1950s ↔ 1970s
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
1950s · Tier A
~$1,295 (average wholesale, computed from factory sales) ≈ 981 hours of work
1970s · Tier A
$3,543 ≈ 1,097 hours of work
Infant mortality
deaths under age 1 per 1,000 live births
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
1950s · Tier A
64.5% of homes had complete plumbing (35.5% lacked)
1970s · Tier A
94% of homes had complete plumbing (6% lacked)
Household landline telephone
% of households
⚠ The 1900s source combines several technologies in one headline percentage, so its 5% is not plotted as a telephone datum.
⚠ 1910s–1930s sources counted telephones per 1,000 population, not households — those decades render as gaps rather than a unit splice.
1950s · Tier A
Telephone: 61.8% of households (280.9 per 1,000 population). Automobile: registration data available but not asked in 1950 Census.
1970s · Tier A
90.5%
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.
1950s · Tier A
Food $1,309/yr (24.3% of expenditure), housing $1,594 (29.6%), food away from home $274, local telephone $69/yr. Total expenditure: $5,393.
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.
Consumer Price Index
CPI-U level, 1982–84 = 100
1950s · Tier A
24.1
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.
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 mortality
age-adjusted deaths per 100,000
⚠ Six points across nine decades — 1960s, 1980s, and 2000s are missing from the NCHS series and render as gaps.
Stroke mortality
age-adjusted deaths per 100,000
⚠ Only three points span the 70-year window — the decline is dramatic but sparsely sampled. Additional decades are available from the same NCHS source for a future curation pass.
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.
