Value of $100 in 1918, adjusted to 1971

What happened to prices between 1918 and 1971

Between 1918 and 1971, the Consumer Price Index went from 15.1 to 40.5. Cumulatively, prices increased 168.2%, which works out to an average of 1.88% per year. Put differently, a dollar in 1918 bought what $0.37 buys in 1971.

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: 1971

Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as the recession that started in December 1969 finally cooled demand. The bigger economic story came that August 15, when President Nixon closed the “gold window” that let foreign governments exchange dollars for gold, ending the Bretton Woods system that had anchored the dollar since World War II. The same address announced a 90-day freeze on wages and prices, the first peacetime controls the country had seen, an attempt to break inflationary expectations without the slower grind of tighter money. The “Nixon Shock,” as it came to be known, let the dollar float against other currencies for the first time and set the stage for a wage-and-price-control regime that would run in various forms into 1973. Politically, the country lowered its voting age that year: the 26th Amendment, ratified July 1, extended the vote to 18-year-olds, capping a campaign built on the argument that men old enough to be drafted to Vietnam were old enough to vote for the people who sent them. The Postal Service, independent since 1970’s reorganization, raised first-class postage from 6 to 8 cents that May. A median household earned $9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents a gallon and a new home sold for a median $25,200. Consumer prices stood 309.1% above their 1913 level by year’s end, still years away from the double-digit inflation the controls were meant to prevent.
