Depression in 1929, its African-American population had climbed to 120,000. In 1900-1901, Chicago had a total population of 1,698,575. By 1920, the city had added more than 1 million residents. During the second wave of the Great Migration (1940–1960), the African-American population in the city grew from 278,000 to 813,000. The flow of African Americans to Ohio, particularly to Cleveland, changed the demographics of the state and the primary industrial city. Before the Great Migration, an estimated 1.1% to 1.6% of Cleveland’s population was African American.[8] By 1920, 4.3% of Cleveland’s population was African American. The number of African Americans in Cleveland continued to rise over the next 20 years of the Great Migration.
