Value of $100 in 1940, adjusted to 1965

What happened to prices between 1940 and 1965

Between 1940 and 1965, the Consumer Price Index went from 14 to 31.5. Cumulatively, prices increased 125.0%, which works out to an average of 3.30% per year. Put differently, a dollar in 1940 bought what $0.44 buys in 1965.

Consumer prices rose 0.7% in 1940, snapping 1939’s decline and marking the first increase since 1937. The gain was modest, and the CPI still stood 18.1% below its 1929 peak, a reminder of how far the recovery from the Depression’s trough had left to go even as defense orders from Britain and France began reaching American factories. War was already reshaping domestic policy well before it touched American soil. Congress passed the Selective Training and Service Act that September, the country’s first peacetime draft, requiring men aged 21 to 35 to register and authorizing the induction of up to 900,000 men a year, more than a year before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented third term, defeating Republican Wendell Willkie after campaigning on keeping the United States out of the war then consuming Europe and Asia. The promise would not hold much longer: within two years, wartime demand would push consumer prices up faster than at any point since the aftermath of World War I. First-class postage held at 3 cents, and the federal minimum wage stayed at 30 cents an hour, the level set the previous October under the Fair Labor Standards Act.

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.
