New York – often called New York City or the City of New York to distinguish it from the State of New York, of which it is a part – is the most populous city in the United States and the center of the New York metropolitan area, the premier gateway for legal immigration to the United State and one of the most populous urban agglomerations in the world. A global power city, New York exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment. Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.
On one of the world’s largest natural harbors, New York City consists of five boroughs, each of which is a county of New York State. The five boroughs – Brooklyn, Queens, Manhattan, the Bronx, and Staten Island – were consolidated into a single city in 1898. With a census-estimated 2013 population of 8,405,837 distributed over a land area of just 305 square miles (790 km2), New York is the most densely populated major city in the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. By 2013 census estimates, the New York City metropolitan region remains by a significant margin the most populous in the United States, as defined by both the Metropolitan Statistical Area (19.9 million residents) and the Combined Statistical Area (23.5 million residents). In 2013, the MSA produced a gross metropolitan product (GMP) of nearly US$1.39 trillion, while in 2012, the CSA generated a GMP of over US$1.55 trillion, both ranking first nationally by a wide margin and behind the GDP of only twelve nations and eleven nations, respectively.
