Migration did not simply move people. It reshaped housing, wealth, education, employment, health, and political power — each system influencing the next.

What do we know, how do we know it, and what comes next?
The Great Migration was one of the largest internal migrations in American history. Between 1916 and 1970, approximately 6 million Black Americans left the rural South for Northern, Midwestern, and Western cities, fundamentally reshaping the demographic, political, and cultural landscape of the United States.
Population quadrupled in 60 years
The Black population grew from 8.8 million in 1900 to 41.5 million in 2020, driven by both natural increase and migration patterns.
The South reversed its outflow
After decades of net out-migration, the South became the primary destination for Black Americans starting in the 1970s — a reverse migration that continues today.
Urban concentration accelerated
By 2020, 56 metropolitan areas had Black populations exceeding 100,000, concentrated in the South and Northeast.
Migration shaped political power
The concentration of Black voters in Northern cities directly influenced the passage of civil rights legislation in the 1960s.
