What did the Great Migration lead to in terms of demographics?

The Great Migration significantly transformed the demographics of the United States in the early to mid-20th century, primarily by facilitating a large-scale shift of African Americans from rural areas in the South to urban centers in the North. This migration was driven by both push factors, such as Jim Crow laws, economic hardship, and violence in the South, and pull factors, like the promise of better jobs and living conditions in Northern cities. As a result, cities such as Chicago, Detroit, and New York saw significant increases in their African American populations, leading to the establishment of vibrant communities and cultural movements, notably the Harlem Renaissance. This shift not only influenced the demographic composition of urban centers but also had lasting social, economic, and political impacts on both Northern cities and the African American community as a whole.
