Before and After 1940:

Change in Population Density

Metadata

Abstract

County-level population change for the 1930s differed from the 1920s or the 1940s, as shown in this set of three maps. In the 1920s, a number of predominantly rural counties in the nation's eastern half saw declines in population and population density, often reflecting outmigration to cities. During the 1930-1940 decade the pattern reversed, with population and population density declines primarily located in the Great Plains. Between 1935 and 1940, 12 percent of the population moved to another county or state. This represented a lull in population movement that changed during and after WWII as geographic mobility increased in the U.S. For instance, between 1940 and 1947, 21.5 percent of civilians moved to different counties or states. In the 1940-1950 period, population density increased for the more urban and populous counties in the Northeast and Midwest, but declines were widespread in predominantly rural counties.
