Well I lived in Far Rockaway. All black. My family moved because the neighborhood was getting too rough and robberies were rampant. I actually grew up in Long Beach, NY. A good party, drinking community on the Ocean. The city is very segregated though. I lived in the "west end" which was majority Irish with Italians and Germans. A christian area basically. Going east along the ocean you have the Jewish area- Orthodox, reform and hasid who all hate each other:) On the other side- the bay side you have the hispanic and black community. We didn't go to the "black area" to hang out and they did not come to our part of town to party. Then again we beat up a lot more "out of towners" than any race. Most towns are segregated around these parts is my overall message. Al, look it up on fair data you can probably tell the different neighborhoods by socioecon. 11561.
Yes, Nassau county is one of the most segragated places.
I think San Jose, CA is one of the least.
