Also known as the Great Northward Migration and the Black Migration, this movement of more than six million African Americans from American's rural southern regions to its urban northern regions occurred over more than 50 years, from 1916 to 1970. Some historians separate this great move into two periods — the first from 1916 to 1940, during which 1.6 million people moved from the rural south to the industrial north, and the second following the Great Depression, from 1940 to 1970, which saw more than 5 million people, many with urban skills, move north and west.
