Population decline has occurred in the majority of U.S. counties, and those declined counties included over half the population of the United States 60 years ago. Today, fully a quarter of Americans live in counties below their peak population. However, that number can exaggerate the prevalence of ongoing decline: only 396 counties hit their minimum population in 2015, and they accounted for just 4 million people in 2015, versus about 7 million in 1940: from 5.3% of the nation to 1.3%.

Population decline has been concentrated in small, rural counties, former coal-producing areas, and urban centers. Of those categories, urban centers have shown some recent strength in some cases, while rural areas and coal-counties have been far less likely to show any sign of recovery.
