The largest concentrations of native-born Black people are in Germantown, North Philadelphia East of Germantown Avenue, the Point Breeze neighborhood of South Philadelphia, parts of Southwest Philadelphia, and West Philadelphia. Together these neighborhoods have a population of about 610,000 and are roughly 82% black; making it the 4th largest predominantly Black area in the United States after Bedford-Stuyvesant, Brooklyn, Detroit, and South Side Chicago. Philadelphia has one of the largest ethnic Black American / native Black populations in the country, tracing their ancestry to descendants of African slaves from the US south.
