Hunterdon County in the context of "Bureau of Economic Analysis"

Central Jersey, or Central New Jersey, is the middle region of the U.S. state of New Jersey. The designation Central Jersey is a distinct administrative toponym. While New Jersey is often divided into North Jersey and South Jersey, many residents recognize Central Jersey as a distinct third entity. As of the 2020 census, Central Jersey has a population of 3,580,999.

All descriptions of Central Jersey include Middlesex County, the population center of New Jersey, and most include much of nearby Monmouth, Mercer, Somerset, and Hunterdon counties. The inclusion of adjacent Union and Ocean counties on the north and south of the region, respectively, is a source of debate. In 2015, New Jersey Business magazine defined Central Jersey more narrowly as the five counties of Hunterdon, Mercer, Middlesex, Monmouth, and Somerset.
