Value of $100 in 1918, adjusted to 1963

What happened to prices between 1918 and 1963

Between 1918 and 1963, the Consumer Price Index went from 15.1 to 30.6. Cumulatively, prices increased 102.6%, which works out to an average of 1.58% per year. Put differently, a dollar in 1918 bought what $0.49 buys in 1963.

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: 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.
