Brooklyn

Brooklyn is a borough of New York City coterminous with Kings County, the most populous county in the U.S. state of New York and the second-most densely populated county in the United States. It is New York City's most populous borough, with an estimated 2,504,700 residents in 2010. Named after the Dutch village of Breukelen, it borders the borough of Queens at the western end of Long Island. Brooklyn has several bridge and tunnel connections to the borough of Manhattan across the East River, and the Verrazzano-Narrows Bridge connects it with Staten Island.

With a land area of 70.82 square miles and water area of 26 square miles, Kings County is New York state's fourth-smallest county by land area and third-smallest by total area, though it is the second-largest among the city's five boroughs. Today, if each borough were ranked as a city, Brooklyn would rank as the third-most populous in the U.S., after Los Angeles and Chicago.
