One paycheck

In 1950 the median four-person family reported $3,675A a year; the median for families of every size was $3,319A. A production worker in manufacturing earned $1.32A an hour across a 40.5A-hour week — ≈ $53.46Acomputed a week, computed by the museum from those two exhibits.

Fifty-two such weeks covered most of the four-person median, and nearly the all-family one. A single paycheck almost carried the median household.

Follow the line forward. The peak it reached after the war never returns; the odd crisis rebound interrupts, but the share ends the chart a third below its postwar level.

By 2024 the implied weekly wage was ≈ $1,225.88Acomputed (the museum's own computation: all-private wages against manufacturing hours) against an all-family median of $105,800A. The paycheck that once reached most of the median now covers barely more than half of it.

One honesty note before the moral. The "one wage" on this line is a manufacturing production wage — urban, industrial, historically male. It stands in for "the worker" only because no broader hourly wage series reaches back across the century; the rooms declare that proxy on the exhibit, rather than hiding it. Conclusions about the median worker should hold that shape in mind.

If one paycheck stopped covering the median, the household's arithmetic had to close another way — and the rooms show where it closed. In 1950 23.8%A of married women were already in the labor force; by the twenty-twenties it was 56.9%A.

The story the line tells is not that work left the family. It is that covering an ordinary life moved — from one wage to two, and from the paid week to the unpaid home. The sister tour, on the work that moved, picks up that thread.
