The Great Migration played a major role in forming new communities in the North because it resulted in a large influx of African American migrants who left the South in search of better job opportunities and a higher quality of life. These new communities in the North were often populated by African Americans and other minority groups, and were often characterized by tight-knit neighborhoods, vibrant cultural and social scenes, and a strong sense of community. These new communities often formed in large cities such as Chicago, Detroit, Philadelphia, and New York, and provided a place for African Americans to find work, build their own businesses, and express their culture. This influx of African Americans to the North also contributed to an increase in the population of African Americans in the North, which in turn led to a greater number of African American-owned businesses, churches, and other organizations.
