What happened to prices between 1939 and 2007
Between 1939 and 2007, the Consumer Price Index went from 13.9 to 207.342. Cumulatively, prices increased 1391.7%, which works out to an average of 4.05% per year. Put differently, a dollar in 1939 bought what $0.07 buys in 2007.
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.
