What are the wealthiest towns?

Long Island is home to many of New York’s wealthiest communities, particularly along the Gold Coast, the North Shore, and the Hamptons. These areas are known for luxury real estate, waterfront estates, historic mansions, highly rated school districts, and some of the highest household incomes and home values in the region.

In Short

Communities including Old Westbury, Brookville, Sands Point, Manhasset, Lloyd Harbor, East Hampton, Southampton, and Sagaponack consistently rank among Long Island’s most affluent places to live. Wealth can be measured in several ways, including household income, home values, and concentrations of high-net-worth residents.

What Are the Wealthiest Communities on Long Island?

There is no single official ranking of Long Island’s wealthiest communities because affluence can be measured by median household income, real estate values, overall wealth, or other economic indicators. Regardless of the method used, a relatively small group of communities consistently ranks among the island’s most prestigious residential areas.

Many of Nassau County’s wealthiest communities are located along the historic Gold Coast, where industrialists and business leaders built grand estates during the late nineteenth and early twentieth centuries. Today, communities such as Old Westbury, Brookville, Sands Point, and Manhasset continue to attract affluent homeowners seeking spacious properties, excellent schools, and convenient access to New York City.

In Suffolk County, affluent communities extend along the North Shore and throughout the Hamptons. Lloyd Harbor is known for its wooded waterfront estates overlooking Long Island Sound, while East Hampton, Southampton, and Sagaponack are internationally recognized for luxury homes, oceanfront estates, and some of the country’s most valuable residential real estate.

Although these communities share a reputation for affluence, they differ considerably in character. Some feature historic Gold Coast mansions on large wooded estates, while others are known for beachfront properties, equestrian estates, golf communities, or vibrant downtown shopping districts.

Long Island’s wealthiest communities are found across both Nassau and Suffolk counties, from the historic estates of the Gold Coast to the oceanfront villages of the Hamptons. Whether measured by household income, luxury home values, or long-standing prestige, these communities continue to rank among the most desirable places to live in New York. For homebuyers, visitors, and those interested in Long Island’s history and architecture, they represent some of the island’s most distinctive and recognizable destinations.
