In 45 of the 50 states of the United States, the county is used for the level of local government immediately below the state itself. Louisiana uses parishes, and Alaska uses boroughs. In Connecticut, Massachusetts, and Rhode Island, some or all counties within states have no governments of their own; the counties continue to exist as legal entities, however, and are used by states for some administrative functions and by the United States Census bureau for statistical analysis. There are 3,242 counties and county equivalent administrative units in total, including the District of Columbia and 100 county-equivalents in the U.S. territories.
Territories of the United States are sub-national administrative divisions overseen by the federal government of the United States. The various American territories differ from the U.S. states and Indian reservations as they are not sovereign entities. In contrast, each state has a sovereignty separate from that of the federal government and each federally recognized Native American tribe possesses limited tribal sovereignty as a "dependent sovereign nation." Territories are classified by incorporation and whether they have an "organized" government through an organic act passed by the Congress. American territories are under American sovereignty and, consequently, may be treated as part of the United States proper in some ways and not others. Unincorporated territories in particular are not considered to be integral parts of the United States, and the Constitution of the United States applies only partially in those territories.
U.S. states, districts, and territories have representative symbols that are recognized by their state legislatures, territorial legislatures, or tradition. Some, such as flags, seals, and birds have been created or chosen by all U.S. polities, while others, such as state crustaceans, state mushrooms, and state toys have been chosen by only a few.

In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured.
