Northeast Philly is very blue collar white. The jewish segment which dominated until the 70's moved away with their wealth. Many of the blue collar jewish stayed. The police and detectives in Northeast Philly keep things tight. A lot of ethnic Russians and like have also back-filled the void of those who have left. Once you cross the line into Bucks County, like Croyden, Neshaminy, you hit pretty much the same thing. There are very few cultural divides in that direction.
Now if you head south of Erie Street, you are in peril no matter what color you are.
