Value of $100 in 1939, adjusted to 1957

What happened to prices between 1939 and 1957

Between 1939 and 1957, the Consumer Price Index went from 13.9 to 28.1. Cumulatively, prices increased 102.2%, which works out to an average of 3.99% per year. Put differently, a dollar in 1939 bought what $0.49 buys in 1957.

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: 1957

Consumer prices rose 3.3% in 1957, up from 1956’s 1.5% and the sharpest increase since the Korean War price surge of 1951. The jump fed a growing debate among economists over “cost-push” inflation, prices climbing from rising wages and material costs rather than excess demand, a debate that would recur for the next quarter century. The Federal Reserve tightened policy to fight it, and by August the tighter money combined with falling business investment to tip the economy into a recession, according to the National Bureau of Economic Research’s dating. The Cold War took a technological turn that October, when the Soviet Union launched Sputnik, the first artificial satellite, on the 4th, stunning the American public and setting off both the Space Race and a surge in federal science and defense spending the following year. Civil rights reached a crisis that September in Little Rock, Arkansas: after Governor Orval Faubus used the National Guard to block nine Black students from Central High School, Eisenhower federalized the Guard and sent the 101st Airborne Division to enforce the Supreme Court’s desegregation order. Consumer prices finished 1957 183.8% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stood at $1.00 an hour.
