Manhattan

Manhattan, an island at the mouth of the Hudson River, is the most densely populated and the oldest of the five boroughs of New York City. With a population of 1.58 million, there are 26,924 residents per sq km, denser than any individual American city. Manhattan is the third largest of New York's five boroughs in population, but the smallest borough in land area. Manhattan is the major commercial, financial, and cultural centre of the United States. Anchored by Wall Street in Lower Manhattan, New York City functions as the financial capital of the world, with an estimated GDP of over 1.2 trillion and is home of both the New York Stock Exchange and NASDAQ. Many major radio, television and telecommunication companies in the United States are based here, as well as many news, magazine, book and other media publishers. It is also the location of the United Nations Headquarters.
