The New York metropolitan area, also called the Tri-State area and sometimes referred to as Greater New York or Metro New York, is the largest metropolitan economy in the world, with a gross metropolitan product of over US$2.6 trillion. It is also the largest metropolitan area in the world by urban landmass, encompassing 4,669.0 sq mi (12,093 km). Among the most populous metro areas in the world, New York is the largest metropolitan statistical area in the United States and the only one with more than 20 million residents, according to the 2020 U.S. Census.
The core of this vast area, the New York metropolitan statistical area, includes New York City and much of Downstate New York (Long Island as well as the mid- and lower Hudson Valley), northern and central New Jersey (including that state's eleven largest municipalities), and Southwestern Connecticut. The phrase Tri-State area is used to refer to the larger urbanized area of Downstate New York, northern New Jersey, and western Connecticut. The urban region's combined statistical area, the New York–Newark, NY–NJ–CT–PA combined statistical area, spans four states.
