New Jersey is a state in the Mid-Atlantic region of the United States. It is bordered on the northeast by 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 largely within the sprawling metropolitan areas of New York City and Philadelphia. It 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 1600s, the Dutch and the Swedes made the first European settlements. The English 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 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. Today, New Jersey has the highest population density and the second highest median income of any state in the United States. Only Maryland has a higher median income. The Governor of New Jersey is Republican Chris Christie.
New Jersey can be thought of as five regions, based on natural geography and population. Northeastern New Jersey, the Gateway Region, lies within the New York metropolitan area, and some residents commute into the city to work. Northwestern New Jersey, or the "Skylands", is, compared to the northeast, more wooded, rural, and mountainous, but still a popular place to live. The "Shore", along the Atlantic Coast in the central-east and southeast, has its own natural, residential, and lifestyle characteristics owing to its location by the ocean. The central-west and southwest are within metropolitan Philadelphia, and are included in the Delaware Valley. The fifth region is the Pine Barrens in the interior of the southern part. Covered rather extensively by mixed pine and oak forest, it has a much lower population density than much of the rest of the state.
New Jersey also can be broadly divided into three geographic regions: North Jersey, Central Jersey, and South Jersey. Some New Jersey residents do not consider Central Jersey a region in its own right, but many believe it is a separate geographic and cultural area from the North and South.
The federal Office of Management and Budget divides New Jersey's counties into seven Metropolitan Statistical Areas, including sixteen counties in the New York City or Philadelphia metro areas. Four counties have independent metro areas, and Warren County joins another Pennsylvania-based metro area.
