New Jersey has 21 counties and 13 congressional districts: 7 counties are wholly within a given congressional district; 14 counties are divided among more than one congressional district.

In the State of New Jersey, the General Law County Subdivision is the Township; however, there are also the following types of Municipalities: Cities, Towns, Boroughs and Villages. Under New Jersey law, Townships and Municipalities are equivalent- the Townships have the same general powers as any Municipality while Municipalities are completely separate from the Township(s) from which they were once created: therefore, all Townships and Municipalities are Minor Civil Divisions of the first order in New Jersey and, because of this, Townships are often referred to as "Municipalities" in lists of local governmental units, while Municipalities are often referred to as "Townships" (particularly in court records and other legal documents). To make matters even more confusing, the type of local governmental unit may not necessarily reflect the type of local government it actually has (e.g., there are Townships with "Town Government", etc.). To avoid any such confusion in the listing of the Congressional Districts re: the Minor Civil Divisions/local governmental units of New Jersey below, no reference will be made to the type of Municipality/Township unless there are two or more such units in a given County with the same- or a similar- name:
