Value of $100 in 1917, adjusted to 1963

What happened to prices between 1917 and 1963

Between 1917 and 1963, the Consumer Price Index went from 12.8 to 30.6. Cumulatively, prices increased 139.1%, which works out to an average of 1.91% per year. Put differently, a dollar in 1917 bought what $0.42 buys in 1963.

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: 1963

Consumer prices rose 1.3% in 1963, up slightly from 1962’s 1.0% as the expansion entered its third year with inflation still low, conditions that gave Kennedy room to push the large tax cut he had proposed to Congress. The cost of a first-class stamp rose that January 7, to 5 cents from 4 cents, the first postal rate change since 1958. That August 28, Martin Luther King Jr. delivered his “I Have a Dream” speech from the steps of the Lincoln Memorial to a quarter million people gathered for the March on Washington, building pressure on Congress to pass the civil rights bill Kennedy had proposed that June. The year ended in tragedy: Kennedy was assassinated while riding in a motorcade through Dallas on November 22, and Lyndon B. Johnson was sworn in aboard Air Force One that same afternoon. Johnson would spend the following year pushing Kennedy’s stalled tax and civil rights agenda through Congress. The minimum wage rose again that September, to $1.25 an hour, the second step of the phased increase set two years earlier. Consumer prices finished 1963 209.1% above their 1913 level.
