1970s ↔ 2000s
Fact families the measure guard certifies comparable for this pair. Everything else renders as the gap it is. Every value links to its record.
A median home — affordability
A new car — affordability

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)
2000s · Tier A
74.3 male, 79.7 female (77.0 total, all races)
Infant mortality
deaths under age 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)
2000s · Tier A
11.3% (31.5 million people in poverty)
Homeownership
% of occupied housing units owner-occupied
Average family size
persons per family
⚠ The 1900s datum (5.31) is from the 1901 BLS wage-earner survey — 0.7 persons above the Census 1900 national average of 4.61; the survey over-sampled larger families, not by design.
⚠ The 1940s point is 1947 (first postwar CPS tabulation), not 1940. The 1960s uptick (3.7 vs 3.54 in 1950) reflects the baby boom's peak family-composition effect.
Complete plumbing
% of homes with complete plumbing
1970s · Tier A
94% of homes had complete plumbing (6% lacked)
2000s · Tier A
~99.5% of homes had complete plumbing (~0.5% lacked)
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.
Vehicle at home
% of households with a vehicle
1970s · Tier A
82.5% (17.5% with no vehicle)
2000s · Tier A
89.7% (10.3% with no vehicle); avg 1.9 vehicles per household
Women's unpaid home production
hours per week, prime-age women
⚠ From 2010s onward the source is ATUS (all adults 15+, hrs/day, narrower 'household activities'), not Ramey (prime-age women 18-64, hrs/week, broader 'home production') — a concept splice. ATUS facts remain available in their rooms, but render as linked gaps on this weekly axis rather than as a false decline.
Men's unpaid home production
hours per week, prime-age men
⚠ From 2010s onward the source is ATUS (all adults 15+, hrs/day, narrower 'household activities'), not Ramey (prime-age men 18-64, hrs/week, broader 'home production') — a concept splice. ATUS facts remain available in their rooms, but render as linked gaps on this weekly axis rather than as a false rise or decline.
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.
2000s · Tier A
Food $8,622/yr (13.9% of expenditure). Food at home $4,846 (56% of food), food away from home $3,776 (44%). Key items: meats/poultry/fish/eggs $1,140, fruits/vegetables $780, cereals/bakery $666, dairy $556, beef $344. Total expenditure: $62,215.
Consumer Price Index
CPI-U level, 1982–84 = 100
1970s · Tier A
CPI 38.8 (1970) → 313.7 (2024) = 8.1x. $1 in 1970 = $8.09 in 2024. Real median family income grew 1.33x.
2000s · Tier A
CPI 172.2 (2000) → 313.7 (2024) = 1.8x. $1 in 2000 = $1.82 in 2024. Real median family income grew 1.14x.
Median home size
median sq ft, new single-family houses completed
⚠ 1970s–2020s: median square feet of new single-family houses completed (Census C-25/H-150 / Characteristics of New Housing). The 2020s point is 2024; the series is conceptually consistent across the whole span.
Number of families
families in the United States
⚠ CPS/F-8 counts all families (related persons living together). The 1940s point is 1947 — the first postwar CPS tabulation.
Heart disease mortality
age-adjusted deaths per 100,000
Cancer 5-year relative survival
% surviving 5 years after diagnosis (SEER)
⚠ Different source family (SEER/NCI, not CDC NCHS) and different unit (% surviving, not deaths per 100,000) — not grouped with the mortality arcs.
Healthcare spending as share of GDP
% of GDP (national health expenditures)
Out-of-pocket share of health spending
% of total NHE paid out of pocket
1970s · Tier A
32.7% of national health expenditures paid out of pocket
2000s · Tier A
14.5% of national health expenditures paid out of pocket
Median gross rent
USD/month, nominal (specified renter-occupied units)
⚠ Nominal dollars — the CPI arc and affordability dashboard provide deflation context. No 2010s or 2020s point: Census Historical Housing Tables end at 2000; ACS rent data (Table B25064) would extend the arc in a future curation pass.
Apparel's share of spending
% of total expenditures
⚠ Population changes mid-series: 1970s–1990s are 4-person CUs (CEX Table 4), 2000s–2020s are all consumer units (multi-year tables). Every placard names the measured population.
