Mercer County is a county located in the U.S. state of New Jersey. Its county seat is Trenton, 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 also directly borders the Philadelphia metropolitan area and is included within the Federal Communications Commission's Philadelphia Designated Market Area. As of 2015, Mercer County's Census-estimated population was 371,398, an increase of 1.3% from the 2010 United States Census, when its population was enumerated at 366,513, in turn an increase of 15,752 (4.5%) from the 350,761 enumerated in the 2000 Census, retaining its position as the 12th-most populous county in the state. 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 (and the sixth-highest in New Jersey) as of 2009.
The county was formed by an act of the New Jersey Legislature on February 22, 1838, from portions of Burlington County (including Nottingham Township), Hunterdon County (including Ewing Township, Lawrence Township, Trenton City and portions of Hopewell Township), and Middlesex County (including West Windsor Township and portions of East Windsor Township). The old Keith Line bisects the county and is the boundary between municipalities that previously had been 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 College and Mercer County Community College.
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. 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 Second Battle of Trenton on January 2, 1777, and 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 (3.0 m) 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, the county had a total area of 228.89 square miles (592.8 km2), including 224.56 square miles (581.6 km2) of land (98.1%) and 4.33 square miles (11.2 km2) of water (1.9%).
The county is generally flat and low-lying on the inner coastal plain with a few hills closer to the Delaware River. Baldpate Mountain, near Pennington, is the highest hill, at 480 feet (150 m) above sea level. The lowest point is at sea level along the Delaware.

Law and government
Mercer County has a county executive form of government, in which the County Executive performs executive functions, administering the operation of the county, and a Board of Chosen Freeholders acts in a legislative capacity. The seven-member Board of Chosen Freeholders is elected at-large to serve three-year staggered terms of office on a staggered basis, with either two or three seats up for election each year. The Board is led by a Freeholder Chair and Vice-Chair, selected from among its members at an annual reorganization meeting held in January. The Freeholder Board establishes policy and provides a check on the powers of the County Executive. The Board approves all county contracts and gives advice and consent to the County Executive's appointments of department heads, and appointments to boards and commissions. The Freeholder Board votes to approve the budget prepared by the Executive after review and modifications are made.
As of 2016[update], the County Executive is Democrat Brian M. Hughes, who was re-elected to a fourth four-year term in November 2015 and is serving a term of office ending December 31, 2019. Mercer County's Freeholders are:

Roads and highways
Mercer County has county routes, state routes, U.S. Routes and Interstates that all pass through. As of 2010[update], the county had a total of 1,524.30 miles (2,453.12 km) of roadways, of which 1,216.48 miles (1,957.73 km) were maintained by the local municipality, 175.80 miles (282.92 km) by Mercer County, 118.99 miles (191.50 km) by the New Jersey Department of Transportation and 13.03 miles (20.97 km) by the New Jersey Turnpike Authority.
The county roads that traverse through are County Route 518 (only in the Hopewells), County Route 524, County Route 526, County Route 533, County Route 535, County Route 539, County Route 546, County Route 569, County Route 571 and County Route 583.
The state routes that pass through Mercer are Route 27 (only in Princeton), Route 29, Route 31, Route 33, Route 129, and Route 133. There are three US Routes that pass through Mercer County, which are: U.S. Route 1 (which bisects the county), U.S. Route 130 and U.S. Route 206.
Mercer County houses a few limited access roads, such as Interstate 295, Interstate 195, and Interstate 95 (which is also designated along the New Jersey Turnpike). (Mercer is the only county in the state that hosts I-95 and both its auxiliary routes.) Two turnpike interchanges are located in Mercer: Exit 7A in Robbinsville and Exit 8 in East Windsor.
Interstate 95 abruptly ends at the interchange with US 1 and I-295 in Lawrence Township, and becomes I-295 south. Signs direct motorists to the continuation of I-95 by using I-295 to I-195 east to Interstate 95 / New Jersey Turnpike. This is all due in part to the cancellation of the Somerset Freeway that was supposed to go from Hopewell in Mercer County up to Franklin in Somerset County.
The 95 shields on the "Trenton section" are to re-numbered as part of I-295 when a direct interchange with Interstate 95 in Pennsylvania and Interstate 276 is built (which will not be until 2017). This planned interchange indirectly prompted another project: the New Jersey Turnpike Authority extended the 'dual-dual' configuration (inner car lanes and outer truck / bus / car lanes) to Interchange 6 in Mansfield Township, Burlington County from its former end at Interchange 8A in Monroe Township, Middlesex County. This widening was completed in early November 2014.
Mercer hosts several New Jersey Transit stations, including Trenton, Hamilton, and Princeton Junction on the Northeast Corridor Line. SEPTA provides rail service to Center City Philadelphia from Trenton and West Trenton. Long-distance transportation is provided by Amtrak train service along the Northeast Corridor through the Trenton Transit Center.
Mercer County's only commercial airport, and one of three in the state, is Trenton-Mercer Airport in Ewing Township, which is served by Frontier Airlines, offering nonstop service to and from points nationwide.
Municipalities in Mercer County (with 2010 Census data for population, housing units and area) are:
Mercer County is also the home of the minor league baseball team, the Trenton Thunder (Eastern League Double-A affiliate of the New York Yankees) and the Trenton Freedom of the Professional Indoor Football League. The minor league hockey team, the Trenton Titans, established in 1999 and operating as the ECHL affiliate of the NHL's Philadelphia Flyers and the AHL's Adirondack Phantoms, disbanded before the start of the 2013-14 season.
Mercer County is also home to several college athletic programs.
