Counties are Counties of the ________.

The correct answer is that counties are Counties of the state. This is grounded in the understanding of how governmental structure operates in the United States. Counties serve as subdivisions of states, established to administer local governance, provide services, and enforce laws within their geographic areas. Each state has the authority to create, manage, and govern its counties, which allows for administrative functions to be carried out closer to the population they serve.

Counties have distinct powers defined by state constitutions and laws, enabling them to operate effectively in matters such as law enforcement, public health, and local land use. This relationship underscores their role as entities functioning under the jurisdiction of their respective states, rather than operating independently or as subdivisions of a larger geography such as a nation or city.
