What happened to prices between 1939 and 1966

Between 1939 and 1966, the Consumer Price Index went from 13.9 to 32.4. Cumulatively, prices increased 133.1%, which works out to an average of 3.18% per year. Put differently, a dollar in 1939 bought what $0.43 buys in 1966.

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. First-class postage held at 3 cents.

The destination year: 1966

Consumer prices rose 2.9% in 1966, nearly double 1965’s 1.6% as Vietnam War spending kept climbing without an offsetting tax increase, pushing the economy closer to capacity and prices higher along with it. Medicare coverage took effect that July 1, extending federal health insurance to roughly 19 million Americans age 65 and older under the program signed into law the year before. The Federal Reserve had already moved to cool the overheating economy, raising its discount rate the previous December over White House objections; the tightening carried into 1966 as the first postwar credit crunch, freezing parts of the housing and municipal bond markets even as inflation kept climbing. Congress widened the wage floor’s reach that September 23, when the Fair Labor Standards Amendments of 1966 set a $1.40 minimum wage effective the following February and extended coverage to roughly 9 million more workers in retail, hospitals, schools, and other services not previously covered. Consumer prices finished 1966 227.3% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour for the rest of the year.
