The term sixth borough is used to describe any of a number of places that are not politically within the borders of any of the five boroughs of New York City but have been referred to as a metaphorical part of the city by virtue of their geographic location, demographic composition, special affiliation with New York City, or cosmopolitan character. They include adjacent cities and counties in the New York metropolitan area as well as in other states, U.S. territories, and foreign countries.[1][2][3]
