Subdivisions

In the American federal system, sovereign powers are shared between two levels of elected government: national and state. People in the states are also represented by local elected governments, which are administrative divisions of the states. States are subdivided into counties or county equivalents, and further divided into municipalities. The District of Columbia is a federal district that contains the capital of the United States, the city of Washington. The territories and the District of Columbia are administrative divisions of the federal government. Federally recognized tribes govern 326 Indian reservations.
