What happened to prices between 1940 and 1977

Between 1940 and 1977, the Consumer Price Index went from 14 to 60.6. Cumulatively, prices increased 332.9%, which works out to an average of 4.04% per year. Put differently, a dollar in 1940 bought what $0.23 buys in 1977.

Consumer prices rose 0.7% in 1940, snapping 1939’s decline and marking the first increase since 1937. The gain was modest, and the CPI still stood 18.1% below its 1929 peak, a reminder of how far the recovery from the Depression’s trough had left to go even as defense orders from Britain and France began reaching American factories. War was already reshaping domestic policy well before it touched American soil. Congress passed the Selective Training and Service Act that September, the country’s first peacetime draft, requiring men aged 21 to 35 to register and authorizing the induction of up to 900,000 men a year, more than a year before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented third term, defeating Republican Wendell Willkie after campaigning on keeping the United States out of the war then consuming Europe and Asia. The promise would not hold much longer: within two years, wartime demand would push consumer prices up faster than at any point since the aftermath of World War I. First-class postage held at 3 cents, and the federal minimum wage stayed at 30 cents an hour, the level set the previous October under the Fair Labor Standards Act.

The destination year: 1977

Consumer prices rose 6.5% in 1977, ticking back up from 1976’s 5.8% as the economic recovery strengthened, wages climbed, and energy costs pushed higher again. The year opened with a warning about that energy dependence: record cold across the Midwest and Northeast in January and February strained natural gas supplies so badly that schools and factories in several states shut down for days to conserve fuel. Jimmy Carter, inaugurated that January, made energy policy a centerpiece of his presidency, and Congress created the cabinet-level Department of Energy that August to consolidate programs built up piecemeal since the 1973 oil embargo. Culture offered some relief from the anxiety: released that May, Star Wars became the highest-grossing film in history to that point, drawing lines around theater blocks for months. The year also closed an era in a different way. Elvis Presley was found dead at his Graceland home on August 16 at age 42, drawing tens of thousands of mourners to Memphis. A median household earned $13,572 in 1977, a new home sold for a median $48,800, and gas averaged 62 cents a gallon. Consumer prices stood 512.1% above their 1913 level, with the energy anxieties of the year setting up the harder shocks of 1978 and 1979.
