What happened to prices between 1939 and 1977

Between 1939 and 1977, the Consumer Price Index went from 13.9 to 60.6. Cumulatively, prices increased 336.0%, which works out to an average of 3.95% per year. Put differently, a dollar in 1939 bought what $0.23 buys in 1977.

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending.

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.
