Long Island is a densely populated island off the East Coast of the United States, beginning at New York Harbor just 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 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 in Queens and Brooklyn. However, many people in the New York metropolitan area colloquially use the term Long Island to refer exclusively to Nassau and Suffolk Counties, which are mainly suburban in character, conversely employing the term the City to mean Manhattan alone.
