Great Migration Swells Harlem and Northern Cities in Early 1920s

In the early 1920s, the Great Migration of African Americans from the rural South to Northern and Midwestern cities accelerated, bringing over a million Black migrants to New York, Chicago, Detroit, and Pittsburgh. In Harlem specifically, the Black population grew from under 50,000 in 1910 to over 175,000 by 1925. This demographic transformation created the audience, the consumer base, and the cultural critical mass that made the Harlem Renaissance possible.
