South Region USA Regions Population

Largest and fastest-growing U.S. region.

The South Region of the United States has experienced a profoundly dynamic demographic history, evolving from its colonial origins to become a major engine of national population growth. Historically, its population was shaped by the forced migration of enslaved Africans and later by the widespread out-migration of African Americans during the Great Migration throughout the early and mid-20th century, which saw millions leave for northern and western cities. However, the latter half of the 20th century marked a significant reversal, as the region transformed into a quintessential Sun Belt destination, attracting residents with its growing job markets, warmer climate, and relatively lower cost of living. Today, the South is characterized by robust in-migration from other U.S. regions, particularly the Northeast and Midwest, as well as substantial international immigration, leading to rapid diversification and urbanization, making it the fastest-growing region in the nation and continuously reshaping its cultural and economic landscape.
