What happened to prices between 1939 and 1958

Between 1939 and 1958, the Consumer Price Index went from 13.9 to 28.9. Cumulatively, prices increased 107.9%, which works out to an average of 3.93% per year. Put differently, a dollar in 1939 bought what $0.48 buys in 1958.

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending. First-class postage held at 3 cents.

The destination year: 1958

Consumer prices rose 2.8% in 1958, down only slightly from 1957’s 3.3% even as the country sank into the sharpest postwar recession to that point, an early sign that inflation and a shrinking economy could coexist rather than trade off against each other. The National Bureau of Economic Research dates the downturn’s trough to that April, with unemployment peaking near 7.5% that summer, the worst reading since the 1930s. The Post Office raised first-class postage to 4 cents that August 1, up from 3 cents, the rate’s first change since 1932. Washington answered the Soviet Union’s technological lead that summer too: Eisenhower signed the National Aeronautics and Space Act on July 29, establishing NASA, which opened for business that October 1 to compete with the Soviet space program after the shock of Sputnik the year before. Consumer prices finished 1958 191.9% above their 1913 level. The minimum wage held at $1.00 an hour, and first-class postage rose to 4 cents that August, the first increase since 1932.
