Block Island, R.I.

Average household income: $99,380

Located 13 miles south of the coast of Rhode Island, and 14 miles east of New York’s Montauk, the island also known as New Shoreham was called one of “The Last Great Places” by The Nature Conservancy. This tourist-friendly year-round community is accessible only by ferry from Montauk; New London, Conn.; or Newport, R.I.; or by 12-minute flights from Westerly, R.I. It has over 300 fresh-water ponds and more than 17 miles of beaches and is especially popular as a destination during the Race Week regattas and on Independence Day.
