# Union Township, Hunterdon County, New Jersey

Union Township is a township in Hunterdon County, in the U.S. state of New Jersey. The southwest half of the township lies on what is known as the Hunterdon Plateau, the northwest corner consists of the Musconetcong Ridge and the northeast section is part of the lower-lying Newark Basin around Spruce Run Reservoir. As of the 2020 United States census, the township's population was 6,507, its highest ever decennial count and an increase of 599 (+10.1%) from the 2010 census count of 5,908, which in turn reflected a decline of 252 (−4.1%) from the 6,160 counted in the 2000 census.
Union was incorporated as a township by an act of the New Jersey Legislature on February 17, 1853, from portions of Bethlehem Township. Clinton Town was formed on April 5, 1865, within portions of the township, and became an independent municipality in 1895. The township was named for Union Furnace, which was producing iron from 1742 until the 1780s. The name "Union" was chosen over the alternative "Rockhill", which was a community at the southern end of the township.
Union Furnace and its forge produced cannonballs for the Revolutionary War and shoes for horses and oxen, as well as farm implements. Farms and fields were established in areas where trees were felled to provide fuel for the furnace. A farm community developed, together with basket making and tanning industries.
New Jersey Monthly magazine ranked Union Township 21st in its 2008 rankings of the "Best Places To Live" in New Jersey.

## Geography

According to the United States Census Bureau, township had a total area of 20.63 square miles (53.43 km$^2$), including 18.77 square miles (48.60 km$^2$) of land and 1.86 square miles (4.83 km$^2$) of water (9.03%).

## Demographics

Two large state facilities in the township, the Edna Mahan Correctional Facility for Women (with 650 inmates in 2018) and Hunterdon Developmental Center (which had 480 residents as of 2017), account for almost 20% of the residents counted by the Census Bureau. Their inclusion skews the township's demographic characteristics. The unusual ratio of 100 females there vs. 77.5 males and the presence of 12.5% of residents but no families being below the poverty linen is largely due to the nature of the residents of these two facilities.
