Value of $100 in 1918, adjusted to 1961

What happened to prices between 1918 and 1961

Between 1918 and 1961, the Consumer Price Index went from 15.1 to 29.9. Cumulatively, prices increased 98.0%, which works out to an average of 1.60% per year. Put differently, a dollar in 1918 bought what $0.51 buys in 1961.

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: 1961

Consumer prices rose 1.0% in 1961, down from 1960’s 1.7% as the economy climbed out of recession, a recovery the National Bureau of Economic Research dates to that February. Politically, the year opened with a changing of the guard: outgoing president Dwight Eisenhower’s farewell address on January 17 warned of a growing “military-industrial complex,” and three days later John F. Kennedy was sworn in, urging Americans to “ask not what your country can do for you.” The new administration’s first major foreign-policy test came quickly and badly: a CIA-organized force of Cuban exiles landed at the Bay of Pigs on April 17 aiming to topple Fidel Castro, and without the U.S. air support Kennedy withheld, the invasion collapsed within three days. Cold War tensions hardened further that August, when East German forces sealed the border between East and West Berlin overnight, building what would become the Berlin Wall and stopping the flow of refugees to the West. Domestically, the wage floor moved for the first time in five years: the Fair Labor Standards Amendments of 1961, effective that September, raised the minimum wage to $1.15 an hour and extended coverage to roughly 3.6 million additional workers. Consumer prices finished 1961 202.0% above their 1913 level. First-class postage held at 4 cents.
