Hunterdon County is a county located in the western section of the U.S. state of New Jersey. As of the 2020 United States Census, the county's population was 128,947, making it the state's 18th-most populous county, representing an increase of 598 (0.5%) from the 128,349 enumerated in the 2010 United States Census, which in turn increased by 6,360 (5.2%) from the 121,989 counted in the 2000 Census. Its county seat is Flemington.

In 2015, the county had a per capita personal income of $80,759, the third-highest in New Jersey and ranked 33rd of 3,113 counties in the United States. The Bureau of Economic Analysis ranked the county as having the 19th-highest per capita income of all 3,113 counties in the United States (and the highest in New Jersey) as of 2009. Hunterdon County is noted for having the second-lowest level of child poverty of any county in the United States.

Geographically, much of the county lies in the Delaware Valley as a geographic concept, that is, the drainage basin of the Delaware River. Local businesses and the Delaware Valley Regional High School carry the name. However, "Delaware Valley" is also used to refer to the Philadelphia-Reading-Camden Combined Statistical Area (CSA), and Hunterdon County does not belong to the Philadelphia CSA, but rather to the New York-Northern New Jersey-Long Island Metropolitan Statistical Area (MSA), part of the larger New York-Newark Combined Statistical Area (CSA). It is located within the state's Skylands Region.

Hunterdon County was established on March 11, 1714, separating from Burlington County, at which time it included all of present-day Morris, Sussex and Warren counties. The rolling hills and rich soils which produce bountiful agricultural crops drew Native American tribes and then Europeans to the area.


Around 500 million years ago, a chain of volcanic islands shaped like an arch collided with proto North America and rode over the top of the North American plate. The rock from the islands created the highlands of Hunterdon County as there was a shallow sea where Hunterdon County is now located. Then around four hundred million B.C., a small continent that was long and thin, collided with proto North America. This collision created compression, which caused heat. The Paleozoic sediment of shale and sandstone folded and faulted. The heat allowed the igneous rock to bend, thus Hunterdon County was born.

The African plate which later collided with North America created more folding and faulting, especially in the southern Appalachians. Then the African and North America plates tore and drifted away from each other.

The Wisconsin glacier that entered into New Jersey around 21,000 BCE and then melted around 13,000 BCE did not reach Hunterdon County. However, there are glacial outwash deposits from streams and rivers that flowed from the glacier southward depositing rock and sediment.

Hunterdon County has two geophysical provinces. The first is the Highlands which is the western section of the county. The other is the Piedmont which is the eastern and southern section of the county. The Highlands account for one third of the area and the Piedmont accounts for two thirds of the county.

The Highlands are part of the Reading Prong. Limestone and shale over igneous rock comprise the Highlands.

The Piedmont includes the Hunterdon Plateau and the Raritan Valley Lowlands which are 150 to 300 feet (46 to 91 m) above sea level. The Piedmont is made up of shale and sandstone.

Paleo Indians and Native Americans

Paleo Indians moved into Hunterdon County between 12,000 BCE and 11,000 BCE. The area was warming due to climate change. The Wisconsin Glacier in Warren and Sussex County was retreating northward. The area was that of Taiga/Boreal forests. Paleo Indians traveled in small groups in search of game and edible plants. They used spears made of bone, jasper or black chert. Their camp sites are difficult to find as they are many feet below the present surface.

Native Americans moved into the area but the time they arrived is unknown. Most have come from the Mississippi River area. Many tribes of the Delaware Nation lived in Hunterdon County especially along the Delaware River and in the Flemington area. These tribes were agricultural in nature, growing corn, beans and squash. Those that lived along the South Branch of the Raritan River fished and farmed. There was a Native American trail that went along the South Branch of the Raritan River (Philhower 1924).

European settlement

Land purchases from Native Americans occurred from 1688 to 1758. Large land purchases from Native Americans occurred in 1703, 1709 and 1710. Over 150,000 acres (610 km2) were bought with metal knives and pots, clothing, blankets, barrels of rum or hard cider, guns, powder and shot. This allowed for European settlers to enter into Hunterdon County in the early 18th century. After 1760 nearly all Native Americans left New Jersey and relocated to eastern Canada or the Mississippi River area.

The first European settlers were Col. John Reading who settled in Reading Township in 1704 and John Holcombe who settled in Lambertville in 1705.

County origin

Hunterdon County was separated from Burlington County on March 11, 1714. At that time Hunterdon County was large, going from Assunpink Creek near Trenton to the New York State line which at that time was about 10 miles (16 km) north of Port Jervis, New York. Hunterdon County was named for Robert Hunter, a colonial governor of New Jersey. Language changes over time and location, so by stemming of [s], and a [t] → [d] lenition of the name of his family seat of "Hunterston" in Ayrshire, Scotland, the name "Hunterdon" was derived.

On March 15, 1739, Morris County (which at the time included what would later become Sussex County and Warren County) was separated from Hunterdon County. The boundary between Hunterdon and Somerset counties is evidence of the old Keith Line which separated the provinces of West Jersey and East Jersey.

Hunterdon County was reduced in area on February 22, 1838, with the formation of Mercer County from portions of Burlington County, Hunterdon County and Middlesex County. In February 1839, the remaining portion of Hopewell Township was annexed to Mercer County. On March 13, 1844 Hopewell Township returned to Hunterdon County while Tewksbury Township was annexed by Somerset County but in February 1845 both of these changes were repealed. Since then, the county boundaries have remained the same.

Hunterdon County was being affected by industrialization in the state and nation, mining speculation in northwest New Jersey, and competitors constructing railroads. The Elizabethtown and Somerville Railroad leased a section to White House just south of Tewksbury Township in 1848.

Recent history

Transitioning from rural to suburban, Hunterdon County is an exurb on the western edge of New Jersey and home to commuters to New York City and Philadelphia. The county seat, Flemington, is noted as the site of the Lindbergh kidnapping trial which convicted Bruno Hauptmann of the murder of aviator Charles Lindbergh's son. With growing towns and shopping areas, as well as relaxing rural areas, Hunterdon County is a far stretch from the urban areas stereotypically associated with New Jersey.


According to the 2010 Census, the county had a total area of 437.44 square miles (1,133.0 km2), including 427.82 square miles (1,108.0 km2) of land (97.8%) and 9.62 square miles (24.9 km2) of water (2.2%).

Much of the county is hilly, with several hills rising to one thousand foot in elevation. The highest points are two areas in Lebanon Township, one on the Morris County line, both reaching approximately 1,060 feet (320 m) above sea level. The first is at Smith on the Morris County line and the second is north of the area called Little Brook. This area is known as the Highlands of New Jersey. The lowest elevation is where the Mercer County line reaches the Delaware River, approximately 50 feet (15 m) above sea level. The county is drained by the Musconetcong River in the north. The river flows in a southwest direction. The Lamington River drains the county in the east. The central portion of the county is drained by the South Branch of the Raritan River. The Delaware River drains the western side of the county.

Adjacent counties

The county borders the following:

Hunting and fishing

Hunterdon County is considered the premier place to hunt white tailed deer in New Jersey. More deer are harvested each year than any other county according to New Jersey Fish and Game records.

The premier fishing streams are the Musconetcong in the north and the Lamington River. The NJ Fish and Game stocks thousands of rainbow, brown, and brook trout in these streams as well as other streams such as the South Branch of the Raritan River.

There is also Round Valley Reservoir and Spruce Run Reservoir. Both are manmade reservoirs that provide boating and fishing opportunities for patrons. Round Valley is one of New Jersey's trophy trout lakes, the reservoir holds the state records for smallmouth bass, brown trout, lake trout, and American eel. Spruce Run held the state record for Northern Pike for nearly 30 years, and offers a large variety of species for anglers to pursue.

New Jersey Fish and Game has also many Wildlife Management Areas for hunting ducks, deer, pheasants, quail, rabbits, squirrels and bears.

Income and taxes

Hunterdon County ranked as the 7th among the highest-income counties in the United States with a per capita income of $36,370. It ranks fourth among U.S. counties for household income according to the most recent data from the U.S. Census Bureau. Hunterdon County's median household income was $99,099, behind only Loudoun County, Fairfax County, and Arlington County, Virginia. As of 2005, Hunterdon had the third-highest median property tax of any county in the nation at $6,988, the highest in New Jersey. As of the Tax Foundation's rankings based on 2006 data, Hunterdon had taken the top spot for highest median property tax at $7,999.

As of 2011, Hunterdon still had the nation's highest taxes, with a median of $8,216.
