What happened to prices between 1918 and 1964

Between 1918 and 1964, the Consumer Price Index went from 15.1 to 31. Cumulatively, prices increased 105.3%, which works out to an average of 1.58% per year. Put differently, a dollar in 1918 bought what $0.49 buys in 1964.

1918 brought the steepest annual price increase the CPI had recorded: consumer prices rose 18.0% for the year, edging out 1917’s already sharp 17.4% as the economy stayed at full wartime mobilization for most of the year. A first-class stamp cost 3 cents, up from 2 cents the previous November under the War Revenue Act’s wartime tax increases. The war itself ended on November 11, when Germany signed an armistice with the Allied powers after more than four years of fighting in Europe, but the inflation built up over a year and a half of mobilization did not disappear along with the fighting. The bigger public health story that year was the influenza pandemic that reached the U.S. in a mild spring wave and then returned that fall in a far deadlier form, eventually killing roughly 675,000 Americans, more than the country’s combat losses in the war. It hit factories, docks, and shops alongside households, adding disruption to an economy already strained by wartime demand. Prices would keep climbing even after the armistice, into the postwar surge of 1919.

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.
