What happened to prices between 1964 and 1970

Between 1964 and 1970, the Consumer Price Index went from 31 to 38.8. Cumulatively, prices increased 25.2%, which works out to an average of 3.81% per year. Put differently, a dollar in 1964 bought what $0.80 buys in 1970.

Consumer prices rose 1.3% in 1964, matching 1963’s pace even as a large federal tax cut took effect that year. The Revenue Act of 1964, signed February 26, lowered individual and corporate tax rates significantly, the cut Kennedy had proposed the year before his death and Johnson pushed through Congress as a Keynesian bet that lower taxes would spur enough growth without stoking prices. Congress reshaped civil rights law that July 2, when the Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, and national origin in employment and public accommodations, the most sweeping civil rights legislation since Reconstruction. Vietnam policy shifted that August, when Congress passed the Gulf of Tonkin Resolution after reported attacks on U.S. Navy destroyers, authorizing Johnson to use military force in Vietnam without a formal declaration of war. American pop culture changed that February too: the Beatles landed at New York’s Kennedy Airport and played the Ed Sullivan Show two days later for an estimated 73 million viewers, igniting the “British Invasion.” Consumer prices finished 1964 213.1% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 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.
