New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is located on a peninsula, bordered on the north and east by the state of New York along the extent of the length of New York City on its western edge. New Jersey is the fourth-smallest state by area but the 11th-most populous, with 9 million residents as of 2017, the most densely populated of the 50 U. S. states. New Jersey lies within the combined statistical areas of New York City and Philadelphia. New Jersey was the second-wealthiest U. S. state by median household income as of 2017. New Jersey 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 founded the first European settlements in the state; the English seized control of the region, naming it the Province of New Jersey after the largest of the Channel Islands and granting it as a colony to Sir George Carteret and John Berkeley, 1st Baron Berkeley of Stratton.
New Jersey was the site of several decisive battles during the American Revolutionary War in the 18th century. In the 19th century, factories in cities, Paterson, Trenton, Jersey City, Elizabeth helped to drive the Industrial Revolution. New Jersey's geographic location at the center of the Northeast megalopolis, between Boston and New York City to the northeast, Philadelphia and Washington, D. C. to the southwest, fueled its rapid growth through the process of suburbanization in the second half of the 20th century. In the first decades of the 21st century, this suburbanization began reverting with the consolidation of New Jersey's culturally diverse populace toward more urban settings within the state, with towns home to commuter rail stations outpacing the population growth of more automobile-oriented suburbs since 2008. Around 180 million years ago, during the Jurassic Period, New Jersey bordered North Africa; the pressure of the collision between North America and Africa gave rise to the Appalachian Mountains.
Around 18,000 years ago, the Ice Age resulted in glaciers. As the glaciers retreated, they left behind Lake Passaic, as well as many rivers and gorges. New Jersey was settled by Native Americans, with the Lenni-Lenape being dominant at the time of contact. Scheyichbi is the Lenape name for the land, now 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, western Long Island Sound. The Lenape society was divided into matrilinear clans; these clans were organized into three distinct phratries identified by their animal sign: Turtle and Wolf. They first encountered the Dutch in the early 17th century, their primary relationship with the Europeans was through fur trade; the Dutch became the first Europeans to lay claim to lands in New Jersey. The Dutch colony of New Netherland consisted of parts of modern Middle Atlantic states. Although the European principle of land ownership was not recognized by the Lenape, Dutch West India Company policy required its colonists to purchase the land that they settled.
The first to do so was Michiel Pauw who established a patronship called Pavonia in 1630 along the North River which became the Bergen. Peter Minuit's purchase of lands along the Delaware River established the colony of New Sweden; the entire region became a territory of England on June 24, 1664, after an English fleet under the command of Colonel Richard Nicolls sailed into what is now New York Harbor and took control of Fort Amsterdam, annexing the entire province. During the English Civil War, the Channel Island of Jersey remained loyal to the British Crown and gave sanctuary to the King, it was from the Royal Square in Saint Helier that Charles II of England was proclaimed King in 1649, following the execution of his father, Charles I. The North American lands were divided by Charles II, who gave his brother, the Duke of York, the region between New England and Maryland as a proprietary colony. James granted the land between the Hudson River and the Delaware River to two friends who had remained loyal through the English Civil War: Sir George Carteret and Lord Berkeley of Stratton.
The area was named the Province of New Jersey. Since the state's inception, New Jersey has been characterized by religious diversity. New England Congregationalists settled alongside Scots Presbyterians and Dutch Reformed migrants. While the majority of residents lived in towns with individual landholdings of 100 acres, a few rich proprietors owned vast estates. English Quakers and Anglicans owned large landholdings. Unlike Plymouth Colony and other colonies, New Jersey was populated by a secondary wave of immigrants who came from other colonies instead of those who migrated directly from Europe. New Jersey remained agrarian and rural throughout the colonial era, commercial farming developed sporadically; some townships, such as Burlington on the Delaware River and Perth Amboy, emerged as important ports for shipping to New York City and Philadelphia. The colony's fertile lands and tolerant religious policy drew more settlers, New Jersey's population had increased to 120,000 by 1775. Settlement for the first 10 years of English rule took place along Hackensack River and Arthur Kill –

In the late 1920s the Trenton Board of Education had the foresight and the good fortune to acquire one of the last undeveloped tracts in the city: the 36-acre Chambers Farm used as a nursery. The new high school would be the city's third, replacing the existing high school at Chestnut and Hamilton Avenues built in 1900, which in turn replaced the first high school on Mercer Street built in 1874. Trenton Central High School opened on January 4, 1932, was dedicated on January 18 at ceremonies attended by 5,000 people. Hailed as "an ornament to the city" and "one of the show places of Trenton," TCHS was one of the largest and most expensive high schools built in the country; the Chambers Street façade stretches broadly for 1,000 feet, nearly as long as the Empire State Building is tall. The cost of the building, including land and furniture, totaled $3.3 million. Most firms involved in the construction were based in Trenton, including John A. Roebling's Sons who provided "Jersey" wire lath to fireproof the ceilings and walls.
Trenton Central High School is divided into Small Learning Communities that span across three separate sites throughout the city of Trenton. The Chambers Campus, located on Chambers Street, houses five communities: Applied Science and Engineering, Media Technology, Performing Arts, Hotel and Tourism, Business, Technology Design; the North Campus is home to the Medical Arts community.

Central Jersey is the central region of the U. S. state of New Jersey. The designation of central New Jersey with a distinct toponym is a colloquial one rather than an administrative one, with no official definition and a contentious taxonomic existence. There are varying descriptions as to. North Jersey and South Jersey have been used to describe the northern and southern halves of New Jersey, in the United States. While there is agreement that their border is somewhere in the middle third of the state, there is no official delineation; the region lies at the geographic heart of the Northeast Megalopolis. All descriptions of Central Jersey include Middlesex County, the center of population of New Jersey, tend to include the region radiating from New Brunswick in Middlesex County and comprising much of Monmouth and Somerset counties; the inclusion of adjacent areas of Hunterdon and Ocean counties is subjective and a source of debate. The intersection of the two busiest highways in New Jersey, namely the New Jersey Turnpike and the Garden State Parkway, is located in Woodbridge, Middlesex County.
Trenton, the seat of Mercer County, is the state capital of New Jersey. New Jersey's geographic center is located in Mercer County. In 2011, the population center of the state was alongside Nenninger Lane in the western portion of East Brunswick Township, known as the "Heart of Middlesex County". There are other related, overlapping areas. While the region is considered part of the larger New York metropolitan area in its greatest extent, Mercer County constitutes a separate Metropolitan Statistical Area; the Metropolitan Statistical Areas of New Jersey further subdivides the middle third of the state into smaller groups of counties. Many people residing closer to the northern and southern edges of New Jersey do not recognize Central Jersey and distinguish North and South Jersey; the Delaware Valley is another area. Mercer County is included in the Philadelphia-Reading-Camden Combined Statistical Area, as defined by the United States Census Bureau; some parts of Hunterdon County associate themselves with the Delaware Valley and the Philadelphia Area, although Hunterdon County isn't geographically defined in this area.
The New Jersey Department of Tourism places Middlesex and Union in the Gateway Region and Mercer in the Delaware Valley. Monmouth and Ocean counties are considered part of the Jersey Shore, while Somerset and Hunterdon counties are part of Skylands Region; the Raritan Valley is the region along the middle reaches of the Raritan River and its North Branch and South Branch. The Raritan Valley includes the communities of Branchburg, Somerville, Hillsborough, Green Brook, North Plainfield, Bound Brook, South Bound Brook, all in Somerset County; the Raritan Bayshore is used to describe the region in Monmouth County along the coastline of the Raritan Bay from South Amboy to Sandy Hook. Kingston is the only tri-county community in New Jersey; the telephone area codes 732 and 848 includes Middlesex and Union, northern Ocean counties. At least two counties in Central Jersey carry official nicknames: Mercer County is known as "The Capital County" and Middlesex County carries the nickname, "The Greatest County in the Land".
Between 1674 and 1702, in the early part of New Jersey's colonial period, the border between West Jersey and East Jersey ran diagonally across the middle part of the state. The Keith Line, as the demarcation is known, ran through the center of; this border remained important in determining ownership and political boundaries until 1745. Remnants of that division are seen today, notably as the Hunterdon-Somerset, Ocean-Burlington, Monmouth-Burlington county lines; the division of the two provinces was cultural as well as geographical. New Jersey's position between the major cities of New York and Philadelphia led Benjamin Franklin to call the state "a barrel tapped at both ends". Travel between the two cities included a ferry crossing. Due to the obstacles created by the Meadowlands and the Hudson Palisades, passengers from New York would cross the North River and the Upper New York Bay by boat and transfer to stagecoaches to travel overland through what is now Central Jersey. One route from Elizabethtown to Lambertville was known as Old York Road.
Another route, from Perth Amboy through Kingston to Burlington, ran along a portion of the Kings Highway, These roads followed Lenape paths known as the Naritcong Trail and the Assunpink Trail. Raritan Landing, across from New Brunswick in today's Piscataway, became was important inland port and commercial hub for the region. Two of the nine Colonial Colleges, founded before the American Revolution, were the College of New Jersey, Queens College. All of the region's counties are ranked among the highest income counties in the United States, as measured by median household income, it has been called the state's "wealth belt". For decades, Central Jersey was a hub for manufacturing in the eastern United States. Many industrial companies had major production facilities in and around the area, including Edison Assembly, Ford Motor Company's production plant for Rangers, Pintos and Lincolns. Other notable companies include General Motors in Linden, Frigidaire's air-conditioner plant in Edison, Hess Corporation in Woodbridge, Sie

Mercer County, New Jersey
Mercer County is a county located in the U. S. state of New Jersey. Its county seat is the state capital; the county constitutes the Trenton-Ewing, NJ Metropolitan Statistical Area and is considered part of the New York Metropolitan Area by the United States Census Bureau, but directly borders the Philadelphia metropolitan area and is included within the Federal Communications Commission's Philadelphia Designated Market Area and the greater Philadelphia-Reading-Camden Combined Statistical Area. As of the 2017 Census estimate, the county's population was 374,733, making it the state's 12th-most populous county, an increase of 2.2% from the 2010 United States Census, when its population was enumerated at 366,513, in turn an increase of 15,752 from the 350,761 enumerated in the 2000 Census, retaining its position as the 12th-most populous county in the state. In 2015, the county had a per capita personal income of $63,247, the sixth-highest in New Jersey and ranked 121st of 3,113 counties in the United States.
Mercer County stands among the highest-income counties in the United States, with the Bureau of Economic Analysis having ranked the county as having the 78th-highest per capita income of all 3,113 counties in the United States as of 2009. The county was formed by an act of the New Jersey Legislature on February 22, 1838, from portions of Burlington County, Hunterdon County, Middlesex County; the former Keith Line bisects the county and is the boundary between municipalities, separated into West Jersey and East Jersey. It was named for Continental Army General Hugh Mercer, who died as a result of wounds received at the Battle of Princeton on January 3, 1777; the Mercer Oak, against which the dying general rested as his men continued to fight, appears on the county seal and stood for 250 years until it collapsed in 2000. Mercer County is home to Princeton University, Princeton Theological Seminary, the Institute for Advanced Study, Rider University, The College of New Jersey, Thomas Edison State University and Mercer County Community College.
Trenton-Mercer Airport, in Ewing Township, is a commercial and corporate aviation airport serving Mercer County and its surrounding vicinity.

National Register of Historic Places and the New Jersey Register of Historic Places. Founded February 22, 1838, from portions of surrounding counties, Mercer County has a historical impact that reaches back to the pivotal battles of the American Revolutionary War. On the night of December 25–26, 1776, General George Washington led American forces across the Delaware River to attack the Hessian barracks in Trenton on the morning of December 26 known as the First Battle of Trenton. Following the battle, Washington crossed back to Pennsylvania, he crossed a third time in a surprise attack on the forces of General Charles Cornwallis at the Battle of the Assunpink Creek, on January 2, 1777 known as the Second Battle of Trenton, at the Battle of Princeton on January 3.
The successful attacks built morale among the pro-independence colonists. Mercer County has the distinction of being the famed landing spot for a fictional Martian invasion of the United States. In 1938, in what has become one of the most famous American radio plays of all time, Orson Welles acted out his The War of the Worlds invasion, his imaginary aliens first "landed" at what is now West Windsor Township. A commemorative monument is erected at Grover's Mill park. There were 27 Mercer County residents killed during the September 11, 2001 terrorist attacks in Lower Manhattan. A 10-foot long steel beam weighing one ton was given to the county by the Port Authority of New York and New Jersey in March 2011 and is now displayed at Mercer County Park. According to the 2010 Census, Mercer County had a total area of 228.89 square miles, including 224.56 square miles of land and 4.33 square miles of water. The county is flat and low-lying on the inner coastal plain with a few hills closer to the Delaware River.
