Value of $100 in 1917, adjusted to 1964

What happened to prices between 1917 and 1964

Between 1917 and 1964, the Consumer Price Index went from 12.8 to 31. Cumulatively, prices increased 142.2%, which works out to an average of 1.90% per year. Put differently, a dollar in 1917 bought what $0.41 buys in 1964.

1917 is when World War I inflation stopped being a background trend and became the dominant fact of American economic life. Consumer prices rose 17.4% for the year, more than double the previous year’s already sharp increase, as the country’s April 6 entry into the war layered federal war spending on top of an economy already strained by military demand and worker shortages. Congress paid for the war with the War Revenue Act that October, which sharply raised income taxes, created a new tax on wartime business profits, and, in a small but very visible change for ordinary households, raised the cost of a first-class stamp from 2 cents to 3 cents that November, the rate’s first move since 1885. Herbert Hoover took over the new Food Administration in August and asked Americans to conserve food voluntarily rather than face formal rationing, a campaign that became famous enough that “Hooverize” entered the language as a verb for cutting back. None of it slowed prices much: the 17.4% increase would be topped again the very next year, in 1918.

The destination year: 1964

Consumer prices rose 1.3% in 1964, matching 1963’s pace even as a large federal tax cut took effect that year. The Revenue Act of 1964, signed February 26, lowered individual and corporate tax rates significantly, the cut Kennedy had proposed the year before his death and Johnson pushed through Congress as a Keynesian bet that lower taxes would spur enough growth without stoking prices. Congress reshaped civil rights law that July 2, when the Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, and national origin in employment and public accommodations, the most sweeping civil rights legislation since Reconstruction. Vietnam policy shifted that August, when Congress passed the Gulf of Tonkin Resolution after reported attacks on U.S. Navy destroyers, authorizing Johnson to use military force in Vietnam without a formal declaration of war. American pop culture changed that February too: the Beatles landed at New York’s Kennedy Airport and played the Ed Sullivan Show two days later for an estimated 73 million viewers, igniting the “British Invasion.” Consumer prices finished 1964 213.1% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour.
