Long Island is an island located in the southeast part of the U.S. state of New York, just east of Manhattan. Stretching northeast into the Atlantic Ocean, Long Island contains four counties, two of which are boroughs of New York City (Queens and Brooklyn), and two of which are mainly suburban (Nassau and Suffolk). The term "Long Island" often refers only to Nassau and Suffolk counties in order to differentiate them from New York City, though all four counties on the island are part of the New York metropolitan area.
As of the 2010 census, Long Island had a population of 7,568,304, making it the most populated island in any U.S. state or territory. It is also the 17th most populous island in the world, ahead of Ireland, Jamaica and the Japanese island of Hokkaidō. Its population density is Template:Convert. If it were a state, Long Island would rank 13th in population (after Virginia) and first in population density.
