1940s ↔ 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 1940s 2020s all corridors

A median home — affordability

1940s ↔ 2020s

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

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.

1940s · Tier A

1939-41: 62.8 male, 67.3 female | 1949-51: 66.3 male, 72.0 female — 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.

1940s · Tier A

45.1% (1944) → 61.8% (1950) — 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.

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
