Manhattan is the most densely populated and geographically smallest of the five boroughs of New York City. Coextensive with New York County, Manhattan is the smallest county by area in the U.S. state of New York, and one of the smallest in the United States. Located almost entirely on Manhattan Island near the southern tip of the state, Manhattan is centrally located in the Northeast megalopolis and represents the urban core of the New York metropolitan area. Manhattan serves as New York City's economic and administrative center and has been described as the cultural, financial, media, and entertainment capital of the world.
