The significant effect of the Northern migration of African Americans between 1910 and 1930 was a 40% increase in population in many Northern cities. This period, known as the Great Migration, saw a substantial movement of African Americans from the rural South to urban centers in the North seeking better economic opportunities and escaping the oppressive conditions of Jim Crow laws.

As African Americans settled in cities like Chicago, Detroit, and New York, they not only contributed to the workforce but also transformed the demographic landscape of these areas. This migration resulted in cultural changes, including the flourishing of the Harlem Renaissance in New York, where African American art, music, and literature thrived.

The migration did not lead to a decline in population, nor did it reduce job competition; in fact, it often intensified competition for jobs as many migrated individuals sought employment in industrial sectors during a time of economic growth. Additionally, while there were some who returned to the South, the overall trend during this period was one of relocation to the North rather than a return. The significant increase in population reflects the impact of this mass movement on American society.
