Answer:
The migration from the rural South to the urban North had on African Americans.
Step-by-step explanation:
The Great Migration occurred when African Americans decided to leave the South from 1916 to 1970. Millions of African Americas began to leave rural areas in the Southern states and move to Northern cities. The racial discrimination led to the changes in economic, political and social for African Americas.
Some of the effects of the great migrations included increased population in northern cities. People had to work in factories and butcheries where working was dangerous. There was a growing competition for jobs. Racism was extensive in the North due to differences which developed crime rate and alcohol drinking among the African Americans.
