Long Island (locally: ) is a densely populated island in Southeast New York in the Northeast part of the United States, beginning at New York Harbor approximately 0.35 miles (0.56 km) from Manhattan Island and extending eastward into the Atlantic Ocean. The island comprises four counties in the U.S. state of New York. Kings and Queens Counties (the New York Cityboroughs of Brooklyn and Queens, respectively) and Nassau County share the western third of the island, while Suffolk County occupies the eastern two-thirds. More than half of New York City's residents now live on Long Island, in Brooklyn, and in Queens. However, many people in the New York metropolitan area (even in Brooklyn and Queens) colloquially use the term Long Island (or the Island) to refer exclusively to Nassau and Suffolk Counties, and conversely, employ the term the City to mean Manhattan alone.
