1920s ↔ 2000s

Fact families the measure guard certifies comparable for this pair. Everything else renders as the gap it is. Every value links to its placard.

Rooms 1920s 2000s all corridors

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.

1920s · Tier A

56.3 male, 58.5 female (white) — see the placard

2000s · Tier A

74.3 male, 79.7 female (77.0 total, all races)

Homeownership

% of occupied housing units owner-occupied

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
