Value of $100 in 1917, adjusted to 1972

What happened to prices between 1917 and 1972

Between 1917 and 1972, the Consumer Price Index went from 12.8 to 41.8. Cumulatively, prices increased 226.6%, which works out to an average of 2.18% per year. Put differently, a dollar in 1917 bought what $0.31 buys in 1972.

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: 1972

Consumer prices rose just 3.2% in 1972, the calmest year of the decade and a sharp break from the previous two years. The relief was largely engineered: Nixon’s wage and price controls, imposed as a 90-day freeze in August 1971, had settled into a series of “phases” that capped how much businesses could raise prices through the election year. Economists would later argue the controls mostly deferred inflation rather than curing it, storing up pressure that broke loose once they were lifted. Nixon spent political capital on foreign policy that year, traveling to Beijing that February in the first visit by a sitting U.S. president to the People’s Republic of China, a trip that began normalizing relations Washington had frozen since 1949. Closer to home, five men were arrested breaking into the Democratic National Committee’s offices at the Watergate complex that June 17, an event that drew little attention at the time but would eventually force Nixon from office. None of it dented his re-election bid: Nixon carried 49 states against Democrat George McGovern that November, helped by an economy that, on paper, looked more stable than it had in years. A median household earned $9,697 in 1972, a new home sold for a median $27,600, and gas held near 36 cents a gallon for a third straight year. Consumer prices stood 322.2% above their 1913 level, a lull that would not survive contact with the controls’ expiration and the oil shock still to come.
