Hudson County, New Jersey in the context of "Population Estimates Program"

In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area (metropolitan statistical area). This term was retired by the US census bureau and replaced by the term principal city, which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau.

Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs. A central city is usually the first settlement established in an urban region, years before the outlying districts came into existence. These cities typically contain less economic activity and more crime than their surrounding areas. Central cities often form the regional downtowns of metro areas. The term is used mainly in US context, although since the 1970s it has also become relatively common in Canada and, to a lesser extent, Europe and Australia.

New York Harbor is a bay that covers all of the Upper Bay. It is at the mouth of the Hudson River near the East River tidal estuary on the East Coast of the United States.

New York Harbor is generally synonymous with Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey, municipalities of Jersey City and Bayonne, although in colloquial usage it can sometimes expand to cover Upper and Lower New York Bay. New York Harbor is one of the largest natural harbors in the world.

Monmouth County (/ˈmɒnməθ/) is a county located in the central portion of the U.S. state of New Jersey. It is bordered to its west by Mercer and Middlesex Counties, to its south by Ocean County, to its east by the Atlantic Ocean, and to its north by the Raritan Bay (sharing a border with the boroughs of Staten Island, Brooklyn, and Queens in New York City, across it). Monmouth County's geographic area comprises 30% water. The county is part of the Jersey Shore region of the state.

As of the 2020 United States census, the county was the state's fifth-most-populous county with a population of 643,615, its highest decennial count ever and an increase of 13,235 (+2.1%) from the 2010 census count of 630,380, which in turn reflected an increase of 15,079 from 615,301 at the 2000 census.

The Gateway Region is the primary urbanized area of the northeastern section of the U.S. state of New Jersey. The region is anchored by Newark, the state's most populous city, and constitutes 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 neighboring New York City. 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.
