Where do most of the people working in the theatre in New York live? Do a fair amount of them live in Manhattan for conveniences sake, or do a lot commute from Jersey or something?
People in the theatre profession who live in New York live all over. You'll find them in all five boroughs, further out on Long Island, commuting in from Westchester, Connecticut, New Jersey, even from areas up in the Hudson Valley. There is no one single area that "most" live in.
