New Jersey is a state in the Northeastern and Middle Atlantic regions of the United States. As of the United States 2010 Census[update], its population was 8,791,894. It is bordered on the north and east by the state of New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania and on the southwest by Delaware. New Jersey lies mostly within the sprawling metropolitan areas of New York City and Philadelphia and is the most densely populated state in the United States.The area was inhabited by Native Americans for more than 2,800 years, with historical tribes such as the Lenape along the coast.
In the early 17th century, the Dutch and the Swedes made the first European settlements. The British later seized control of the region, naming it the Province of New Jersey. It was granted as a colony to Sir George Carteret and John Berkeley, 1st Baron Berkeley of Stratton. At this time, it was named after the largest of the British Channel Islands, Jersey, where Carteret had been born. New Jersey was the site of several decisive battles during the American Revolutionary War. In the 19th century, factories in cities such as Elizabeth, Paterson, and Trenton helped to drive the Industrial Revolution. New Jersey's position at the center of the Northeast megalopolis, between Boston, New York City, Philadelphia, Baltimore, and Washington, D.C., fueled its rapid growth through the suburban boom of the 1950s and beyond.
