Value of $100 in 1914, adjusted to 1970

What happened to prices between 1914 and 1970

Between 1914 and 1970, the Consumer Price Index went from 10 to 38.8. Cumulatively, prices increased 288.0%, which works out to an average of 2.45% per year. Put differently, a dollar in 1914 bought what $0.26 buys in 1970.

Consumer prices barely moved in 1914, rising just 1.0% for the year, even as the country’s financial plumbing was rebuilt from the ground up. The Federal Reserve Banks, created by the Federal Reserve Act signed the previous December, opened their doors on November 16, giving the U.S. a central bank for the first time since the 1830s. Weeks earlier, the outbreak of war in Europe had spooked the New York Stock Exchange into closing for more than four months, the longest shutdown in its history, as officials worried European investors would dump American securities for gold. Domestically, the bigger story was labor: Henry Ford’s decision to pay factory workers $5 a day, announced in January, roughly doubled wages on his assembly lines and pushed other manufacturers to raise pay just to keep workers from leaving. A first-class stamp still cost 2 cents, a price that had held since 1885 and would keep holding for three more years, even as the war reshaping Europe began pulling the American economy toward the sustained wartime inflation of 1917.

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.
