Hunterdon County is a county located in the western section of the U.S. state of New Jersey. As of the 2017 Census estimate, the county’s population was 125,059, making it the state’s 18th-most populous county,
representing a 2.6% decrease from the 128,349 enumerated in the 2010 United States Census, in turn increasing by 6,360 (+5.2%) from the 121,989 counted in the 2000 Census, retaining its position as the state’s 14th-most populous county. The percentage increase in population of 13.2% between 1990 and 2000 was the largest in New Jersey, almost triple the statewide increase of 4.5%, and the absolute increase in residents was the third highest. 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.
It is part of the Newark-Union, NJ-PA Metropolitan Division of the New York-Northern New Jersey-Long Island, NY-NJ-PA Metropolitan Statistical Area. However, some portions of the county include themselves as part of the Delaware Valley, though Hunterdon County is not officially included in that area.
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.
