Value of $100 in 1918, adjusted to 1935

What happened to prices between 1918 and 1935

Between 1918 and 1935, the Consumer Price Index went from 15.1 to 13.7. Cumulatively, prices declined 9.3%, which works out to an average of -0.57% per year. Put differently, a dollar in 1918 bought what $1.10 buys in 1935.

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: 1935

Consumer prices rose 2.2% in 1935, a second straight annual increase after 1934’s turnaround, though the CPI still sat well below its 1929 peak and the recovery remained uneven and incomplete. The year’s biggest legislative achievements aimed at making that unevenness less punishing. Roosevelt signed the Social Security Act on August 14, creating federal old-age pensions and unemployment insurance funded by a new payroll tax, the first federal safety net of its kind in U.S. history. That spring, the Works Progress Administration had already begun putting millions of unemployed Americans to work on public construction, arts, and infrastructure projects, becoming the largest jobs program of the New Deal. Congress added labor protections to the mix that July with the National Labor Relations Act, guaranteeing most private-sector workers the right to organize and bargain collectively. The human cost of the Dust Bowl was still mounting on the Plains: the storm known as Black Sunday hit on April 14, one of the worst of the decade, and continued drought kept driving farm families off land that could no longer support them. Consumer prices ended the year 38.4% above their 1913 level. First-class postage held at 3 cents.
