What happened to prices between 1918 and 1969

Between 1918 and 1969, the Consumer Price Index went from 15.1 to 36.7. Cumulatively, prices increased 143.0%, which works out to an average of 1.76% per year. Put differently, a dollar in 1918 bought what $0.41 buys in 1969.

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: 1969

Consumer prices rose 5.5% in 1969, up from 1968’s 4.2% and the fastest pace since the Korean War era, as years of Vietnam War spending, a labor market with unemployment under 4%, and expansionary fiscal policy finally showed up fully in prices. Richard Nixon was inaugurated that January 20, pledging to curb rising prices without wage and price controls, a position he would reverse within two years. The decade’s most triumphant moment came that July 20, when Neil Armstrong and Buzz Aldrin walked on the Moon while Michael Collins orbited above, fulfilling the goal Kennedy had set in 1961 of landing a man on the lunar surface before the decade’s end. Culture and protest both reached new extremes that year: an estimated 400,000 people gathered on a dairy farm in Bethel, New York, for the Woodstock music festival that August, and a police raid on the Stonewall Inn in New York’s Greenwich Village that June touched off days of resistance now credited with launching the modern gay rights movement. Consumer prices finished the decade 270.7% above their 1913 level, up 24.0% from where they stood in 1960. The 1960s had opened with inflation near 1% a year and closed with prices rising faster than at any point since Korea, setting up the Great Inflation that would define the 1970s. First-class postage held at 6 cents, and the minimum wage stayed at $1.60 an hour.
