1900s ↔ 1950s
Fact families the measure guard certifies comparable for this pair. Everything else renders as the gap it is. Every value links to its placard.
Infant mortality
deaths under age 1 per 1,000 live births
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.
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.
Men's unpaid home production
hours per week, prime-age men
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.
