What happened to prices between 1970 and 1971

Between 1970 and 1971, the Consumer Price Index went from 38.8 to 40.5. Cumulatively, prices increased 4.4%, which works out to an average of 4.38% per year. Put differently, a dollar in 1970 bought what $0.96 buys in 1971.

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.

The destination year: 1971

Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as the recession that started in December 1969 finally cooled demand. The bigger economic story came that August 15, when President Nixon closed the “gold window” that let foreign governments exchange dollars for gold, ending the Bretton Woods system that had anchored the dollar since World War II. The same address announced a 90-day freeze on wages and prices, the first peacetime controls the country had seen, an attempt to break inflationary expectations without the slower grind of tighter money. The “Nixon Shock,” as it came to be known, let the dollar float against other currencies for the first time and set the stage for a wage-and-price-control regime that would run in various forms into 1973. Politically, the country lowered its voting age that year: the 26th Amendment, ratified July 1, extended the vote to 18-year-olds, capping a campaign built on the argument that men old enough to be drafted to Vietnam were old enough to vote for the people who sent them. The Postal Service, independent since 1970’s reorganization, raised first-class postage from 6 to 8 cents that May. A median household earned $9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents a gallon and a new home sold for a median $25,200. Consumer prices stood 309.1% above their 1913 level by year’s end, still years away from the double-digit inflation the controls were meant to prevent.
