Value of $100 in 1917, adjusted to 1950

What happened to prices between 1917 and 1950

Between 1917 and 1950, the Consumer Price Index went from 12.8 to 24.1. Cumulatively, prices increased 88.3%, which works out to an average of 1.94% per year. Put differently, a dollar in 1917 bought what $0.53 buys in 1950.

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: 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.
