Value of $100 in 1920, adjusted to 1964

What happened to prices between 1920 and 1964

Between 1920 and 1964, the Consumer Price Index went from 20 to 31. Cumulatively, prices increased 55.0%, which works out to an average of 1.00% per year. Put differently, a dollar in 1920 bought what $0.65 buys in 1964.

1920 was the last year of the inflation that had built since the war began: consumer prices rose 15.6% for the year, leaving the CPI more than double its 1913 starting level after seven straight years of increases. The boom behind those increases turned to bust before the year was over. The Federal Reserve, worried about speculation, pushed its discount rate to a record 7% that spring, and wholesale prices, which had led the wartime runup, began collapsing within months. The National Bureau of Economic Research dates the resulting downturn from January 1920 to July 1921, one of the shortest but steepest contractions in U.S. history, and consumer prices followed into outright decline, falling 10.5% in 1921. Two constitutional changes reshaped the country that year, too. The 18th Amendment’s ban on alcohol took legal effect January 17, enforced under the Volstead Act Congress had passed the previous October. Then, on August 18, Tennessee’s ratification of the 19th Amendment secured women’s right to vote nationwide, and women cast ballots in a presidential election for the first time that November, when Warren Harding won on a promise to return the country to “normalcy” after a decade of war, pandemic, and rising prices. First-class postage held at 2 cents, unchanged since mid-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.
