New York City is comprised of five boroughs: Manhattan, Brooklyn, Queens, Staten Island, and The Bronx. Manhattan is the smallest and most densely populated borough of New York City. Below is a map delineating the neighborhoods that comprise Manhattan, created by designer Alexander Cheek.
Located primarily on the island of Manhattan at the mouth of the Hudson River, the borough is conterminous with New York County, an original county of the state of New York. New York County is the most densely populated county in the United States, and one of the most densely populated areas in the world, with a 2010 population of 1,585,873 living in a land area of 22.96 square miles, or 69,464 residents per square mile, more dense than any individual American city. It is also one of the wealthiest counties in the United States, with a 2005 per capita income above $100,000. Manhattan is the third-largest of New York's five boroughs in population, and its smallest borough in land area.
