The composite family. Each room is a statistical composite, assembled from separate distributions with separate sources. The family at the median income did not also have the median house, the median car, and the median diet. No single family described here ever existed; each fact tells you, in its provenance drawer, which real population it was measured from.

Characteristics of New Single-Family Houses Completed (Census C-25 / Series H-150)
U.S. Census Bureau, 2024 · source
Confidence: A — Official series
Curator note: From the Census Bureau's Survey of Construction (C-25 annual report, Series H-150). 1973 is the first year of data. New-construction median was 1,525 sq ft — this is NOT the median of all existing homes (which would be smaller, as older stock persists). By 1980: 1,595 sq ft. The 2020s room shows 1,500 sq ft for the existing stock (AHS 2023) — new homes grew 60% from 1973 to 2024, but the existing stock median is lower because older, smaller homes remain.
Source note: Annual data on median square feet of floor area in new single-family houses completed, from the Census Bureau's Survey of Construction (SOC). Data available 1973-present. The C-25 annual reports (c25ann2003.pdf through c25ann2017.pdf) and H-150 reports (h150-73A.pdf through h150-89.pdf) are archived in vitrine-research/20-census-construction/. They contain the historical table 'Median and Average Square Feet of Floor Area in New Single-Family Houses Completed.' Pre-1999 reports use Series H-150 designation. Note: this measures NEW construction only, not the existing housing stock — the AHS measures the entire stock and yields lower medians because older, smaller homes remain in the inventory.

Source note: Per-commodity sheets of the fresh-fruit and fresh-vegetable workbooks, farm-weight 'Per capita availability' column. Availability is a disappearance estimate: production plus imports, less exports, non-food use and (for fruit) shipments to US territories, divided by population. It measures what the food supply made available per person, not intake — ERS publishes a separate loss-adjusted series for consumption-like figures and this is not it. Each sheet also prints a retail-weight column derived by a stated conversion factor (0.92 broccoli and peppers, 0.94 avocados, 0.91 grapes); the unadjusted farm-weight column is taken and the factor is disclosed rather than applied. The two workbooks do not share a layout — the fruit sheets carry an extra 'Shipments to U.S. Territories' column and print the 'Farm' sub-header a row lower — so the extraction locates every column by its printed label and then verifies the result arithmetically: farm per-capita must equal food availability divided by population, for every year.

Time Spent in Home Production in the Twentieth-Century United States: New Estimates from Old Data
Cambridge University Press (Journal of Economic History), 2009 · source
Confidence: C — Reconstructed from period surveys
Curator note: Ramey (2009) Table 7, 'All Prime-Age Men' column. Early estimates from Purnell Act studies and Lundberg et al. (1934); 1965+ from AHTUS/BLS. Men's hours rose 13 hrs/week across the century (3.9→16.8), partially offsetting women's decline. Numbers in italics in source = partially extrapolated.
Source note: Valerie A. Ramey, JEconHist 69(1), March 2009, pp. 1–47. Reconstruction from historical time-diary studies (Purnell Act studies 1920s, Wilson 1929, USDA 1944) linked to AHTUS/BLS modern surveys. Draft version: NBER Working Paper w13985 (May 2008, 63pp) — data tables are numerically identical to the published version; differences are prose tightening and table reformatting (5→5A/5B, etc.). Tier C (period-survey reconstruction). Key tables: Table 5A (nonemployed women), Table 6A (all women, prime-age), Table 7 (men, prime-age), Table 8A (all ages), Table 3 (component breakdown). Note: Ramey does not use the 1992-94 survey (missing data), so no 1990s benchmark. Splice point to ATUS: Ramey measures women-specific home production ages 18-64; ATUS measures all-adult household activities age 15+ — a concept splice that must caveat (Plan 004 Measure guard).

Table FI-200: Motor Vehicle Traffic Fatalities, 1900-2023 (Highway Statistics 2023)

Confidence: A — Official series
Curator note: Absolute deaths peaked in this decade, at 55,600 in 1972 — the highest figure in the table's 124 years.
Source note: The whole 1900-2023 span in one FHWA table, so the fatality-rate series needs no splice between estimate and registration eras. Four rate columns are published side by side (per 1,000 miles of road, per 100 million annual VMT, per 100,000 registered motor vehicles, per 100,000 licensed drivers); the museum takes the per-100-million-VMT column, and the extraction script recomputes it from the table's own fatality and VMT columns for every year rather than trusting its position. FHWA footnote (3) records a definitional change: beginning in 1976 the count includes only people who died within 30 days of the crash, so the earlier years are counted on a wider window and the two halves are not the same measurement. The 1900-1995 rows were cross-checked against FHWA's separately-published Highway Statistics Summary to 1995 (April 1997): 95 of 96 years reproduce exactly, the exception being 1995, that publication's terminal provisional year, since revised from 41,770 deaths to 41,817 (see docs/verification-log.md).

Curator note: The fall from the 1960 peak is already a quarter of the way down, and it happens before the shift in who was giving birth: the married share of these mothers falls across the following decades while the rate itself keeps dropping.
Source note: The All-races block, 15-19 'Total' column. The table repeats its whole structure once per race and origin group and prints 15-17 and 18-19 sub-columns beside the total, so both the block and the column are located explicitly by the extraction script rather than by position. Selected years, not annual: NCHS publishes 1950, 1960, 1970, 1980, 1990, 1995, 2000, 2005, 2010 and then most recent years, and the gaps between printed rows are not interpolated. This 2019 edition is cited rather than the newer 2020-2021 one because the later edition drops 2010 from its selected years. Cross-checked against that later edition (12 overlapping years, all identical) and against NVSR 72-1 Table 2, compiled independently of the trend tables (6 overlapping years, all identical). Note that cdc.gov returns 403 to browser-like User-Agents and serves plain tool agents instead — the opposite of bls.gov; scripts/link_check.py retries 403s with a plain agent for this reason.

Source note: Started 1978, triennial/quadrennial. Tracks appliance ownership (refrigerator, washing machine, air conditioning) and housing characteristics. AC diffusion: 1993 RECS 68%, 2009 RECS 87%, 2015 RECS 87%. Useful for diffusion and home panels as complement to AHS.

Curator note: From BTS Figure 2-7 (Census Bureau decennial census, 1970). 17.5% had no vehicle, 47.7% had one, 29.3% had two, 5.5% had three or more. The CEX 1972-73 (Bulletin 1992, Table 1) reports a complementary figure: 80.1% of families had at least one automobile (avg 1.3 per family) — the difference reflects source (Census housing units vs CEX families) and timing (1970 vs 1972-73). This fact uses the BTS/Census figure for series consistency with other decades. By 1980: 87.1%. Population: all occupied housing units.

Reading the atlas
Provenance is in the scan-line: every exhibit's row names its value, confidence tier, the population actually measured, and the source record. Chart points and stage glyphs open the same record.
Rising series draw in petrol, falling in ember. An omitted illustration means no exhibit was selected, not that the object was historically absent.
