Value of $100 in 1958, adjusted to 1970

What happened to prices between 1958 and 1970

Between 1958 and 1970, the Consumer Price Index went from 28.9 to 38.8. Cumulatively, prices increased 34.3%, which works out to an average of 2.49% per year. Put differently, a dollar in 1958 bought what $0.74 buys in 1970.

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.

The destination year: 1970

Consumer prices rose 5.7% in 1970, up from 1969’s 5.5%, extending a run of faster price growth that stretched back to the mid-1960s, even as a recession that began in December 1969 pushed unemployment toward 6%. Prices and joblessness rising together confounded the era’s economic thinking, which held that policymakers could trade a little more inflation for a little less unemployment; 1970 was an early sign that trade-off was breaking down, a pattern that would harden into stagflation later in the decade. Washington restructured how it delivered mail that year: after postal workers staged the first strike ever by federal employees that March, Congress passed the Postal Reorganization Act in August, replacing the cabinet-level Post Office Department with the independent U.S. Postal Service. Environmental policy also took shape in 1970. An estimated 20 million Americans marked the first Earth Day on April 22, and the Environmental Protection Agency opened that December to enforce the Clean Air Act and the pollution rules that followed. The Vietnam War kept dividing the country: on May 4, National Guard troops fired on antiwar demonstrators at Kent State University in Ohio, killing four students and setting off strikes on hundreds of campuses. A median household earned $8,734 that year, a gallon of gas averaged 36 cents, and a first-class stamp cost 6 cents, the rate it had held since 1968. Prices stood 291.9% above their 1913 level by the end of 1970, a milestone that would look almost mild against the decade still to come.
