Manhattan is an island and a borough of New York City. Its boundaries are coterminous with New York County. The island is limited by Hudson River in the west and East River in the east. It has a population of 1,537,195 and an area of 59.47 km² (22.96 miles²).
Downtown is the southernmost part of Manhattan. It is the oldest part of the city, and was settled by Dutch colonists. Unlike the rest of the Island, Downtown does not have its streets arranged in a grid pattern.
The area between 14th Street and 59th Street is known as Midtown. Midtown is the most important commercial district of the United States, and most of New York City's skyscrapers lie here.
Midtown Manhattan includes neighborhoods like Hell's Kitchen, the Theater District, Chelsea, and Madison Square. Central Park is located in the Midtown, as well as sights like Rockefeller Center, the Empire State Building, Madison Square Garden, the Chrysler Building, and Times Square.
Uptown Manhattan includes neighborhoods such as the Upper West Side, Upper East Side, Harlem, Morningside Heights, and Spanish Harlem. Sometimes the term "Upper Manhattan" is used when describing the parts of Manhattan north of 96th Street, when one wants to exclude the affluent areas Upper West Side and Upper East Side from the poorer neighborhood further north.
