1930s ↔ 2020s

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 1930s 2020s 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.

1930s · Tier A

59.1 male, 62.7 female (white) — see the placard

2020s · Tier A

75.8 male, 81.1 female (78.4 total)

Homeownership

% of occupied housing units owner-occupied

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.

1930s · Tier A

~41 per 1,000 population (1935) — see the placard

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.

1930s · Tier C

43.2

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
