Value of $100 in 1957, adjusted to 1970

What happened to prices between 1957 and 1970

Between 1957 and 1970, the Consumer Price Index went from 28.1 to 38.8. Cumulatively, prices increased 38.1%, which works out to an average of 2.51% per year. Put differently, a dollar in 1957 bought what $0.72 buys in 1970.

Consumer prices rose 3.3% in 1957, up from 1956’s 1.5% and the sharpest increase since the Korean War price surge of 1951. The jump fed a growing debate among economists over “cost-push” inflation, prices climbing from rising wages and material costs rather than excess demand, a debate that would recur for the next quarter century. The Federal Reserve tightened policy to fight it, and by August the tighter money combined with falling business investment to tip the economy into a recession, according to the National Bureau of Economic Research’s dating. The Cold War took a technological turn that October, when the Soviet Union launched Sputnik, the first artificial satellite, on the 4th, stunning the American public and setting off both the Space Race and a surge in federal science and defense spending the following year. Civil rights reached a crisis that September in Little Rock, Arkansas: after Governor Orval Faubus used the National Guard to block nine Black students from Central High School, Eisenhower federalized the Guard and sent the 101st Airborne Division to enforce the Supreme Court’s desegregation order. Consumer prices finished 1957 183.8% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stood at $1.00 an hour.

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.
