Ross answered: "I am not aware of any such." Id .

65. Secretary Ross testified similarly before the House Ways and Means Committee on March 22, 2018. See Hearing with Commerce Secretary Ross: Hearing Before the H. Comm. on Ways and Means , 115th Cong. 1 (2018) (admitted as PX-480). Most relevant here, Representative Judy Chu asked if Secretary Ross could tell her "whether the Department of Commerce plans to include the citizenship question in the 2020 Census." Id. at 51. Secretary Ross responded that the "Department of Justice, as you know, initiated the request for inclusion of the citizenship question" to the decennial census. Id. (emphasis added).

66. Finally, before the Senate Subcommittee on Commerce, Justice, Science, and Related Agencies on May 10, 2018, Secretary Ross testified again that DOJ had initiated the request. See Hearing on the F.Y. 2019 Funding Request for the Commerce Dep't Before the S. Appropriations Subcomm. on Commerce, Justice, and Science and Related Agencies , 2018 WL 2179074 (May 10, 2018). Senator Patrick Leahy questioned whether a citizenship question was actually "necessary to enforce the Voting Rights Act." Id. He asked Secretary Ross: "[W]hy this sudden interest in that when the department that's supposed to enforce violations doesn't see any problems?" Id . Secretary Ross responded: "Well, the Justice Department is the one who made the request of us." Id .

67. In a brief filed with the Supreme Court in December 2018, Defendants argue that "[v]iewed in context," these statements should not be understood to imply that the Department of Commerce had not previously considered the issue or spoken with others in the Administration about it.

*547Brief for the Petitioners at 27, Dep't of Commerce v. U.S. Dist. Ct. for S.D.N.Y. (Dec. 17, 2018) (No. 18-557), 2018 WL 6650094, at *27. Instead, they argue that Secretary Ross's response to Representative Serrano should be understood to mean that "no outside political parties or campaigns had made a request to which the Department of Commerce was responding"; that his statement to Representative Meng was in reference to an email purportedly sent by the Trump Reelection Campaign and thus only about "whether any political actors in the White House had made a formal request" about the citizenship question; that his response to Representative Chu pertained only to the "formal process" that began with the Gary Letter; and that his assertion to Senator Leahy was meant only to "rebut[ ]" Senator Leahy's suggestion that DOJ did not see a problem with current VRA enforcement. Id. at 27-31 (emphasis omitted).

68. Defendants' post hoc interpretations of Secretary Ross's sworn statements to Congress are unconvincing. Viewed individually, even in context, none of the statements are limited in the ways Defendants suggest. And viewed together, the statements afford only one conclusion: Secretary Ross intended to convey the impression that the Gary Letter - and the Gary Letter alone - prompted consideration of whether to add a citizenship question to the census; that neither he nor anyone else at the Commerce Department prompted DOJ's request; and that he had not discussed the matter with White House officials before 2018. Moreover, nothing in Secretary Ross's March 26, 2018 Memorandum, in the rest of the Administrative Record, or in the relevant statutes and regulations supports the purported distinction between an "informal" and "formal" process.17

B. The Supplemental Administrative Record and the Trial Record

69. Secretary Ross's first version of events, set forth in the initial Administrative Record, the Ross Memo, and his congressional testimony, was materially inaccurate.

70. The first concrete sign of the inaccuracy came on June 21, 2018, when - "to provide further background and context regarding" Secretary Ross's decision - Defendants added a one-page "Supplemental Memorandum" signed by Secretary Ross himself, to the Administrative Record. See Docket No. 189.18 In the Supplemental *548Memorandum, Secretary Ross admitted that "[s]oon after [his] appointment as Secretary of Commerce," he had begun considering "whether to reinstate a citizenship question." AR 1321 ("June 21 Supplemental Memo"). He also acknowledged that "other senior Administration officials had previously raised" the issue, but he did not identify the officials by name. Id . He continued: "My staff and I thought reinstating a citizenship question could be warranted, and we had various discussions with other governmental officials about reinstating a citizenship question to the Census." Id. He then disclosed that, "[a]s part of that deliberative process," he and his staff had "inquired whether the Department of Justice ... would support, and if so would request , inclusion of a citizenship question as consistent with and useful for enforcement of" the VRA. Id. (emphasis added).

71. After receiving Secretary Ross's Supplemental Memorandum, the Court ordered Defendants to complete the Administrative Record and authorized discovery beyond the Administrative Record. See Docket No. 199; see also July 3rd Tr. 76-89.19

72. The evidence disclosed as a result reveals a very different set of events from the one described in the initial Administrative Record, the Ross Memo, and Secretary Ross's congressional testimony. In particular, as outlined in depth below, the evidence shows that shortly after his confirmation as Secretary of Commerce, Secretary Ross discussed the addition of the citizenship question with then-White House advisor Steve Bannon, among others; that Secretary Ross wanted to add the question to the 2020 census prior to, and independent of, DOJ's December 12, 2017 request; that the Secretary and his aides pursued that goal vigorously for almost a year, with no apparent interest in promoting more robust enforcement of the VRA; that, believing they needed another agency to request and justify a need for the question, Secretary Ross and his aides worked hard to generate such a request for the citizenship question from DOJ; that these efforts included a direct intervention by Secretary Ross with Attorney General Sessions; and that these efforts ultimately *549succeeded, resulting in DOJ's request for a citizenship question. The evidence also reveals that DOJ deliberately (and unusually) did not explore whether there was a way to obtain the data it purportedly needed that would not involve a citizenship question on the census. The Court now turns to this more complete story of Secretary Ross's decision.

1. Secretary Ross's Early Interest in Adding the Citizenship Question

73. The Senate confirmed Secretary Ross as Secretary of Commerce on February 27, 2017. See 163 CONG. REC . S1421, S1455 (2017). Two days later, on March 1, 2017, the Census Bureau briefed Secretary Ross on the census and the upcoming deadline to notify Congress about the proposed subjects for the census questionnaire. See AR 1410, 3685-86; PX-193 ("Ross Calendar"), at 1; Docket Nos. 510-2, 510-3 (together, "Langdon Dep.") at 81, 93-98; see also 13 U.S.C. § 141(f)(3).

74. At some point between February 27 and March 10, 2017, Secretary Ross asked his Deputy Chief of Staff and Director of Policy, Earl Comstock, why there was no citizenship question on the census. See Docket No. 490-2 ("Comstock Dep.") at 55. Comstock responded that he did not know, but would "check." Id. On March 10, 2017, Comstock sent Secretary Ross an email with the subject line: "Your Question on the Census." AR 2521. The email reported that the Census Bureau's webpage on apportionment was "explicit" that "all people (citizens and noncitizens) with a usual residence in the 50 states are to be included in the census and thus in the apportionment counts." Id . The email also included the text of a Wall Street Journal article titled "The Pitfalls of Counting Illegal Immigrants," which, Comstock noted, "confirms that neither the 2000 nor the 2010 Census asked about citizenship." Id.

75. Around this same time, Secretary Ross's interest in adding a citizenship question to the census first surfaced. Comstock, for example, first heard "about the notion of adding a question about citizenship to the decennial census" from the Secretary himself, "shortly after the confirmation." Id. at 54. In fact, some evidence suggests that Secretary Ross went even further in these early weeks and had actually decided to add the citizenship question already. According to Comstock, for example, Secretary Ross actually made a "request" to add the citizenship question "sometime in the spring" - "[p]otentially" as early as March 10, 2017 (when Comstock had emailed him the Wall Street Journal article). Id. at 146.

76. Although Secretary Ross acknowledges speaking with various "senior Administration officials" and "other governmental officials" about adding a citizenship question to the census around this time, AR 1321, the record is largely (and somewhat surprisingly) void of details regarding when these conversations occurred and with whom. But it does reflect that Secretary Ross discussed the topic with at least three outside officials. First, Secretary Ross discussed the topic with Attorney General Sessions "in the Spring of 2017 and at subsequent times." See Docket No. 379-1 ("Defs.' Second Supp. Interrog."), at 2-3 (admitted as PX-302). Second, on or about April 5, 2017, Secretary Ross spoke with White House advisor Steve Bannon, who asked "if he would be willing to speak to Kansas Secretary of State Kris Kobach about Secretary Kobach's ideas about a possible citizenship question on the decennial census." Id. at 3; AR 763-64, 2561. Third, complying with Bannon's request, Secretary Ross spoke with Kobach (who also served as Vice Chair of the since aborted Presidential Commission on Election Integrity). See AR 763-64, 2561; Defs.'

*550Second Supp. Interrog. at 2-3; Docket Nos. 509-2, 509-3 (together, "Teramoto Dep.") at 38-47. During that discussion, Secretary Ross and Kobach discussed the potential effect on "congressional apportionment" of adding "one simple question" to the census. AR 763-64.

77. After these conversations, Secretary Ross and his staff began to take action on the citizenship question, in part by contacting Mark Neuman, who was not then a government official but had served as the point person on census-related issues for the Trump Administration's transition team. Teramoto Dep. 126-27. On April 11, 2017, Neuman emailed Comstock a link to the Supreme Court's decision in League of United Latin Am. Citizens v. Perry , 548 U.S. 399, 126 S.Ct. 2594, 165 L.Ed.2d 609 (2006) (" LULAC "), which considered CVAP data in assessing claims under Section 2 of the VRA. See PX-188 (AR); see also Comstock Dep. 155-56. On April 13, 2017, Comstock asked Neuman by email when the Census Bureau would need to "notify Congress" regarding census questions. AR 3709. Neuman responded the next day, informing Comstock that the notification deadline for census topics had already passed, but there would "be another opportunity next year" when the report of specific questions was due to Congress. AR 3709.

78. Secretary Ross soon began to express frustration with his staff's lack of progress on the citizenship question issue. On April 20, 2017, for example, he emailed Comstock, copying Wendy Teramoto, who was then his Senior Advisor and Chief of Staff. See AR 3694; Teramoto Dep. 78.20 In the email, he noted that then-Director of the Census Bureau John Thompson was scheduled to meet with the Census National Advisory Committee on Racial, Ethnic and Other Populations on April 29, 2017, and he noted: "We must get our issue resolved before this!" AR 3694 (emphasis in original); see Comstock Dep. 137-41.

79. On May 2, 2017, Secretary Ross expressed even greater frustration. He emailed Comstock that he was "mystified why nothing ha[s] been done in response to [his] months old request that we include the citizenship question." AR 3710 (emphasis added).

80. A few hours later, Comstock responded. "On the citizenship question," he declared, "we will get that in place." Id. ; PX-298(R), at RFA 63;21 see Comstock Dep. 151-52. He explained that the specific questions on the census questionnaire were not due to Congress until March 2018. See AR 3710. In the meantime, Comstock wrote, "[w]e need to work with Justice to get them to request that citizenship be added back as a census question, and we have the court cases to illustrate that DoJ has a legitimate need for the question to be included." Id . Comstock promised to "arrange a meeting with DoJ staff this week to discuss." Id.

2. Comstock's Search for a Rationale and an Agency to Request the Question

81. By May 2, 2017, Comstock had come to believe that the Commerce Department *551would need another agency to request addition of the citizenship question on the census because OMB and the Paperwork Reduction Act, 44 U.S.C. §§ 3501 et seq. , required the Commerce Department to "justify" why a citizenship question was "need[ed]." Comstock Dep. 153-54. Comstock acknowledged that simply "say[ing] the Secretary wanted" the question added would not "clear [the] legal thresholds." Id. at 154.

82. With this understanding, Comstock set out to find a "legal rationale" to support the Secretary's request to add a citizenship question, id. at 266, and to "find an agency that would have a reason" to do so, id. at 181. Comstock testified that he viewed it as his job to "help [the Secretary] find the best rationale" for adding the question, because "[t]hat's what a policy person does." Id. at 267. In his view, he did not "need to know what" the Secretary's actual "rationale might be, because it may or may not be one that is ... legally-valid." Id.

83. On May 4, 2017, two days after promising Secretary Ross that he would "get [the citizenship question] in place," Comstock emailed Eric Branstad, the Senior White House Advisor at the Department of Commerce, asking him to identify the "best counterpart ... at DOJ" to speak with "[r]egarding [the] Census." AR 3701; see also AR 12755; AR 2458 (same as AR 12755 but with more redactions); AR 12756 (similar to AR 12755). Branstad advised Comstock to contact Mary Blanche Hankey, who had previously served as legislative counsel to then-Senator Jeff Sessions and, at the time, was the White House liaison at DOJ. See AR 3701, 12755.

84. Later that day, Comstock emailed Hankey and asked to set up a meeting. AR 2462; see also AR 12755; PX-298(R), at RFA 68. At some point that month, Comstock and Hankey spoke in person; "[a] few days later," Hankey "directed [Comstock] to James McHenry in the Department of Justice." AR 12755. McHenry was the Director of DOJ's Executive Office for Immigration Review; he had no responsibility for enforcement of the VRA. See Attorney General Sessions Announces Appointment of James McHenry As Director of the Executive Office for Immigration Review, Department of Justice (Jan. 10, 2018), https://www.justice.gov/opa/pr/attorney-general-sessions-announces-appointment-james-mchenry-director-executive-office; PX-298(R), at RFA 71; Docket No. 491-2 ("Gore Dep."), at 65.

85. Comstock and McHenry "spoke several times ... by phone." AR 12755. After these calls and "considering the matter further," McHenry told Comstock that "Justice staff did not want to raise the [citizenship] question given the difficulties Justice was encountering in the press at the time (the whole Comey matter)." Id .22 McHenry referred Comstock instead to Gene Hamilton at the Department of Homeland Security ("DHS"). Id. Comstock and Hamilton held "several phone calls to discuss the matter," but Hamilton "relayed that after discussion DHS really felt that it was best handled by Department of Justice." Id. Faced with these rejections by DOJ and DHS, Comstock turned to James Uthmeier, a lawyer at the Commerce Department. Id. He asked Uthmeier "to look into the legal issues and how Commerce *552could add the question to the Census itself." Id.

86. On May 24, 2017, Secretary Ross met "all afternoon" with various aides, including David Langdon, a Policy Advisor who reported to Comstock. AR 12542; see also AR 3702-04 (same as AR 12541-43 but with more redactions). During the meeting, Secretary Ross "seemed ... puzzled why citizenship is not included in [the] 2020" census. AR 12541. At about 11 p.m. that night, Langdon emailed Lisa Blumerman, Acting Associate Director of the 2020 Decennial Census, asking her to respond immediately - "[i]deally this evening" - to his inquiry about a citizenship question. Id. ; see also Langdon Dep. 172-74. Langdon reported to Comstock that he made that request. PX-543 (AR).

3. Secretary Ross and His Aides Persist in Their Efforts

87. Throughout July and August 2017, Secretary Ross and his staff continued to work internally, and with Kobach, to arrange for the addition of the citizenship question.

88. On July 14, 2017, Kobach emailed Secretary Ross to follow up on their April telephone conversation. See AR 763-64. Kobach wrote that the lack of a citizenship question on the census "impairs the federal government's ability to do a number of things accurately," and "also leads to the problem that aliens who do not actually 'reside' in the United States are still counted for congressional apportionment purposes." Id. at AR 764; PX-298(R), at RFA 81-82. Kobach stated that it was "essential that one simple question be added to the upcoming 2020 census," urging, in particular, a "slight variant" of the citizenship question that appears on the ACS. AR 763-64, at AR 764. Kobach did not mention the VRA or any rationale tied to VRA enforcement. Id .

89. On July 21, 2017, Kobach called Teramoto. See id. at AR 763. He also forwarded her his July 14, 2017 email to Secretary Ross. See id. In a note above the forwarded email, Kobach wrote that he had "spoken" to Secretary Ross about the addition of citizenship question to the census "at the direction of Steve Bannon." Id. ; see also PX-298(R), at RFA 83. He asked "to schedule a short call." AR 763. In response to this email, Teramoto arranged a call between Kobach and Secretary Ross. See id . Teramoto would later testify that she had "no recollection of ever speaking" with Kobach. Teramoto Dep. 40-45. She also testified that she had "no idea" who Kobach was, id. , even though the email he forwarded to her began with the line: "Kansas Secretary of State Kris Kobach here." AR 764.23 On or about July 25, 2017, Secretary Ross spoke with Kobach about the addition of a citizenship question to the decennial census. See id. ; Ross Calendar. at 8, 40; PX-298(R), at RFA 84.

90. On August 8, 2017, Representative Mark Meadows and Secretary Ross spoke by telephone. Ross Calendar at 9. Later that day, Secretary Ross emailed Comstock to ask "where" DOJ was "in their analysis" of whether to request the addition of a citizenship question. See AR 4004; PX-298(R), at RFA 91; see also Comstock Dep. 213. Secretary Ross advised: "If [DOJ] still have not come to a conclusion please let me know your contact person and I will call the AG." AR 4004; PX-298(R), *553at RFA 92; Comstock Dep. 214. Comstock immediately responded to Secretary Ross, writing that he would "be back shortly with an update." AR 4004; PX-298(R), at RFA 93.

91. The next day, August 9, 2017, Comstock responded again by email to Secretary Ross about their internal analysis of the citizenship question. See AR 12476; see also AR 3984 (same as AR 12476 but with more redactions). He wrote: "[W]e are preparing a memo and full briefing for you on the citizenship question. The memo will be ready by Friday." AR 12476. Critically, Comstock cautioned: "Since this issue will go to the Supreme Court we need to be diligent in preparing the administrative record." Id. Secretary Ross responded that he "would like to be briefed on Friday by phone" and added that "we should be very careful, about everything, whether or not it is likely to end up in the SC." Id.

92. On August 11, 2017, Comstock and Uthmeier exchanged edits on briefing materials regarding the citizenship question for Secretary Ross. In one email, Uthmeier shared "recommendations on execution." PX-607 (AR), at 2; AR 11343-45 (redacted version). Uthmeier stated that "our hook" was "[u]ltimately, we do not make decisions on how the [citizenship] data will be used for apportionment, that is for Congress (or possibly the President) to decide." PX-607 (AR), at 2. Later the same day, Comstock emailed Secretary Ross and Teramoto a memorandum prepared by Uthmeier regarding the addition of a citizenship question to the census. See AR 2461; see also AR 11362. (The Memorandum itself was withheld by Defendants - with the Court's blessing, see Docket No. 361 - on the basis of attorney-client privilege and, thus, is not part of the record.)

93. On August 21, 2017, senior Commerce Department personnel met regarding the citizenship question. See AR 2461. Attendees included Teramoto; Comstock; Peter Davidson, the newly appointed Commerce Department General Counsel, see 163 CONG. REC . S4781, S4897 (2017); and Under Secretary Kelley, who oversaw the operations of the Census Bureau, see id . See AR 2461; Docket No. 493-2 ("Kelley Dep."), at 25. During their respective depositions, however, Comstock, Teramoto, and Under Secretary Kelley denied having any recollection of the August 21, 2017 meeting. See Comstock Dep. 221; Teramoto Dep. 54-58; Kelley Dep. 91-92.

94. On September 1, 2017, Secretary Ross complained to Comstock and Teramoto that he had "received no update" on "the issue of the census question." AR 2424; see also AR 4002-03, at AR 4002. Comstock responded: "Understood. Wendy and I are working on it." AR 4002-03, at AR 4002.

95. On September 6, 2017, Secretary Ross met with various aides, including Under Secretary Kelley, Teramoto, Comstock, Davidson, and Uthmeier, to discuss addition of the citizenship question. See AR 1411-12; AR 1996-97; AR 2426-28; Ross Calendar 11 ("Staff Briefing: Census Legal Question"); see also AR 1998-99 (same email chain as AR 1996-97); AR 2429-30 (same email chain as AR 2426-28). Uthmeier prepared a briefing book for the meeting, which he gave to at least Under Secretary Kelley. See AR 1996-97, at AR 1996; Docket No. 253 ("Uthmeier Decl."), ¶ 3. The briefing book is not part of the record, however, apparently because none of the participants in the meeting retained a copy. See Pls.' Proposed Findings ¶ 383. At their depositions, Under Secretary Kelley, Comstock, and Teramoto denied having any recollection of the meeting. See Comstock Dep. 221; Teramoto Dep. 58-61; Kelley Dep. 105-07.

96. The day after the meeting with Secretary Ross, Comstock emailed Uthmeier *554and Davidson that Secretary Ross "would like an update on progress since the discussion yesterday regarding the citizenship question." AR 2034; see also AR 2395-96; AR 2459-60. Later that day, Davidson wrote to Comstock, Uthmeier, and Teramoto expressing "concern[ ] about" directly contacting Kobach - whom Secretary Ross had mentioned in the September 6, 2017 meeting. PX-614 (AR). Instead, Davidson recommended contacting a "trusted" advisor, such as Neuman, "before we do anything externally." Id.

97. Consistent with that recommendation, Uthmeier sent Neuman an email on September 8, 2017, with the subject line "Questions re Census," and asking if Neuman had a "few minutes" that morning "to discuss." AR 2051. That same day, Comstock sent Secretary Ross a memorandum reporting on his - as yet unsuccessful - efforts to find an agency that would request addition of a citizenship question to the 2020 census. See AR 12755; PX-298(R) at RFA 96. The memorandum summarized Comstock's prior discussions with Hankey and McHenry of DOJ, and with Hamilton of DHS, and noted that none had expressed interest in requesting the addition of the citizenship question on the census. See AR 12755.

4. Secretary Ross's Intervention with the Attorney General

98. By sometime in late summer 2017, Secretary Ross was plainly out of patience with Comstock's failed efforts to get DOJ to request the citizenship question and decided to take matters into his own hands by contacting Attorney General Sessions directly. The precise date of his first communication on the census topic with the Attorney General during that period is unclear. See AR 1321; Gore Dep. 83-84; see also Defs.' Second Supp. Interrog. 2-3. But around Labor Day, the Attorney General spoke then-Acting Assistant Attorney General for Civil Rights John Gore ("AAAG Gore") about requesting the addition of a citizenship question. Gore Dep. 83. AAAG Gore learned that Secretary Ross had "initiated" an earlier discussion with Attorney General Sessions about a citizenship question. Id. at 83-84.

99. Until September 13, 2017, the conversations between the Commerce Department and DOJ about the citizenship question had been "initiated by the Department of Commerce." Gore Dep. 67-68, 91-98. But on that date, AAAG Gore initiated contact with Teramoto. He sent Teramoto an email introducing himself and asking "to talk about a DOJ-DOC" issue, referring to the addition of a citizenship question to the 2020 census. AR 2628-29, at AR 2629; AR 2634-35 (same email chain); Gore Dep. 95-97. And for the next couple months, AAAG Gore served as the primary contact at DOJ about the citizenship question issue. Gore Dep. 91-92, 94-95.

100. A few days later, on or about September 16, 2017 (a Saturday), AAAG Gore and Teramoto spoke by telephone. See AR 2628-29, at AR 2628; AR 2639. Later that day, AAAG Gore put Teramoto in touch with Danielle Cutrona, an aide to Attorney General Sessions. See AR 2639. In his email introducing them, AAAG Gore explained that "Danielle is the person to connect with about the issue we discussed earlier this afternoon," namely the citizenship question. Id .; AR 2651-52; AR 2653-54; Gore Dep. 102-03.

101. Teramoto asked Cutrona to "let [her] know when the AG is available to speak to Secretary Ross." AR 2639. In response, Cutrona sent Teramoto Attorney General Sessions' cellphone number and stated: "From what John [Gore] told me, it sounds like we can do whatever you all need us to do and the delay was due to a *555miscommunication. The AG is eager to assist." AR 2651; Gore Dep. 105-06.

102. On September 18, 2017, Secretary Ross spoke again to Attorney General Sessions about adding a citizenship question to the census. See AR 2528; AR 2636; Gore Dep. 111-12. The next day, on September 19, 2017, Secretary Ross sent an email with the subject "Census" to Davidson. AR 2528. The email said: "Wendy [Teramoto] and I spoke with the AG yesterday. Please follow up so we can resolve this issue today." Id .

5. AAAG Gore Ghostwrites the DOJ Letter

103. Over the next three months, relying heavily on the VRA rationale first proposed by the Department of Commerce, political appointees in DOJ - led by AAAG Gore - drafted the letter requesting addition of the citizenship question on the decennial census.

104. Notably, in drafting the letter, AAAG Gore relied not only on the Commerce Department's proposed rationale, but also on its work product and its advisors. For example, he spoke with Uthmeier, the Commerce Department lawyer who had drafted the August 11, 2017 legal memorandum on the issue for Secretary Ross. See Gore Dep. 117-19. After they spoke, AAAG Gore received a copy of the memorandum and a handwritten note from Uthmeier. See id. ; see also AR 2461 (email referencing August 11 memo). At his deposition, AAAG Gore stated that "[t]he note contained information regarding [the citizenship question] issue that was considered by the Department of Justice in drafting its request," that is, the December 12, 2017 Gary Letter. Id. 123-24. AAAG Gore acknowledged, however, that Uthmeier had no experience with, or responsibility for, enforcement of the VRA. See id. at 117-18.

105. AAAG Gore also communicated directly with Neuman, who was advising Secretary Ross and his aides on the issue and who appears to have been the first to float the VRA rationale for adding the question. See Gore Dep. 437-38; see also PX-188 (AR); Comstock Dep. 155-56. (Neuman, in turn, kept the Commerce Department abreast of his dealings with DOJ. For example, on Sunday, October 8, 2017, Secretary Ross emailed Davidson with the subject line "Letter from DoJ," asking "what is its status?" AR 2482. Davidson responded: "I'm on the phone with Mark Neuman right now ... he is giving me a readout of his meeting last week." Id .) AAAG Gore knew that Neuman "was advising the Department of Commerce and the Census Bureau with respect to this issue" as well. Gore Dep. 437-38.

106. By November 1, 2017, AAAG Gore had completed a draft of what would become the Gary Letter. See Gore Dep. 126-27. He solicited feedback on the draft from only a few people in DOJ. AAAG Gore emailed the draft letter to Chris Herren, Chief of DOJ's Voting Section, asking for Herren's input. Gore Dep. 126-27. AAAG Gore knew that Herren was a career DOJ official. See Gore Dep. 151-53. AAAG Gore also copied Ben Aguiñaga on his email, and authorized Aguiñaga to forward it to Bethany Pickett. See Gore Dep. 133. AAAG Gore knew that Aguiñaga and Pickett were both political appointees. See id. AAAG Gore also knew that both Aguiñaga and Pickett had recently graduated from law school and that neither had any experience as counsel in VRA cases or in assessing the reliability of CVAP data used in VRA litigation. See id. at 134-35.

107. Herren, Aguiñaga, and Pickett provided substantive feedback on the initial draft of the letter. See id. at 136-37. AAAG Gore also received edits on a "near-final" version of the draft letter from Rachael *556Tucker, then counsel in the front office in the Office of the Attorney General, and Robert Troester, then Associate Deputy Attorney General. See id. at 139-42. Like Aguiñaga and Pickett, neither Trucker nor Troester had any experience as counsel in VRA cases or in assessing the reliability of CVAP data used in VRA litigation. See id. at 140.

108. Tucker's and Troester's edits were the last substantive edits made to the letter before it was sent. See id. at 142, 146. AAAG Gore did not recall receiving any input or edits from career DOJ Civil Rights Division staff other than the first round of edits from Herren. See Gore Dep. 152-53.

109. On or about November 26, 2017, Secretary Ross spoke with President Trump. PX-298(R), at RFA 103. The next evening, Secretary Ross sent Davidson an email with the subject "Census Questions." AR 11193. The email said that the Census Bureau "is about to begin translating the questions into multiple languages and has let [sic] the printing contract. We are out of time. Please set up a call for me tomorrow with whoever is the responsible person at Justice. We must have this resolved." Id. ; PX-298(R), at RFA 105. AAAG Gore called Davidson that afternoon, but the record does not reflect whether they spoke. See AR 2496.

110. Ultimately, Attorney General Sessions made the decision that DOJ would send the letter to request that the Census Bureau add a citizenship question to the census. See Gore Dep. 442. The final authorization to AAAG Gore to send the letter came from Tucker or Troester on behalf of the Attorney General. See id. at 158-60.

111. Although AAAG Gore - a political appointee - was the principal drafter of the letter, he did not sign or send it; instead, those tasks fell to Arthur Gary, a career DOJ official. On December 8, 2017, AAAG Gore emailed Gary a copy of the letter "with leadership's final changes." See id. at 145. He wrote that "[w]ith these changes, we are authorized to send. Sending on Monday is fine." Id. at 146-47. On Tuesday, December 12, 2017, Gary sent the final version of the letter to Dr. Jarmin. AR 663-65; see also AR 5489-91; Gore Dep. 155.

112. The Gary Letter was the first time that DOJ communicated to the Census Bureau that its existing CVAP data was not ideal for VRA enforcement purposes. See Tr. 996. Dr. Abowd testified at trial that "prior to December 2017 ..., the Census Bureau had never heard from the Department of Justice that existing CVAP data ... was not ideal for purpose of DOJ's VRA enforcement work." Id. AAAG Gore understood that before the Gary Letter was sent, DOJ had not reached out to the Department of Commerce to initiate a conversation "for the purposes of obtaining better data to enforce the Voting Rights Act." Gore Dep. 67-68. He was also aware that DOJ "staff did not want to raise the [citizenship] question" in the fall of 2017. Id. at 68-69.

113. AAAG Gore, the primary drafter of the DOJ letter requesting improved data, admitted that he believes "that CVAP data collected through the census questionnaire is not necessary for DOJ's VRA enforcement efforts." Id. at 300. AAAG Gore also testified that he had "no understanding of what the Census Bureau is going to do or what data it's going to provide [DOJ] in the future related to this request," id. at 215-16; that he did not "understand ... any margin of error" associated with the data the Census Bureau will obtain through the citizenship question on the census, id. at 224-25; and that he did not "know whether or not CVAP data produced from responses to the citizenship *557question ... will, in fact, be more precise than the CVAP data on which the DOJ is currently relying for purposes of VRA enforcement," id. at 232-33. AAAG Gore testified that he is not aware of any communications between DOJ and the Census Bureau on these subjects. Id. at 228, 233-34.

114. In short, although the letter AAAG Gore drafted states that the "decennial census questionnaire is the most appropriate vehicle" for collecting "reliable" CVAP data for purposes of enforcing the VRA, Gary Letter at AR 663, AAAG Gore admitted that he did not know whether citizenship data obtained through the census would in fact be "more precise than the CVAP data on which DOJ is currently relying for purposes of VRA enforcement," Gore Dep. 233.

6. The Attorney General Forbids DOJ to Meet with the Census Bureau

115. Throughout December 2017 and January 2018, Census Bureau staff sought to meet with DOJ officials to better understand their request and to discuss other ways to satisfy DOJ's interest in more granular CVAP data. See AR 3289; AR 8651; Docket No. 511-2 ("Jarmin Dep.") at 64. The DOJ rebuffed these attempts.

116. On December 22, 2017, for example, Dr. Jarmin emailed Gary that "the best way to provide PL94 block-level data with citizen voting population by race and ethnicity would be through utilizing a linked file of administrative and survey data the Census Bureau already possesses. This would result in higher quality data produced at a lower cost." AR 3289; see also PX-297, at RFA 184; Tr. 961-62. Dr. Jarmin suggested a "meeting of Census and DOJ technical experts to discuss the details of this proposal." AR 3289.

117. Dr. Jarmin repeatedly followed up with Gary. On January 2, 2018, Dr. Jarmin sent Gary a follow-up email requesting a meeting the following week. See AR 5490. Gary, in turn, informed AAAG Gore that Census Bureau officials were attempting to arrange a meeting between the Census Bureau and DOJ. See Gore Dep. 262-63. AAAG Gore also learned from Gary that the Census Bureau had an alternative means for providing the DOJ with block-level CVAP data. See id. at 265-66. AAAG Gore told Gary that he "would think about the issue and discuss it further with others." Id. at 264. AAAG Gore did not ask Gary to get more information about the specifics of the Census Bureau's alternative proposal. See id. at 268.

118. AAAG Gore then discussed the matter with several DOJ officials, including Attorney General Sessions at an in-person meeting. See id. at 265, 268-69. Attorney General Sessions decided "not to pursue the Census Bureau's alternative proposal." Id. at 271-72. To AAAG Gore's knowledge, the reasons for the Attorney General's decision not to pursue the alternatives were not memorialized anywhere. Id. at 272. To this date, Defendants have not identified any reason for DOJ's decision not to meet with the Census Bureau.

119. DOJ eventually "communicated that it did not want to meet with the Census Bureau to discuss alternative sources of block-level CVAP data other than a citizenship question on the decennial census questionnaire." PX-297, at RFA 200. On February 6, 2018, almost two months after first suggesting a technical meeting to DOJ, Dr. Jarmin reported to the Census Bureau and Commerce staff that DOJ did not want to meet. See AR 3460; AR 9074. He wrote that he had "spoken with DOJ leadership. They believe the letter requesting citizenship be added to the 2020 Census fully describes their *558request. They do not want to meet." AR 3460; AR 9074; Docket Nos. 502-2, 502-4 (together, "Census Bureau 30(b)(6) Dep."), at 98.24

120. Thus, no meeting between the Census Bureau's and DOJ's technical experts took place before Secretary Ross issued his March 26, 2018 Memorandum announcing his decision to add the citizenship question. See Census Bureau 30(b)(6) Dep. 96; Gore Dep. 259; PX-297, at RFA 170, 195, 196.

121. DOJ officials' refusal to meet with the Census Bureau to discuss their request for data was highly "unusual." Census Bureau 30(b)(6) Dep. 98-99. It is standard operating procedure for the Census Bureau to hold a technical meeting with the agency requesting additional data to discuss the best way to deliver usable data for a particular use. See Tr. 1248; see also Thompson Decl. ¶ 60. As Dr. Abowd testified, when "an agency has requested a statistical product that cannot be produced with current public estimates, we would normally expect to meet with that agency to determine ... the use case, the application, what they wanted to do, and why they felt that our current products did not serve that need. That would be normal." Tr. 1248. And as former Census Bureau Director Thompson explained, input from subject matter experts - usually consisting of "staff from both the Census Bureau and the requesting agency" - is "essential to the development of a new question" for a survey. Thompson Decl. ¶ 60. That is because "[t]hese experts help ensure that the Census Bureau has a clear understanding of the desired uses of the new data so that the new question can be worded to achieve the desired outcome." Id. ; see also Habermann Aff. ¶ 29 ("[A meeting between the Census Bureau and the requesting agency] allows the technical experts to better understand how the Census Bureau can meet the needs of the proposers. It also allows for a discussion of alternative ways of meeting a request.").

122. Neither the Census Bureau nor AAAG Gore is aware of any instance, other than the request to add a citizenship question to the decennial census questionnaire, in which DOJ has requested data from the Census Bureau and then declined to meet to discuss that request. PX-297, at RFA 201; Gore Dep. 282.

123. The fact that the Attorney General himself made the decision not to allow DOJ officials to meet with the Census Bureau is also highly unusual. Dr. Abowd, the Census Bureau's Chief Scientist and Defendants' own expert, testified that he was unaware of any other circumstance in which a Cabinet Secretary personally directed agency staff not to meet with the Census Bureau and that DOJ's refusal in this case was thus "unusual." Tr. 962-65. Dr. Abowd opined that Attorney General Sessions's decision constituted improper "political influence" on the decision-making process. Tr. 1267-68.

7. Efforts to Downplay Deviations from the Census Bureau's Standard Processes

124. As noted above (by way of background only), in recent decades, the Census Bureau has adhered to a fairly robust process in evaluating whether to add new questions to any data-collection instrument, including the census. AR 9865, 9867; AR 3560; AR 3890-91; Thompson Decl. ¶¶ 45, 47-49. That process includes rigorous *559pre-testing. In fact, the Census Bureau's "Statistical Quality Standards," issued in 2010, explicitly require pre-testing of any question to be added to a survey such as the census, unless the Census Bureau obtains a waiver or uses a question that has "performed adequately in another survey." PX-260, at vii, 8; see also PX-364 ("If there is insufficient evidence about how well a question performs, the question must be subjected to some form of questionnaire pretest.").

125. Initial plans for the 2020 census adhered to the Census Bureau's historical practices and Statistical Quality Standards. All questions on the 2010 census had been the subject of extensive cognitive testing and field testing. See Tr. 997. And the Census Bureau began testing potential improvements for the questions on race and ethnicity for the 2020 census more than ten years before the census, in 2008. See Thompson Decl. ¶ 49. The Census Bureau sought community feedback on the proposed changes in 2014 and 2015, and then conducted additional testing in 2015. See id. ¶¶ 50-53. Despite that extensive testing, the Census Bureau opted not to make the proposed changes to the questions on race and ethnicity because a final decision had not been made as of December 31, 2017, leaving inadequate time to deliver the final question wording to Congress two years prior to the census, as required by Section 141(f)(2). See id. ¶ 54.

126. Additionally, on April 29, 2016, Lisa Blumerman, Associate Director of Decennial Census Programs, issued a memorandum "officially document[ing] the U.S. Census Bureau's plan to develop and transmit to Congress" the questions planned for the 2020 decennial census. PX-271, at 1; see also Tr. 995. To the extent relevant here, the Memorandum invited "[f]ederal agencies with known uses of the 2020 Census or ACS content" to submit any requests for data collection by July 1, 2016. PX-271, at 3. Blumerman explained that "[f]inal proposed questions are based on the results of extensive cognitive testing, field testing, other ongoing research, and input from advisory committees." PX-271, at 4; Tr. 995-96.

127. Despite these plans and the Census Bureau's Statistical Quality Standards, neither the Census Bureau nor the Commerce Department conducted any pretesting of the citizenship question before Secretary Ross made the decision to add it to the 2020 census questionnaire. There was no cognitive testing, field testing, or randomized control testing of the question, nor was there any testing of the question within the context of the entire questionnaire or consultation with the Census Bureau's advisory committees or outside researchers with relevant expertise. See Tr. 156-57, 736-37, 925-26, 997-98, 1279-80; Thompson Decl. ¶¶ 60, 71, 77; Census Bureau 30(b)(6) Dep. 142-43, 426-27; Habermann Aff. ¶¶ 56-58. The one "end-to-end" test - in essence, a form of dress rehearsal - conducted for the 2020 census did not include the citizenship question. Tr. 92, 155-56, 998, 1096; Census Bureau 30(b)(6) Dep. 225.

128. Nor did the Census Bureau apply for, let alone receive, a waiver from the pre-testing requirement for the citizenship question. Tr. 1279. And while Secretary Ross opted to use a question that had previously appeared on the ACS, the record establishes that it has not "performed adequately" within the meaning of the Census Bureau's Statistical Quality Standards. For example, 32.7% of all people identified as noncitizens by administrative records reported themselves as citizens on the 2010 ACS. See January 19 Memo, at AR 1280. For the 2016 ACS, that figure was 34.7%. See id. Defendants' own expert witness, Dr. Abowd, acknowledged that *560the Census Bureau views this "disagreement" between the ACS survey responses and administrative records - which are generally viewed as more accurate - as a "problem with the ACS citizenship question." Tr. 1282. In fact, he opined that, in light of the disagreement rate, the citizenship question on the ACS has not "performed adequately." Id. at 1286-88; see also Defendants' Post-Trial Proposed Findings of Fact and Conclusions of Law Regarding Plaintiffs' Claims, Docket No. 546 ("Defs.' Post-Trial Br."), at 62, ¶ 420 (conceding that "the citizenship question does not appear to be performing adequately on the ACS").

129. Thus, the failure to conduct any pretesting of the proposed citizenship question on the decennial census questionnaire was a "significant deviation" from the Census Bureau's historical practices, its own mandatory Statistical Quality Standards, and its previously announced plans for the 2020 census. See Thompson Decl. ¶ 96; AR 3890-91; AR 2304; AR 9865, 9867; Tr. 1264. Yet, Secretary Ross and the Commerce Department tried to downplay, if not conceal, the degree of that deviation. The Court will address four examples of these efforts.

a. Secretary Ross's Claim that the Question Was Well Tested

130. First, Secretary Ross described the citizenship question as "well tested" in his March 26, 2018 Memorandum. Ross Memo 2, at AR 1314. He did not, however, describe that testing or even define what he meant by "well tested." See id. at AR 1313-20. Nor did Secretary Ross make any effort to reconcile his characterization of the question as "well tested" with the poor performance of the question on the ACS - that is, the high disagreement rate between survey responses and administrative records. See id. at AR 1316. Ironically, Secretary Ross himself noted this high disagreement rate when explaining his reasons for rejecting Alternative C. See id.

131. There is no basis in the record to dispute Dr. Abowd's assessment - which he conveyed to Secretary Ross in advance of the March 26, 2018 Memorandum - that the citizenship question was "well tested" for purposes of the ACS. See Tr. 1254-55, 1288; see also Tr. 568 (testimony of Thompson, former Census Bureau Director, that testing of the citizenship question for use on the ACS was "complete and thorough"). But the fact that the question was "well tested" for purposes of the ACS does not mean that the question is well tested for purposes of the decennial census. Nor does it mean that the testing was consistent with the Census Bureau's own standards and historical practices.

132. To the contrary, the record supports the conclusion of experts in the field that the question was not well - or even adequately - tested for purposes of the decennial census questionnaire. That view is shared by: (1) six former Census Bureau Directors, in both Republican and Democratic Administrations, including Dr. Thompson (whom Defendants' own expert described as "the expert in this trial who's most deserving of weight on his testimony), AR 8555-56; Tr. 1192; Thompson Decl. ¶¶ 93-96; (2) Plaintiffs' experts, Dr. Hillygus and Dr. Barreto, Tr. 157, 737-38; (3) the National Academies of Sciences, Engineering, and Medicine's Committee on National Statistics' Task Force on the 2020 Census, PX-539; and (4) the American Statistical Association, the American Sociological Association, and the Population Association of America, "three leading national associations of professional and academic statisticians, sociologists and demographers," Brief of the American Statistical Association et al. as Amici Curiae Supporting Plaintiffs, Docket No. 420-1, at 1, 4-9.

*561133. Defendants did not present any evidence to dispute the conclusion that the citizenship question has not been "well tested" for purposes of the 2020 census questionnaire. Instead, their own expert, Dr. Abowd, agreed that "[i]t would not be appropriate to describe it as well-tested in the context of the 2020 questionnaire. That is simply not true.... It hasn't ever been tested in that context." Tr. 1330.

134. There are several reasons that the testing conducted for the citizenship question on the ACS is not adequate for purposes of the decennial census questionnaire. First, although superficially similar, there are salient differences between the ACS and the decennial census. See Docket No. 456 ("Defs.' Pretrial Reply Br."), at 5 (conceding that the ACS is "a different instrument with different considerations and goals"). The primary purpose of the census is to obtain an "actual Enumeration" of the entire population of the country, see U.S. Const. art. I, § 2, cl. 3, while the ACS is "intended to provide information on the characteristics of the population, and the social and economic needs of communities," Thompson Decl. ¶ 32. And while the census strives for an "actual Enumeration" through an actual count of every household in the country, ACS estimates are statistical estimates based on a sample of United States households. Thompson Decl. ¶¶ 32-33; Tr. 805, 1027-28. Additionally, the ACS is a much longer questionnaire than the decennial census questionnaire. It includes dozens of questions - depending on household composition and housing status, a household might have to answer more than seventy questions - while the 2020 census questionnaire will contain either ten or eleven questions (depending on whether the citizenship question appears on it). See Tr. 87, 889, 1146; Thompson Decl. ¶ 63. A question concerning citizenship may take on added significance in the context of the much shorter decennial census questionnaire. See Thompson Decl. ¶ 63; Tr. 87-88. Thus, a test of the question in the context of the ACS questionnaire has only limited relevance to how the question will perform in the context of the census questionnaire.

135. Second, and related, the question order and context for the question in the ACS (as well as on the 1950 census questionnaire and the long-form questionnaire, both of which were also referenced by Secretary Ross in his March 26, 2018 Memorandum) are different than they would be on the census questionnaire. On the online ACS (and the prior census questionnaires), the question was preceded by a question about "nativity" - that is, place of birth - and only those who indicated that they were born outside of the United States were asked to disclose citizenship status. Tr. 159-60, 1274-75. By contrast, at present, the 2020 decennial census will ask about citizenship without a preceding nativity question - and it will be asked of all respondents. PX-489; Census Bureau 30(b)(6) Dep. 22-23; Thompson Decl. ¶ 66; Tr. 1275. Such differences in "sequencing" and context can affect response rates. Census Bureau 30(b)(6) Dep. 14; Tr. 159-60; Thompson Decl. ¶¶ 63-66.25

*562136. Finally, the ACS was last tested in 2006, and the macroenvironment has changed in important ways since then. See Tr. 737, 1252, 1258-59. In particular, the undisputed evidence - including the Census Bureau's own research - indicates that respondents are likely to react differently to a citizenship question in 2020 than they would have reacted only three years ago, let alone thirteen years ago. See id. at 616, 619-20, 737, 1258-59. Thus, testing conducted thirteen years ago has only limited relevance to how the question will perform on the 2020 census.

137. In short, while the citizenship question may have been "well tested" for the purposes of the ACS (and earlier versions of the census questionnaire, including the "long-form" questionnaire used until 2000), it is not "well," or even adequately, tested for purposes of the 2020 census questionnaire. Thus, Secretary Ross's statement that the question is "well tested" is misleading at best.

b. The Commerce Department Revises the Census Bureau's Description of the "Well-Established Process" for "Adding or Changing Content on the Census"

138. The record contains evidence of another, more deliberate, effort to downplay the degree to which Secretary Ross's decision to add the citizenship question deviated from the Census Bureau's past practices and standards. In late January 2018 - after the Census Bureau's initial, critical assessments of DOJ's request to add the question - senior aides to Secretary Ross, including Comstock and Uthmeier, developed a set of thirty-five questions for the Census Bureau to answer for the Secretary. AR 1976-78; Tr. 1004-05.

139. Dr. Abowd took the lead in coordinating the Census Bureau's responses to the questions. See Tr. 1005. In particular, he maintained the "control" or "master" copy of the responses to the questions, which represented the final and official position of the Census Bureau, as Dr. Abowd understood them. Id. 1010-11. After some back and forth with aides to Secretary Ross about some of the responses, see Tr. 1005, 1013-14; AR 9190, 13023; AR 2292; AR 2294-2305, Dr. Abowd provided a final set of responses on March 1, 2018 (with his memorandum comparing Alternatives C and D), see AR 9812-33.

140. The thirty-first question on the list asked: "What was the process that was used in the past to get questions added to the decennial Census or do we have something similar where a precedent was established?" AR 1296; AR 2303-04; AR 9832-33; AR 10900-01.

141. Victoria Velkoff, Chief of the American Community Survey Office at the U.S. Census Bureau, drafted the initial answer to this question on behalf of the Census Bureau. It stated in relevant part as follows:

The Census Bureau follows a well-established process when adding or changing content on the census or ACS to ensure the data fulfill legal and regulatory requirements established by Congress. Adding a question or making a change to the Decennial Census or the ACS involves extensive testing, review, and evaluation. This process ensures the change is necessary and will produce quality, useful information for the nation.

*563AR 2303; see AR 7644, 10950. The draft answer then described the "formal process for making content changes" laid out by the Census Bureau and OMB. AR 2304; AR 9832; AR 7644; AR 10901. That description was consistent with other Census Bureau documents describing the process to add a question or change the content of the decennial census, which are discussed above. AR 3560; AR 3890-91; PX-271, at 4.

142. Michael Walsh, Deputy General Counsel of the Commerce Department, and Sahra Park-Su, then Senior Policy Advisor at the Commerce Department, removed all references to the "well-established process" for adding or changing content on the census, see Docket No. 494-2 ("Park-Su Dep.") at 142; Tr. 1006-14; AR 9190, 13023. The answer to Question Thirty-One, as revised by Walsh and Park-Su, read as follows:

No new questions were added to the 2010 Decennial Census, so there is no recent precedent for considering a request to add questions to a decennial census. Consistent with longstanding practice for adding new questions to the ACS survey, the Census Bureau is working with relevant stakeholders to ensure that legal and regulatory requirements are fulfilled and that the question would produce quality, useful information for the nation. As you are aware, that process is ongoing. Upon its conclusion, you will have all of the relevant data at your disposal to make an informed decision about the pending request from the Department of Justice.

AR 9190, 13023.

143. The final version of the response to Question Thirty-One included in the original Administrative Record was further modified to read as follows:

Because no new questions have been added to the Decennial Census (for nearly 20 years), the Census Bureau did not feed bound by past precedent when considering the Department of Justices' request. Rather, the Census Bureau is working with all relevant stakeholders to ensure that legal and regulatory requirements are filled and that questions will produce quality, useful information for the nation. As you are aware, that process is ongoing at your direction.

AR 1296 (errors in original).

144. Dr. Abowd did not receive, review, or approve any of these revisions to the response to Question Thirty-One. See Tr. 1010-11. Nor were these revisions incorporated into Dr. Abowd's "control" copy of the responses. See id. To Dr. Abowd's knowledge, the response to Question Thirty-One is the only response that was changed between his final "control" copy and the copy that was submitted with the original Administrative Record. See id. at 1011.

c. Secretary Ross's Description of His Dealings with Nielsen

145. Third, Secretary Ross sought to bolster claims in his March 26, 2018 Memorandum by invoking his conversation with Christine Pierce, the Senior Vice President of Data Science for the Nielsen Company (US) LLC, see Ross Memo 3, 6, at AR 1315, 1318, but he materially mischaracterized the nature of that conversation.

146. Pierce testified by affidavit that Nielsen was contacted in the spring of 2018 about speaking with Secretary Ross regarding the census. See Docket No. 498-18 ("Pierce Aff."), ¶ 4. Despite multiple communications with Secretary Ross's staff, she was not advised in advance that the citizenship question was going to be a topic of the conversation. See id. ¶¶ 6, 8. Accordingly, she believed that the conversation would be about "the importance of the Census generally, the need for Nielsen and its commercial clients to have as complete *564and accurate a count as possible, and to advocate for full funding for Census operations." Id. ¶ 4.

147. On the evening of March 23, 2018, Pierce spoke by telephone with Secretary Ross and Walsh, the Commerce Department lawyer. Id. ¶ 7. As she testified, "it immediately became apparent that the citizenship question was the only topic of conversation." Id. ¶ 8.

148. During the conversation, Pierce told Secretary Ross "unequivocally" that she "was concerned that a citizenship question would negatively impact self-response rates," and she "explained that people are less likely to respond to a survey that contains sensitive questions." Id. ¶ 9. She "also added that increasing the length of a survey can reduce response rates" and "discussed the impact that lower response rates have on survey costs." Id. Finally, she "emphasized that Census non-response follow up operations are expensive because they require a full count and non-response follow up operations for the Decennial Census include in-person data collection."Id.

149. None of that appeared in the Ross Memo, which was issued only three days later. Instead, the Ross Memo stated, first, that Pierce had "confirmed that, to the best of [her] knowledge, no empirical data existed on the impact of a citizenship question on responses." Ross Memo 3, at AR 1315.

150. Pierce, however, testified that she "did not say" that. Pierce Aff. ¶ 10. She "discuss[ed] the importance of testing questions to understand any impacts to response ... [,] explained that a lack of testing could lead to poor survey results," and "confirmed that [she] was not aware of any such test of a citizenship question by the Census Bureau." Id.

151. The Ross Memo also asserted that Nielsen had "stated that it had added questions from the ACS on sensitive topics such as place of birth and immigration status to certain short survey forms without any appreciable decrease in response rates." Ross Memo 3, at AR 1315; see also id. at 6, at AR 1318 ("Additional empirical evidence about the impact of sensitive questions on survey response rates came from the SVP of Data Science at Nielsen. When Nielsen added questions on place of birth and time of arrival in the United States (both of which were taken from the ACS) to a short survey, the response rate was not materially different than it had been before these two questions were added.").

152. Pierce, however, testified that she "did not state that Nielsen had added 'questions concerning immigration status to short survey forms without any appreciable decrease in response rates.' " Pierce Aff. ¶ 12. She did explain that Nielsen had asked "certain questions from the ACS in [its] surveys and of [its] panelists, including place of birth and year of entry to the United States" and that these questions "had not caused a significant decline in response rates." Id. ¶ 13. But she "stressed the importance of specifically testing changes to questionnaires and that Nielsen had done such testing" with respect to those sensitive questions. Id. And she "did not suggest that Secretary Ross could draw parallels between the surveys conducted by Nielsen and the Decennial Census," as the two are "entirely different." Id. ¶¶ 13-14. Among other things, "Nielsen surveys are not conducted by a government agency and are not required by law"; their purpose is to "understand consumer purchases and media usage," not to count the population; they are "not required to count all people"; response rates "generally range" from only 5% to 40% and if someone does not participate Nielsen will *565simply "recruit" someone else to take his or her place; and, "unlike the Census, Nielsen provides incentives - usually cash - for filling out [its] surveys." Id. ¶ 14.

153. There is no indication in the Administrative Record (or elsewhere in the trial record) that Secretary Ross communicated with anyone at Nielsen other than Pierce. Further, Pierce is not aware of any other relevant communications between Nielsen and the Department of Commerce regarding the citizenship question. Id. ¶ 15.

154. The Court credits Pierce's account of the March 23, 2018 conversation with Secretary Ross. Indeed, Defendants chose not to even cross-examine her (and did not cite her testimony even once in their extensive post-trial briefing).

d. Comstock's Testimony About the Census Bureau's Analyses

155. Finally, the Court finds that Comstock's testimony in this matter about his and Secretary Ross's dealings with the Census Bureau in the period leading up to the Ross Memo was materially misleading. Notably, by his own account, Comstock was more "involved in the citizenship question" than anyone else at the Commerce Department between early 2017 and the issuance of the Ross Memo. Comstock Dep. 340-41. That characterization is borne out by the evidence in the Administrative Record and the trial record.

156. During his videotaped deposition, Comstock was asked about the statement in Dr. Abowd's January 19 Memo that adding a citizenship question to the census would be "very costly, harm[ ] the quality of the census count, and would use substantially less accurate citizenship status data than are available from administrative sources." January 19 Memo, at AR 1277; see Comstock Dep. 309-12. Comstock acknowledged the statement, but he testified that it "overstate[d] the case they made further in the document" and that it was "not an accurate representation of what's actually reflected in the document." Comstock Dep. 312.

157. Additionally, he testified that the statement was not "the final conclusion" or "the position" of the Census Bureau, id. at 312-13; that in a meeting with Dr. Abowd and others (presumably the February 12, 2018 meeting), "they stood by the entire analysis," but "not necessarily that statement," id. at 314; that it was not his "understanding" that "that particular statement represent[ed] the view of the Census Bureau," id. ; and that it was "not representative of the data that was presented to us in the course of extensive discussions," but rather "an early statement that mischaracterize[d] the final conclusions that we understood," id. at 316-17.

158. Based on an assessment of Comstock's demeanor and a review of the other evidence in the record, the Court declines to credit that testimony. For one thing, the entirety of the January 19 Memo is consistent with, and supports, the statement that adding a citizenship question to the census would be "very costly, harm[ ] the quality of the census count, and would use substantially less accurate citizenship status data than are available from administrative sources." January 19 Memo at AR 1277-85.

159. For another, there is no indication anywhere else in the record that, in the February 12, 2018 meeting or otherwise, Dr. Abowd or his colleagues at the Census Bureau ever retreated from the statement. To the contrary, Dr. Abowd testified at trial (credibly) that he adhered to the statement and conclusions in the January 19 Memo. See Tr. 882-92, 922-23, 950-54, 958-59.

160. In fact, if anything, the Census Bureau's assessment of the harms and costs of adding a citizenship question only grew more pessimistic after the January *56619 Memo. While the January 19 Memo conservatively estimated that adding the citizenship question would cause a 5.1% increase in the non-response rate of noncitizen households, AR 1280, the Census Bureau has since updated its estimate of that figure to 5.8%. See PX-162 ("Brown Memo"), at 38, 42. And while the January 19 Memo conservatively estimated that adding the citizenship question would increase the costs of the 2020 census by at least $27.5 million (a figure that did not even include anticipated increases in communications costs), AR 1282, the Census Bureau's current best estimate is that it would cost $82.5 million more. See Tr. 952, 1249-50.26

161. During his deposition, Comstock also acknowledged his awareness of the Census Bureau's view (set forth in the March 1 Memo) that Alternative B (adding the citizenship question) "would result in poorer quality citizenship data" than Alternative C (using administrative records) "and still have all the cost and quality implications of Alternative B" outlined in the January 19 Memo. Comstock Dep. 320. When asked about that view, Comstock testified that "there was [an] iterative exchange in which the conclusions of the Census Bureau to staff and some of their assertions did not hold up under cross-examination." Id. at 321.

162. Once again, based on an assessment of Comstock's demeanor and a review of the other evidence in the record, the Court declines to credit that testimony.27 Among other things, there is no indication anywhere in the record that the conclusions and assertions set forth in the March 1 Memo "did not hold up" or that, "under cross-examination" or otherwise, the Census Bureau retreated from them. To the contrary, Dr. Abowd testified at trial (credibly) that he adhered to the conclusions in the March 1 Memo. See Tr. 966-76.

8. The Genesis of the DOJ Letter Was Kept from the Census Bureau

163. The revisions to the Question Thirty-One response were not the only thing about which Dr. Abowd and his colleagues at the Census Bureau were left in the dark. They were also never told that Secretary Ross had begun considering a citizenship question in early 2017.

164. Indeed, it was not until Secretary Ross's June 21, 2018 Memo and the subsequent disclosures in this litigation (some of which are now part of the Administrative Record and some of which are not) that Dr. Abowd and others at the Census Bureau learned that Secretary Ross had begun considering a citizenship question in early 2017; that, as part of that consideration, Secretary Ross communicated with Bannon and Kobach; that, as early as May 2017, Secretary Ross had expressed frustration about nothing having been done about his "months old request" to "include *567the citizenship question"; that the Commerce Department had initiated conversations with DOJ about requesting the citizenship question rather than the other way around; and that the Attorney General himself directed the technical experts at DOJ not to meet with the Census Bureau to discuss alternative options. See Tr. 964, 1016-21.

165. Of course, Secretary Ross and his aides were not required to inform Dr. Abowd or others at the Census Bureau that they were considering whether to add a citizenship question to the census. As a de facto matter, however, the degree to which the origins of the decision were kept from those who worked hard to promptly evaluate DOJ's request was unusual and noteworthy. Moreover, had Secretary Ross and his aides involved the Census Bureau earlier, the experts there might have been able to conduct appropriate testing of the question in the context of the census itself. Indeed, by not revealing his consideration of the citizenship question before December 2017, Secretary Ross prevented those experts from conducting a study to quantify whether and to what extent the question would result in a differential undercount even with NRFU operations. See Tr. 1291, 1301.

166. A poignant exchange between counsel and Dr. Abowd at trial highlights the unusual - and impactful - nature of Secretary Ross's failure to consult the Census Bureau earlier. When asked whether he had been under the impression that all his work in the wake of DOJ's request "mattered as far as the Secretary's decision-making process," Dr. Abowd responded: "I was under the impression that it mattered in the conduct of the 2020 census, yes." Tr. 1021. Counsel then asked: "And no one ever told you during that entire period of time that Commerce Department officials had initiated this entire process, correct?" Dr. Abowd then answered: "No one told me that, but I am still under the impression it matters for the 2020 census." Id. at 1022. As he did so, Dr. Abowd choked up and visibly held back tears.

9. Findings Regarding the Timing of, and Reasons for, Secretary Ross's Decision

167. It is hard, if not impossible, to identify with precision when Secretary Ross first made the decision to add a citizenship question to the 2020 census - particularly in the absence of a deposition of Secretary Ross himself. But based on the foregoing record, the Court finds - by well more than a preponderance of the evidence - that Secretary Ross had made the decision months before DOJ sent its letter on December 12, 2017.

168. That conclusion is supported by evidence in the Administrative Record alone. First and most obviously, it is supported by Secretary Ross's May 2, 2017 email to Comstock expressing "mystif[ication]" as to why "nothing" had been done "in response to" his "months old request that we include the citizenship question," AR 3710 (emphasis added), and Comstock's reply later the same day that "we will get that in place" and "[w]e need to work with Justice to get them to request that citizenship be added back as a census question," id.28 On its face, Secretary *568Ross's email supports the conclusion that he had made the decision to "include" the question before May 2, 2017 - and thus before receiving DOJ's request on December 12, 2017. After all, his reference was not to a "months old" request to analyze inclusion of the question, but to his request, from a supervisor to his staff, to "include" it.

169. Second, the conclusion that Secretary Ross actually made the decision before DOJ sent its letter in December 2017 is further supported by Comstock's August 11, 2017 email to Secretary Ross emphasizing the "need to be diligent in preparing the administrative record" because the "issue will go to the Supreme Court." AR 12476. Plaintiffs characterize that email as evidence that "Secretary Ross and his senior staff agreed ... to whitewash the administrative record." Plaintiffs' Joint Proposed Post-Trial Conclusions of Law, Docket No. 545-1 ("Pls.' Proposed Conclusions"), ¶ 354. The parsimonious nature of the initial Administrative Record in these cases, and the steps that Secretary Ross and his aides took to downplay, if not conceal, the significance of his decision, do provide some basis to draw such an uncharitable inference. But there is no need to do so in light of a more obvious and significant inference to be drawn from Comstock's email. That is, the email makes clear that, by August 11, 2017, Secretary Ross had already decided to add the citizenship question to the 2020 census. After all, the only reason to believe that "the issue" would definitely "go to the Supreme Court" was if Secretary Ross had decided to add the question; if there was a chance that Secretary Ross, after considering the issue with an open mind, was going to preserve the status quo, Comstock would have had no reason to state with confidence that the issue "will" go to the Supreme Court. Nor would there have been any reason to "prepar[e] the administrative record" to memorialize or justify a decision that might never even be made.

170. Third, the same conclusion is supported by Uthmeier's August 11, 2017 email to Comstock, which attached his legal memorandum concerning the citizenship question that was later used by AAAG Gore in drafting the Gary Letter. PX-607 (AR). In that email, Uthmeier stated that he had "some new ideas/recommendations on execution " and that "our hook" was that "[u]ltimately, we do not make decisions on how the data should be used for apportionment, that is for Congress (or possibly the President) to decide." PX-607 (AR) (emphasis added). As with Comstock, Uthmeier's choice of words makes sense only if he understood that there was already a decision to "execut[e]." Taken together, therefore, the record evidence reveals an agency staff in search of a rationale for a decision their boss had already made, before December 12, 2017.

171. More broadly, the Court's conclusion is supported by the general chronology leading up to the decision, as revealed by evidence in the supplemented Administrative Record. That evidence makes clear that Secretary Ross and his staff did more than merely "inquire[ ] whether the [DOJ] would support, and if so would request , inclusion of a citizenship question as consistent with and useful for enforcement of the Voting Rights Act," AR 1321 (emphasis added) - although that alone would have been significant. Instead, the evidence reveals that Secretary Ross was aggressively pressing to add a citizenship question to the census before the idea of justifying it on the basis of VRA enforcement was first floated, AR 3702, 3710; that, prompted by Neuman, Secretary Ross's own aides came up with the legal rationale DOJ could rely upon for addition of the question, PX-188 (AR), PX-565 (AR); that, *569believing they needed another agency to justify adding the question, they actively lobbied other agencies to make the request and, when that initially proved unsuccessful, explored whether they could do it themselves, AR 12755-56; that, undeterred by the lack of any interest from DOJ staff, Secretary Ross intervened directly with Attorney General Sessions in order to secure the request they believed they needed, AR 1321, 2528, 2636, 4004; and that Secretary Ross's aides then fed DOJ with the rationale for the request rather than vice-versa, AR 2461; PX-607 (AR).

172. Notably, all of this evidence is in the Administrative Record alone - not in Defendants' initial production, to be sure, but in the Administrative Record as stipulated by the parties. See Docket No. 523, at Joint Stip. ¶ 63. What little evidence remains "outside" the Administrative Record after the parties' stipulations, however, only strengthens the conclusion that Secretary Ross had made his decision even before DOJ's request. Most notably, Comstock - the aide more involved in Secretary Ross's early deliberations on the issue than any other - testified that the Secretary had made a "request" to add the citizenship question "sometime in the spring" - "[p]otentially" as early as March 10, 2017. Comstock Dep. 146; see also id. at 337 (conceding that the "initial impetus for putting the citizenship question on the 2020 census" was Secretary Ross, not DOJ, and that, "shortly after he was confirmed," he "request[ed] the question be put on the census").29

173. Secretary Ross's actual reasons for his decision are even foggier than the precise timing of his decision. There is no writing of any kind - either in the Administrative Record or produced in discovery, either authored by Secretary Ross or by anyone else - that describes the reasons why Secretary Ross wanted to add a citizenship question within weeks of his confirmation as Secretary. See AR 1-13024. Moreover, Comstock testified that Secretary Ross never disclosed why he wanted to add a citizenship question to the census - and that Comstock never asked him, perhaps because Comstock believed that the reason might or might not be "legally valid." Comstock Dep. 267; see id. at 112, 171-72, 251-55, 340-41. Teramoto, Secretary Ross's own Chief of Staff, similarly testified that she had no knowledge of why Secretary Ross wanted to add a citizenship question. Teramoto Dep. 32.

174. While the Court is unable to determine - based on the existing record, at least - what Secretary Ross's real reasons for adding the citizenship question were, it does find, by a preponderance of the evidence, that promoting enforcement of the VRA was not his real reason for the decision. Instead, the Court finds that the *570VRA was a post hoc rationale for a decision that Secretary had already made for other reasons.

175. Once again, that conclusion finds support in the Administrative Record alone. For one thing, it finds support in the very same evidence that supported the conclusion that Secretary Ross committed to adding the citizenship question months before he even received the request from DOJ. By definition, Secretary Ross's original and actual rationale could not have been promotion of better VRA enforcement because the record reveals that he had made up his mind well before DOJ even agreed to submit the request to him.

176. Moreover, it finds support in the sheer number of Commerce Department communications predating the DOJ letter - with staff, with Kobach, and with DOJ and DHS - none of which mention the VRA rationale, but all of which reflect Secretary Ross's anxious desire to add a citizenship question to the census. See, e.g. , AR 763-64, 2424, 2458, 2521, 3710, 3984, 4004. And it finds support in Comstock's aggressive - and initially unsuccessful - efforts to lobby DOJ and DHS officials with no responsibility for VRA enforcement. See AR 2458, 2462; PX-298(R), at RFA 73, 91-95. Those efforts make clear that the goal of Secretary Ross and his aides was to launder their request through another agency - that is, to obtain cover for a decision that they had already made - and that the reasons underlying any request from another agency were secondary, if not irrelevant.

177. Once again as well, extra-record evidence merely strengthens the conclusion that Secretary Ross's actual rationale was something other than VRA enforcement - and that a belief that he needed another agency to request the question, rather than a belief that adding a citizenship question was necessary to enhance VRA enforcement, motivated his aggressive efforts to stimulate a request from DOJ.

178. First, notwithstanding his otherwise self-serving testimony, Comstock conceded in his deposition testimony that he did not believe that Secretary Ross's unstated reasons to add a citizenship question in early 2017 would "clear [the] legal thresholds" set by OMB and federal law. Comstock Dep. 153-54. Indeed, he admitted that he viewed his job as finding a "legal rationale" to support the Secretary's request (and then finding an agency to make the ask) and that he did not "need to know what" the Secretary's actual "rationale might be, because it may or may not be one that is ... legally-valid." Id. at 181, 267. That testimony constitutes a near-confession that the VRA rationale was a post hoc concoction to justify a decision made for other reasons - that is, that Comstock felt the need to launder the request through another agency.

179. Second, there is reason to doubt that DOJ itself believed the VRA rationale in the Gary Letter. The VRA was enacted in 1965, fifteen years after a citizenship question last appeared on the decennial census questionnaire for all households. Yet, until Secretary Ross and his senior aides planted the seed, DOJ had never before cited a VRA-related need for citizenship data from the decennial census; never before asserted that it had failed to bring or win a VRA case because of the absence of such data; and never before claimed that it had been hampered in any way by relying on citizenship estimates obtained from sample surveys. After fifty-four years of VRA enforcement, it was the Department of Commerce that first proposed the idea. In fact, DOJ did not even take the bait when Comstock first approached staff with the idea. It was not until Secretary Ross intervened directly *571with Attorney General Sessions that DOJ agreed to carry the baton forward based on the rationale that Secretary Ross's aides had come up with.

180. Additionally, AAAG Gore, the actual author of the Gary Letter, acknowledged that none of the DOJ components with principal responsibility for enforcing the VRA requested the addition of a citizenship question; instead, he drafted the letter solely in response to the Secretary's request. Gore Dep. 64-67, 94-95. He also testified that he drafted the letter without knowing if citizenship data based on responses to a citizenship question on the census would have smaller or larger margins of error, or would be any more precise, than the existing citizenship data on which DOJ currently relies. See id. at 225-28.

181. Beyond that, the odd nature of DOJ's request and events thereafter suggest that the goal was not to obtain better CVAP data for purposes of VRA enforcement, but merely to provide cover for Secretary Ross's decision to add a citizenship question. It would have been one thing for DOJ to ask the Commerce Department for better CVAP data and leave it to the Commerce Department, which is ultimately tasked with deciding how to obtain needed data, to figure out how best to meet that need. But DOJ went further and, going beyond its role, explicitly asked the Commerce Department to add the citizenship question to the census.

182. Of course, there is no mystery why DOJ did so. By Secretary Ross's own admission, the Department of Commerce did not merely ask DOJ if existing data was adequate; instead, making clear that he had prejudged the solution to a problem that DOJ might or might not even have, he and his staff affirmatively asked DOJ if it "would support, and if so would request, inclusion of a citizenship question ." June 21 Supplemental Memo (emphasis added). And, despite the DOJ staff's own lack of interest, Attorney General Sessions was only happy to oblige. As his aide put it to Teramoto: "[W]e can do whatever you all need us to do .... The AG is eager to assist." AR 2651.

183. Further, when the Census Bureau sought to meet with representatives of DOJ to discuss other, less harmful ways of meeting its need for data, Attorney General Sessions vetoed any such meeting. Had DOJ's interest genuinely been to get better CVAP data, rather than providing a post hoc rationale for Secretary Ross's resolve to add a citizenship question to the census, there is no explanation for that decision.

184. Finally, the Court's conclusion is supported by the sheer number of ways in which Secretary Ross and his aides tried to avoid disclosure of, if not conceal, the real timing and the real reasons for the decision to add the citizenship question. Those include:

• The curated and highly sanitized nature of the Administrative Record initially filed by Defendants in this matter, see Docket No. 193, at 1; July 3 Tr. 80-82, which (general background materials aside) omitted all materials relating to the deliberations and communications of Secretary Ross and his aides prior to the Gary Letter (despite Comstock's and Secretary Ross's acknowledgment as early as August 2017 of the need to be "diligent in preparing the administrative record," AR 12476);

• The lack of any record (even reconstructed) of various important steps along the way (despite, again, the stated intent to be diligent in preparing the administrative record), including but not limited to Secretary Ross's early discussions with other *572officials regarding addition of the citizenship question, see PX-302, at 2-3; Comstock Dep. 112; the September 6, 2017 meeting of Secretary Ross and his aides, see AR 1411-12, 1996-97; Comstock Dep. 221; Teramoto Dep. 58-61; Kelley Dep. 105-07; Secretary Ross's conversations with Attorney General Sessions that prompted DOJ to agree to request the question, Gore Dep. 83; and Secretary Ross's February 12, 2018 meeting with Dr. Abowd and others from the Census Bureau - his one and only meeting with the technical experts at the Census Bureau, see AR 9450;

• The failure to disclose to subject matter experts at the Census Bureau that the issue was on the table prior to the Gary Letter, a failure that prevented those experts from conducting rigorous testing of the proposed question, Tr. 1018-22;

• The revisions to the Census Bureau's answer to Question Thirty-One, which were plainly intended to downplay the degree to which Secretary Ross departed from the process ordinarily used to consider new questions on the census, Tr. 965, 1010-11;

• The misleading, if not false, statements in the Ross Memo, including but not limited to its suggestion that Secretary Ross began considering the issue only after receiving the Gary Letter in December 2017, AR 1321, and the descriptions of the communications with Nielsen, compare Ross Memo 3, 6, at AR 1315, 1318, with Pierce Aff. ¶¶ 9, 10, 12-14;

• Secretary Ross's "admittedly imprecise," Petition for a Writ of Mandamus at 20, In re U.S. Dep't of Commerce , (Oct. 29, 2018) (No. 18-557), 2018 WL 5617904, at *24, if not false, testimony before Congress, including but not limited to his statements that he was "not aware of any" discussions with "anyone in the White House" (despite his own conversation with Bannon), that DOJ "initiated the request for inclusion of the citizenship question" (despite the fact that it was plainly initiated by the Commerce Department), and that he was responding "solely" to DOJ's request (despite the fact that it was he who had generated that request in the first place), see Recitation of Facts ¶¶ 70, 72, 98-102; and

• Comstock's misleading, if not false, testimony regarding the Census Bureau's analyses in this litigation, see Comstock Dep. 305-25.

Those acts and statements are not the transparent acts and statements one would expect from government officials who have decided, for bona fide and defensible reasons, to change policy. Nor are they the acts and statements of government officials who are merely trying to cut through red tape. Instead, they are the acts and statements of officials with something to hide.

STANDING

The Court begins its legal analysis, as it must, with the threshold question of whether any Plaintiff has standing to bring the claims asserted. Defendants contend, as they have throughout this litigation, that the Court lacks subject-matter jurisdiction because Plaintiffs cannot prove - and, after trial, have not proved - that they have suffered, or will suffer, injury in fact that is fairly traceable to Secretary Ross's decision to add a citizenship question on the 2020 census. See Defs.' Post-Trial Br. 8-44, 66-72. Notably, although they filed over fourteen applications seeking to avoid trial, Defendants now concede *573that trial was necessary to resolve the issue of standing. See Tr. 1421-22.30 Further, they concede that the Court may, and indeed should, look at evidence beyond the Administrative Record to make findings of fact relevant to the standing inquiry. See id. To avoid any confusion, the Court sets forth those findings separately in the discussion that follows. And for reasons the Court will explain, those findings compel the conclusion that Plaintiffs do indeed have standing to assert their claims.

A. General Legal Standards

Article III of the United States Constitution extends the "judicial Power" of the United States to "Cases" and "Controversies." U.S. Const. art. III, § 2. This means that all suits filed in federal court must be "cases and controversies of the sort traditionally amenable to, and resolved by, the judicial process." Steel Co. v. Citizens for Better Env't , 523 U.S. 83, 102, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998). Courts implement this limit on the judicial power by ensuring that at least one plaintiff in any federal case has "standing." See Rumsfeld v. Forum for Acad. & Institutional Rights, Inc. , 547 U.S. 47, 53 n.2, 126 S.Ct. 1297, 164 L.Ed.2d 156 (2006) (noting that, in a case with "numerous" plaintiffs, "the presence of one [plaintiff] with standing is sufficient to satisfy Article III's case-or-controversy requirement"); accord Trump v. Hawaii , --- U.S. ----, 138 S.Ct. 2392, 2416, 201 L.Ed.2d 775 (2018). Standing, in turn, is measured by a "familiar three-part test," which requires a plaintiff to show (1) "an injury in fact, (2) that is fairly traceable to the challenged conduct of the defendant, and (3) that is likely to be redressed by a favorable judicial decision." Gill v. Whitford , --- U.S. ----, 138 S.Ct. 1916, 1929, 201 L.Ed.2d 313 (2018) (internal quotation marks omitted); accord Spokeo, Inc. v. Robins , --- U.S. ----, 136 S.Ct. 1540, 1547, 194 L.Ed.2d 635 (2016). The plaintiff must make this showing "in the same way as any other matter on which the plaintiff bears the burden of proof, i.e. , with the manner and degree of evidence required at the successive stages of the litigation." Lujan v. Defenders of Wildlife , 504 U.S. 555, 561, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992). Ultimately, the facts "(if controverted) must be supported adequately by the evidence adduced at trial." Id. (internal quotation marks omitted).

Injury in fact is the "first and foremost of standing's three elements." Spokeo , 136 S.Ct. at 1547 (internal quotation marks and alterations omitted). "To establish injury in fact, a plaintiff must show that he or she suffered an invasion of a legally protected interest that is concrete and particularized and actual or imminent, not conjectural or hypothetical." Id. at 1548 (internal quotation marks omitted). An injury "need not be actualized" to satisfy Article III. Davis v. Fed. Election Comm'n , 554 U.S. 724, 734, 128 S.Ct. 2759, 171 L.Ed.2d 737 (2008). A "future injury" can suffice, so long as it is "certainly impending, or there is a substantial risk that the harm will occur."

*574Susan B. Anthony List v. Driehaus , 573 U.S. 149, 157, 134 S.Ct. 2334, 189 L.Ed.2d 246 (2014) (emphasis added) (internal quotation marks omitted); see also Clapper v. Amnesty Int'l USA , 568 U.S. 398, 414 n.5, 133 S.Ct. 1138, 185 L.Ed.2d 264 (2013) (noting that plaintiffs need not "demonstrate that it is literally certain that the harms they identify will come about").31 Thus, for example, in a previous challenge to the conduct of the decennial census, the Supreme Court found that the plaintiffs had established standing "on the basis of the expected effects" of the challenged conduct "on intrastate redistricting" - in particular, based on a factual finding that certain jurisdictions were "substantially likely ... [to] suffer vote dilution in state and local elections." Dep't of Commerce v. U.S. House of Representatives , 525 U.S. 316, 332-33, 119 S.Ct. 765, 142 L.Ed.2d 797 (1999) (emphasis added) (internal quotation marks omitted). Ultimately, the injury-in-fact requirement is meant to "ensure that the plaintiff has a personal stake in the outcome of the controversy." Susan B. Anthony List, 573 U.S. at 158, 134 S.Ct. 2334 (internal quotation marks omitted).

Standing's second element requires proof that the plaintiff's injury is "fairly traceable" to the defendant's challenged conduct. Put differently, "there must be a causal connection between the injury and the conduct complained of - the injury has to be fairly traceable to the challenged action of the defendant, and not the result of the independent action of some third party not before the court." Lujan , 504 U.S. at 560, 112 S.Ct. 2130 (alterations and internal quotation marks omitted). Significantly, though, "[p]roximate causation is not a requirement of Article III standing, which requires only that the plaintiff's injury be fairly traceable to the defendant's conduct." Lexmark Int'l, Inc. v. Static Control Components, Inc. , 572 U.S. 118, 134 n.6, 134 S.Ct. 1377, 188 L.Ed.2d 392 (2014) (emphases added); see also Rothstein v. UBS AG , 708 F.3d 82, 91 (2d Cir. 2013) ("[T]he 'fairly traceable' standard is lower than that of proximate cause."). That "requires no more than de facto causality." Block v. Meese , 793 F.2d 1303, 1309 (D.C. Cir. 1986) (Scalia, J.). Relatedly, for an injury to be "fairly traceable" to a defendant's conduct, that conduct need not be "the very last step in the chain of causation." Bennett v. Spear , 520 U.S. 154, 169, 117 S.Ct. 1154, 137 L.Ed.2d 281 (1997). To be sure, traceability may be "substantially more difficult to establish" where it depends on a lengthier causal chain, including intervening actions by third parties, but it "is not precluded" in such circumstances. Lujan , 504 U.S. at 562, 112 S.Ct. 2130. As the Supreme Court has explained, even where "standing depends on the unfettered choices made by independent actors not before the courts," choices that "the courts cannot presume either to control or to predict," the traceability requirement is nonetheless satisfied if the plaintiff "adduce[s] facts showing that those choices have been or will be made in such manner as to produce causation and permit redressability of injury." Id. ; see also Bennett , 520 U.S. at 169, 117 S.Ct. 1154 (holding that where the defendant's conduct has a "determinative or coercive effect upon the action of someone else" the traceability requirement is satisfied).

Third and finally, a plaintiff's injury must be "redressable" by the relief sought - that is, "it must be likely, as *575opposed to merely speculative, that the injury will be redressed by a favorable decision." Lujan , 504 U.S. at 561, 112 S.Ct. 2130 (internal quotation marks omitted). Although "the 'fairly traceable' and 'redressability' components of the constitutional standing inquiry were initially articulated" as " 'two facets of a single causation requirement,' " there is a difference between them: "[T]he former examines the causal connection between the assertedly unlawful conduct and the alleged injury, whereas the latter examines the causal connection between the alleged injury and the judicial relief requested." Allen v. Wright , 468 U.S. 737, 753 n.19, 104 S.Ct. 3315, 82 L.Ed.2d 556 (1984) (quoting C. WRIGHT , LAW OF FEDERAL COURTS § 13, at 68 n.43 (4th ed. 1983) ). "[T]he very essence of the redressability requirement" is that a request for "[r]elief that does not remedy the injury suffered cannot bootstrap a plaintiff into federal court." Steel Co. , 523 U.S. at 107, 118 S.Ct. 1003. But if there is "a likelihood that the requested relief will redress the [plaintiff's] injury," the requirement is satisfied. Id. at 103, 118 S.Ct. 1003 ; see also Friends of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc. , 528 U.S. 167, 185-86, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000) ("[F]or a plaintiff who is injured or faces the threat of future injury due to illegal conduct ongoing at the time of suit, a sanction that effectively abates that conduct and prevents its recurrence provides a form of redress.").

The Supreme Court's decision in Davis illustrates how these three requirements should be applied in cases that allege, at least in part, prospective risks of harm. In Davis , a candidate for the House of Representatives challenged Section 319(a) of the Bipartisan Campaign Reform Act of 2002 ("BCRA"), Pub. L. No. 107-155, 116 Stat. 81, 109-11 (2002) (codified at 52 U.S.C. § 30117 ), which increased campaign contribution limits for any candidate whose opponent's personal campaign expenditures exceeded her own by a certain amount. See Davis , 554 U.S. at 729, 128 S.Ct. 2759. The Federal Election Commission argued that Davis lacked standing to challenge the provision for two reasons: first, when he filed the lawsuit, his personal expenditures had not yet triggered the heightened contribution limits for his opponent; and second, once his expenditures did trigger the heightened limits (after the lawsuit was filed), Davis's opponent chose not to take advantage of them. See id. at 734, 128 S.Ct. 2759. The Court swiftly rejected those arguments in an opinion by Justice Alito that was joined in relevant part by every member of the Court. See id. at 752 n.4, 128 S.Ct. 2759 (Stevens, J., dissenting). The standing inquiry, Justice Alito explained, is "focused on whether the party invoking jurisdiction had the requisite stake in the outcome when the suit was filed." Id. at 734, 128 S.Ct. 2759. At that time, Davis "had declared his candidacy and his intent to spend more" than the relevant threshold, and "there was no indication that his opponent would forego" the benefits of Davis' choice - namely, the heightened contribution limits. Id. Moreover, the record "indicated that most candidates who had the opportunity to receive expanded contributions had done so." Id. at 735, 128 S.Ct. 2759. "In these circumstances," the Court concluded, "Davis faced the requisite injury from § 319(a) when he filed suit." Id.

Davis yields three insights relevant here. First, it establishes that, in regulating the federal courts' power to dispense prospective relief, Article III is concerned with the risk of future injury, rather than its ultimate realization. After all, the Court found that Davis had standing even though the harm he feared never materialized. Second, the opinion makes plain that the risk of future injury may *576satisfy Article III's injury and causation requirements even if several steps on the causal chain still stand between a defendant's conduct and the plaintiff's injury when the case is filed. Davis, for example, was at least three steps away from suffering any concrete harm: He had to spend a sufficient amount of his own money; his opponent had to refrain from a comparable level of self-funding, see id. at 729 & n.5, 128 S.Ct. 2759 (explaining that the heightened contribution limits were triggered when "a statistic that compares the expenditure of personal funds by competing candidates" reached a particular level); and his opponent had to then take advantage of the law by accepting heightened contributions. Even so, the Court found that Davis faced "a real, immediate, and direct injury ... when he filed suit." Id. at 734, 128 S.Ct. 2759. Third, and related, Davis underscores that, under longstanding precedent, a party can establish standing to challenge government action even where its theory of injury depends on "choices made by independent actors not before the courts," so long as - through statistical analysis, common sense, or record evidence - the court can "predict" that those independent actors will respond to the government action in a way that causes the injury. Lujan , 504 U.S. at 562, 112 S.Ct. 2130 (internal quotation marks omitted). In Davis , the plaintiff's theory of injury depended on the assumption that his opponent would be sufficiently incentivized to take advantage of the heightened contribution limits, once triggered. The Court deemed that assumption valid based on little more than evidence that "most candidates who had the opportunity to receive expanded contributions had done so." Id. at 735, 128 S.Ct. 2759 (emphasis added). Notably, the Court did not require proof that the government conduct had a coercive effect on the third party's action; evidence that allowed the Court to predict how the third party would likely act in response to the government action was sufficient. See id. ; see also Lujan , 504 U.S. at 562, 112 S.Ct. 2130 (noting that, when injury depends on the conduct of third parties, it is sufficient to show "choices have been or will be made in such a manner as to produce causation and permit redressability" (emphasis added) ); Nat. Res. Def. Council v. Nat'l Highway Traffic Safety Admin. , 894 F.3d 95, 104-05 (2d Cir. 2018) (finding "the agency's own pronouncements," as well as "[c]ommon sense and basic economics," supported a conclusion that an "increased penalty has the potential to affect [third parties'] business decisions and compliance approaches" in a manner that would result in harm to the petitioners (internal quotation marks omitted) ); Texas v. United States , 809 F.3d 134, 156 (5th Cir. 2015) (finding that Texas had established the necessary causal connection between the Deferred Action for Parents of Americans and Lawful Permanent Residents ("DAPA") program and a future injury because DAPA would have "enabled" third parties "to apply for driver's licenses" and there was "little doubt that many would do so"), aff'd by an equally divided Court , --- U.S. ----, 136 S.Ct. 2271, 195 L.Ed.2d 638 (2016).

B. Findings of Fact Related to Standing

As noted, the three elements of standing must be established "in the same way as any other matter on which the plaintiff bears the burden of proof, i.e. , with the manner and degree of evidence required at the successive stages of the litigation." Lujan , 504 U.S. at 561, 112 S.Ct. 2130. Accordingly, at this stage, standing must be supported by undisputed facts or by a preponderance of "the evidence adduced at trial." Id. (internal quotation marks omitted); see Defs.' Post-Trial *577Br. 67, ¶¶ 7, 9 (agreeing that the relevant standard is a preponderance of the evidence); Tr. 1477-78 (same). Pursuant to Rule 52(a) of the Federal Rules of Civil Procedure and based on the extensive record compiled at trial, the Court therefore makes the following findings of fact with respect to Plaintiffs' standing. Although, as noted, "the presence of one party with standing is sufficient to satisfy Article III's case-or-controversy requirement," Rumsfeld , 547 U.S. at 53 n.2, 126 S.Ct. 1297, in the interest of making a comprehensive record so as to facilitate appellate review and avoid the need for remand, the Court makes findings of fact - and, below, arrives at conclusions of law - with respect to most, if not all, Plaintiffs.32

1. Background

185. The goal of the census is to count everyone residing in the United States, but the census has never achieved that goal. See Census Bureau 30(b)(6) Dep. 254. In each census, some people are "counted twice" (referred to as "erroneous enumerations") and others are not counted at all (referred to as "omissions"). Id. When the number of omissions exceeds the number of erroneous enumerations, the final census tally undercounts the actual total population. This phenomenon is called a "net undercount." See Joint Stips. ¶ 25; see also Tr. 1366-67. Additionally, even when there is no net undercount of the total population, the census may still undercount certain groups of people relative to other groups. See id. This is called a "net differential undercount" of a particular group. See Joint Stips. ¶ 25.

186. The Census Bureau has identified certain "hard-to-count" groups that, historically, have proved especially difficult to count completely and accurately. Joint Stips. ¶ 21. Racial and ethnic minorities, immigrant populations, and non-English speakers have historically been among the hardest groups to count. See id. ¶ 22.

187. The Census Bureau has developed a range of strategies to reach such hard-to-count populations. Id. ¶ 26. The strategies include targeted marketing and outreach efforts, partnerships with community organizations, deployment of field staff to follow up with individuals who do not respond, and employment of staff with foreign language skills. See id . For example, in the 2000 and 2010 censuses, the Census Bureau used public advertising campaigns that included paid media in over a dozen languages to reach hard-to-count immigrant communities and to improve their responsiveness. See id. ¶ 27. The Census Bureau also partnered with local businesses, faith-based groups, community organizations, elected officials, and ethnic organizations to improve the accuracy of the count. Id. ¶ 28.

188. Despite these efforts, net differential undercounts have persisted for certain hard-to-count groups. In the 1990 census, for example, Hispanics were undercounted by almost five percent. Id. ¶ 23. The 2010 census similarly undercounted Hispanic and other populations; in total, it undercounted more than 1.5 million Hispanic and African-American people. Id. ¶ 24.33

*5782. The Citizenship Question Will Cause a Differential Decline in Self-Response Rates

189. The central pillar of the Census Bureau's efforts to count everyone - and the means through which the majority of people are counted, AR 172 - is self-response to a questionnaire that the Census Bureau tries to send to every housing unit in the United States, see Joint Stips. ¶ 7. If there is net differential decline in self-response rates among a particular group (in other words, if the rate of self-response to the census questionnaire declines by a certain amount among a particular group, but not other groups) then that decline will, if left uncured, translate into a net differential undercount of that group (in other words, an undercount of that group that does not affect other groups).34 Plaintiffs have proved that the addition of a citizenship question will cause precisely that outcome with respect to noncitizen and Hispanic households. Moreover, with respect to the net differential decline in self-response rates among noncitizen households, Plaintiffs have also proved the likely amount of the decline. With respect to Hispanic households, by contrast, Plaintiffs have managed to prove only that there will be such a decline; the evidence is not sufficient to quantify the decline.

190. The Court begins, as the census does, with self-response to the census questionnaire. The evidence in the trial record overwhelmingly supports the conclusion that the addition of a citizenship question to the 2020 census will cause a significant net differential decline in self-response rates among noncitizen households (that is, households with at least one noncitizen). Significantly, that is the Census Bureau's own considered view. See, e.g. , Brown Memo at 39, 54. Indeed, several persuasive Census Bureau analyses support this position, and no evidence in the record - from Defendants or otherwise - contradicts it. Defendants do attack the Census Bureau's own analyses in one respect, discussed below, but the proposition that addition of the citizenship question will cause a net differential decline in self-response rates among noncitizen households is otherwise undisputed.

191. The Census Bureau's conclusions are spelled out in three memoranda. First, the Census Bureau's December 22 Memo summarized evidence that a citizenship question would cause a then-estimated 5.1% decline in self-response rates among noncitizens. See December 22 Memo, at AR 11639-40. It noted that "this evidence is consistent with citizenship questions being more sensitive for household with noncitizens," id. at AR 11640, a fact that is not in dispute, see PX-297 at RFA 70.

192. Second, the Census Bureau's January 19 Memo similarly concluded that addition of a citizenship question would reduce self-response rates. See January 19 Memo, at AR 1280. The Memo summarized "[t]hree distinct analyses" that "support the conclusion of an adverse impact on self-response" caused by the addition of a citizenship question. Id . First, data show that, on the ACS survey, Hispanic households *579are disproportionately less likely to respond to the citizenship question, whether responding by mail or online. Id. Second, a comparison of self-response rates for the 2000 census's long-form census questionnaire (which included a citizenship question) and its short-form census questionnaire (which did not) revealed that noncitizen households were 3.3% less likely than all-citizen households to respond to the long-form questionnaire. Id. A similar comparison of 2010 census self-response rates to 2010 ACS self-response rates (the latter of which included a citizenship question) produced a similar result: Noncitizen households were 5.1% less likely than all-citizen households to respond to the survey containing a citizenship question. See id. Based on these comparisons, the Memo noted, it was a "reasonable inference that a question on citizenship would lead to some decline in overall self-response" and "a larger decline in self-response for noncitizen households." Id. at AR 1281. Finally, the Memo analyzed the "breakoff rates" (the rate at which a respondent stops responding to the survey when he or she comes to a particular question) on the 2016 ACS internet survey. Those rates indicated that Hispanics were disproportionately likely to "breakoff" in their responses when they came to the citizenship question. See id .

193. Third, a comprehensive study by Census Bureau staff published on August 6, 2018 and referred to at trial as the Brown Memo (so named for its lead author) consolidated the existing data on the impact of a citizenship question. The Brown Memo also concluded that a citizenship question would disproportionately reduce noncitizens' self-response rates. See Brown Memo at 1, 54. The Brown Memo presented data illustrating that Hispanics and noncitizens are disproportionately unlikely to respond to a citizenship question. See id. at 7-9. The data also showed that those subpopulations became even less likely to respond to a citizenship question during the middle of this decade. See id. at 9-10 ("[T]hat sensitivity has increased in recent years.").

194. Whereas the January 19 Memo had predicted that addition of the citizenship question would cause a 5.1% differential decline in noncitizen household self-response rates, see January 19 Memo, at AR 1280, the Brown Memo updated that figure to 5.8% on the basis of more recent data, see Brown Memo at 39. Notably, it emphasized that the 5.8% estimate was still "conservative." Id. ; see also Tr. 900-01. It was conservative, the Memo explained, because the analysis supporting the estimate relied on ACS data, and the effect of a citizenship question on the ACS may have been muted by its presence among the large number of questions. See Brown Memo at 39; see also Tr. 87, 89, 901-02. A citizenship question on the shorter 2020 census questionnaire "will be more visible" and thus likely to produce a more pronounced effect. Brown Memo at 39. And changes in the macroenvironment since the ACS data was collected, including a higher "level of concern about using citizenship data for enforcement purposes," could also exacerbate the effects of adding a citizenship question. Id.

195. Separate and apart from its effects on self-response rates among noncitizen households, the Brown Memo supports the conclusion that adding a citizenship question to the 2020 census will disproportionately depress self-response rates among Hispanic households (some, but not all, of which are also noncitizen households). The Brown Memo showed that Hispanics were more than twice as likely as non-Hispanic whites to skip the citizenship question on the ACS and that the differential in such item nonresponse rates increased between 2013 and 2016.

*580Id. at 8-10. Other ACS questions did not produce the same differential effects. See id. And the Memo found that the citizenship-question breakoff rate for Hispanics on the ACS was eight times higher than the breakoff rate for non-Hispanic whites. See id. at 10; accord January 19 Memo, at AR 1281.

196. As the Census Bureau has observed, this differential breakoff effect is growing. The breakoff rate among Hispanics for the 2017 ACS citizenship question (which was not available in time to be incorporated into the Brown Memo's analysis) was twelve times higher than the breakoff rate for non-Hispanic whites. See AR 12757-62; Tr. 916. Moreover, the breakoff rate for Hispanics, but not for non-Hispanic whites, increased between 2016 and 2017 - suggesting that the effects of a citizenship question on Hispanic self-responses have been "increas[ing]." AR 12757-62; Tr. 916-17. The Census Bureau believes that "Hispanics are more sensitive to survey questions about citizenship than they were a few years ago"; non-Hispanic whites "are not." Census Bureau 30(b)(6) Dep. 366-69.

197. Defendants' expert, Dr. Abowd, credibly testified to the soundness of the Census Bureau's analyses and conclusion that adding a citizenship question to the 2020 census would result in a differential decline in self-response rates among noncitizen households. With regard to methodology, Dr. Abowd testified not only that the Brown Memo was "methodologically appropriate," but also that it "constitutes the best analysis that the Census Bureau can do of the consequences of adding the citizenship question to the 2020 census" given the available data. Tr. 897. With regard to conclusions, Dr. Abowd testified that both he and the Census Bureau agreed that adding a citizenship question to the 2020 census would lead to a lower self-response rate among noncitizen households. See id. at 881-82.35 Finally, Dr. Abowd agreed that "[t]he bulk of the evidence suggests that the citizenship question is likely to be responsible for the decline in self-response," and that 5.8% was a "conservative estimate" of the likely differential decline in self-response rates among noncitizen households if a citizenship question were added to the 2020 census questionnaire. Id. at 1352, 900-02.

198. Dr. Abowd testified that considerations beyond those mentioned in the Brown Memo further supported the view that the 5.8% estimate was "conservative." See id. at 944. For instance, he referred to the Census Bureau's Census Barriers, Attitudes, and Motivators Survey ("CBAMS"). See id. ; PX-662. The CBAMS found that, in 2018, only 67% of people said they were likely to respond to the 2020 census, as compared to the 86% who had said in 2008 they were likely to respond to the 2010 census. See PX-662, at 12. It noted that "[t]he citizenship question may be a major barrier" in part because people believed that the census's "purpose is to find undocumented immigrants." Id. at 43. Dr. Abowd testified that the increase in sensitivity to a citizenship question reflected in the CBAMS study "would not be captured in the 5.8 percentage point estimate that is based on data only up through 2016." Tr. 944-45; see also id. at 902, 916-17.

199. Testimony from at least three of Plaintiffs' expert witnesses bolsters the Census Bureau's and Dr. Abowd's conclusions about self-response rates. First, Dr. *581D. Sunshine Hillygus credibly and reliably testified that "noncitizens and Hispanics are differentially concerned about the confidentiality of a citizenship question" and, thus, "would be less likely to participate" in a survey that includes such a question. See id. at 50-51; see also id. at 57-58. She noted that this concern has increased in the last few years. Id. at 51-53. Notably, Dr. Hillygus testified that a citizenship question would be likely to affect the response rates of all Hispanics, "regardless of their own immigration or citizenship status." Id. at 51-52, 1404; see also PX-152; PX-662; PX-663. That testimony is supported by evidence showing that Hispanics who are citizens are disproportionately hesitant to engage with the government by seeking food stamps or health care out of fear that a family member could be deported. See Tr. 52-54, 57, 85-86.

200. Second, Dr. Matthew Barreto, "an expert in survey methodology, public opinion polling, and racial and ethnic politics," credibly testified that "the addition of a citizenship question ... in today's macro environment would result in reduced participation in Latino and immigrant communities in 2020." Id. at 589, 620-21. He based this conclusion on a review of existing social science literature and on the results of a public opinion survey that he designed and conducted. See id. at 620, 643-44. On the basis of that evidence, Dr. Barreto credibly concluded that Hispanic households would be substantially less willing to participate in the census if there were a citizenship question, regardless of whether they were given assurances that their responses would be kept confidential. Tr. 682-85; see also PX-670.36

201. Third, Dr. Jennifer L. Van Hook's expert analysis of 2017 ACS data demonstrates that nonresponse to the ACS citizenship question has continued to increase among Hispanics relative to other subgroups since 2013. See Docket No. 489-3 ("Van Hook Decl."), ¶¶ 69-71. By contrast, there has not been a significant increase in nonresponse rates for the citizenship question for other racial groups. See id. ¶ 70. On an absolute basis, nonresponse rates for the citizenship question for Hispanics have also increased since 2013. See id. ¶¶ 72-73.37

*582202. Amazingly, despite all of the foregoing evidence - much of it from Defendants' own expert witness and the Census Bureau itself - Defendants contend that Plaintiffs failed to prove that addition of a citizenship question will cause these differential declines in self-response rates. See Defs.' Post-Trial Br. 8-16; see, e.g., id. at 9-10, ¶¶ 94, 96. But that contention is without merit. First, it is based on a mischaracterization of the record evidence. For example, Defendants urge the Court to adopt a factual finding that, "[w]hile the balance of available evidence suggests that including a citizenship question on the 2020 Census could lead to a lower self-response rate in households that potentially contain a noncitizen, the magnitude of any such decline is unknown." Id. at 9, ¶ 93 (emphasis added and citation omitted). It goes without saying that the magnitude of any decline in self-response to the 2020 census questionnaire is, today, "unknown" (since the census has not yet occurred). But the weight of the evidence definitively shows the most that evidence about future events can ever show: a probable range of "magnitudes," all illustrating the overwhelming likelihood that the "magnitude" of the differential decline in self-responses among noncitizens and Hispanics will be quite high - in the case of noncitizen households, conservatively estimated to be 5.8% or higher.

203. Second, Defendants' argument fails because it relies heavily on misguided criticism of the Census Bureau's own research. For instance, Defendants argue that the Brown Memo "cannot assign causation to the citizenship question" because it is merely a "natural experiment," as opposed to "a randomized control trial," and because it "did not, and to a certain extent could not" control for every confounding variable. Defs.' Post-Trial Br. 10, ¶ 96. But the Brown Memo did conceive of, and control for, numerous potentially confounding variables in its analysis of the citizenship question's effect on self-response rates. See Brown Memo at 74-77 (Tables A13-A14); Tr. 1151. As Dr. Abowd explained, for example, the factors controlled for in that analysis were the "groups of questions that ... might plausibly be related to other sensitive questions for some subpopulation." Tr. 1150. That is, although it is true that no "natural experiment" could ever control for all possible confounding factors, this experiment did control for all plausible confounding factors associated with other questions on the ACS. See id ; see also id. at 1150-55. And, although Defendants argue that the Brown analysis did not control for the sheer length of the ACS, see Defs.' Post-Trial Br. 10, ¶ 96, the Brown analysis largely did control for that factor by controlling for household size, "which has the biggest effect on the number of questions that you have to answer in the [ACS]." Tr. 1152.

204. Finally, Defendants suggest that the Brown Memo is incomplete because it "could not account for the changing macro environment" and that it could be that the macroenvironment, rather than the citizenship question, explained why noncitizen households responded to the ACS at lower rates than all-citizen households. See Defs.' Post-Trial Br. 10, ¶ 96. But, as Dr. Abowd explained, the macroenvironment is "constant" or "almost constant" across the groups. Tr. 1153. That means that even though the kind of natural experiments described in the Brown Memo "can't make ... sophisticated controls for the macro environment," id. , any meaningful effects *583should be muted because the same macroenvironment affects all ACS respondents.

205. In sum, the trial evidence clearly shows, and certainly shows by a preponderance of the evidence, that the citizenship question will cause a significant differential decline in self-response rates among noncitizen households. Notably, even Defendants conceded at oral argument that there is "credible quantifiable evidence" that "the citizenship question could be expected to cause a decline in self-response." Tr. 1453.

206. More specifically, the Court finds that the addition of a citizenship question to the 2020 census will cause an incremental net differential decline in self-responses among noncitizen households of at least 5.8%. The Court further finds that that estimate is conservative and that the net differential decline could be much higher. Further, the evidence demonstrates, and the Court finds, that the citizenship question will also cause a significant decline in self-response rates among Hispanic households. Although it is harder to quantify the likely magnitude of that decline (or to isolate the decline from the citizenship question's effects on self-response rates among noncitizen households) based on the record here, the evidence of a decline in self-response rates among Hispanic households supports the overall conclusion that the 5.8% estimate captures only part of the citizenship question's differential effects.

3. NRFU Operations Will Not Cure the Differential Drop in Self-Response Rates

207. The Court turns next to the Census Bureau's procedures (referred to as Non-Response Follow-Up, or NRFU) for attempting to make up for the large number of households that do not self-respond to the census questionnaire. If a known household fails to self-respond, it is shifted into the Census Bureau's NRFU workload. See Joint Stips. ¶ 8. NRFU includes a range of operations designed to obtain data about those households that do not volunteer the information themselves: in-person visits to households by "enumerators"; use of administrative records; collection of information from "proxies," such as neighbors or landlords; and "imputation," a process through which the Census Bureau extrapolates data about households from supposedly comparable household data. See id. ¶¶ 9-12; Tr. 33-34; see also 83 Fed. Reg. 26643, 26648-49 (June 8, 2018) (admitted as PX-655). NRFU efforts in prior censuses have involved all of these methods, with the exception of a new proposed use of administrative records at one step in the process. See Census Bureau 30(b)(6) Dep. 400-01. The evidence demonstrates that each of NRFU's steps will replicate or exacerbate the effects of the net differential decline in self-response rates among noncitizen households.

208. Even before the addition of the citizenship question, the Census Bureau had been anticipating a somewhat larger NRFU workload for the 2020 Census. Rates of self-response to Census Bureau surveys have been in general decline, "as people are overloaded with requests for information and [are] increasingly concerned about sharing information." AR 162, 172. With the addition of the citizenship question and the corresponding decline in self-response rates it will cause, however, the Census Bureau now expects a previously unanticipated increase in NRFU cases. See January 3 Memo, at AR 5474; Brown Memo at 43. That is, the decline in self-response rates caused by the citizenship question will force the Census Bureau to "try to enumerate more people through nonresponse follow-up efforts." Tr. 950-52; see also January 19 Memo, at AR 1279-82. Moreover, because *584the decline in self-response rates will be disproportionately greater among noncitizens and Hispanics, the Census Bureau expects an increased use of NRFU operations in an effort to enumerate a disproportionate number of noncitizen and Hispanic households. See Brown Memo at 42-43.

209. The resulting increase in NRFU workload will be enormous. The Census Bureau estimates that nearly ten percent of all households "potentially contain at least one noncitizen." Brown Memo at 42. Based on this, it estimates that the addition of a citizenship question will cause approximately 2,090,000 additional households (approximately 6.5 million additional people) to go into its NRFU procedures, because of the citizenship question's effects on self-response among noncitizen households alone. See id.

210. The Census Bureau strives to maximize self-response rates - rather than relying on the collection of data through NRFU operations - for two reasons. First, NRFU operations are more expensive than self-response, so maximizing self-response reduces the costs of administering the census. See Tr. 33. Second, the data collected through self-response is more accurate and complete than the data collected through NRFU operations. See id. at 33-35, 292, 325. Accordingly, the Census Bureau places a high priority on obtaining self-responses from as many households as possible. See AR 163, 165.

211. Significantly, NRFU has not remedied net undercounts in prior censuses. For example, in prior censuses, the net undercounts of Hispanics were estimated at 1.54% (2010), 0.71% (2000), and 4.99% (1990) even after NRFU procedures. See PX-267, at 18 (Table 7); see also Tr. 1364-65. As Dr. Hillygus testified, these translated into differential undercounts of Hispanics, as compared to non-Hispanic whites, of 2.38% (2010), 1.84% (2000), and 4.31% (1990). See Tr. 95-97.

212. Moreover, historical data show that substantial post-NRFU undercounts can manifest in specific locations, including at the neighborhood level. See Tr. 407, 412-14, 416, 452-53. The 2010 Census, for example, omitted approximately 65,000 people in minority neighborhoods of Brooklyn and Queens, despite NRFU efforts. See id. at 452-53. That 2010 undercount involved an erroneous enumeration (that is, an overcount) of 8.4% in non-Hispanic white neighborhoods and an omission (that is, undercount) of over 10% in high-minority neighborhoods of Brooklyn. See id. at 412-413, 414, 452-53. Thus, although there was no net undercount in Brooklyn as a whole, the offsetting enumeration errors and NRFU failures yielded erroneous data at the neighborhood level. See id. at 412, 414.

213. The record shows that if a citizenship question is added to the 2020 census, NRFU procedures will fail to cure the resulting differential decline in self-response rates among noncitizen and Hispanic households. As the Court lays out in more detail below, each step of the NRFU process will fail to prevent such a decline from translating into a differential undercount of people who live in such households, and will likely even exacerbate the problem.

214. In the first place, the evidence shows that NRFU cannot - and does not even try to - fix undercounts caused by households leaving certain individual members off their questionnaire, a phenomenon that will be more common among noncitizen and Hispanic households. That is, when a household does self-respond, but omits one or more household members from its response, the Census Bureau simply assumes it has counted everyone at that address. NRFU does not even attempt to fix this problem, meaning that *585the uncounted household member will stay uncounted. See Tr. 1309-10; Census Bureau 30(b)(6) Dep. 459. This precise phenomenon has contributed to net undercounts of certain subpopulations in the past - including Hispanics. Id. at 1306; see Census Bureau 30(b)(6) Dep. 394. And indeed, the evidence shows that noncitizens and Hispanics are both disproportionately likely to be omitted from self-responses in this way, particularly if the citizenship question is added to the census. See Tr. 124-26; see also id. at 1308-10. Dr. Abowd testified that it is "fair" to say that NRFU "would not meaningfully address" any undercount caused by this type of omission. Id. at 1326. In fact, because such households would count as having self-responded, they would never enter the NRFU workload, and, for that matter, would not even count toward the 5.8% decline in self-response. That is, the phenomenon of household roster omissions helps explain both why the 5.8% figure is conservative and why NRFU will fall short.

215. Second, even where NRFU does attempt to address the decline in self-responses among noncitizen households, it is at least as likely to fail at that task as the decline in self-response is likely to occur in the first place. This is because many of the reasons that the citizenship question will cause a decline in self-response also apply to NRFU, and will also make NRFU less effective at remedying that decline. For example, to the extent that the macroenvironment will magnify the effects of the citizenship question on self-response, it will also render NRFU operations less effective among the subpopulations that are less likely to self-respond. See Census Bureau 30(b)(6) Dep. 314-15; Tr. 96, 100. As Dr. Abowd testified, the Census Bureau has not tested the efficacy of NRFU operations in the presence of a citizenship question. Tr. 1303. Plaintiffs, on the other hand, introduced persuasive evidence that NRFU operations will not succeed in remedying the differential decline in self-response caused by the addition of the citizenship question because each successive step of the NRFU process will reinforce or exacerbate the differential undercount of noncitizens and Hispanics. As the Court discusses below, this will happen in four primary ways: (1) noncitizens and Hispanics who do not self-respond to the census because of the presence of a citizenship question are similarly unlikely to respond (or to give a complete response) to in-person NRFU enumerators; (2) in some cases, NRFU will enumerate non-self-responding households using administrative records that, while the most accurate source of citizenship information, still tend to undercount noncitizens; (3) to the extent NRFU relies on "proxy" responses from third parties, those proxies are disproportionately unlikely to give information about noncitizen and Hispanic households and likely to underestimate their size when they do; and (4) imputation will reinforce or exacerbate the net differential undercount because it will extrapolate data about uncounted households - including a disproportionate number of noncitizen and Hispanic households - from a data set in which noncitizens and Hispanics are disproportionately underrepresented.

216. To begin, NRFU's first step - an in-person visit from a NRFU enumerator - is likely to disproportionately undercount noncitizens and Hispanics. As the Census Bureau itself acknowledges, households that refuse to self-respond to the census questionnaire because of the presence of a citizenship question are "particularly likely to refuse to respond in NRFU as well." March 1 Memo, at AR 1311. The Census Bureau's specific analysis of the effect of the citizenship question on the *586NRFU process bears this out: That analysis concluded that "[h]ouseholds deciding not to self-respond because of the citizenship question are likely to refuse to cooperate with enumerators coming to their door." Brown Memo at 41; see also id. at 42 n.19; Census Bureau 30(b)(6) Dep. 425; Tr. 1336-37. Defendants' own expert, Dr. Abowd, testified that the same considerations leading such households not to self-respond are likely to lead them not to respond to NRFU in-person enumerators. Tr. 1312. And as the authors of the Brown Memo concluded, given this resistance to in-person enumerators, the undercount attributable to a citizenship question "may not be avoidable ... by spending more money on fieldwork. Once a household decides not to cooperate, it may not be possible to obtain an accurate enumeration no matter how many times an enumerator knocks on their door." Brown Memo at 43 n.60. Based on the evidence, the Court finds that households that do not self-respond to the census questionnaire because of the citizenship question are similarly unlikely to respond to NRFU enumerators - or to give a complete and accurate accounting of the people who live in their households when they do. This step in NRFU will therefore only replicate the citizenship question's differential effects on self-response, thereby failing to counteract a differential undercount of people who live in noncitizen and Hispanic households.

217. The same will be true of what comes next for some households, after in-person NRFU attempts fail - the use of administrative records. After a NRFU enumerator's first visit to an address, if high-quality administrative records about that address are available, see AR 67 & n.4, the enumerator may consult those records to determine whether the address is vacant or should be deleted from the Master Address File or MAF, or even to enumerate the people who live there. See Tr. 1116, 1201-02, 1207-08; see also 83 Fed Reg. at 26649.38 But the use of administrative records in these ways will reinforce, rather than cure, the differential undercount of noncitizens and Hispanics.

218. First, although the evidence does not strongly suggest that it will disproportionately affect noncitizen or Hispanic households, using administrative records to mark addresses as vacant or for deletion from the MAF will negatively affect the quality of data obtained through NRFU procedures. When an address is marked as "vacant" or flagged for deletion from the MAF, it is "enumerated" as containing no people, and all further efforts to count people living there stop; no subsequent imputation is made to count people at that address. See Tr. 368. Put differently, "[i]mputation," the next step in NRFU, "is not required because you have essentially said there aren't any people there." Id . at 367. But, according to the Census Bureau's own limited studies, roughly twenty percent of addresses that administrative records suggest should be deleted or marked as vacant are actually occupied. See id. at 314; see also id. at 1199. Nor do the Census Bureau's future plans to address this error rate - which include adding *587an additional direct visit by an enumerator before marking an address "vacant" or "delete," id. at 1199-1200 - solve the problem. As a preliminary matter, it is not clear that the Court can even consider that possibility given that the parties' stipulations about NRFU procedures do not include such a step. See Joint Stips. ¶¶ 8-11. But it is not clear that the plans will reduce the error either. The Census Bureau has performed no testing of how effective the new procedures will be. See Tr. 1378-79. And when it attempted something similar in 2010 - that is, sending an enumerator to independently verify the status of any housing unit identified as vacant - the process still remained error-prone. See id. at 351-53.

219. Thus, the Court finds that the process of marking as vacant or deleting addresses from the MAF will result in the misidentification of occupied addresses as vacant or "should be deleted." This will undermine NRFU's ability to correct for any decline in the self-response rate on the 2020 census. Additionally, the Court finds that these errors will be particularly large in the 2020 census because the addition of the citizenship question and consequent decline in the self-response rates among noncitizen and Hispanic households will push more of these households into the NRFU process, where the errors will manifest. Although there is no evidence in the record to suggest that the errors introduced at this step will aggravate or ameliorate any net undercount of noncitizens or Hispanics, they will be one more mechanism through which the citizenship question will degrade the quality of resulting census data, by causing more households to be enumerated through this process, rather than through more accurate self-responses.

220. Whether and how administrative records will be used to enumerate non-self-responding households in NRFU is uncertain, as the procedure has not yet been approved by OMB, and the Census Bureau "hasn't made a decision yet about how it will process responses to the citizenship question alongside" those records. Tr. 1030. If administrative records are used for that purpose, however, they will reinforce the net undercount of people who live in noncitizen households and Hispanics. The Census Bureau has no data to show that using administrative records would cure a differential drop in self-response rates, Tr. 1340, and when asked whether there was evidence that "populations that are likely to see an increase in nonresponse due to the citizenship question can be successfully enumerated on a wide scale using administrative records," Dr. Abowd answered that "the administrative record actually shows that [the Census Bureau] concluded the opposite," id. Indeed, the evidence shows that, if the process is used, it will actually differentially undercount Hispanics and people who live in noncitizen households because the quality of administrative record data varies for different groups. Id. at 104. If such records are used, they will be used to enumerate only "a limited number of those households for which there is high quality administrative data about the household." Joint Stips. ¶ 9. Noncitizen and Hispanic households are less likely to be accurately represented in quality administrative records than other groups. Id. at 1340-41; Census Bureau 30(b)(6) Dep. 252-23, 389-91; Tr. 104. As a result, the Census Bureau expects that it will fail to link Hispanics to administrative records at a higher rate than non-Hispanic whites; that enumeration using administrative records will be less successful for noncitizens than for citizens; and that undocumented immigrants will be even harder to enumerate using administrative records because they are less likely to appear in such records at all.

*588See Tr. 1340-41; Census Bureau 30(b)(6) Dep. 389-91. Thus, although in a simple one-to-one comparison, the administrative records available to the Census Bureau are a more reliable source of accurate answers to questions about a person's citizenship status than survey questions, see AR 1285, the administrative records proposed to be used for this purpose would still tend to undercount people who live in noncitizen households. In any event, the Court declines to place much weight at all on a step that, Defendants admit, remains a hypothetical possibility rather than part of a finalized plan to address the effects of the citizenship question.

221. Third, the use of proxies at the next step of the NRFU process is also unlikely to cure the decline in self-response among noncitizens and Hispanic households. Indeed, as with other NFRU procedures, households that fail to self-respond because of the citizenship question will be relatively unlikely to be successfully enumerated through proxies. See Tr. 1342. For one thing, proxy responses are more likely to result in errors and omissions of household members than self-responses are, further degrading the quality of the resulting census data. See Census Bureau 30(b)(6) Dep. 382-83. For example, the Census Bureau's analysis of the 2010 Census found that proxy responses resulted in a correct enumeration only 70.2% of the time, as compared to 97.3% of the time for self-responding households. See January 19 Memo, at AR 1282 (citing PX-267 at 33, Table 21). For another, the Census Bureau has found that proxies generally "supply poor quality individual demographic and socioeconomic characteristic information about the person on behalf of whom they are responding." Brown Memo at 41, 42 (Table 12).

222. In fact, the evidence suggests that the use of proxies will reinforce or exacerbate the net differential undercount of people who live in noncitizen and Hispanic households attributable to the citizenship question. The record contains no evidence suggesting that households that fail to respond to the census because of a citizenship question will be enumerated through proxies as successfully as other non-responding households, Tr. 1342; to the contrary, the evidence suggests that households that fail to self-respond because of the citizenship question will be relatively unlikely to be successfully enumerated through proxies, even as compared to households that fail to self-respond for other reasons.

223. For instance, the Census Bureau's evidence shows that people who live in areas with higher percentages of noncitizen households are less likely to give proxy responses than people in other areas are. See Census Bureau 30(b)(6) Dep. 386. In other words, people who live in communities with high rates of noncitizens are disproportionately less likely to provide information about their neighbors to the government. Moreover, when proxies do answer, they are less likely to provide accurate information than self-responders are. See January 19 Memo, at AR 1282; Brown Memo at 41. Some proxies give incorrect information because they "have less information about the household than a member of the household [does]." Tr. 107. As Dr. Hillygus testified, proxy responders are especially likely to underestimate the size of noncitizen and Hispanic households because they do not know the true size of the household due to complexities in living arrangements. Id. at 110-11; see also id. at 1397-1400. And some proxies give incorrect information because they have an incentive to do so. For example, landlords concerned about violating the law might intentionally underreport the number of occupants in a household or fail to report residents lacking legal status.

*589See id. at 107-08, 336. And other proxies may choose not to reveal information for fear that it will cause negative consequences like deportation for their neighbors. See id . at 110-11; see also id . at 1398-1400. A preponderance of the evidence thus shows - and the Court finds - that the use of proxies in NRFU will systematically underestimate the size of noncitizen and Hispanic households.

224. Fourth, the final stage of the NRFU process - imputation - will also reinforce or exacerbate a differential undercount of people who live in noncitizen and Hispanic households. "Imputation" means, essentially, modeling or predicting information about the uncounted households based on the information already gathered from counted households. See id . at 1232, 1350-51. For the census, a household is "imputed" only if it remains uncounted after all the other NRFU steps. See id. at 1231, 1350. At that point, the Census Bureau imputes the number and characteristics of the people living in the household. See id. at 113-14. As practiced by the Census Bureau in NRFU operations, imputation has two components: "count imputation," which imputes the size of a household; and "whole-person imputation," which includes "count imputation" and imputation of all other characteristics to the people in the household. See id . at 113-14, 1193-94; January 19 Memo, at AR 1281. In each case, accurate imputation depends on an accurate starting point; "if there are errors in the data collected, those errors are then carried over into the imputation." Thompson Decl. ¶ 117; see e.g. , January 19 Memo, at AR 1282.

225. NRFU's imputation procedures will reinforce or exacerbate the net differential undercount of people who live in noncitizen and Hispanic households because the Census Bureau's imputation model incorrectly assumes that it is starting with accurate data. As Dr. Barreto credibly explained, when imputing characteristics from a group of counted (or "known") people to a group of unknown (or "missing") people, it matters whether the "missing" group is a random selection of the population or whether it is instead missing for a particular reason. See Tr. 702-03. If the "missing-ness" of a group is correlated with a particular characteristic, that will make it impossible to accurately impute characteristics from the known group to the missing group. See id . For example, if the group of "missing" households still uncounted after NRFU's first three steps is disproportionately composed of noncitizens and Hispanics compared to the known (i.e. , counted) households, then imputing the missing household characteristics from the known population (in which noncitizens and Hispanics are under represented) will not yield accurate data about the "missing" households (in which noncitizens and Hispanics are over represented). See also id. at 702-03, 1236-37.

226. That is precisely the problem here. For all the reasons explained above, when the Census Bureau performs its imputation calculations, noncitizen and Hispanics households will be underrepresented in the "counted" or "known" population and overrepresented in the "unknown" or "missing" population. See id. at 119, 1352-54, 1401; PX-400, at 3. Because the Census Bureau "do[es] imputation based on those self-responding ..., enumerated households," and because self-response to the Census is correlated with citizenship status (that is, citizens are more likely to self-respond to the census than noncitizens, as discussed above), the set of known households from which imputation proceeds will be disproportionately composed of all-citizen households. Tr. 1351-52; see Brown *590Memo at 44.39 Noncitizen and Hispanic households are therefore more likely to be counted using imputation. But because that imputation will extrapolate their numbers from an unrepresentative sample (which undercounts them), that imputation will lead to an erroneous under-enumeration of people who live in both noncitizen and Hispanic households. The Census Bureau knows that its imputation model will be biased in this way. See Tr. 114-19, 1353-54.

227. Dr. Abowd acknowledged that imputation "disadvantages hard-to-count subpopulations" such as noncitizens and households containing noncitizens. Id. at 1384-85. And Census Bureau data suggest that, historically, increased rates of imputation lead to undercounts in the imputed population. See PX-267, at 16-17 & Table 9. Additionally, the Census Bureau has historically treated household size as an "ignorable" characteristic, one that can be safely assumed to occur randomly throughout both the known and unknown populations. See Tr. 113-17; see, e.g. , PX-478 at 5-7. But the available data show that household size is not an ignorable trait. Because Hispanic and noncitizen households tend to be larger than other households, and because such households are underrepresented in the known sample (and overrepresented in the "missing" group), imputing household size from the known sample to the missing group leads to an undercount of the missing group. See Tr. 115-21. Imputing missing household figures from data that already undercount noncitizens and Hispanics, as the Census Bureau plans to do, will only extrapolate that undercount into the imputed data.

228. The Census Bureau has not yet finalized its imputation algorithm for the 2020 Census. See id. at. 1351. Dr. Abowd testified that the Census Bureau has set up an "expert panel" empowered to modify the imputation algorithm "if they can figure out a way to do so successfully," but "no such modification has been proposed to date." Id. at 1353. And, speaking more generally, Dr. Abowd testified that the Census Bureau "[does not] plan to modify the NRFU operation to address the citizenship question." Id. at 1357.

229. For all of these reasons, NRFU operations will fail to prevent the net decline in self-response rates among noncitizen (and likely Hispanic) households from translating into a net differential undercount of people who live in such households - instead, it will reinforce or exacerbate that decline.

230. In the face of Plaintiffs' considerable evidence that NRFU will fail to remedy the differential decline in self-response among Hispanic and noncitizen households - or, worse, even exacerbate the decline - Defendants offer no evidence to support their claim that NRFU will be adequate to the task. And indeed, the available evidence supports exactly the opposite conclusion. Where specific subpopulations have self-responded at relatively lower rates before, NRFU has failed to compensate for the difference, leading to net undercounts of those populations. As Plaintiffs' expert Dr. William P. O'Hare demonstrated based on his study of the last three censuses, for example, negative net differential self-response rates among demographic groups have reliably translated into net undercounts of those demographic groups despite the *591Census Bureau's NRFU operations . See Docket No. 507-1 ("Corr. O'Hare Aff."), ¶¶ 28-30, 38-39, 43-44. That is powerful evidence that NRFU is generally unable to prevent self-response declines from translating into net undercounts.

231. Dr. O'Hare opined further that declines in self-response rates cause net undercounts. See id. ¶¶ 47-55. In response, Defendants are quick to recite the old saw that correlation alone does not imply causation. See Defs.' Post-Trial Br. 16, ¶ 123. Dr. O'Hare recognized that, however, and was accordingly careful in his conclusions. And, as Dr. O'Hare correctly pointed out, a correlation of the strength and character that he described may be evidence of causation, even if it is incapable of establishing it beyond a reasonable doubt. See Corr. O'Hare Aff. ¶¶ 49-50.

232. The Court concludes just that: Dr. O'Hare's testimony provides affirmative evidence that self-response declines among specific subpopulations directly cause net undercounts of those subpopulations. For the purposes of this litigation, a preponderance of the evidence supports that conclusion. More importantly, however, Dr. O'Hare's testimony illustrates the historical inability of NRFU to prevent net undercounts of particular subpopulations in the presence of a decline in self-response rates.

233. Despite this evidence about the inadequacy of NRFU procedures, Defendants claim that NRFU efforts will be sufficient "to mitigate any decrease in the initial self-response rate." Defs.' Post-Trial Br. 16, ¶ 127. But Defendants offer no evidence to support their claim and, as noted above, the evidence strongly supports the opposite conclusion.

234. It is worth stepping back to view the evidence on this point as a whole. As is essentially undisputed, differential rates of self-response among different subpopulations are common, and the Census Bureau struggles to cure the defects caused by those differentially low self-response rates with its NRFU operations. For the 2020 census, the Census Bureau plans to add a question about citizenship that it knows will cause an additional, incremental differential decline in self-response rates in a defined subpopulation. But, Defendants argue, this will not result in a net undercount of that subpopulation, because its NRFU operations - which never work perfectly - will somehow work perfectly this time. Meanwhile, Plaintiffs have introduced overwhelming evidence (most of which is acknowledged, accepted, or generated by the Census Bureau itself) that, in this context, the Census Bureau's NRFU operations will instead work less well than ever - specifically with respect to the very people whose households will be differentially likely not to self-respond to the census questionnaire. Indeed, the evidence demonstrates that NRFU operations will simply replicate the same problems as the original attempt to obtain self-responses from those households.

235. Seen in that light, it is impossible to accept Defendants' interpretation of the facts. In the face of Plaintiffs' strong evidence that the citizenship question will cause a differential decline in self-response rates among noncitizen households, Defendants demand that Plaintiffs also rebut their unsupported assurances that the Census Bureau will figure out a way to fix the problem, even though it has never done so before. To the extent that Plaintiffs must carry that additional burden, they have done so, as their evidence about NRFU's inadequacies in this context is far more persuasive than Defendants' conclusory assertions that NRFU will suddenly work exactly as hoped. In any event, on the whole, a preponderance of the evidence establishes that the incremental net differential *592decline in self-response rates among noncitizen households caused by the citizenship question, and any similar decline among Hispanics, will remain uncured by NRFU, and will thus ripen into an incremental net differential undercount of the people who live in such households.

236. In sum, the Court finds that the addition of a citizenship question to the 2020 census will cause an incremental net decline in self-response rates of at least 5.8% among noncitizen households, and a significant but unquantified net decline in self-response rates among Hispanic households. The Census Bureau's NRFU operations will not remedy those declines, which means that they will translate into an incremental net differential undercount of people who live in such households in the 2020 census.

237. Admittedly, it is difficult to precisely quantify the exact size of the net differential undercounts attributable to the citizenship question. Significantly, though, that is because of the difficulty of quantifying the exact effects of the Census Bureau 's efforts to fix the problem, a subject about which there is frustratingly little quantitative evidence in the record. Starting with the conservative estimate of a 5.8% net decline in self-response rates among noncitizen households, the Court can find little justification in the record to depart from that estimate when arriving at a finding of the likely net undercount of people who live in noncitizen households. Indeed, as already discussed at great length, the evidence overwhelmingly suggests that NRFU operations will simply replicate all of the same effects on noncitizen response that will cause the decline in self-response in the first place. See supra ¶¶ 213-29. On the other side of the ledger, Defendants have offered no quantifiable evidence of their own to support, much less quantify, their assertions of NRFU's hoped-for curative effects.

238. The record does allow the Court to calculate a minimum likely net differential undercount of people who live in noncitizen households. If household size were distributed evenly across all households, both counted and uncounted, it would be possible to predict that an uncorrected 5.8% decline in self-response rates among noncitizen households would translate directly into a 5.8% net undercount of the people who live in those households. But the record evidence in these cases indicates that household size is not distributed equally among self-responding and non-self-responding households: instead, households that do not self-respond are likely to be larger than those that do. See Tr. 119-20, 733. The Court therefore finds that the 5.8% decline in self-response rates will translate into a net undercount of people who live in such households of at least 5.8%, and likely more. Providing further support for that conclusion is the disproportionate likelihood that noncitizen households that do self-respond will leave individuals off their questionnaires, contributing to a differential undercount of people who live in such households in a way not captured by the initial 5.8% estimate at all. The Court therefore finds that the addition of a citizenship question will cause an incremental differential net undercount of people who live in noncitizen households of approximately 5.8%, and likely more.

239. Quantifying the likely net undercount of Hispanics caused by the citizenship question is more difficult on the basis of the evidence in the record. Nevertheless, the Court finds that a preponderance of the evidence indicates that the citizenship question will cause a nonzero net undercount of Hispanics.

*593240. Defendants' objections to these factual findings rest primarily on Dr. Abowd's double-negative testimony that he has not seen any "credible quantitative data" that the Census Bureau's NRFU operations will not prevent net undercounts of noncitizen and Hispanic populations. See Tr. 1214. But Defendants' reliance on that testimony is ultimately unpersuasive, for two reasons. First, Dr. Abowd did not opine (and no other record evidence suggests) that NRFU operations will remedy any undercounts caused by the addition of a citizenship question to the 2020 census. Instead, he opined, "in a very careful way," only that he had not seen evidence sufficient to prove to his own standards that a net differential undercount would in fact result. See id. at 925-26, 1165-66.40 Even so, Dr. Abowd testified that the Census Bureau had not run the type of randomized controlled trial that would have met his own standard of "credible, quantitative evidence," but was nevertheless relying on the results of the "natural experiment" analyzed in the Brown Memo to plan for the 2020 census because, as he testified, the Census Bureau "believe[d] they are the best available data." Id. at 926; see also id. at 923-26.

241. Second, although Dr. Abowd's credibility, expertise, and dedication to public service impressed the Court in almost every respect, his opinion on this point does not shake the Court's confidence in its finding, by a preponderance of the evidence, that the addition of a citizenship question will cause a net differential undercount of noncitizens and Hispanics. For one thing, as Chief Scientist of the Census Bureau, his responsibilities are vastly different than those of a federal court, and his testimony and written analyses make clear that he and the Census Bureau insist (at least in the abstract) on a far greater degree of statistical confidence than that which applies in federal civil litigation.41 The Court's task is not to determine whether the evidence on the net differential undercounts caused by the citizenship question can satisfy the Census Bureau's high statistical standards. It is, instead, to determine whether Plaintiffs have proved by a preponderance of the evidence that the addition of a citizenship question will cause such undercounts. For the reasons stated above, the Court finds that Plaintiffs have done so.

4. Effects of the Citizenship Question on Apportionment Among and Within States

242. Next, Plaintiffs have also proved that the net differential undercount of people *594who live in noncitizen households will translate into several further concrete harms. First, the Court finds by a preponderance of the evidence that the addition of a citizenship question will cause or is likely to cause several jurisdictions to lose seats in the next congressional apportionment and that it will cause another set of jurisdictions to lose political representation in the next round of intrastate redistricting.

243. To begin, the Court finds that several states, including some that are Plaintiffs here and some in which NGO Plaintiffs' members reside, will lose at least one seat in the congressional reapportionment based on the 2020 census data. Plaintiffs' expert Dr. Christopher Warshaw modeled the effects of a net differential undercount of people who live in noncitizen households on congressional apportionment. See Docket No. 526-1 ("Warshaw Decl."). (Dr. Warshaw also independently modeled the effects of various net differential undercounts of people who live in noncitizen households and Hispanics together. See id. ). Using the Method of Equal Proportions, which Congress adopted as the apportionment method in 1941, Dr. Warshaw calculated that an incremental 5.8% net differential undercount of people who live in noncitizen households will make California "extremely likely" to lose a congressional seat that it would not lose otherwise. Id. ¶ 46; see id. at 23 (Table 6) & ¶¶ 42-46.

244. Dr. Warshaw's findings also support the conclusion that, in the event that the net differential undercount of people who live in noncitizen households reaches 10% - or if there is a mere 5.8% differential undercount both of people who live in noncitizen households and Hispanics - then Texas, Arizona, Florida, and Plaintiffs New York and Illinois will face a significant risk of an apportionment loss. See id. ¶¶ 46-47. As noted above, the Court cannot quantify exactly how much higher than 5.8% the noncitizen net differential undercount is likely to be and how high the Hispanic net differential undercount will be. See supra ¶¶ 238-39. But, based on the risks discussed above, the Court can say, and does find, that Texas, Arizona, Florida, and Plaintiffs New York and Illinois face a substantial risk of losing a seat in the next congressional reapportionment because of the addition of a citizenship question to the 2020 census.

245. The Court finds that Dr. Warshaw's calculations are credible and persuasive. As they are the most credible quantitative evidence in the record about the apportionment consequences of adding a citizenship question to the census questionnaire, the Court finds by a preponderance of the evidence that California residents face a certainly impending loss of representation in the House of Representatives. Similarly, Texas, Arizona, Florida, New York, and Illinois face a substantial risk of losing a seat. In other words, based on the facts as proved here by a preponderance of the evidence, the Court finds that residents of those states face a substantial risk of a loss of representation in the House of Representatives.

246. The Court finds further that the citizenship question will have similar effects on intra state apportionment. States - including Plaintiffs here - rely on federal decennial census data to carry out their own intra state redistricting. See, e.g. , Del. Const. art. 2, § 2A ; Iowa Const. art. III, § 34 ; Md. Code Ann., Elec. Law § 8-701; Mass. Const. amend. art. CI, §§ 1-2; Minn. Const. art. 4, §§ 2 - 3 ; Minn. Stat. Ann. § 600.18 ; N.J. Const. art. 4, § 2 ¶¶ 1, 3 ; N.Y. Const. art. III, §§ 4 - 5 &

*5955-a ;42 Va. Code Ann. § 30-265 ; Wash. Rev. Code § 44.05.090 ; see also Georgia v. Ashcroft , 539 U.S. 461, 488 n.2, 123 S.Ct. 2498, 156 L.Ed.2d 428 (2003) ("When the decennial census numbers are released, States must redistrict to account for any changes or shifts in population."); Department of Commerce , 525 U.S. at 334, 119 S.Ct. 765 ("States use the population numbers generated by the federal decennial census for federal congressional redistricting."). The addition of a citizenship question on the census will cause some jurisdictions and their residents to lose political power in that process as well.

247. Dr. Warshaw analyzed the impact of the citizenship question on intrastate redistricting, and credibly found that a mere two percent differential undercount of people who live in noncitizen households will lower the population enumerations, and statewide population shares, of several jurisdictions that are home to a disproportionate share of their states' populations living in noncitizen households. See Warshaw Decl. 28 (Table 8) & ¶¶ 53-55, 57-59. New York City is a prime example. New York City contains approximately forty-three percent of the total state population, but approximately seventy-one percent of the state's noncitizen population. Docket No. 504-1 ("Breitbart Aff.") ¶ 12; see also Docket No. 504-2 ("Supp. Breitbart Aff."). Dr. Warshaw calculated that if the citizenship question causes a mere two percent net differential undercount of people who live in noncitizen households, that will lower the statewide population shares of Phoenix, Arizona; Los Angeles County, California; Monterey County, California; Miami, Florida; Chicago, Illinois; Prince George's County, Maryland; New York City; Columbus, Ohio; Philadelphia, Pennsylvania; Pittsburgh, Pennsylvania; Central Falls, Rhode Island; Providence, Rhode Island; Cameron County, Texas; El Paso County, Texas; Hidalgo County, Texas; and Seattle, Washington. Warshaw Decl. 28 (Table 8) & ¶¶ 53-55, 57-59. The effect will be particularly pronounced for Plaintiffs Central Falls and Providence, Rhode Island; Cameron, Hidalgo, and El Paso Counties, Texas; Phoenix, Arizona; Miami, Florida; and New York City. See id. ¶¶ 54-55, 59.43

248. Any net differential undercount of people who live in noncitizen households, and especially a net differential undercount of 5.8%, will dilute the political power of such jurisdictions. Similarly, the people who live in those jurisdictions will suffer a corresponding decrease in political power.

*596249. The Court also finds, based on Dr. Warshaw's credible calculations, that Plaintiff Colorado will suffer a net undercount of its total population of at least 0.7%, an estimate Dr. Warshaw calculated using the conservative projection of an estimated 5.8% net differential undercount of people who live in noncitizen households. See Warshaw Decl. 19 (Table 5). Furthermore, because Colorado is home to a significant population of people who live in noncitizen households, any net differential undercount of that population greater than zero will cause Colorado's enumerated population to be lower than it otherwise would be. See, e.g. , PX-324 (illustrating that if there is a 2% undercount of noncitizens in Colorado, the state's population will be undercounted by 0.2%). Similarly, because Colorado is home to a significant population of Hispanics, any net differential undercount of that population greater than zero will cause Colorado's enumerated population to be lower than it otherwise would be.

5. Effects of the Citizenship Question on Funding to, and Within, States

250. A net undercount of people who live in noncitizen households will also cause states (and their residents) to lose access to federal funding from domestic financial assistance programs that allocate funding based on census-tied geographic formulas. See Docket No. 508-1 ("Reamer Decl."), ¶¶ 15-17, 83. A large number of federal domestic financial assistance programs rely on census data to allocate money. In fiscal year 2016, for example, at least 320 such programs allocated about $900 billion using census-derived data. See id. ¶ 9. Plaintiffs' expert witness Dr. Andrew Reamer calculated the effects of a net differential undercount of people who live in noncitizen households on several such programs. Of the programs Dr. Reamer analyzed, eighteen are "state-share" programs, which rely in whole or part on the state's share of the total U.S. population. Id. ¶¶ 10, 16-17.44 The rest are programs that use the Federal Medical Assistance Percentage ("FMAP") reimbursement formula. See id.45 These programs - and many others, including those that rely on decennial census data less directly, see id. ¶¶ 26-29 - are sensitive to changes in the decennial census count. Dr. Reamer calculated that a net differential undercount of people who live in noncitizen households46 *597and Hispanic populations of as little as two percent - much lower than the net differential undercount would likely be - will cause Plaintiffs New York and New Jersey, as well as California, Texas, Florida, Nevada, and Hawaii, to lose funding under the state-share programs, and would cause Arizona, Texas, Florida, Nevada, and Hawaii to lose funding under the FMAP programs. See id. ¶¶ 16-17, 33, 35 & 16, 17, 20, 23, 27 (Tables). Larger net undercounts would, naturally, lead to correspondingly larger losses. Id. ; see also id. ¶ 19.

251. The Court finds Dr. Reamer's testimony to be credible, and his analysis persuasive. Accordingly, the Court finds that even under an almost implausibly conservative projection of the net differential undercount of people who live in noncitizen households, Plaintiffs New York and New Jersey, along with Arizona, California, Texas, Florida, Nevada, and Hawaii will lose some amount of federal funding as a result of the addition of the citizenship question. More specifically, the Court finds that Plaintiffs New York and New Jersey, along with California, Texas, Florida, Nevada, and Hawaii, would lose funding under the WIC, Social Services Block Grants, and Title I Grants to LEAs programs. See Reamer Decl. ¶¶ 46-47, 51-52, 61-62. Those are merely illustrative; as Dr. Reamer testified, those states would lose funding from other state-share programs as well. See Tr. 517-18.

252. The Court further finds, based on Dr. Reamer's testimony, that a two percent net differential undercount of people who live in noncitizen households will cause Plaintiffs Illinois, Massachusetts, Maryland, Washington, and the District of Columbia to lose funding under the Title I LEA Grant program and the Social Services Block Grant Program. See Reamer Decl. 17 (Table), 20 (Table) & ¶¶ 51-52, 61-62. A net differential undercount of people who live in noncitizen households of at least two percent will also cause Plaintiffs Illinois and Washington to lose Medicaid funds, and Plaintiffs Oregon, New Mexico, and Washington to lose CHIP funds. Id. at 23, 27 (Tables) & ¶¶ 70-71, 81-82.

253. In addition to the state-share programs Dr. Reamer testified about, Plaintiffs have proved that even a tiny net differential undercount of people who live in noncitizen households will cause several Plaintiffs to lose funds from federal programs that distribute resources on the basis of census-derived data, including Community-Based Child Abuse Prevention ("CBCAP") Grants, Older Americans Act ("OAA") Grants for State and Community Programs on Aging, Title II, Part A and Title IV, Part A funding under the Every Student Succeeds Act, Temporary Assistance for Needy Families ("TANF") funding, Low-Income Home Energy Assistance, Program ("LIHEAP") funding, and Community Services Block Grants ("CSBG"). Docket No. 498-12 ("Haney Aff."), ¶¶ 5-8; Docket No. 498-14 ("Harmon Aff."), ¶¶ 10-13, 17; Docket No. 498-5 ("Franklin Aff."), ¶¶ 6-10; Docket No. 501-1 ("Tiema-Massie Aff."), ¶ 11. Some such programs require states to use census-derived data to distribute funding to City and County Plaintiffs, including the Victims of Crime Act program, TANF, LIHEAP, the WIOA program, and CSBG. Franklin Aff. ¶¶ 6-10; Tiema-Massie Aff. ¶ 11. The City and County Plaintiffs receive funds under these programs based on their relative share of the relevant population within a state. For instance, states are required to distribute TANF, LIHEAP, WIOA, and CSBG funds to localities based in part on the number of low-income *598individuals who reside in the jurisdiction. See Franklin Aff. ¶¶ 7-8, 10; Tiema-Massie Aff. ¶ 11.

254. Similarly, many federal funding programs provide direct funding to localities based on census-derived information, including the Community Development Block Grant ("CDBG"), Emergency Solutions Grant ("ESG") program, and the HOME Investment Partnerships Program. See Docket No. 498-7 ("Freedman Aff."), ¶¶ 7, 10, 12. These programs provide funding to cities and counties based at least in part on such jurisdictions' share of the overall population count relative to other metropolitan areas and share of the population in poverty. Id.

255. Dr. Warshaw's testimony shows that under any plausible net differential undercount scenario resulting from the addition of a citizenship question, nearly all Plaintiff Cities and Counties will lose population shares relative to their states. See Warshaw Decl. 28 (Table 8) & ¶¶ 59-61. Those cities and counties - specifically, Cameron, Hidalgo, and El Paso Counties, Texas; Monterey County in California; and Providence and Central Falls in Rhode Island, id. at 26 (Table 7) - will lose funds under these programs, whether the funds are routed through state governments or distributed from the federal government directly.

256. The Court also finds - based on uncontradicted evidence in the record - that Plaintiff MRNY has identified several members by name who reside in New York City and who benefit from the federal funding programs that Plaintiffs have shown are tied specifically to federal census data. See Docket No. 503-1 ("Altschuler Decl."), ¶¶ 24-30; see also Docket No. 503-2 ("Supp. Altschuler Decl."); Tr. 472. MRNY members Julissa Bisono and Diana Zarumeno are both residents of Queens County, New York, whose children attend public schools that receive Title I funding. Altschuler Decl. ¶¶ 25-26; Supp. Altschuler Decl. ¶¶ 15-16. MRNY member Maria Hernandez is a resident of Kings County, New York, whose child attends a public school that receives Title I funding. Altschuler Decl. ¶ 27; Supp. Altschuler Decl. ¶ 17. MRNY member Lorena Mendez is a resident of Kings County whose child attends a Head Start program. Altschuler Decl. ¶ 28; Supp. Altschuler Decl. ¶ 18. MRNY member Perla Lopez and MRNY member Yatziri Tovar live in Queens County, New York, and Bronx County, New York, respectively. Altschuler Decl. ¶¶ 29-30; Supp. Altschuler Decl. ¶¶ 19-20. Altschuler also identified an unnamed MRNY member who is a U.S. citizen and a resident of Long Island, New York. Altschuler Decl. ¶ 16; Supp. Altschuler Decl. ¶ 11.

257. The Court also finds, based on uncontradicted testimony and undisputed documentary evidence in the record, that ADC has members residing in all fifty states and in the District of Columbia, including 172 in Arizona; 1,441 in California; 1,296 in the District of Columbia; 551 in Florida; 437 in Illinois; 612 in Maryland; 819 in New York; 341 in Ohio; 1,341 in Pennsylvania; 30 in Rhode Island; 408 in Texas; and 186 in Washington State. Docket No. 498-16 ("Khalaf Decl."), ¶¶ 34-35; see also Docket No. 498-17 ("Supp. Khalaf Decl."), ¶ 7; Tr. 286. For example, ADC members Dr. Souhail Toubia, Dr. Diane Shammas, and George Majeed Khoury reside in California; Dr. Debbie AlMontaser resides in New York; Shatha Atiya resides in Florida; Dr. Safa Rifka and Dr. Doo'a Taha reside in the District of Columbia; and Abed Awad resides in New Jersey. Khalaf Aff. ¶ 31.

258. Finally, to the extent relevant here, the Court finds that Plaintiff NYIC has members who benefit from census-tied *599funding programs. NYIC member Chhaya Community Development Corporation ("Chhaya") receives funding through the Community Development Block Grant program. Docket No. 498-19 ("Plum Aff."), at ¶ 6; see also Docket No. 498-20 ("Supp. Plum Aff."). NYIC members Family Health Centers at NYU Langone, Little Sisters of the Assumption Family Health Services ("LSA"), Korean Community Services of Metropolitan New York, and Planned Parenthood of New York City all receive funding through Medicaid to provide community health services. Id. ¶ 7. NYIC member Chinese-American Planning Council receives funding through the WIOA for education and training services for job-seekers. Id. ¶ 8.

6. Effects of the Citizenship Question on the Quality and Accuracy of Census Data

259. Next, the Court finds that the addition of a citizenship question to the 2020 census will harm the quality of the resulting census data regardless of whether it also leads to a net differential undercount of people who live in noncitizen and Hispanic households. Much of that decline will be attributable to the fact that, because of the decline in self-response rates, more enumerations will be conducted through NRFU efforts. March 1 Memo, at AR 1311. As all agree, NRFU generates lower quality data than self-responses - in large part because it relies more heavily on proxies and imputation. Tr. 33-35; January 19 Memo, at AR 1281. There is essentially no dispute about this point. Dr. Abowd - Defendants' expert - "consistently characterized data produced by lower self-response rates as being less accurate" in his testimony, Tr. 882; see March 1 Memo, at AR 1311, and described how that inaccuracy would hamper the work of demographers and policymakers at all levels of government, see Tr. 1222-23.

260. Credible testimony confirms that the citizenship question and consequent decline in self-response rates are likely to harm the resulting data in several ways. For instance, information about subgroups that comprise a jurisdiction - called local-level "characteristic data" - will decline in quality, even if the total population count within that jurisdiction is accurate. Tr. 302-04. This will be true regardless of whether NRFU is able to remedy the decline in self-response rates for the jurisdiction as a whole. See id. at 1221-23.

261. In fact, NRFU operations may actually make the problem worse. The Census Bureau's own analysis concluded that enumeration errors are more common in NRFU because NRFU data "are much more likely to be collected from a proxy rather than a household member," and proxies have "less accurate information" about the household than self-responders. January 19 Memo, at AR 1282. In particular (and as discussed above), proxies result in correct enumerations only about seventy percent of the time, compared to ninety-seven percent for self-responses. Id. And proxies "supply poor quality individual demographic and socioeconomic characteristic information about the person on behalf of whom they are responding." Brown Memo at 41. As Dr. Jarmin put it, the accuracy of NRFU "is less than self-response" and, within NRFU, "proxy response" is less accurate still. Jarmin Dep. 308.

262. Dr. Abowd testified that, whatever else happens as a result of the citizenship question, "gross omissions" - people left off self-response, responses to in-person NRFU enumerators, and proxy responses - will increase. Tr. 1221. In Dr. Abowd's view, this will harm the quality of the data, regardless of what happens to the overall count. Id. at 1222. Indeed, even *600where a decline in self-response does not lead to an overall net undercount, it will create inaccuracies in subgroup data - particularly at the local level - that can be quite serious in and of themselves. See Tr. 309, 351-54.

263. Several Governmental Plaintiffs proved that they rely on accurate data to perform essential governmental functions. New York City, for example, makes important decisions about how to allocate public services in reliance on demographic data derived from the census, as when its Department of Education redraws school zone boundary lines, Tr. 305-06; when its Department of Health deploys resources based on its best understanding of the age, race, and Hispanic origin characteristics within particular communities, id. at 307-08; and when the Mayor's Office of Immigrant Affairs distributes English-language services based on its understanding of where the highest concentration of limited-English-proficient ("LEP") populations live, id. at 307. Dr. Salvo also testified that New York City is expecting a forty-six percent increase in its sixty-five-and-over population by 2040, and is currently attempting to project where and when that demographic change will be felt so that it can design and deploy appropriate infrastructure and physical accommodations. See id . at 356-57. A decline in the quality of decennial census data will degrade the City's ability to make and implement such policies.

7. Secretary Ross's Decision Has Caused Plaintiffs to Divert Resources

264. Secretary Ross's decision to add a citizenship question to the census will cause, and has already has caused, another harm to Plaintiffs: the diversion of precious resources. The NGO Plaintiffs - NYIC, MRNY, ADC/ADCRI, and CASA - have already diverted significant resources from their organizational missions and other priorities to address the effects of a citizenship question. Each of the NGO Plaintiffs is deeply committed to a laudable mission of increasing political participation, promoting civic engagement, and advancing the interests of immigrant communities, especially immigrant communities of color.

265. Plaintiff NYIC is an "umbrella policy and advocacy organization for nearly 200 groups in New York State." Docket No. 489-1 ("Choi Decl."), ¶ 2; see also Docket No. 489-2 ("Supp. Choi Decl."); Tr. 21-22. NYIC aims to "unite immigrants, members, and allies so that all New Yorkers can thrive," is devoted to "advanc[ing] the interests of New York's diverse immigrant communities," and "advocates for laws, policies, and programs that lead to justice and opportunity for all immigrant groups." Choi Decl. ¶ 3. NYIC has a "fundamental interest in ensuring as complete and accurate a Decennial Census as possible," id. ¶ 6, partly because its member organizations receive funding through census-tied federal funding programs, id. , and partly because the communities its member organizations serve will only receive the full political representation to which they are entitled if the people in those communities are fully counted, id. at 8. For that reason, NYIC has committed itself to ensuring a complete and accurate census count since at least 2010. During the 2010 cycle, NYIC engaged in widespread efforts to encourage participation, including by coordinating public service announcements in sixty-nine newspapers (and in twenty-four languages), and by holding press briefings with elected officials. Id. ¶ 9.

266. NYIC has already started similar efforts with respect to the 2020 census. In March 2018, for instance, NYIC helped *601launch New York Counts 2020, a coalition of New York stakeholders committed to a "fair and complete" census count. Id. ¶ 10. More broadly, NYIC has been investing its organizational resources in outreach, education, and advocacy to increase participation in the 2020 census. Id. ¶ 11. Before the addition of the citizenship question was announced, NYIC planned to spend approximately $625,000 on such education and outreach efforts over a three-year period leading up to the 2020 census. Id. ¶ 16. NYIC testifies that it has increased that spending by approximately sixty percent "as a result of the decision to add a citizenship question," and will now spend approximately $1 million on its efforts. Id. ¶¶ 16-17; see Docket No. 498-19 ("Plum Decl."), ¶ 14 (stating that the extra spending "represents an increase of approximately 60% over what the organization would have spent in the absence of a citizenship question"); see also Tr. 286. Of that additional amount (roughly $375,000), NYIC has already spent about $93,000 in funds it would not have spent absent the addition of the citizenship question. Choi Decl. ¶¶ 16-17.

267. The Court also finds, based on the undisputed testimony of NYIC's Vice President of Policy Elizabeth Plum, that NYIC has diverted, and will continue to divert, resources from its organizational mission because of the citizenship question. As Plum testified, NYIC "was undertaking a study and publication on adult English literacy and workforce development, which examines the critical role of English language acquisition in integrating immigrants into the workforce and preparing them to earn higher wages," but "that project has been postponed indefinitely because of the resources required to perform additional Census outreach and education work." Plum Decl. ¶ 23. Plum also testified that "NYIC and some of its member organizations will have to divert resources that would have been spent on education and outreach efforts to increase Census response rates among immigrant communities of color towards addressing the heightened fear generated by the citizenship question." Id.

268. Notably, Defendants dispute none of this. They merely contend that the cause of NYIC's increased spending is not the citizenship question itself, but the macroenvironment of fear and distrust of government. Defs' Post-Trial Br. 39-42, ¶¶ 261, 272. The Court is not persuaded. Plaintiffs' testimony credibly makes clear that NYIC increased its expenditures "as a result" of the addition of the citizenship question - a statement made all the more credible and persuasive given that the macroenvironment prevailing at the time NYIC made its initial funding decisions was similar to the macroenvironment at the time it made the decision to increase those expenditures. Choi Decl. ¶ 17; see Tr. 616-17, 942-44. The Court has no trouble concluding by a preponderance of the evidence that NYIC has incurred (and will continue to incur) these extra expenses, and has diverted resources away from its organizational mission, because of the citizenship question and not because of Defendants' proposed alternative causes.

269. Plaintiff MRNY is a nonprofit membership organization with offices and service centers in Brooklyn, Queens, Staten Island, Suffolk County, and White Plains, New York. See Altschuler Decl. ¶ 2. MRNY's mission is to "build the power of immigrant and working-class communities." Id. ¶ 3. MRNY has an "ongoing commitment to promoting engagement in the Decennial Census among its members and constituents." Id. ¶ 7. During the 2010 cycle, MRNY spent about $150,000 and more than one thousand personnel hours on its census education and outreach efforts. Id. ¶ 8. MRNY is conducting similar outreach *602and education programs this time around, and has already begun creating informational resources and training staff members to conduct outreach and encourage census response, "particularly" among Spanish-speaking communities. Id. ¶ 20.

270. Daniel Altschuler, MRNY's Director of Civic Engagement and Research, id. ¶ 1, testified that the organization "will be forced to expend more resources than initially anticipated to try to reduce the negative effect" of the citizenship question among "the immigrant communities of color it serves." Id. ¶ 19. More precisely, MRNY "anticipates expending at least double the amount on 2020 Census education and outreach" than it did for the 2010 census. Id. Altschuler testified that "[b]ecause of the need to increase the time and money spent on Census outreach due to the addition of the citizenship question, MRNY will need to divert resources from other areas critical to its mission[,] including civic engagement and community organizing on other issues." Id. ¶ 21. Indeed, MRNY has already done so. Id. Separate and apart from the diversion of those resources, MRNY has diverted resources towards participating in this lawsuit. Id. ¶ 22.

271. Once again, Defendants contest very little of Altschuler's credible testimony about MRNY's activities, focusing only on the causal connection between the citizenship question and MRNY's additional expenditures and noting that MRNY "acknowledges that there is a general increased fear due to the Trump Administration." Defs.' Post-Trial Br. 39 (alterations and internal quotation marks omitted). But MRNY has submitted evidence of a causal connection between the citizenship question itself and the diversion of its resources in the form of Altschuler's credible testimony, and Defendants offer nothing at all in rebuttal. Once again, the Court has no trouble concluding by a preponderance of the evidence that MRNY has doubled its 2020 census expenditures because of the addition of the citizenship question.

272. Plaintiffs ADC and ADCRI were founded by Senator James G. Abourezk - the first Arab American to serve in the United States Senate - in 1980 and 1981, respectively. Khalaf Decl. ¶¶ 4-5. ADC is a "civil rights membership organization that is committed to defending and promoting the rights and liberties of Arab Americans and other persons of Arab heritage." Id. ¶ 6. ADC and ADCRI have long track records of census-related work. For example, ADC has served on Census Bureau advisory committees "in numerous capacities" since the 1980s, and has conducted census-related campaign and policy initiatives since the 2000 census cycle. Id. ¶ 13. ADC and ADCRI have increased their planned spending on 2020 census education and outreach by $150,000 compared to 2010, "largely" because of "the presence of the citizenship question." Id. ¶ 28. As with MRNY, Defendants do not dispute any of these facts, except to object that ADC has not "analyze[d] any incremental increase in expenditures due to the citizenship question." Defs.' Post-Trial Br. 39, ¶ 260. Again, however, Defendants offer no evidence to rebut Plaintiffs' credible testimony that precisely such an incremental increase is occurring, and the Court finds that it is.

273. Plaintiff CASA is a nonprofit membership organization headquartered in Maryland, with additional offices in Virginia and Pennsylvania. Docket No. 498-3 ("Escobar Decl."), at ¶ 4. CASA is the largest membership-based immigrants' rights organization in the mid-Atlantic region. See id. CASA's mission is "to create a more just society by increasing the power of and improving the quality of life of low-income immigrant communities."

*603Id. ¶ 5. CASA offers social, health, education, job training, employment, and legal services to such communities, serving "nearly 20,000" people each year through its physical offices alone. Id. Part of CASA's work in service of its mission is "promoting engagement in the Decennial Census among its members, constituents, and communities." Id. ¶ 7. George Escobar, the organization's Chief of Programs and Services, id. ¶ 1, testified that "[m]ember participation in the Decennial Census advances CASA's mission by increasing the political power of low-income immigrant communities and improving quality of life for those communities through increased population-driven government funding," id. ¶ 7.

274. Given its thirty-year history working with immigrant communities, CASA has "consistently been a 'go-to' organizational partner" for outreach and education efforts concerning the census. Id. ¶ 8. Because of the addition of a citizenship question, CASA is now "diverting [its] limited resources in an effort to encourage participation in the Decennial Census." Id. ¶ 15. Indeed, CASA is planning a "massive response" to mitigate the effects of the citizenship question, id. ¶ 25, and "will have to reorganize its communication team and reassign staff to Census outreach and education to a level not previously anticipated," id. ¶ 26. Given the unanticipated nature of those expenses, CASA will have to fund these efforts through "other sources" - "perhaps including CASA reserves" - and additional volunteers. Id. CASA has already begun some of these efforts. Id. ¶ 27. Defendants, for their part, nowhere dispute (or even discuss) any of these facts. Instead, Defendants level the same highly general objection to CASA's account as with the other NGO Plaintiffs, namely that Plaintiffs have not "shown any analysis to account for the incremental increase due to the citizenship question." Defs.' Post-Trial Br. 39, ¶ 259.47 The Court is unpersuaded by Defendants' objection to CASA's lack of detail in accounting for the precise incremental increase in expenditures which, by definition, have not happened yet, and finds - by a preponderance of the evidence - that CASA will divert a significant portion of its organizational resources because of the addition of the citizenship question.

275. The Court also finds, based on the undisputed record evidence, that Plaintiffs New York City and the City of Chicago have diverted or will divert resources in an attempt to mitigate the effects of the citizenship question. New York City had originally allocated $4.3 million to its efforts to increase participation in the 2020 census, and then - after Secretary Ross announced his decision - increased that funding to $5.5 million. Tr. 426-29. Plaintiffs also introduced uncontroverted evidence that the City of Chicago will expend additional resources to combat the citizenship question's effects on self-response among immigrant communities in Chicago. See Docket No. 488-1 ("Rodriguez Aff."), at ¶ 12; see also Tr. 11-12, 21.

*604C. Conclusions of Law Related to Standing

The Court turns, then, to its conclusions of law with respect to standing. Plaintiffs advance at least five distinct theories of how they have been, or will be, injured due to the addition of a citizenship question on the 2020 census, namely: (1) diminished political representation, both between and within states; (2) loss in government funds, again both between and within states; (3) harm to the sovereign interests of state and local governments caused by degradation of the census data upon which they rely; (4) diversion of resources; and (5) loss of privacy. The Court begins by addressing the question of certain NGO Plaintiffs' standing to pursue claims based on any of those theories on behalf of their individual members (in addition to any standing they may have to pursue such claims in their own right). The Court then explains its conclusions as to whether each of these forms of injury is legally cognizable and, if so, whether Plaintiffs proved by a preponderance of the evidence that they have been, or will be, injured in that manner. As the Court will explain, it concludes that all five forms of injury are legally cognizable and that, for all but one of the theories - namely, the loss of privacy - at least some Plaintiffs proved by a preponderance that they have suffered, or will suffer, injury in fact sufficient to support standing. The Court then turns to whether Plaintiffs proved that those forms of injury are fairly traceable to Secretary Ross's decision to add the citizenship question to the 2020 census and whether they are redressable by a favorable decision. Answering both questions in the affirmative, the Court concludes that most, if not all, Plaintiffs have Article III standing to bring the claims in these cases.

The Court notes that, aside from challenging each of Plaintiffs' theories of injury on "traceability" grounds, Defendants make only limited objections to each individual theory of injury. Specifically, Defendants challenge Plaintiffs' apportionment-loss and funding-loss theories only on the ground that they are insufficiently "imminent," Defs.' Post-Trial Br. 67-68, ¶¶ 11-14; the resource-expenditure theory only on the ground that Plaintiffs' expenditures do not qualify as legally cognizable injuries-in-fact, id. at 69-70, ¶¶15-19; and the data-degradation theory only on the ground that it is not a sufficiently "concrete" and "tangible" injury for purposes of Article III, id. at 70, ¶¶20-21. Defendants do not explicitly address Plaintiffs' theory of harm to their privacy interests anywhere in their Proposed Conclusions of Law. The Court cannot ignore the omitted objections given its independent obligation to assess its jurisdiction. But it is worth noting that Defendants themselves do not appear to believe that any of Plaintiffs' injuries are not redressable or - apart from their ambitious objections to traceability, discussed below - fairly traceable to the citizenship question.

1. Associational Standing

Before turning to Plaintiffs' theories of injury, however, the Court briefly addresses the issue of associational standing - namely, whether any of the NGO Plaintiffs have standing to bring claims on behalf of their individual members (in addition to any standing they may have to pursue such claims in their own right). An organization has "associational" standing to bring claims on behalf of its members if "(a) its members would otherwise have standing to sue in their own right; (b) the interests it seeks to protect are germane to the organization's purpose; and (c) neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit."

*605Food and Commercial Workers v. Brown Grp. , 517 U.S. 544, 553, 116 S.Ct. 1529, 134 L.Ed.2d 758 (1996) (internal quotation marks omitted). The third of those requirements is only a prudential one - that is, it is not an element of Article III's jurisdictional limitations on the power of the federal courts. See id. at 554-57, 116 S.Ct. 1529.

Applying those standards here, the Court concludes - subject to its broader conclusions regarding standing below - that three of the NGO Plaintiffs, NYIC, MRNY, and ADC, have proved that they have associational standing to seek relief on behalf of certain of their members. The second and third prongs of the analysis can be swiftly addressed. Defendants make no argument with respect to the third, non-jurisdictional prong and, thus, have waived the issue. Cf. Stolt-Nielsen S.A. v. AnimalFeeds Int'l Corp. , 559 U.S. 662, 670 n.2, 130 S.Ct. 1758, 176 L.Ed.2d 605 (2010). In any event, concerns of "administrative convenience and efficiency" favor associational standing, as neither the claims asserted nor the relief requested in this litigation call for significant participation by individual members; at most, the claims call for proof of their residence, but that can be readily established without direct participation. Food and Commercial Workers , 517 U.S. at 556-57, 116 S.Ct. 1529. As for the second prong of the analysis, which Defendants also fail to contest, the Second Circuit has explained that an interest is "germane" to an organization's purpose if the lawsuit would "reasonably tend to further the general interests that individual members sought to vindicate in joining the association and ... bears a reasonable connection to the association's knowledge and experience." Bldg. & Constr. Trades Council of Buffalo, New York & Vicinity v. Downtown Dev., Inc. , 448 F.3d 138, 149 (2d Cir. 2006). Here, as discussed above, ADC's, MRNY's, and NYIC's missions involve obtaining government benefits for their communities, including - indeed, expressly by means of - ensuring a fair and accurate census count of those communities. Thus, the second prong of the associational standing test is satisfied.

That leaves the first - and only disputed - prong of the analysis: whether the NGO Plaintiffs' members would otherwise have standing to sue in their own right. Although proof of a mere "statistical probability that some of [an organization's] members are threatened with concrete injury" is not enough to satisfy the first prong of associational standing, an organization can meet the first prong by offering "specific allegations" (along, at this stage, with proof) "establishing that at least one identified member had suffered or would suffer harm." Summers v. Earth Island Institute , 555 U.S. 488, 497-98, 129 S.Ct. 1142, 173 L.Ed.2d 1 (2009). Asserting that "a vague reference to unidentified members does not confer associational standing on an organization," Defendants contend that the NGO Plaintiffs have "failed to identify any member who has standing to sue in his or her own right." Defs.' Post-Trial Br. 71, ¶¶ 25-26. While that is true of CASA, see generally Escobar Decl., it is not true of NYIC, MRNY, or ADC. NYIC has identified specific members who receive funds from federal programs that distribute those funds on the basis of census data. See Recitation of Facts ¶ 258. Similarly, MRNY has identified specific members who live in New York (and, more specifically, certain counties within the state) whose children attend Head Start programs or public schools that receive Title I funding. See Recitation of Facts ¶ 256. And ADC has identified specific members who reside in California, Florida, New York, the District of Columbia, and New Jersey. See Recitation of Facts ¶ 257. More generally, there is evidence that *606ADC has members residing in all fifty states. Id. That is sufficient to establish that those members, although unnamed, would have standing to the extent that standing depends only on the facts of their existence and residence in a particular jurisdiction. As will be discussed below, that is true with respect to some (albeit not all) of the theories of injury at issue here.48

In short, three of the NGO Plaintiffs have established - in addition to whatever standing they may have in their own right - that they have standing to the same extent that certain of their individual members would have standing. More specifically, NYIC has standing to the extent that its members who receive funds from census-tied programs would have standing. MRNY has standing to the extent that its individual members residing in New York State generally, and Queens, Brooklyn, the Bronx, and Long Island specifically, would have standing and to the extent that its individual members whose children attend Head Start programs or public schools that receive Title I funding would have standing. And ADC has standing to the extent that its individual members residing in all fifty states and the District of Columbia - and certainly those residing in California, New York, Pennsylvania, Texas, Florida, Rhode Island, Washington State, Arizona, Illinois, Maryland, New Jersey, and the District of Columbia - would have standing.

2. Injury in Fact

With that, the Court turns to Plaintiffs' five theories of injury: (1) loss of political representation, both between states (in congressional reapportionment) and within states (in redistricting); (2) loss of federal funds, also both between and within states; (3) harm to important sovereign interests caused by degradation of the census data on which state and local governments rely; (4) injury to organizations and local governments through the diversion of, and strain inflicted upon, organizational resources; and (5) infringement of privacy interests in the information collected by *607the census. As noted, the Court concludes that all five forms of injury are legally cognizable and that, as to four of the five - namely, all except the privacy-infringement theory - at least some Plaintiffs have proved by a preponderance of the evidence that they have suffered, or will suffer, injury in fact sufficient to support standing.

a. Diminished Political Representation

First, Plaintiffs have proved that several states are likely to lose one or more seats in the next round of congressional redistricting if the citizenship question is added to the census. See Recitation of Facts ¶ 243-45. The Supreme Court has squarely held that the loss of a seat or seats in the House of Representatives "undoubtedly satisfies the injury-in-fact requirement of Article III standing" because of the dilution of political power that results from such an apportionment loss. Dep't of Commerce , 525 U.S. at 331, 119 S.Ct. 765 ; accord Carey v. Klutznick , 637 F.2d 834, 836-38 (2d Cir. 1980) ; cf. Utah v. Evans , 536 U.S. 452, 458, 122 S.Ct. 2191, 153 L.Ed.2d 453 (2002). Further, although the census is still months away, such an injury is sufficiently "imminent" to invoke federal-court jurisdiction now. See Dep't of Commerce , 525 U.S. at 327, 332, 119 S.Ct. 765 (finding threatened vote dilution because of census modifications sufficiently "imminent" in two lawsuits brought twenty-five months before the census date).

In particular, Plaintiffs have proved that California's prospective loss of a seat in the House of Representatives is "certainly impending." See Recitation of Facts ¶¶ 243, 245. And although California is not a Plaintiff here, ADC is and, as discussed, it has individual members who reside in California. See id. ¶ 257. Those individual members' "expected loss of a Representative to the United States Congress undoubtedly satisfies the injury-in-fact requirement of Article III standing." Dep't of Commerce , 525 U.S. at 331, 119 S.Ct. 765.49 Plaintiffs have also proved that New York and Illinois face a "substantial risk" that they will lose at least one seat in the next Congressional *608reapportionment because of the citizenship question's addition to the 2020 Census. See Recitation of Facts ¶¶ 243, 245. New York and Illinois are Plaintiffs here, and thus have standing to seek a remedy for that injury in their own right. Cf. Evans , 536 U.S. 452, 122 S.Ct. 2191. Additionally, that provides an independent basis for ADC and MRNY to seek relief, as ADC has individual members who reside in New York and Illinois, see Recitation of Facts ¶ 257, and MRNY has individual members who reside in New York, see id. ¶ 256. ADC's individual members who reside in Texas, Arizona, and Florida, see id. ¶ 257, likewise face a substantial risk of lost representation in the U.S. House of Representatives.

A closer question is whether Plaintiffs have also proved that any of the NGO Plaintiffs' members will suffer an Article III injury in fact in the form of lost representation in intra state redistricting carried out on the basis of the federal decennial census. Intrastate vote dilution plainly qualifies as an injury in fact for purposes of Article III. Dep't of Commerce , 525 U.S. at 332-33, 119 S.Ct. 765 ; Carey , 637 F.2d at 838. In Department of Commerce , for example, the Supreme Court held - given the fact that certain counties "were substantially likely to lose population" under the Census Bureau's plan - that residents of those counties had satisfied Article III's injury-in-fact requirement. 525 U.S. at 334, 119 S.Ct. 765. In other words, all the Court required was proof that (1) certain states relied on federal decennial census data for intrastate redistricting, (2) voters in certain counties in those states were "substantially likely ... to suffer vote dilution as a result of the [Census Bureau's] plan," and (3) plaintiffs were among the voters who lived in those counties in those states. Id. at 332-34, 119 S.Ct. 765 (internal quotation marks omitted). As that language suggests, however, the Supreme Court has tended to describe the injury in the intra state vote-dilution context as affecting only eligible voters. Here, Plaintiffs have proved that several of the NGO Plaintiffs' individual members reside in counties that will lose statewide population shares because of the citizenship question, but the record is silent as to whether those members are also eligible voters. In this instance, the Court concludes that the interests of avoiding an unnecessary holding on a delicate constitutional question outweigh even the powerful interests favoring resolution of all open legal issues in this Opinion. See Ashwander , 297 U.S. at 347, 56 S.Ct. 466 (Brandeis, J., concurring). The Court therefore declines to address whether the facts proved by Plaintiffs are legally sufficient to establish that any of the NGO Plaintiffs' members will suffer an Article III injury when, at a minimum, they lose political representation in the next intrastate redistricting.

b. Loss of Government Funds

Second, given the Court's factual findings, many Plaintiffs have proved that they will suffer a loss of funding from federal programs that distribute such funding on the basis of census data. Such a monetary loss is a classic form of Article III injury in fact. See Carey , 637 F.2d at 838 (holding that "citizens who challenge a census undercount on the basis ... that improper enumeration will result in loss of funds to their city have established ... an injury" for purposes of standing); accord City of Detroit v. Franklin , 4 F.3d 1367, 1374-75 (6th Cir. 1993) ; City of Philadelphia v. Klutznick , 503 F.Supp. 663, 671 (E.D. Pa. 1980) ; City of Camden v. Plotkin , 466 F.Supp. 44, 47-51 (D.N.J. 1978). More specifically, a state or locality that proves that it will lose funds under federal revenue-sharing programs satisfies Article *609III's injury-in-fact requirement. See Carey , 637 F.2d at 838 ("New York City and New York State ... have standing as recipients of federal funds under revenue sharing."). So too, an individual who proves that he or she will suffer a loss of federal benefits has adequately proved an Article III injury. See id. ("The individual plaintiffs in this case have alleged concrete harm in the form of ... decreased federal funds flowing to their city and state, thus establishing their standing.").

Applying those principles here, the Court concludes as follows:

• Plaintiffs Illinois, Massachusetts, Maryland, New Jersey, New Mexico, New York, Oregon, Washington State, and the District of Columbia have proved that if the net undercount of noncitizens attributable to the citizenship question is as low as two percent - far lower than the Court has found to be the best estimate - they will lose funds from several federal programs. See Recitation of Facts ¶¶ 251-52. On that basis, the Court concludes that those Plaintiffs face "certainly impending" injuries.

• Plaintiffs have also proved that (1) MRNY's individual members who reside in New York and (2) ADC's individual members who reside in California, Texas, Florida, Nevada, and Hawaii, and in Plaintiff States New York and New Jersey, face a "certainly impending" Article III injury for the same reasons. See Recitation of Facts ¶¶ 256-67.

• Additionally, Plaintiffs have proved that MRNY's individual members who reside in New York and benefit from Title I and Head Start funds will suffer an individualized harm that is "certainly impending," in light of its propensity to occur in even the most implausibly low noncitizen net undercount scenarios. See Recitation of Facts ¶ 256.

• Finally, Plaintiffs have proved that NYIC's members Chhaya, LSA, Korean Community Services of Metropolitan New York, Planned Parenthood of New York City, and Chinese-American Planning Council all receive funding through programs that allocate funds to states based on census data. See Recitation of Facts ¶ 258. Given the net undercount scenarios that the Court has found to be likely, those organizations have proved that they face a substantial risk of an Article III injury in the form of lost funding.

Defendants argue that, even if Plaintiffs have proved these losses are likely to occur, they do not count as Article III injuries because they may be "offset" by gains that turn up elsewhere in the federal funding scheme. See Tr. 506; Defs.' Post-Trial Br. 34-36, ¶¶ 220-38. But "the fact that an injury may be outweighed by other benefits, while often sufficient to defeat a claim for damages, does not negate standing." Denney v. Deutsche Bank AG , 443 F.3d 253, 265 (2d Cir. 2006) ; see also Texas v. United States , 809 F.3d 134, 155-56 (5th Cir. 2015), aff'd by an equally divided Court , --- U.S. ----, 136 S.Ct. 2271, 195 L.Ed.2d 638 (2016) (mem.); NCAA v. Governor of N.J. , 730 F.3d 208, 223 (3d Cir. 2013) ("A plaintiff does not lose standing to challenge an otherwise injurious action simply because he may also derive some benefit from it. Our standing analysis is not an accounting exercise ...."), abrogated on other grounds by Murphy v. NCAA , --- U.S. ----, 138 S.Ct. 1461, 200 L.Ed.2d 854 (2018) ; Alaska Elec. Pension Fund v. Bank of Am. Corp. , 175 F.Supp.3d 44, 53 (S.D.N.Y. 2016).

*610Plaintiff Colorado will also suffer an injury for a related reason: It will lose the ability to spend funds because its own state constitution limits year-on-year increases in expenditures to a function of the state's population growth as determined by federal census data. The Colorado "Taxpayer's Bill of Rights," ratified into the Colorado Constitution, limits the "maximum annual percentage change in state fiscal year spending" to "inflation plus the percentage change in state population in the prior calendar year, adjusted for revenue changes approved by voters after 1991," and provides that "[p]opulation shall be determined" for that purpose "by annual federal census estimates and such number shall be adjusted every decade to match the federal census." Colo. Const. art. X, § 20 (7)(a); see Colo. Rev. Stat. § 24-77-103(1)(c)(III) (providing for a formula to recalculate the percentage change each year on the basis of new federal census estimates). Whether characterized as a loss in funding, or a loss in the ability to spend for the general welfare of its residents (and, thus, an infringement on Colorado's sovereign interests), Colorado will suffer an Article III injury if its population is undercounted by even the smallest amount. Given the Court's findings as to the likely net undercount of Colorado's population, see Recitation of Facts ¶ 249, the Court concludes that Colorado faces a "certainly impending" injury traceable to the addition of the citizenship question.

In sum, given the remarkably low net undercount of noncitizens that would prompt the foregoing losses of funding, Governmental Plaintiffs Colorado, Illinois, Massachusetts, Maryland, New Jersey, New Mexico, New York, Oregon, Washington State, and the District of Columbia; and NGO Plaintiffs ADC, MRNY, and NYIC have established an injury in fact that is "certainly impending." At a minimum, there is no doubt that these Plaintiffs have demonstrated a "substantial risk" that they will suffer such injuries. In either case, these Plaintiffs have satisfied Article III's injury-in-fact requirement.

c. Harm to the Quality and Accuracy of Data

Next, the Governmental Plaintiffs proved that they will suffer injury in fact from the degradation in data quality that would occur if the citizenship question appears on the 2020 census. At the outset, there is no reasonable dispute that Plaintiffs proved by a preponderance of the evidence that addition of the citizenship question would result in that harm. Indeed, the evidence at trial was undisputed that, regardless of how successful NRFU operations are in remedying a net differential undercount due to a differential decline in self-response rates, the addition of the citizenship question will result in harm to the quality of census data. First, as noted above, that was the original position of the Census Bureau in connection with its review of DOJ's request. See Recitation of Facts ¶¶ 8, 19, 28-30, 34. Second, Defendants own expert, Dr. Abowd, agreed, testifying that the addition of a citizenship question would harm the overall quality of 2020 census data regardless of any net undercount scenario. See Tr. 882, 952-53, 1221-22, 1251. And third, Plaintiffs' experts testified credibly in the same manner. Tr. 302-04. Additionally, Dr. Salvo, the Director of the New York City Department of City Planning's Population Division, explained credibly that the degradation in quality of the data would harm New York City's ability to allocate educational and public health resources efficiently and effectively. See Recitation of Facts ¶ 263.50

*611Crucially, these harms will occur whether or not there is a net undercount - meaning that this theory of injury does not depend on the causal chain of events connecting the decline in self-response rates among noncitizen households to a net differential undercount of people who live in such households.

Understandably, then, Defendants raise no objections in their post-trial filings to the imminence, traceability, or redressability of this harm. See Defs.' Post-Trial Br. 70, ¶¶ 20-21. Instead, the principal dispute between the parties is whether a degradation in the quality of census data is a legally cognizable harm. Compare id., with Pls.' Proposed Conclusions ¶¶ 57-59. The Court agrees with Plaintiffs that it is. For starters, the Supreme Court has consistently held that the "inability to obtain information" is a cognizable Article III injury. FEC v. Akins , 524 U.S. 11, 21, 118 S.Ct. 1777, 141 L.Ed.2d 10 (1998) ; Pub. Citizen v. U.S. Dep't of Justice , 491 U.S. 440, 449, 109 S.Ct. 2558, 105 L.Ed.2d 377 (1989) ("[R]efusal to permit appellants to scrutinize the ABA Committee's activities to the extent [the Federal Advisory Committee Act] allows constitutes a sufficiently distinct injury to provide standing to sue."); id. ("Our decisions interpreting the Freedom of Information Act have never suggested that those requesting information under it need show more than that they sought and were denied specific agency records."). If the inability to obtain information is a cognizable form of injury for Article III purposes, it follows a fortiori that the inability to obtain accurate information would be as well. After all, there is no interest in obtaining false or faulty information.

To be sure, many of these cases involved statutory entitlements to certain information - the classic example of such an entitlement (although, interestingly, the example least discussed in the context of Article III standing) being the Freedom of Information Act. That is no objection to the conclusion that the Supreme Court has recognized the denial of information as an Article III injury, however, because if such an injury were not already "concrete" enough for Article III purposes, Congress could not make it so. As the Supreme Court recently clarified, "Congress' role in identifying and elevating intangible harms" does not allow it to grant standing on the basis of pure statutory violations - instead, "Article III standing requires a concrete injury even in the context of a statutory violation." Spokeo , 136 S.Ct. at 1540. Thus, if the claims of informational injury discussed in the cases amounted to nothing more than "bare procedural violation[s], divorced from any concrete harm," they would not "satisfy the injury-in-fact requirement of Article III," id. - but they are more than that, so they do.

Similarly, a state that relies on the information provided by the federal government under an existing statutory arrangement suffers a sufficiently "concrete" and "particularized" injury for purposes of Article III when the federal government degrades the quality of that information. States are sovereign entities with sovereign interests in the making and enforcement of their own laws. See *612Alfred L. Snapp & Son, Inc. v. Puerto Rico ex rel. Barez , 458 U.S. 592, 601, 102 S.Ct. 3260, 73 L.Ed.2d 995 (1982) ; cf. Maryland v. King , 567 U.S. 1301, 133 S.Ct. 1, 3, 183 L.Ed.2d 667 (2012) (Roberts, C.J., in chambers) (concluding that Maryland suffered an injury to its "law enforcement and public safety interests" from a lower-court order preventing the state from utilizing DNA samples for law enforcement purposes pursuant to a state statute). But they frequently do so in collaboration with, or in reliance on, the federal government - such is the genius of the federal system, which has historically embraced various creative models of "cooperative federalism." See, e.g., New York v. United States , 505 U.S. 144, 167-69, 112 S.Ct. 2408, 120 L.Ed.2d 120 (1992) ; Hodel v. Va. Surface Mining & Reclamation Assn., Inc. , 452 U.S. 264, 286-89, 101 S.Ct. 2352, 69 L.Ed.2d 1 (1981). Most relevant here, states have long relied on federal decennial census data for countless sovereign purposes, and many of the State Plaintiffs here even require the use of such data by law; in some instances, it is written into their state constitutions.

The most noteworthy examples of this reliance are the State Plaintiffs that mandate the use of federal decennial census data to apportion state representatives. See, e.g. , Recitation of Facts ¶ 246; see also Georgia , 539 U.S. at 488 n.2, 123 S.Ct. 2498 ; Dep't of Commerce , 525 U.S. at 333 n.4, 334, 119 S.Ct. 765. But state reliance on federal census data for sovereign purposes goes well beyond that, as the following examples - ranging from the profound to the mundane - make plain:

• States often seek to apportion governmental expenses equitably among local governments, for example, by requiring each county to contribute in proportion to its share of population as calculated by the latest federal decennial census. See, e.g. , Colo. Rev. Stat. § 20-1-208 (requiring counties to contribute towards the salaries of employees in Colorado district attorneys' offices according to the counties' population share, as determined in the "last preceding decennial census" of the district in which each county sits); Conn. Gen. Stat. Ann. § 7-338 (requiring that the expenses of a charter commission for a new metropolitan fire, sewer, or water district be apportioned among "each town, city or borough" according to its proportion of the district's total population, "as determined by the last-preceding federal census").

• Other states provide for direct state aid to local governmental units on a per capita basis, relying on federal decennial census data to ensure a fair distribution of resources. See, e.g. , 30 Ill. Comp. Stat. 115/2(a) (requiring monthly allocations of the Illinois "Local Government Redistributive Fund" and "Income Tax Surcharge Local Government Distributive Fund" in proportion to cities' and counties' population as determined by federal decennial census data); Minn. Stat. Ann. § 260.821(1)(b) (requiring that support grants to Indian tribes be apportioned, in part, on the basis of "the ratio of the tribe's on-reservation population to the state's total on-reservation population," as determined by the "most recent federal census data"); R.I. Gen. Laws §§ 23-18.9-1, 23-18.9-3 (requiring that funds appropriated as grants in aid of local refuse disposal services be distributed according to a community's share of the statewide population, according to federal census data); N.Y. State Fin. Law § 54(2) (McKinney) (providing that *613each fiscal year, "there shall be apportioned and paid to the several counties, cities, towns and villages, from moneys appropriated by the state, for the support of local government" amounts in proportion to their "population"); id. § 54(1)(a)(1) (defining "population" to mean "the population as shown by the latest preceding decennial federal census" or a "special population census").

• Some states also redistribute state tax receipts to cities on the basis of each city's population share. See, e.g. , Iowa Code Ann. § 312.3(2)(a) (providing that the state treasurer shall, on the first day of each month, "[a]pportion among the cities of the state, in the ratio which the population of each city, as shown by the latest available federal census, bears to the total population of all such cities in the state, the percentage of the road use tax funds which is credited to the street construction fund of the cities"); N.M. Stat. Ann. § 7-1-6.26(C) (providing that counties shall receive a share of the "county government road fund" calculated in part based on the county's population "as shown by the most recent federal decennial census"); Or. Rev. Stat. § 221.770 (requiring that certain liquor revenues be apportioned among Oregon's cities in part based on their population as determined by federal census data).

• North Carolina apportions state support to community colleges in part based on a formula that takes into account ratios of county and area populations as determined by the "latest United States census." N.C. Gen. Stat. § 115D-31(a)(3).

• Pennsylvania sets the maximum salary for the mayor of any city with a population greater than 15,000 at "$500 per every thousand residents per year as determined by the most recent census data provided by the United States Census Bureau." 11 Pa. Cons. Stat. § 11208(a), (b). It also sets the maximum "tapping fee" that a sewer or water authority may charge a property owner who connects to the authority's sewer or water system as a function of the average household size "as established by the most recent census data provided by the United States Census Bureau." 53 Pa. Cons. Stat. § 5607(d)(24) (i)(C)(V)(e).

• Some states more generally define "population" for the purpose of their laws to mean population as calculated in the most recent federal decennial census. See, e.g. , Iowa Code Ann. § 9F.6 ("Whenever the population of any county, township or city is referred to in any law of this state, it shall be determined by the last preceding certified federal census unless otherwise provided."); N.Y. Gen. Constr. Law § 37-b (McKinney) ("The term population when used in relation to this state ... shall, unless otherwise provided in relation to such use, mean population as shown by the latest federal census published as a final population count by the United States bureau of the census."); Va. Code Ann. § 1-235 (" 'Population' or 'inhabitants' means with reference to any county, city, town, political subdivision of the Commonwealth or any combination thereof, the natural persons in such county, city, town, political subdivision or combination as shown by the unadjusted United States decennial census ....").

*614Meanwhile, it is, of course, the federal government's job to collect and distribute accurate federal decennial census data. See U.S. Const. art. I, § 2, cl. 3 ; see also Utah , 536 U.S. at 478, 122 S.Ct. 2191 (explaining that the Framers had a "strong constitutional interest in [the] accuracy" of the census); Wisconsin , 517 U.S. at 20, 116 S.Ct. 1091 (holding that the conduct of the census must bear a "reasonable relationship to the accomplishment of an actual enumeration of the population, keeping in mind the constitutional purpose of the census," namely, obtaining an accurate count of the population in each state); Pub. L. No. 105-119, § 209(a)(6), 111 Stat. at 2481 ("Congress finds that ... [i]t is essential that the decennial enumeration of the population be as accurate as possible, consistent with the Constitution and laws of the United States."). When the federal government degrades the quality of that data, it therefore inflicts a cognizable injury on the sovereign interests of reliant states.51

An example may be helpful in illustrating the point. Suppose a state were to premise certain of its policies on a person's lawful presence in the United States - for example, suppose that it chose to deny certain benefits to undocumented immigrants or required its law-enforcement officials to inquire into the immigration status of any person detained in state custody for any reason. "The accepted way" for states "to perform [such] status checks" - and surely the most reliable - is to contact the DHS' Immigration and Customs Enforcement ("ICE"), the federal agency that accepts and responds to such inquiries from interested states. Arizona v. United States , 567 U.S. 387, 411, 132 S.Ct. 2492, 183 L.Ed.2d 351 (2012). Now suppose that ICE were to degrade the quality of its data set, thereby undermining its usefulness to the state as a tool for implementing its policy priorities. If this hypothetical state were to challenge the decisions causing the degradation in immigration-status data, the federal agency could certainly defend its actions on the grounds that they were lawful. But could it seriously deny that the state had suffered a cognizable injury for purposes of standing? Surely not.

Indeed, ample case law supports the proposition that a state has a strong sovereign interest in conducting its own policy, the burdening of which causes an injury in fact for Article III purposes. One such sovereign interest is a state's "exercise of sovereign power over individuals and entities within [its] jurisdiction - this involves the power to create and enforce a legal code, both civil and criminal." Alfred L. Snapp & Son , 458 U.S. at 601, 102 S.Ct. 3260. Another such sovereign interest - which, in light of the frequent prohibition on parens patriae suits against the federal government, Massachusetts v. Mellon , 262 U.S. 447, 485-86, 43 S.Ct. 597, 67 L.Ed. 1078 (1923), is "distinct from ... the general well-being of its residents" - is a state's "interest in securing observance of the terms under which it participates in the federal system," Alfred L. Snapp & Son , 458 U.S. at 607-08, 102 S.Ct. 3260 ; cf. Maine v. Taylor , 477 U.S. 131, 137, 106 S.Ct. 2440, 91 L.Ed.2d 110 (1986) ("[A] State clearly has a legitimate interest in the continued enforceability of its own statutes."); Diamond v. Charles , 476 U.S. 54, 65, 106 S.Ct. 1697, 90 L.Ed.2d 48 (1986) ("Because the State alone is entitled to *615create a legal code, only the State has the kind of 'direct stake' ... in defending the standards embodied in that code.").

The Fifth Circuit's decision in Texas v. United States , 809 F.3d 134 (5th Cir. 2015), aff'd by an equally divided Court , --- U.S. ----, 136 S.Ct. 2271, 195 L.Ed.2d 638 (2016), is instructive on this front. In that case, Texas led a coalition of states in a challenge to the Obama Administration's Deferred Action for Parents of Americans and Lawful Permanent Residents program ("DAPA"). The Court held that the states had suffered a cognizable injury for purposes of standing because DAPA would have entitled its recipients to obtain driver's licenses under existing state law and providing those licenses would have come at a financial cost to Texas. See id. at 155-56. In denying a stay of the district court's preliminary injunction pending appeal, the Fifth Circuit cited Alfred L. Snapp & Son , explained that Texas possessed a sovereign interest in the maintenance of its own legal code, and held that "Texas's forced choice between incurring costs and changing its laws is an injury because those laws exist for the administration of a state program, not to challenge federal law, and Texas did not enact them merely to create standing." 787 F.3d 733, 749 (5th Cir. 2015). The court reasoned that "if pressure to change state law in some substantial way were not injury, states would have no standing to challenge bona fide harms because they could offset most financial losses by raising taxes or fees." Id. Several months later, the Fifth Circuit affirmed the preliminary injunction on the merits, reiterating and confirming its conclusions as to standing. The Circuit held that "states may have standing based on ... federal interference with the enforcement of state law, at least where the state statute at issue regulates behavior or provides for the administration of a state program and does not simply purport to immunize state citizens from federal law." 809 F.3d 134, 153 (alterations and internal quotation marks omitted). Such "intrusions," the court explained, "are analogous to pressure to change state law." Id.

Like the state plaintiffs in Texas v. United States , the State Plaintiffs here have enacted their reliance on federal census data into law - in some cases, as noted, even into their constitutions. Moreover, as in Texas v. United States , "there is no allegation," let alone proof, that those jurisdictions enacted their laws or ratified their constitutions "to manufacture standing" in these cases. Texas , 809 F.3d at 159. If a citizenship question is added to the decennial census, these Plaintiffs will be subjected to a forced choice: They can use the degraded data, resulting in worse policy; they can spend money to compensate for the damage; or they can change their laws to relieve themselves of the legal obligation to use federal census data in making and enforcing their laws (which would presumably necessitate the expenditure of additional resources to collect data of their own anyway). Such "pressure[ ] to change state law constitutes an injury" within the meaning of Article III. Texas , 787 F.3d at 749 ; see Texas , 809 F.3d at 153.

Accordingly, several Governmental Plaintiffs - including State Plaintiffs New York, Colorado, Connecticut, Delaware, Illinois, Iowa, Maryland, Massachusetts, Minnesota, New Jersey, New Mexico, North Carolina, Oregon, Pennsylvania, Rhode Island, Virginia, and Washington, and Plaintiff New York City - have proved an imminent injury to their sovereign interests through the degradation in quality of federal census data.
