1990s ↔ 2010s
Fact families the measure guard certifies comparable for this pair. Everything else renders as the gap it is. Every value links to its placard.
A median home — affordability
1990s ↔ 2010s
not comparable for this pair — the hours axis needs a structured price and a verified wage anchor in both rooms — not yet curated for this pair
Budget composition
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.
Infant mortality
deaths under age 1 per 1,000 live births
People in poverty
% below the official poverty line
⚠ The official poverty series begins in 1959 — earlier decades have no line.
Homeownership
% of occupied housing units owner-occupied
Air conditioning
% of households with AC
⚠ The 1980s source bridges 1978 central-AC and 1993 total-AC figures — no single-decade datum, so the decade renders as a gap.
Cable television
% of TV households
⚠ The 2010s source reports subscriber counts amid cord-cutting, not a share.
Internet at home
% of households
⚠ 1990s–2010s sources report within-decade ranges; the placards carry them and the chart renders the gaps.
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.
Men's unpaid home production
hours per week, prime-age men
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.
