The Gateway Region is the primary urbanized area of the northeastern section of New Jersey. It is anchored by Newark, the state's most populous city. It is part of the New York metropolitan area.
The area encompasses Bergen, Essex, Hudson, Passaic, Union and Middlesex counties. It is the most urban part of the state, with a population of more than four million, and is home to most of its larger cities, though much housing was originally developed as suburbs of neighbouring New York City.[1][2][3][4] It is home to Ellis Island, the "gateway" through which many immigrants entered the United States, many of whom chose to stay in the region, which continues to be the port of entry and first home to many born abroad, making it one of the most ethnically diverse of the nation. It may also be the most socio-economically diverse, with some of the biggest pockets of poverty and most exclusive of suburbs in the state.[5]
The designation Gateway Region has not caught on in local parlance, as the topography and self-identification of the residents tend not to correspond to the collective name. The terms North Jersey and Central Jersey are used in describing parts of the Gateway. The name may have been taken from the 1960s Newark nickname Gateway City after the newly developed Gateway Center downtown. Amtrak's high-speed rail project throughout the region is called Gateway. It is one of seven tourism regions established by the New Jersey State Department of Tourism, the others being the Greater Atlantic City Region, the Southern Shore Region, the Delaware River Region, the Shore Region, Central Jersey Region, and the Skylands Region.[6] The Gateway National Recreation Area, though not located inside the Gateway Region, is nearby.
