1970s ↔ 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.

Rooms 1970s 2010s all corridors

A median home — affordability

1970s ↔ 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.

1970s · Tier A

67.1 male, 74.8 female (70.8 total, all races)

2010s · Tier A

76.2 male, 81.0 female (78.7 total, all races)

Infant mortality

deaths under age 1 per 1,000 live births

1970s · Tier A

20.0 per 1,000 live births

2010s · Tier A

6.1 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.

1970s · Tier A

12.6% (25.5 million people in poverty)

2010s · Tier A

15.1% (46.2 million people in poverty)

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.

1970s · Tier A

23% of households had central AC

2010s · Tier A

87% of homes had AC (64% central AC)

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.
