One paycheck

In 1950 median money income for four-person families was $3,675A a year; the median for families of every size was $3,319A. Manufacturing production workers had average hourly earnings of $1.32A and an average working week of 40.5A hours. Multiplying those rounded averages gives ≈ $53.46Acomputed a week.

These are different statistical populations. The wage is an average across workers; the family median includes money income from the family's earners and other sources. Neither describes a particular household's paycheck or expenses.

The chart uses the published manufacturing weekly-earnings series, multiplied by fifty-two and divided by median all-family money income. That is a benchmark assuming a full year at the average weekly earnings, not observed annual earnings. Changes in the ratio can come from either the wage or the family-income denominator.

The 2024 room also contains ≈ $1,015.04Acomputed, a separate calculation using total-private production and nonsupervisory workers' hourly earnings and weekly hours, beside median all-family income of $105,800A. That broader-sector calculation is not the manufacturing series plotted above and should not be read as its endpoint.

Manufacturing production workers are not all workers, and average earnings are not median earnings. Median family income is not a measure of the cost of an ordinary life. This chart cannot establish whether one earner could support a family, or how common single-earner families were.

Another exhibit records married women's labor force participation: 23.8%A in 1950 and 56.9%A in 2021. The source cards specify their populations. Participation includes both people working and people seeking work; it does not count dual-earner families.

These exhibits place changes in earnings and participation alongside each other. They do not establish that a shortfall in one caused the other. The companion tour considers unpaid work, with its own population and measurement limits.
