What happened to prices between 1918 and 2016

Between 1918 and 2016, the Consumer Price Index went from 15.1 to 240.007. Cumulatively, prices increased 1489.5%, which works out to an average of 2.86% per year. Put differently, a dollar in 1918 bought what $0.06 buys in 2016.

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.
