Actually, PIttsburgh is one of the MOST segregated Cities/(Towns) in the Northeast/Midwest....

Bloomfield = mostly white, HUGE italian community
Polish Hill = Need I say more?
Greenfield = mostly white, slavic community
Homewood/Brushton = mostly black
Lincoln/Lemminton = mostly black
East Hills = mostly black
Shadyside = mostly white, mostly rich, with losts of "artsy-fartsy types and gays
Oakland = mostly consumed by the University of Pittsburgh and Carnegie Mellon, so it doesn't count...
