Curator note: From Historical Statistics of the United States, Series D 766 (hourly earnings). The anchor year is 1908 ($0.250/hr = 25 cents, exact) because the 1900 figure ($0.216/hr) is not representable in integer cents — per Plan 013 D2, the anchor picks the in-decade year whose published figure lands on a cent boundary. Weekly earnings: $0.250 x 56.8 hrs = $14.20. The 1900 figure ($0.216, 59.0 hrs, $12.74/wk) is the decade's start; 1908 is mid-decade. The 8-year gap to the income anchor (1900-01) is flagged by the affordability comparator.

Down from 45.3% lacking in 1940 to 35.5% lacking in 1950 (15,772,717 of 44,502,192 occupied units) — the postwar building boom and suburban expansion were starting to close the gap, but more than one in three American homes still lacked complete plumbing. Rural areas lagged badly. By 1960: 16.8% lacked (83.2% had). Figures verified against the Census time-series file 2026-07-07.
Source note: Complete plumbing = hot and cold piped water + flush toilet + bathtub/shower for exclusive use.

Confidence: C — Reconstructed from period surveys
Curator note: Concept splice (Plan 004 Measure guard): Ramey measures unpaid home production (food prep, cleaning, clothing care, childcare, purchasing, management) for prime-age women and men separately, ages 18-64, in hours/week. ATUS (us-2020s-time-use, source bls-atus, 2024 annual averages) measures 'household activities' for all adults 15+ in hrs/day, without gender breakdown in the headline figure. The two series are NOT directly comparable: (1) different activity definitions (Ramey's 'home production' is broader than ATUS 'household activities'), (2) different populations (prime-age vs all-adult), (3) different units (weekly vs daily). When plotted on the same axis, this splice must carry a caveat banner. The Ramey series is the thesis spine (women's hours falling); ATUS is the modern anchor point.

CORRECTION 2026-07-07: this fact previously displayed 17.8%, a misread of Table 1400's aggregate-share column (the share of NATIONAL food spending attributable to 4-person CUs — they are 12.3% of CUs and outspend the average, so their aggregate shares cluster at 15-18% in every category); that column is not a budget share. Compared to 1901: food dropped from 42.54% to 13.5% — Engel's Law in action.

Confidence: D — Scholarly estimate
Curator note: Ramey (2009) does not report a 1990s benchmark. She explicitly excludes the 1992-94 time use survey ('I do not use the 1992-94 survey because of key missing data such as marital status and the problems with that survey discussed by Robinson and Godbey'). The series jumps from 1985 (28.4 hrs) to 2003 (29.7 hrs). Interpolation would be misleading given the non-monotonic trend. ATUS begins 2003 but measures all adults, not women-specifically.

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).

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.

American Time Use Survey (ATUS)

Confidence: A — Official series
Curator note: From ATUS Table A-1 (2010 annual averages), a1_2010.pdf. 'Household activities' = 2.14 hrs/day for women (includes housework, food prep/cleanup, lawn/garden, household management). Cross-verified against Table A-2 (a2_2010.pdf): weekday 2.05 + weekend 2.38, weighted (5×2.05+2×2.38)/7 = 2.144 ≈ 2.14. Concept splice (Plan 004 Measure guard): Ramey measures 'home production' (broader: includes childcare, purchasing) for prime-age women 18-64 in hrs/week; ATUS measures 'household activities' (narrower) for all women 15+ in hrs/day. The quantity is hrs/day (the source's own unit); the arc chart plots it alongside Ramey's hrs/week values — the visual discontinuity reflects the concept splice, flagged by the arc caveat. The 2020s room carries the 2024 ATUS endpoint (us-2020s-home-production-splice).
