What happened to prices between 1918 and 1972

Between 1918 and 1972, the Consumer Price Index went from 15.1 to 41.8. Cumulatively, prices increased 176.8%, which works out to an average of 1.90% per year. Put differently, a dollar in 1918 bought what $0.36 buys in 1972.

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: 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.
