Which of the following is NOT one of the four types of local government units in New Jersey?

In the context of local government units in New Jersey, it's essential to understand the classifications that exist. Counties, school districts, and special districts are all recognized forms of local government, each serving distinct purposes and functions within the state.

Counties are the primary subdivisions of the state, providing various local government services. School districts are responsible for managing local public education and ensuring educational services are provided to students within their jurisdictions. Special districts have a narrower focus and are often created for a specific purpose, such as parks, water supply, or fire protection, allowing for tailored governance to address community needs.

Cities, on the other hand, are considered a subset of municipalities, which include towns, townships, and boroughs in New Jersey. Municipalities operate as local governments but are primarily categorized under the broader classification of municipal government rather than as a separate type of local government unit.

Thus, while cities are integral to the structure of local governance in New Jersey, they are not classified as one of the fundamental types of local government units like counties, school districts, and special districts are. This distinction makes the identification of cities as not one of the four main categories pivotal in understanding New Jersey's local government framework.
