The island comprises four counties in the U.S. state of New York: Kings and Queens (which comprise the New York City boroughs of Brooklyn and Queens, respectively) to the west; and Nassau and Suffolk to the east . However, many people in the New York metropolitan area (even those living in Brooklyn and Queens) colloquially use the term "Long Island" (or "The Island") exclusively to refer to the Nassau--Suffolk county area collectively, which is mainly suburban in character . The majority of New York City residents now live on Long Island . </P> <P> More generally, "Long Island" may also refer collectively both to the main Island as well as its nearby, surrounding outer barrier islands . North of the island is the Long Island Sound, across which lie the states of Connecticut and a small part of Rhode Island across the Block Island Sound . Across the Sound, to the northwest, lies Westchester County on mainland New York . To the west, Long Island is separated from the Bronx and the island of Manhattan by the East River . To the extreme southwest, it is separated from the New York City borough of Staten Island and the U.S. state of New Jersey by Upper New York Bay, the Narrows, and Lower New York Bay . To the east lie Block Island and numerous smaller islands . </P>
