About New Jersey

New Jersey is a state located in both the Mid-Atlantic and Northeastern regions of the United States. Located at the geographic hub of the heavily urbanized Northeast megalopolis, it is bordered to the northwest, north, and northeast by New York State; on its east, southeast, and south by the Atlantic Ocean; on its west by the Delaware River and Pennsylvania; and on its southwest by Delaware Bay and Delaware. At 7,354 square miles (19,050 km2), New Jersey is the fifth-smallest U.S. state by land area. According to a 2025 U.S. Census Bureau estimate, it is the 11th-most populous state, with over 9.5 million residents, its highest estimated count ever. The state capital is Trenton, and the state's most populous city is Newark. New Jersey is the most densely populated U.S. state, and is the only U.S. state in which every county is deemed urban by the U.S. Census Bureau.

New Jersey was first inhabited by Paleo-Indians as early as 13,000 BC. The Lenape were the dominant Indigenous group when Europeans arrived in the early 17th century, and they were subdivided into dialectal groups such as the Munsee, in the north, and the Unami and the Unalachtigo, elsewhere. Dutch and Swedish colonists founded the first European settlements in the state, with the British later seizing control of the region and establishing the Province of New Jersey, named after the Channel Island of Jersey. The colony's fertile lands and relative religious tolerance drew a large and diverse population. New Jersey was among the Thirteen Colonies that supported the American Revolution, hosting several pivotal battles and military commands in the American Revolutionary War earning the title "Crossroads of the American Revolution". New Jersey remained in the Union during the American Civil War and provided troops, resources, and military leaders in support of the Union Army.

New Jersey in Depth

History

The pressure of collision between North America and Africa gave rise to the Appalachian Mountains. Around 18,000 years ago, the Ice Age resulted in glaciers that reached New Jersey. As glaciers retreated, they left behind Lake Passaic along with rivers, meadows, swamps, and gorges.

Since the 6th millennium BC, Native American people have inhabited New Jersey, beginning with the Lenape tribe. Scheyichbi is the Lenape name for the land that represents present-day New Jersey. The Lenape were several autonomous groups that practiced maize agriculture in order to supplement their hunting and gathering in the region surrounding the Delaware River, the lower Hudson River, and western Long Island Sound. The Lenape were divided into matrilineal clans that were based upon common female ancestors.

Geography

New Jersey is at the center of the Northeast megalopolis, the most populated American urban agglomeration. It is bordered to the north and northeast by New York (parts of which are across the Hudson River, Upper New York Bay, the Kill Van Kull, Newark Bay, and the Arthur Kill); to the east by the Atlantic Ocean; to the southwest by Delaware across Delaware Bay; and to the west by Pennsylvania across the Delaware River.

New Jersey is broadly divided into the North, Central, and South Jersey geographic regions, although some residents do not consider Central Jersey a region in its own right. Across the regions are five distinct areas divided by natural geography and population concentration.

Economy

According to the U.S. Bureau of Economic Analysis, in 2025, New Jersey's gross state product was $887.1 billion and the state's per capita personal income was $88,223.

New Jersey's per capita gross state product routinely ranks among the highest in the nation. In 2020, New Jersey had more millionaires both per capita and per square mile, representing roughly 9.76% of all New Jersey household, than any state in the nation.

The state is ranked second in the nation by the number of places with per capita incomes exceeding the national average with 76.4%. Three of New Jersey's counties are among the 20 highest income U.S. counties in the nation as of 2023.

Demographics

Residents of New Jersey are most commonly referred to as New Jerseyans or, less commonly, as New Jerseyites. According to the 2020 U.S. census, the state had a population of 9,288,994, a 5.7% increase since the 2010 U.S. census, which counted 8,791,894 residents. The state ranked eleventh in the country by total population and first in population density, with 1,185 residents per square mile (458 per km2).

Visiting New Jersey

New Jersey is a state in the Mid-Atlantic region of the United States. Located in the crossroads between New York City and Philadelphia, New Jersey is the most densely populated state in the U.S. In spite of its mostly suburban landscape, New Jersey is also known for its vibrant beach towns and natural wonders such as the Pine Barrens, the migratory birds of Cape May, the Delaware Water Gap, a 72 mi (116 km) portion of the Appalachian Trail, and the Palisades. Nicknamed the "Garden State" for its greenery, over a quarter of New Jersey's land is dedicated to agriculture. This can be seen in the blueberry farms and cranberry bogs scattered throughout the southern and western parts of the state.
