New York County is coterminous with the Borough of Manhattan, and is part of the City of New York, along with Kings County (Brooklyn), Queens County (Queens), Bronx County (The Bronx), and Richmond County (Staten Island). The figure shown here is for New York County/Manhattan, and does not include the other four boroughs' GDP.

Denver, Philadelphia, and San Francisco are consolidated city-counties.
