Value of $100 in 1915, adjusted to 1964

What happened to prices between 1915 and 1964

Between 1915 and 1964, the Consumer Price Index went from 10.1 to 31. Cumulatively, prices increased 206.9%, which works out to an average of 2.32% per year. Put differently, a dollar in 1915 bought what $0.33 buys in 1964.

Consumer prices rose 1.0% in 1915, the second straight year of near-flat inflation before the wartime price surges of 1916 through 1918. The year’s defining event had nothing to do with prices directly: a German submarine sank the British liner Lusitania off the Irish coast on May 7, killing 128 Americans and hardening U.S. opinion against Germany two years before the country entered the war. Economically, 1915 was a turning point of a different kind. A recession that had dragged on since 1913 began lifting as Britain and France placed growing orders for steel, munitions, and other war materiel with American manufacturers, and U.S. exports to the Allied powers climbed sharply through the year. That demand would keep building through 1916, eventually pulling prices up with it. On the regulatory side, the Federal Trade Commission opened for business in March, taking on enforcement of the Clayton Antitrust Act that Congress had passed the previous fall. A first-class stamp still cost 2 cents, unchanged since 1885 and still two years from its first wartime increase.

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.
