What happened to prices between 1921 and 1965

Between 1921 and 1965, the Consumer Price Index went from 17.9 to 31.5. Cumulatively, prices increased 76.0%, which works out to an average of 1.29% per year. Put differently, a dollar in 1921 bought what $0.57 buys in 1965.

Consumer prices fell 10.5% in 1921, the mirror image of the wartime inflation that had more than doubled the cost of living between 1913 and 1920. The Depression of 1920-21, one of the sharpest contractions in U.S. history, bottomed out that July according to the National Bureau of Economic Research, even though it had lasted barely eighteen months. Unemployment climbed toward one worker in ten as businesses cut production and prices to work through wartime inventories, but the same collapse in prices also meant the recovery, once it started, had room to run without reigniting inflation. Warren Harding took office March 4, promising a return to “normalcy” after a decade of war, pandemic, labor unrest, and rapid price swings; his administration moved quickly to cut top income tax rates and federal spending. Congress also acted on immigration that year: the Emergency Quota Act, signed May 19, capped annual arrivals from each country at 3% of that nationality’s population in the 1910 census, the first time the United States had set a numerical ceiling on immigration. The law favored northern and western Europe and cut total immigration by more than half compared with prewar levels; Congress tightened the formula again in 1924. First-class postage held at 2 cents, unchanged since mid-1919.

The destination year: 1965

Consumer prices rose 1.6% in 1965, up from 1964’s 1.3% in a pickup that economists later mark as the start of the Great Inflation, a run of accelerating price increases driven by rising Vietnam War spending layered on top of new Great Society programs. The war itself escalated on the ground that March, when about 3,500 Marines came ashore at Da Nang, the first American combat troops committed to Vietnam; troop levels would climb toward 200,000 by year’s end. Domestic policy expanded just as fast: Medicare and Medicaid became law that July 30, creating federal health insurance for older and low-income Americans, and the Voting Rights Act, signed that August 6, banned literacy tests and other devices used to disenfranchise Black voters. The civil rights movement’s gains coexisted with urban unrest that same August, when a highway patrol traffic stop in the Watts neighborhood of Los Angeles set off six days of rioting that left 34 people dead. Consumer prices finished 1965 218.2% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour.
