America's economy performed astonishing feats during World War II. Manufacturers retooled their plants to produce war goods. But this alone was not enough. Soon huge new factories, built with government and private funds, appeared around the nation. Millions of new jobs were created and millions of Americans moved to new communities to fill them. Annual economic production, as measured by the Gross National Product (GNP), more than doubled, rising from $99.7 billion in 1940 to nearly $212 billion in 1945.
