On Feb 18, 2026, America First Legal announced that it had filed an amended complaint in a landmark lawsuit challenging the 2020 Census, in the US District Court for the Middle District of Florida, Tampa Division. The caption matters because it clarifies what this dispute now is and is not.
It is not merely a postmortem about a chaotic pandemic year. It is USFCR, et al. v. Lutnick, et al., it names defendants in their official capacities, including Commerce Secretary Howard W. Lutnick and Acting Census Bureau Director George Cook, and it reiterates that the case belongs before a 3-judge panel. That procedural posture signals a claim about the foundations of political equality, not a quarrel about bureaucratic discretion. The amended complaint also brings the operative mechanism into sharper focus. The 2020 Census, on this telling, was not only miscounted. It was, in key respects, computed.
To see why this is not a minor administrative story, recall what the decennial census is for. The Constitution requires an “actual Enumeration” because representative government requires something basic, namely a determinate answer to how many people live in each place. Congressional seats, Electoral College votes, and a sprawling array of formula grants stand downstream from that answer.
When the census errs, it does not merely inconvenience researchers. It reallocates political power and public money.
In ordinary domains, estimation is often benign. In apportionment, estimation is combustible. The values at stake are not only empirical but civic. A census that becomes an exercise in modeling rather than counting invites the very suspicion that the Enumeration Clause was meant to preempt.
A puzzled reader might ask: “But was the 2020 Census really an algorithmic affair, or was it a pandemic-era operational failure?” The right answer, and the most important update to the public debate, is that it can be both. The amended complaint’s emphasis on massive imputation describes one layer of substitution at the point of enumeration, while the differential privacy regime I described last year describes a second layer of distortion at the point of publication.
Martin Capital is a proud member of the Freedom Chamber. You should be too!
If you want a clean conceptual map, think of the 2020 Census as having two doors through which error and discretion can enter. The first door is how the Bureau decides who gets counted when it cannot obtain an answer. The second door is how the Bureau decides what numbers to publish once answers are in hand. In 2020, both doors were opened wider than Americans were told.
Begin with the official who best symbolizes the second door. The 2020 census was marketed as an “actual enumeration,” a neutral count of people for apportionment and funding. It was not. John M. Abowd, then the Census Bureau’s Chief Scientist, pushed through a new, opaque methodology called differential privacy. The new system deliberately injected mathematical noise into block counts across the country, turning what should have been a headcount into a model with knobs.
The most consequential knob was a single parameter, epsilon, the privacy loss budget. During the critical period, epsilon functioned as a secrecy shroud known only to a small inner circle. Abowd had argued earlier that a straightforward citizenship question posed an intolerable risk to data quality because there was not enough time to test it. He then rushed an algorithmic regime that altered the published count in every neighborhood in America.
That juxtaposition is not merely ironic. It is revealing. If the standard is “do not change the census unless rigorously tested,” then differential privacy fails that standard by design.
The record on the citizenship question fight is not peripheral. It is a window into priorities and plausibility. On Jan 19, 2018, Abowd sent Commerce a technical memo urging rejection of a citizenship question. He later testified in federal court, and the transcript is extensive. The public narrative, reinforced by expert declarations and judicial findings, was that the question would chill participation and degrade data quality.
The administration lost that fight. But the more consequential fight, the one over how the Bureau would publish the data and what kinds of statistical machinery would stand between raw responses and official numbers, continued largely outside public view. Abowd advanced a quiet revolution in disclosure avoidance, adopting differential privacy for the first time ever in a U.S. census. That choice was framed as confidentiality compliance under 13 USC § 9.
The statute matters. So does the Constitution. Confidentiality is a genuine obligation, but it is not a blank check to corrupt the object being protected. The obligation to protect respondent privacy is downstream from the obligation to count accurately for apportionment. Privacy is a constraint on publication, not a license to alter totals.
Differential privacy is often described in soothing language, as if it were a harmless veil draped over a finished portrait. A more accurate metaphor is that it takes the portrait and repaints it with deliberate distortions, then asks the viewer to treat the result as the portrait itself. The algorithm perturbs small-area counts and then postprocesses them so the fabricated numbers look tidy. The output retains familiar columns, but the counts are no longer the counts.
The conceptual mistake is easy to state. If you promise an “actual enumeration,” you are promising that the numbers published for blocks, precincts, and tracts are the result of counting people who exist, not of injecting pseudo-people and erasing real ones to satisfy a disclosure model. There is a categorical difference between suppressing a sensitive cell and falsifying the headcount that defines a political community.
A reader might ask: “Does this really matter if the noise is small?” It matters for two reasons. First, redistricting is a sum of blocks. Distort enough blocks and you distort the district totals that “One Person, One Vote” requires to be nearly equal. Second, the noise is not merely random error that can be assumed to cancel. It is structured error, constrained by postprocessing and by discretionary choices about how the privacy budget is allocated across geographies and categories. Even with a disclosed global epsilon, the distribution of privacy loss across the data product can privilege some small-area accuracy at the expense of others.
That is precisely why transparency about settings and allocation matters.
This brings us to the revised and more complete account of the first door, the one that concerns enumeration itself. The AFL amended complaint spotlights whole-person imputation at a scale that should shock even those who have never heard of epsilon. On this account, the Census Bureau’s own post-enumeration work implies that 10.9 million people, about 3.4 percent of the population, were imputed in 2020, roughly double the level in 2010, when 5.99 million were imputed, and far above 2000, when 5.77 million were imputed.
Even more striking, the filing flags a definitional issue that could push the imputation figure closer to 17.1 million. Whether you treat the higher figure as the right metric or as a warning about classificatory games, the conclusion is the same. In 2020, the Bureau did not merely miss people and later confess it. It filled in a vast number of people by statistical substitution.
The concept is simple. Imagine a school teacher taking attendance. Several students do not answer. The teacher then marks them present or absent by using the answers of nearby students, not because those nearby students know who is present, but because the teacher is committed to turning a partial record into a complete list. If this happens once or twice, you might shrug. If it happens to 3.4 percent of the classroom, you would no longer call the result attendance. You would call it a model. Now scale the model to the political community, and you get the core normative problem. Representation is not supposed to be a function of how aggressively an agency is willing to fill in blanks.
At this point the reader might object: “Imputation is not new. Courts have dealt with it.” That is true, and it is precisely why scale and context matter. A limited imputation technique, used to resolve discrete missing data problems, can be defended as a form of record completion rather than sampling. But the more the Bureau substitutes imputed persons for enumerated persons, the less plausible it becomes to treat the output as an “actual enumeration” in any robust sense.
Moreover, in 2020 the imputation layer did not occur in a vacuum. It occurred alongside unprecedented operational disruption and alongside a publication regime that deliberately obscured the boundary between what was counted and what was computationally manufactured. When a large imputation system meets a secrecy-based publication system, the combined effect is not merely error. It is unaccountability. The public cannot tell where the census is wrong, and local governments cannot reliably use ordinary correction pathways to fix it, because the published product is, by design, no longer a transparent record of what was found.
This is where Florida becomes the clearest case study. The original debate often treated Florida’s grievance as rhetorical, a large state complaining, as large states do. The updated filing makes it numerical. Florida’s undercount is framed at 3.48 percent, roughly 760,000 people, roughly the population of an entire Congressional district or Electoral Vote. That is not a rounding error. It is an event with constitutional consequences.
More pointedly, the filing alleges that Florida narrowly missed an additional House seat by about 172,000 people. That number matters because it converts a vague complaint into a counterfactual apportionment fact. If you missed a seat by 172,000 people and you undercounted by about 760,000, then the miscount is not a lament. It is the margin.
The undercount story does not end with Florida. The Bureau’s Post-Enumeration Survey in 2022 identified statistically significant coverage errors in 14 states, with a pattern of overcounts and undercounts that, on my view, cannot be dismissed as politically irrelevant. Florida and Texas were among the most prominent undercounted states, while other states kept or gained seats they would not have kept or gained under a more accurate count. Analysts have estimated that the net effect was a shift of around 9 House seats away from Republican-leaning states and toward Democrat-leaning states, with the Electoral College moving with them.
Those seats also carry money. The original estimate I cited was more than $86 billion in federal formula funds following the distorted apportionment and related data products. These are not mere administrative dollars. They are distributional levers in education, health care, transportation, and countless state and local budgets, improperly redistributed to Democrat states.
The amended complaint adds an even larger national allegation that must be handled carefully in public argument. It points to the Bureau’s post-enumeration work as showing 18.8 million people missing nationally and emphasizes that the key PES results came out in spring 2022, after apportionment data and redistricting products were already released in 2021.
This temporal point is critical. Even if one were to grant the most generous pandemic excuses, the official machinery locked in representation and funding before the error could be fully appreciated, and without a robust means of correction afterward.
A confused reader might ask: “If the Bureau later acknowledged error, why not just fix it?” In an ordinary data system, that is exactly what would happen. But the census is not an ordinary data system. It is tied to statutory timelines, constitutional functions, and political processes that harden quickly. Once apportionment is delivered and redistricting data are deployed, legislatures draw maps, candidates run, voters vote, and the decade begins. This is why remedies must be structural, not merely rhetorical. It is also why the AFL lawsuit, and the way it is framed, matters. It is an attempt to move the issue from commentary into institutional action.
This brings us back to differential privacy and to the problem of auditability. Even if the dominant source of net undercount is operational, the public still needs to know which parts of the published product reflect enumeration and which reflect synthetic adjustment. Differential privacy makes that boundary difficult to see because it deliberately injects falsity into small-area totals and because its settings, in the most consequential period, were treated as secret.
The core lever is epsilon. Abowd kept this number secret through 2020. Researchers, states, and map drawers who saw early demonstration files warned that the counts were veering away from reality. They had no reliable method to determine whether anomalies were genuine miscounts or the algorithm’s artifacts. Worse, the secrecy and the design of the publication process crippled the ability of local governments to find and fix mistakes. Traditionally, if a city discovers a counting error affecting funding, it can appeal through the Count Question Resolution program. But when published numbers are intentionally altered, the safeguard collapses because the data are wrong on purpose.
No one can separate genuine miscounts from the algorithm’s pseudo-miscounts. Alabama’s attempt to challenge this secrecy in State of Alabama v. US Department of Commerce was dismissed for lack of standing, and the practical message was blunt. Even a state that plausibly loses billions cannot easily obtain judicial review of a method that makes the census less transparent.
The Bureau later revealed a global epsilon of 19.61. But disclosure after the decisive moment is not transparency. It is history. Moreover, the controversy was never only about a single global number. It was about the inability of outsiders, including Congress, to audit how the dial governed the size and distribution of noise across the nation. “Trust me” is not an acceptable epistemic posture for a decennial process that controls representation.
Now return to the core constitutional point. The Supreme Court has made clear that statistical sampling for apportionment is illegal on statutory grounds. The Court has also, in other contexts, emphasized that the census should aim at accuracy, even while granting the political branches leeway in choosing methodologies. Those two ideas can be reconciled only if methodology serves enumeration rather than replacing it.
The danger of 2020 is that methodology began to replace enumeration. At the first door, the Bureau relied on whole-person imputation at a scale that looks like estimation of the population rather than counting of the population. At the second door, the Bureau adopted differential privacy in a form that injected synthetic alterations into the very small-area totals that law and politics require to be stable. Each door alone is concerning. Together they create a system in which the public is told it has been counted, while the agency reserves discretion to fill in missing people and to perturb the published numbers, with limited external capacity to distinguish counting from computation.
If you wonder what this means in practical terms, consider how redistricting is actually done. A map drawer does not begin with a philosophical treatise about representation. He begins with a spreadsheet of blocks. He aggregates blocks into precincts, precincts into districts, and districts into a statewide plan. If block totals are distorted, the whole plan inherits the distortion. If the distortions are distributed unevenly, the plan inherits a systematic bias. The harm is not only to the abstract ideal of equality. It is to the ordinary citizen whose neighborhood is moved, on paper, into a different political reality.
This is why the AFL requested remedy is so important, and why it harmonizes with the remedy I called for last year. The amended complaint seeks corrected or supplemental apportionment data, along with a corrected or supplemental P L 94-171 redistricting dataset, excluding population derived primarily from statistical methods, and redistributing it to states.
That is, in essence, a legal demand for what I called a 2020 Census Reproduction Project, republishing truthful totals using traditional disclosure avoidance rather than a regime that changes small-area population counts. The difference is institutional. What I framed as congressional oversight and statutory reform, AFL now frames as judicially compelled corrective action.
A reader might ask: “How is the case still alive, years later?” The procedural update answers that question. The amended filing is designed to survive dismissal by clarifying the legal vehicle. The prior panel, on this account, dismissed the case as untimely under a 4-year statute, while the amended complaint frames the suit under the Administrative Procedure Act against the United States, arguing a 6-year limitations period. Put aside the technicalities and notice the deeper point. The plaintiffs are not merely rearguing the politics. They are attempting to keep open the channel by which a court can order correction rather than resignation.
There is also, in Florida, a concrete reason this is not merely academic. Florida is acting mid-decade. A special legislative session on congressional redistricting is slated for April 2026. Mid-decade redistricting is itself a sign that census-driven maps are not a stable background fact but a live arena of struggle. If a state is revisiting its districts now, then a debate about whether it was shorted a seat, and whether the underlying data were produced lawfully, is not retrospective. It is contemporaneous.
What, then, should be done? Congress must act, and courts should not shrink from enforcing the constitutional and statutory limits that already exist. The remedy remains simple in outline, even if contested in politics. The Bureau should be directed to reproduce the 2020 products using raw data, published in a form that preserves truthful population totals for the geographies that govern apportionment and redistricting. Confidentiality can be protected through targeted suppression and “undetermined” flags where needed, rather than by falsifying totals.
Differential privacy, if used at all, should be confined to research products explicitly labeled as unofficial and barred from use in apportionment and redistricting. The citizenship data program, built from administrative records, should be resumed and expanded so that policymakers are not forced to deliberate in the dark about the citizen population and the scale of noncitizen inclusion in representation and funding. Counting persons need not mean blinding the polity to relevant distinctions, and it certainly does not mean adopting methodological opacity as a governing principle.
There will be those who say that the census has always involved judgment and therefore the 2020 controversies are overblown. Judgment, yes. Fabrication, no. In the early republic, census records were publicly inspectable lists. Confidentiality arrived later, and even then it did not require falsifying totals.
The modern notion that confidentiality compels the deliberate corruption of block-level headcounts is not a constitutional mandate. It is a bureaucratic choice. If the Bureau insists its hands are tied by privacy statutes, Congress can untie them by clarifying that accuracy for apportionment comes first, and that privacy must be protected by suppression, aggregation, and undetermined flags, not by injecting synthetic population changes.
The deeper point is philosophical but not abstract. Political equality is a matter of counting. Counting is a matter of truth. Once truth is treated as negotiable, whether through mass imputation at the enumeration stage or through secret noise at the publication stage, the census ceases to be the baseline of democratic legitimacy and becomes another instrument of technocratic power, skewed to the benefit of exactly one party. That is why the 2020 census should not be remembered as an “experiment.” It should be treated as a cautionary case of how a foundational constitutional practice can be altered under the guise of technical necessity.
If you believe, as I do, that the 2020 process was engineered by a partisan actor, then the Abowd story remains central. He fought President Trump’s effort to include a citizenship question, then implemented a differential privacy system that, as a practical matter, helped prevent later recovery of precise local truths about who lives where, including how many noncitizens were counted.
But the amended complaint now adds what the public debate too often missed. The rigging, on this account, was not only in the release algorithm. It was also in the decision to fill in millions of missing people through imputation at historically high levels. When those two choices are combined, they yield a census that is neither an “actual enumeration” nor a transparent record. It is a constructed artifact. That is not what the Constitution promised.
Restore the count, restore the House, and restore public trust in the census as the nation’s most basic act of self-measurement.

Mr. Muse’s article on the census count was spot on and eye opening. You can just see the Wizard of Oz pulling the levers to get what he (they) want regardless of reality!
Excellent paper and another frustrating example of another scam foisted upon our country by wicked weasels. Weasels that never seem to be held to account for their misdeeds, or not adequately. It reminds me of a wonderkind convincing his less technically adept boss to adopt his technical strategy by regaling him/her with technical jargon, concepts, and lots of wonky acronyms. The boss nods like they understand and grasp the ask and ultimately approve the ask, not fully understanding what they've signed on to.
NEVER TRUST anyone hitting using technical terms, concepts, jargon, and acronyms, etcetera to get you to do something.
They are (multiple choice):
1.) Poor at communications.
2.) Arrogant.
3.) Playing on your ego.
4.) Don't know what their talking about.
5.) Disingenuous, dishonest, a grifter.
6.) Working on commission (kidding?).
7.) All the above.
So, that's how you corrupt and $cam our country. Overwhelm us with misaapplied and fraudulent science or pseudo-science. By the time enough smart people really dig into and get the data and untangle the web, the statute of limitations runs out. What a scam that is... it happens again and again.
