Saginaw became the destination for a great number of workers migrating from areas of the United States that were greatly devastated by the Great Depression, especially from the south. This migration continued throughout the war years and in the economic boom, which followed. Saginaw, like most of America, benefited from the dramatic economic prosperity following the war. General Motors expanded its presence in Saginaw, and other manufacturers increased production as well. This caused the population of the City to swell to its height of approximately 100,000 during the 1960s.
