Hunterdon County is a county located in the western section of the U.S. state of New Jersey. As of the 2010 United States Census, the population was 128,349. It is part of the New York Metropolitan Area. Its county seat is Flemington. 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 third highest in New Jersey) as of 2009.
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.
