What happened
Full recovery came only with the Second World War. Federal Reserve historians mark the Depression as ending in 1941, with a return to full output and employment during the war. As the United States mobilized, war spending surged: in 1942 alone the military more than doubled, from 1.8 million to 3.9 million people, pulling the remaining unemployed workers of military age into service, and the government awarded over 100 billion dollars in military contracts in the first six months. Factories that had sat idle ran around the clock building weapons, and businesses raised wages to compete for the workers who were suddenly scarce.
Why it matters
The wartime boom settled, in practice, the debate over how to end a depression by demonstrating what enormous public spending could do to demand and employment. Whether that lesson credits Keynesian fiscal policy or simply reflects the unique scale of war mobilization is still argued, but the timing is not in dispute: the joblessness of the 1930s vanished once the government began spending on the war.
How we know
The end date is stated in the Federal Reserve History overview of the Depression, and the wartime surge in military employment and contracts is documented by the National Park Service account of the World War II home front economy.
