I don't think it's as much of an issue as it would be in Baltimore, since New Haven is also technically a part of the NYC metro region and has lots of other good sized cities around it. I think there are likely about 1,000,000 or more people who work in the general area within a really easy 30-45 minute drive of New Haven (this includes Hartford), and of those, only about 30,000 either work or go to school at Yale or the Yale-New Haven Hospital.I know a lot of people who work in Hartford who live in New Haven for example.
