What happened to prices between 1917 and 1967

Between 1917 and 1967, the Consumer Price Index went from 12.8 to 33.4. Cumulatively, prices increased 160.9%, which works out to an average of 1.94% per year. Put differently, a dollar in 1917 bought what $0.38 buys in 1967.

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: 1967

Consumer prices rose 3.1% in 1967, up from 1966’s 2.9% as Vietnam War spending kept climbing alongside expanding Great Society programs, a combination of rising military and domestic outlays that economists later blamed for entrenching inflation through the rest of the decade. The minimum wage rose that February 1, to $1.40 an hour, the first step of a phased increase Congress had set the year before. Urban unrest reached a peak that July, when days of rioting left 26 dead in Newark and 43 dead in Detroit, the deadliest of that summer’s roughly 160 disturbances; Johnson responded by forming the Kerner Commission to study the causes of the unrest. The Supreme Court gained its first Black justice that year too: the Senate confirmed Thurgood Marshall on August 30, and he was sworn in that October after serving as U.S. Solicitor General and, before that, as the lead attorney in Brown v. Board of Education. Consumer prices finished 1967 237.4% above their 1913 level. First-class postage held at 5 cents.
