 It is estimated that less than 1% of Los Angeles's 461,000 black residents lived in communities without a black majority in 1960, resulting in de facto segregation.In order to exploit the poor financial situation many migrants were in, areas of low income housing were established in places city planners wanted them to live.For example, the South Side area of Chicago and the South Central region of Los Angeles were established as designated areas for African Americans as early as the 1920s and 1930s respectively.
