Checking some of the zips, the highest seems to be the old Hell’s Kitchen neighborhood, Jamaica and Rosedale in Queens, just over the border in Harlem. Also Greenwich village. So not only the blacks, but also the “artists”.
Well, Jamaica and Rosedale are black but Greenwich Village and the stupidly renamed Hell’s Kitchen? (Clinton, yuck!) Mostly young single women, I would guess, although there are plenty of Section 8s and welfare recipients who are all over Manhattan. And maybe some prostitutes. My neighborhood in Curry Hill is loaded with Methadone addicts and welfare recipients living in the horrible old tenements.
