View Data Table

Decade-to-decade population change by county has varied greatly in the last century in many parts of the United States. For example, in the 1930s, 1940s, and 1950s, much of eastern Texas saw population decline (signified on the maps by pink shading), but those areas have seen strong population growth since then (signified by green shading). Much of Appalachia, including parts of West Virginia, has seen cycles of population increase and decrease as well.

In the lower-right corner, you can play an animated series of these maps to see how the patterns change over time.
