Value of $100 in 1963, adjusted to 1970

What happened to prices between 1963 and 1970

Between 1963 and 1970, the Consumer Price Index went from 30.6 to 38.8. Cumulatively, prices increased 26.8%, which works out to an average of 3.45% per year. Put differently, a dollar in 1963 bought what $0.79 buys in 1970.

Consumer prices rose 1.3% in 1963, up slightly from 1962’s 1.0% as the expansion entered its third year with inflation still low, conditions that gave Kennedy room to push the large tax cut he had proposed to Congress. The cost of a first-class stamp rose that January 7, to 5 cents from 4 cents, the first postal rate change since 1958. That August 28, Martin Luther King Jr. delivered his “I Have a Dream” speech from the steps of the Lincoln Memorial to a quarter million people gathered for the March on Washington, building pressure on Congress to pass the civil rights bill Kennedy had proposed that June. The year ended in tragedy: Kennedy was assassinated while riding in a motorcade through Dallas on November 22, and Lyndon B. Johnson was sworn in aboard Air Force One that same afternoon. Johnson would spend the following year pushing Kennedy’s stalled tax and civil rights agenda through Congress. The minimum wage rose again that September, to $1.25 an hour, the second step of the phased increase set two years earlier. Consumer prices finished 1963 209.1% above their 1913 level.

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.
