African Americans settled in the slum and ghettos of the Northern side changing the demographics of the cities.
Explanation:
Places like Harlem in New York and Compton in California where there were very low income areas settled by predominantly black people in otherwise bludgeoning economies where they became slums is a characteristic of this migration.
