Demographics
A Portrait of Oak Bluffs
Oak Bluffs covers about 7.3 square miles of land on the northeast shore of Martha’s Vineyard, wrapped in far more water than land, and its year-round population swells many times over each summer. About one resident in four is 65 or over, while nearly one in four is under 18, so the town holds both an aging core and young families. Roughly seven in ten homes are owner-occupied, households average 2.5 people, and about one resident in ten was born outside the United States. Figures below are from the U.S. Census Bureau and the Secretary of the Commonwealth. Follow the source links for the latest.
