Philly named No. 9 most segregated urban area in the U.S.

According to a slideshow article on that analyzed 2010 Census data, the level of segregation between blacks and whites in Philadelphia  is declining at slower rate than it did in the 1990s.

University of Pennsylvania historian Thomas Sugrue credits Philly’s No. 9 status partially due to hegemony.

“The patterns of housing segregation in metropolitan Philadelphia are the legacy of discriminatory public policies and real-estate practices that played out for most of the 20th century,” Sugrue said in the article. “Though discrimination is now illegal, those patterns of segregation were so deeply entrenched that many people came to see them as ‘natural.'”
