Value of $100 in 1922, adjusted to 1970

What happened to prices between 1922 and 1970

Between 1922 and 1970, the Consumer Price Index went from 16.8 to 38.8. Cumulatively, prices increased 131.0%, which works out to an average of 1.76% per year. Put differently, a dollar in 1922 bought what $0.43 buys in 1970.

Consumer prices fell another 6.1% in 1922, the second straight year of decline, even as the broader economy climbed out of the Depression of 1920-21 and industrial production rebounded. The CPI had now given back roughly a third of its wartime runup, though it stayed well above the 1913 baseline. Congress moved to shield that recovery from foreign competition: the Fordney-McCumber Tariff Act, signed September 21, raised duties on hundreds of imported goods to some of the highest levels in U.S. history, a policy meant to protect farmers and manufacturers still adjusting to postwar prices. Labor tension flared even as prices fell. Roughly half a million bituminous coal miners struck that April over wage cuts employers had imposed as prices dropped, and hundreds of thousands of railroad shop workers walked out in July in a separate dispute over pay and work rules, together the largest strike wave since 1919. Both disputes dragged on for months and drew federal mediation before ending without full concessions for the workers. First-class postage remained at 2 cents.

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.
