Next year will mark the 50-year anniversary of the Civil Rights Act of 1968, also known as the Fair Housing Act. The landmark bill prohibited by law long-standing practices of housing segregation based on race by landlords and local governments. Despite the law, housing discrimination never fully disappeared, and the effects of decades of discrimination are evident in U.S. cities — many of which still highly segregated.

The forced segregation of black Americans in neighborhoods with suboptimal schooling, poor public transportation, and fewer job opportunities has led to worse social and economic outcomes for residents in those neighborhoods.

To identify America’s 16 most segregated cities, 24/7 Wall St. calculated the percentage of metropolitan area black residents who live in predominantly black census tracts. While certain racially homogeneous neighborhoods exist in every large metropolitan area, some cities are far more starkly divided. In several U.S. metropolitan areas, more than one-fourth of the African American population lives in neighborhoods that are at least 80% black. In two metro areas, more than half of black residents live in a predominately African American neighborhoods.
