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)
2020s · Tier A
75.8 male, 81.1 female (78.4 total)

Infant mortality

deaths under age 1 per 1,000 live births

1970s · Tier A
20.0 per 1,000 live births
2020s · Tier A
5.6 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)
2020s · Tier A
10.6% (35.9 million people)

Homeownership

% of occupied housing units owner-occupied

1970s · Tier A
62.9%
2020s · Tier A
65.3%

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.
1970s · Tier A
90.5%
2020s · Tier A
Cell phone 92.7%, landline 20.1%, garage/carport 67.6%

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
2020s · Tier A
88% (two-thirds central AC)

Vehicle at home

% of households with a vehicle

⚠ Decennial vehicle data for 1960–2000 is pending curation (WI-8).
1970s · Tier A
80.1% of families had at least one automobile (avg 1.3 per family)
2020s · Tier A
91.5% (8.5% with no vehicle)

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.
1970s · Tier C
32.1
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

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.
1970s · Tier A
Food $2,089/yr (17.1% of expenditure). Food at home $1,543 (74% of food), food away from home $546 (26%). Key items: beef $242, bakery $139, fresh milk $130, pork $134, poultry $69, other meats $61, fish $40, eggs $37, cereals $46. Total expenditure: $12,226.
2020s · Tier A
Food 13.5% of expenditure for 4-person families (~$14,800 of $109,622/yr). Down from 42.54% in 1901.

Consumer Price Index

CPI-U level, 1982–84 = 100

1970s · Tier A
