New York City At Night, New York, United States

- Manhattan (New York County; 2009 Est. Pop.: 1,629,054) is the most densely populated borough and is home to Central Park and most of the city's skyscrapers. The borough is the financial center of the city and contains the headquarters of many major corporations, the United Nations, a number of important universities, and many cultural attractions. Manhattan is loosely divided into Lower, Midtown, and Uptown regions. Uptown Manhattan is divided by Central Park into the Upper East Side and the Upper West Side, and above the park is Harlem.
- The Bronx (Bronx County: Pop. 1,397,287) is New York City's northernmost borough, the location of Yankee Stadium, home of the New York Yankees, and home to the largest cooperatively owned housing complex in the United States, Co-op City. Except for a small section of Manhattan known as Marble Hill, the Bronx is the only section of the city that is part of the United States mainland. It is home to the Bronx Zoo, the largest metropolitan zoo in the United States, which spans 265 acres (1.07 km2) and is home to over 6,000 animals. The Bronx is the birthplace of rap and hip hop culture.
- Brooklyn (Kings County: Pop. 2,567,098), on the western tip of Long Island, is the city's most populous borough and was an independent city until 1898. Brooklyn is known for its cultural, social and ethnic diversity, an independent art scene, distinct neighborhoods and a distinctive architectural heritage. It is also the only borough outside of Manhattan with a distinct downtown neighborhood. The borough features a long beachfront and Coney Island, established in the 1870s as one of the earliest amusement grounds in the country.
- Queens (Queens County: Pop. 2,306,712) is geographically the largest borough and the most ethnically diverse county in the United States, and may overtake Brooklyn as the city's most populous borough due to its growth. Historically a collection of small towns and villages founded by the Dutch, today the borough is predominantly residential and middle class. Queens County is the only large county in the United States where the median income among African Americans, approximately $52,000 a year, is higher than that of White Americans. Queens is the site of Citi Field, the home of the New York Mets, and annually hosts the U.S. Open tennis tournament. Additionally, it is home to two of the three major airports serving the New York metropolitan area, LaGuardia Airport and John F. Kennedy International Airport. (The third is Newark Liberty International Airport in Newark, New Jersey.)
