Boston's one of the most expensive cities in the country to live in/near, so that's probably a contributor. I'll point out that small states mean that when you "consider moving" to the suburbs/exurbs, many people are going to be at least "considering" New Hampshire or Rhode Island (possibly even Maine) among their choices if they want to move from the inner Boston metro area to the outer parts of it. Which means answering "yes" to this question regarding you're "considering" moving out of state. Most of the smaller metro areas in the state are similarly on or near state lines as well, like Springfield and Lowell. Even Worcester is commutable from CT.
