Homeownership Rate by State: 1900 to 2000
U.S. Census Bureau, 2000 · source
Confidence: A — Official series
Curator note: From Census Bureau decennial time series (owner.pdf). Up from 45.6% in 1920 — the 1920s boom had raised the rate. The Depression would drive it down to 43.6% by 1940 (foreclosures, ~1,000/day at peak). The Home Owners' Loan Corporation (HOLC, 1933) and FHA (1934) were created to stabilize the housing market.
Source note: Time series of homeownership rates from 1900 to 2000 by state and nationally. 1950 national rate: 55.0%. 1940: 43.6%. 1960: 61.9%. Also see companion table: https://www2.census.gov/programs-surveys/decennial/tables/time-series/census-housing-tables/ownerchar.pdf

Confidence: A — Official series
Curator note: BLS series CUUR0000SEHA. Rent fell from 31.2 in 1930 to 21.4 in 1934-35, back to its 1913 level, and had recovered only to 23.7 by 1939. Shelter, the price that refused to fall in the 1920s, finally did — by 31%. Landlords cut rather than hold empty units, and the sticky line in the budget turned out to be sticky in both directions, just slower downward.

Curator note: From CDC MMWR Surveillance Summary Vol. 43 No. SS-3, Table 1. Consumption doubled from 665 in 1920 despite the Depression. By 1939 it reached 1,900. Total U.S. consumption was 119.3 billion cigarettes in 1930.

Apparent Per Capita Alcohol Consumption: National, State, and Regional Trends, 1977-2023 (Surveillance Report #122)
National Institute on Alcohol Abuse and Alcoholism, Division of Epidemiology and Prevention Research (Alcohol Epidemiologic Data System), 2025 · source
Confidence: A — Official series
Curator note: Repeal took effect in December 1933, and 1934 is the first year the table can report again. The decade opens inside Prohibition, so 1934 rather than 1930 is its first published figure. Consumption resumed at well under half the 1911-1915 level and took until the 1940s to approach the pre-Prohibition range.
Source note: Table 1, 'Apparent per capita ethanol consumption, United States, 1850-2023', all-beverages column. Apparent consumption is derived from legal beverage sales and shipment data collected from States, the National Alcohol Beverage Control Association and industry sources, divided by Census population: it measures what the state could count, not what was drunk, which is why national Prohibition appears in the table as the literal word '(Prohibition)' and no numbers for 1920-1933. The report's own note records that data prior to 1977 are from Hyman et al. 1980, so the early half of this official series is republished scholarly work. Pre-1934 figures are published as multi-year ranges, not single years. The archived copy in samples/ was confirmed sha256-identical to the document served at this URL on 2026-09-01 (see docs/verification-log.md).

BLS Public Data API v2
U.S. Bureau of Labor Statistics, 2024 · source
Confidence: A — Official series
Curator note: BLS series CUUR0000SAF1. Food fell from 16.5 in 1929 to a trough of 10.4 in 1933 — a 37% collapse that returned the price of eating to its 1913 level, twenty years erased — and recovered only to 11.8 by 1939. Cheaper food did not mean a better-fed family: incomes fell faster and unemployment reached roughly a quarter of the labour force, which is precisely why this room still declares an income gap. Deflation is not affordability.

Historical Statistics: Average Hourly Earnings of Manufacturing Production Workers (Series D 766, D 765-767, D 802-804)
U.S. Census Bureau, 1975 · source
Confidence: A — Official series
Basis: Hourly rate
Curator note: From Historical Statistics Vol 1, Series D 802-804. The anchor year is 1930 ($0.55/hr, 55 cents exact). The Depression crushed wages: hourly earnings fell 20% from 1930 to 1933 ($0.44/hr), and weekly hours fell from 42.1 to 38.1 (part-time work, layoffs). Recovery: by 1935: $0.54/hr, 36.6 hrs/wk, $19.91/wk. The NIRA (1933) established minimum wages and maximum hours.
Source note: Series D 766 (hourly earnings 1890-1914), D 765-767 (manufacturing production workers 1909-1929), D 802-804 (all manufacturing 1919-1948). Pre-FRED CES wage data. Used as the wage anchor for 1900s-1930s rooms (Plan 013). The population skews urban, industrial, male — see the manufacturing-wage-proxy assumption.

Table FI-200: Motor Vehicle Traffic Fatalities, 1900-2023 (Highway Statistics 2023)
Federal Highway Administration, Office of Highway Policy Information, 2025 · source
Confidence: A — Official series
Curator note: Thirty-one thousand deaths, with no federal crash standards for cars, no seat belts and no national safety agency.
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: Ramey (2009) Table 6A, 'All Prime-Age Women' column. Reconstruction from historical time-diary studies (Purnell Act 1920s, Wilson 1929, USDA 1944) linked to AHTUS/BLS surveys from 1965. Includes food prep, house cleaning, clothing care, childcare, purchasing, and household management. Numbers in italics in source = partially extrapolated. Draft version (NBER w13985) has identical values. Splice caveat: Ramey measures women-specific home production ages 18-64; ATUS (2020s room) measures all-adult household activities age 15+ — a concept change that must caveat when plotted together.

Curator note: From Census Table MS-2. Decennial census. Marriage ages held steady through the Depression — men at 24.3, women at 21.3. Economic hardship delayed some marriages but the median barely moved.

National Bureau of Economic Research / Princeton University Press, 1963 · source
Confidence: D — Scholarly estimate
Curator note: From Goldsmith, Lipsey & Mendelson (1963), Table 1, Sector I.1 (Nonfarm households). Total assets: $371B. Tangible assets: $145B. Financial assets: $232B. Debt: $30B. Net worth: $341B. The Depression destroyed ~$65B of household wealth (from $406B in 1929). Financial assets fell from $291B to $232B as stock values collapsed. Debt was actually reduced — from $42B to $30B — as households deleveraged. Aggregate — NOT median.

Provides total assets, tangible assets, financial assets, debt, and net worth in current dollars. Goldsmith's balance sheet construction uses Census wealth data, Federal Reserve flow of funds, and tax return compilations. Aggregate household sector, NOT median. Tier D (scholarly reconstruction).
