Migrant Voices: Oral History Interviews on the Great Migration to Pittsburgh External
"This website is dedicated to illuminating Pittsburgh’s place in the Great Migration through the perspectives of Black migrants. Drawn by the promise of good jobs and greater freedom, from 1915 to 1930 over a million African Americans moved from rural communities in the South to urban industrial centers in the North, including Pittsburgh. This opening phase of the Great Migration saw the Steel City’s Black community increase from about 25,000 to 55,000, making it the fifth largest in the nation." [From website.]
