Life expectancy at birth

years (all races, both sexes)

⚠ Decades before the 1960s published white-only male/female life tables with no all-races total — the placard carries the sexed figures and the chart renders the gap rather than a spliced concept.
1900s · Tier A
48.2 years (white male), 51.1 years (white female) — see the placard
2020s · Tier A

Homeownership

2020s · Tier A

Telephone

% of households

⚠ 1910s–1930s sources counted telephones per 1,000 population, not households — those decades render as gaps rather than a unit splice.
⚠ The 2020s point counts cell phones (92.7%); the landline share is on the placard.
1900s · Tier A
Telephone: 9.2 per 1,000 population (1898), ~5% of households. Automobile: <1% (registration incomplete pre-1910). Electricity: <5% of homes (urban only). Radio: not yet commercial.
2020s · Tier A
Cell phone 92.7%, landline 20.1%, garage/carport 67.6%

Women's unpaid home production

hours per week, prime-age women

⚠ The 2020s source (ATUS) measures all-adult household activities, a concept splice from Ramey's women's series — flagged, not smoothed, so the chart renders it as a gap and the placard carries both figures.
1900s · Tier C

2020s · Tier C
Ramey 2005: women 29.3, men 16.8 hrs/week (ages 18–64) → ATUS 2019: household activities 1.78 hrs/day, all adults 15+ — see the placard

Food's share of spending

% of household expenditure

⚠ Populations differ across the century — 1901 wage-earner families vs modern consumer units; every placard names who was measured.
⚠ The 1950s point is the nearest available survey (CEX 1960–61), stated plainly rather than back-cast.
1900s · Tier A
42.54%
2020s · Tier A
Food 13.5% of expenditure for 4-person families (~$14,800 of $109,622/yr). Down from 42.54% in 1901.
