To identify America’s most segregated cities, 24/7 Wall St. calculated the percentage of a metropolitan area’s black residents who live in majority black census tracts — statistical subdivisions with an average of about 4,000 people. The greater the share of black metro residents living in the area’s racially homogenous neighborhoods, the greater the degree of segregation. We only considered census tracts with at least 500 residents. Population data are based on five-year estimates through 2017 from the U.S. Census Bureau’s American Community Survey. For the purpose of this story, we only considered segregation of white and black populations.
We also reviewed median household income, poverty rates, educational attainment rates, unemployment rates, and homeownership rates among black and white populations in each metro area from the ACS. All data are five-year estimates.
