What happened to prices between 1918 and 1950

Between 1918 and 1950, the Consumer Price Index went from 15.1 to 24.1. Cumulatively, prices increased 59.6%, which works out to an average of 1.47% per year. Put differently, a dollar in 1918 bought what $0.63 buys in 1950.

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: 1950

Consumer prices rose 1.3% in 1950, up from 1949’s 1.2% decline, a mild gain that hid a sharp turn partway through the year. The cost of living had been roughly flat through the spring, then jumped after North Korea invaded South Korea on June 25, setting off a wave of hoarding and defense buying reminiscent of World War II shortages. The United States entered the war within days under a United Nations mandate; American and South Korean forces were pushed back to the Pusan Perimeter that summer before a landing at Inchon that September reversed the front, and China’s entry into the war that November turned it into a longer stalemate. Congress moved to put the economy on a war footing that September, passing the Defense Production Act, which gave the president authority to direct industrial output toward the military and, if prices kept climbing, to impose formal wage and price controls. Domestic policy also expanded that year: the Social Security Amendments of 1950, signed August 28, raised benefits across the board and extended coverage to roughly 10 million more workers, the program’s first major expansion since it began in 1935. Consumer prices finished 1950 143.4% above their 1913 level, matching 1948’s postwar high after 1949’s brief decline. First-class postage held at 3 cents, and the minimum wage stood at 75 cents an hour after January’s increase.
