Martha's Vineyard, MA, United States

With a year-round population of 20,530, Martha's Vineyard swells to over 200,000 in the summer, transforming this island haven into a crowded tourist mecca. The cost of living is 60% higher than the state average, while the working class earns 30% less. Bureaucracy is a persistent headache, as the island's six towns each have their own governance, leading to a push for greater regionalization. While the climate is moderated by the Atlantic Ocean, harsh winters with sub-zero temperatures still occur. Martha's Vineyard is best suited for affluent summer vacationers seeking an exclusive, low-key escape from the mainland.
