# Census Data Products Tree [[How the Census Is Actually Counted]] ends at a state total ready for tabulation. [[How the Census Apportions Congress]] picks that total up and turns it into seats. This map covers the branch between and beside them — **everything the count actually produces**, arranged not by subject or by audience but by the only variable that turns out to decide their fate: whether a statute says when they must appear. The organizing fact is a two-line asymmetry. **13 U.S.C. § 141 creates exactly two delivery obligations, and both of them move political power**: the apportionment tabulation owed to the President within nine months of Census Day under § 141(b), and the P.L. 94-171 redistricting tabulations owed to the states within one year under § 141(c). Every other census product — the Demographic and Housing Characteristics file, the detailed race and ancestry tables, the [[American Community Survey]] that carries the decade between censuses, the annual population estimates that drive federal formula funding — has **no statutory deadline of any kind.** They exist because the Bureau publishes them. What the 2020 cycle and the 2026 calendar together show is that the asymmetry cuts in both directions, and neither one the way the statute reads. **Both deadlined products were delivered months late and nothing happened**, because § 141 attaches no remedy to its own dates. And the undeadlined products are being reshaped right now by a Commerce order that required no statute, no rulemaking and no vote: [[Disclosure Avoidance for Statistical Products]] (DAO 216-26), effective June 4, 2026, bars the disclosure-protection method the Bureau built its modern products on, and the 2025 ACS 1-year estimates have been indefinitely postponed since August 2026 as a direct result. The statute governs a schedule it cannot enforce and says nothing about the content it cannot protect. Part of the census cluster routed from [[Census]]. Time-slice: products, schedules and release status as of **September 23, 2026**. > [!note] How to read this chart > `■` = the frame · `◆` = a product tier · `★` = a hard statutory deadline attached to the product · `⚠` = published at the Bureau's discretion, with no deadline in law · `✕` = withheld, halted or barred · `[live]` = in motion as of the build date · `·` separates peer items on one line. Bracketed dates in Tier 1 and Tier 2 are the **2020-cycle actuals**, which are the only complete record of what the pipeline does under pressure. Everything inside the fence is plain text; wikilinks live in the prose, Notes and See also. No officeholders are named inside the fence — the seats appear in the dated table below it. ``` CENSUS DATA PRODUCTS TREE — WHAT COMES OUT, AND WHICH PARTS ARE OWED │ Legend: ■ frame ◆ tier ★ statutory deadline ⚠ no deadline in law ✕ withheld/barred │ [ ] = 2020-cycle actual release · [live] = in motion as of the build date │ Time-slice: products and release status as of Sept 23, 2026 │ ■ 0. THE FRAME — TWO PRODUCTS ARE OWED. EVERYTHING ELSE IS OFFERED. │ 13 U.S.C. § 141 creates two delivery obligations and no others. Both of them │ allocate political power. Nothing that a school district, a hospital, a court or a │ business uses is owed to anyone on any date. │ ├─ ★ § 141(b) .... apportionment tabulation → the President ....... 9 months │ ├─ ★ § 141(c) .... P.L. 94-171 tabulations → the 50 States ........ 1 year │ └─ ⚠ every tier below ............................................. no deadline │ │ ◇ AND THE DEADLINES HAVE NO REMEDY. § 141 sets dates and provides nothing that │ happens if they are missed — no penalty, no cause of action, no default rule. │ In the 2020 cycle both were missed by roughly four months. See Tier 1. │ ├─◆ 1. THE DEADLINED TIER — THE TWO PRODUCTS THAT ALLOCATE POWER │ │ │ ├─ ★ APPORTIONMENT COUNTS — 13 U.S.C. § 141(b) │ │ Content: one number per state, plus the resident population of the U.S. │ │ Recipient: the President, who transmits to Congress. Not a public dataset; │ │ a statement of totals. Everything about it is fixed except the date it lands. │ │ Due: within 9 months of the decennial census date (Apr 1) → Dec 31 of census year │ │ 2020 cycle: due Dec 31, 2020 ......................... [Apr 26, 2021 — 116 days late] │ │ └─ Consumer: the method of equal proportions, then 435 seats, then the │ │ Electoral College allocation that follows from them automatically. │ │ │ └─ ★ P.L. 94-171 REDISTRICTING FILE — 13 U.S.C. § 141(c) │ Content: population and voting-age population by race and Hispanic origin, │ down to the census block, on the geography each state asked for in advance. │ Recipient: each state's designated officer or public body — the governor and │ the legislative leaders of both houses, by name, in every state. │ Due: "as expeditiously as possible," and in any event within 1 year of Census Day │ 2020 cycle: due Apr 1, 2021 ................ [Aug 12, 2021 FTP · Sep 16, 2021 web] │ ├─ Consumer: every congressional and legislative map in the country, plus │ │ every Voting Rights Act analysis run against one. │ └─ ⚠ THE DOWNSTREAM EFFECT OF A LATE DELIVERY IS NOT SYMMETRIC — state │ constitutional redistricting deadlines do not move when the federal │ delivery slips. The time comes out of the public-comment end, not the │ mapmaking end. A late file shortens scrutiny, not drafting. │ ├─◆ 2. THE UNDEADLINED DECENNIAL TIER — WHAT THE PUBLIC ACTUALLY READS │ │ Same enumeration, same statute, no date attached to any of it. The 2020-cycle │ │ actuals below are the record of how long "no deadline" turns out to mean. │ │ │ ├─ DEMOGRAPHIC PROFILE ................................... [May 25, 2023] │ │ The single-page summary product most journalism and most local government uses. │ ├─ DEMOGRAPHIC AND HOUSING CHARACTERISTICS FILE (DHC) .... [May 25, 2023] │ │ The workhorse: age, sex, race, ethnicity, household relationship, tenure. │ │ ⚠ 3 years and 2 months after Census Day. Nothing in law was breached. │ ├─ CONGRESSIONAL DISTRICT SUMMARY FILES .................. [Aug 31, 2023] │ │ The same data re-cut onto the districts the redistricting file produced. │ ├─ DETAILED DHC-A — detailed race and ethnicity groups ... [Sep 21, 2023] │ ├─ DETAILED DHC-B — households by detailed group ......... [Aug 1, 2024] │ ├─ PRIVACY-PROTECTED MICRODATA FILE (PPMF) ............... [Aug 5, 2024] │ ├─ SUPPLEMENTAL DHC (S-DHC) ............................. [Sep 19, 2024] │ │ Last product of the cycle — 4 years and 5 months after Census Day. │ └─ ◇ THE STRUCTURAL POINT: the two deadlined products landed within 5 months of │ each other. The undeadlined tier took the next three and a half years, in an │ order the Bureau chose, at a level of detail the Bureau chose, and a tier │ published by choice can be reduced or dropped by choice. See Tier 5. │ ├─◆ 3. THE CONTINUOUS TIER — WHAT CARRIES THE DECADE │ │ The decennial answers a handful of questions once every ten years. Everything │ │ else people think of as "census data" is this tier. Authority: 13 U.S.C. §§ 141 │ │ and 193; response mandatory under § 221. Deadline: none, anywhere. │ │ │ ├─ AMERICAN COMMUNITY SURVEY — 1-YEAR ESTIMATES │ │ Areas of 65,000+ population. Income, poverty, insurance, education, commuting, │ │ language, disability, internet access, housing cost burden. │ │ Normal cadence: September of the following year. │ │ ✕ [live] 2025 ACS 1-YEAR: INDEFINITELY POSTPONED since early August 2026. │ │ Not cancelled, not scheduled. Cause is the control layer at Tier 6. │ ├─ ACS 1-YEAR SUPPLEMENTAL ESTIMATES — areas of 20,000+, selected tables │ ├─ ACS 5-YEAR ESTIMATES — every geography down to the block group │ │ The only source of small-area socioeconomic data in the United States. │ │ 2020-2024 vintage released Jan 29, 2026. │ ├─ ACS PUBLIC USE MICRODATA SAMPLE (PUMS) — individual records, coarsened, │ │ released at the PUMA level (~100,000 people). 5-year PUMS: Mar 2026. │ └─ ◇ WHY THIS TIER IS THE EXPOSED ONE: it is annual, so an interruption is not a │ delayed product but a MISSING YEAR, and a missing year in a 5-year estimate │ degrades the small-area data for five subsequent releases. │ ├─◆ 4. THE CARRY-FORWARD TIER — THE NUMBERS BETWEEN THE COUNTS │ │ POPULATION ESTIMATES PROGRAM (PEP). Annual vintages, released on a flow basis: │ │ national and state, then counties, then cities, towns and housing units. │ │ Vintage 2025 city/town and housing-unit estimates released June 25, 2026. │ ├─ Method: the decennial count is the BASE. Each vintage carries it forward with │ │ births, deaths and migration. There is no re-count and no correction pass. │ ├─ Consumers: federal formula funding · ACS and CPS survey controls · the denominator │ │ under most published federal rates (crime, mortality, unemployment by area). │ └─ ★★ THE COMPOUNDING FACT — THIS IS WHY AN UNDERCOUNT COSTS A DECADE. │ A housing unit missing from the 2030 address list is missing from the 2030 │ base, and every vintage through 2039 is computed FROM that base. The error │ is not corrected annually; it is carried, and it is carried into the formulas. │ A city with no House seat to lose still loses money every year until 2040. │ ├─◆ 5. THE CUSTOM AND RESTRICTED TIER — NOT PUBLISHED, REQUESTED │ ├─ SPECIAL TABULATIONS — a cut the Bureau does not publish, made on request, │ │ at cost, subject to disclosure review. Discretionary end to end. │ ├─ RESTRICTED MICRODATA via the Federal Statistical Research Data Centers — │ │ approved project, secure facility, sworn status, 13 U.S.C. § 214 exposure. │ ├─ THE 72-YEAR RULE — an individual's own census record goes to the National │ │ Archives and becomes fully public 72 years on. 1950 opened 2022; 1960 due 2032. │ └─ ◆ MAPPED SEPARATELY — the full access ladder, its costs and its penalties are a │ crosswalk of their own and are named here only so the tree is complete. │ └─◆ 6. THE CONTROL LAYER — WHAT DECIDES WHETHER A TIER CAN BE PUBLISHED AT ALL │ Every product above passes a disclosure-avoidance step before release. The method │ is not set by statute. Title 13 § 9 states the CONFIDENTIALITY OBLIGATION and │ leaves the TECHNIQUE entirely to the department. That gap is the control point. │ ├─ ✕ DAO 216-26, "Disclosure Avoidance for Statistical Products" — Department of │ Commerce administrative order, effective June 4, 2026. Applies to the Census │ Bureau and the Bureau of Economic Analysis. │ ├─ § 5.01(c): "Any use of noise infusion is inconsistent with the │ │ Department's policies." That bars the entire family of methods the │ │ 2020 products were protected with, including the TopDown Algorithm. │ └─ § 5.02: coarsening (rounding, ranges, aggregation) is the PREFERRED │ category; suppression is permitted only as a LAST RESORT. ├─ ◇ WHAT AN INSTRUMENT LIKE THIS IS: not a statute, not a rule, not a Federal │ Register notice with a comment period. An internal departmental order, signed │ and effective, reaching two statistical agencies and every product they publish. └─ [live] EFFECTS ALREADY ON THE RECORD, per the Bureau's own August 2026 statement: ├─ 2020 Census data already published ............. unaffected ├─ 2030 Census .................. demonstration product planned mid-2027 ├─ ACS ............... gradual transition, full compliance by 2029 ├─ Quarterly Financial Report ......... switching to suppression ├─ County Business Patterns ........... "exploring alternatives" └─ LEHD ........ continues noise infusion until data-sharing agreements update ``` ## The seats, as of this writing No officeholders appear inside the fence. These were web-verified on **2026-09-23** for the prose and Notes only. | Seat | Holder | Status | |---|---|---| | Secretary of Commerce | Howard Lutnick | Confirmed February 18, 2025; DAO 216-26 is a Secretary-level order | | Director, Census Bureau | *vacant* | No Senate-confirmed Director since 2025 | | Performing the duties of the Director | George M. Cook | Since September 19, 2025; a Commerce Deputy Under Secretary. Author of the Bureau's August 17, 2026 statement on the new policy | ## Notes - **The deadlines have no remedy, and that is the finding.** § 141(b) and § 141(c) set dates. Neither subsection attaches a penalty, a cause of action, or a default consequence to missing one. In the 2020 cycle the apportionment tabulation was due December 31, 2020 and delivered **April 26, 2021**; the P.L. 94-171 file was due April 1, 2021 and delivered **August 12, 2021**. The pandemic is the explanation, but the absence of any consequence is structural and survives the explanation. This is the same shape the [[Federal Statistical System Tree]] build found in a different part of the system: a fixed date with no enforcement clause is a schedule, not a shield. - **The 2025 ACS 1-year estimates have not been released, and no date exists.** The Census Bureau announced in early August 2026 that the release was being reassessed for compliance with the new order, and its own advisory states plainly: "The release date for the 2025 ACS 1-year estimates is being determined." More than 100 organizations wrote to the Department on **September 4, 2026** asking that the delay be ended. As of September 24, 2026, twenty days later, it has not been. Note a minor discrepancy in the record: the signatory letter dates the postponement announcement to August 4, 2026 and the Bureau's own ACS updates page carries it as August 6, 2026. - **What DAO 216-26 actually bars.** Noise infusion is the family of methods that protects a published table by perturbing the numbers in it rather than by hiding or coarsening them. [[Differential Privacy]] as implemented in the 2020 TopDown Algorithm is a noise-infusion method. The order does not name differential privacy or swapping; it names the category, which is broader. The permitted replacements — coarsening first, suppression as a last resort — are the two techniques that reduce what a table says rather than how precisely it says it. The trade is therefore not privacy for accuracy but **detail for perturbation**, and it lands hardest on exactly the small-geography, small-group tables that the detailed products exist to provide. - **The 2030 disclosure-avoidance system is an open question this map does not answer.** The Bureau has said a demonstration product is planned for mid-2027. What method the 2030 decennial products will use, and whether the P.L. 94-171 file itself changes shape as a result, is not on the public record as of this writing and is left `[unconfirmed]` rather than guessed. It is the single most consequential unresolved item in the tree, because Tier 1 is the one tier that cannot simply be delayed. - **County Business Patterns and the Quarterly Financial Report are in the tree's shadow.** Both are named in the Bureau's August 2026 statement, and neither is a census-of-population product. They are included in the control layer because they demonstrate the order's reach: one departmental instrument, two agencies, products spanning demography and economics. - **Two things deliberately not asserted.** No dollar figure is attached to the formula-funding consequence in Tier 4 — the widely cited per-person-per-year estimates come from advocacy analyses with differing methodologies and denominators, and none is carried here. And no claim is made that the undeadlined tier is *being* cancelled; what is on the record is that it is being changed by an instrument that needed no legislative step, which is a different and more precise statement. - **Why the tiering is the map.** A subject-matter arrangement of census products — people, housing, economy — is the arrangement the Bureau itself publishes and it conceals the thing that matters. Sorted by legal obligation instead, the products fall into a tier that must appear and cannot be made to appear on time, and a tier that need never appear and is the only one anybody outside a redistricting room reads. ## See also - [[Census]] · [[How the Census Is Actually Counted]] · [[How the Census Apportions Congress]] · [[Census Bureau Org Chart]] - [[Census Data Access Crosswalk]] — who may read each of these products, on what terms, and at what price - [[American Community Survey]] · [[Differential Privacy]] · [[Public Law 94-171]] · [[Disclosure Avoidance for Statistical Products]] - [[Census Bureau]] · [[Department of Commerce]] · [[Bureau of Economic Analysis]] · [[Federal Statistical System Tree]] · [[Statistical Policy Directive No. 1]] - [[Census Undercount]] · [[2020 Census]] · [[2030 Census]] · [[Gerrymandering]] · [[Redistricting Timeline 2025-2026]] · [[One Person One Vote]] - [[Foundations Hub]]
