The United States Minor Outlying Islands is a statistical designation defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM. The minor outlying islands and groups of islands consist of eight United States insular areas in the Pacific Ocean and one in the Caribbean Sea.
In the United States, a county or county equivalent is an administrative or political subdivision of a U.S. state or other territories of the United States which consists of a geographic area with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Some municipalities have been consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. Conversely, those counties in Connecticut, Rhode Island, eight of Massachusetts's 14 counties, and Alaska's Unorganized Borough have no government power, existing only as geographic distinctions.
A minor civil division (MCD) is a term used by the United States Census Bureau for primary governmental and/or administrative divisions of a county or county-equivalent, typically a municipal government such as a city, town, or civil township. MCDs are used for statistical purposes by the Census Bureau, and do not necessarily represent the primary form of local government. They range from non-governing geographical survey areas to municipalities with weak or strong powers of self-government. Some states with large unincorporated areas give substantial powers to counties; others have smaller or larger incorporated entities with governmental powers that are smaller than the MCD level chosen by the Census.

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.
In the law of the United States, an insular area is a U.S.-associated jurisdiction that is not part of a U.S. state or the District of Columbia. This includes fourteen U.S. territories administered under U.S. sovereignty, as well as three sovereign states each with a Compact of Free Association with the United States. The term also may be used to refer to the previous status of the Swan Islands, Hawaii, Puerto Rico, and the Philippines, as well as the Trust Territory of the Pacific Islands when it existed.
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.
The Office of Insular Affairs (OIA) is a unit of the United States Department of the Interior that oversees federal administration of several United States insular areas. It is the successor to the Bureau of Insular Affairs of the War Department, which administered certain territories from 1902 to 1939, and the Office of Territorial Affairs in the Interior Department, which was responsible for certain territories from the 1930s to the 1990s. The word "insular" comes from the Latin word insula ("island").
American Samoa is administratively divided into three districts and two unorganized atolls. The districts are subdivided into 15 counties, which are composed of 76 villages.
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.
The Manuʻa District is one of the three primary administrative divisions of American Samoa. The district comprises the Manuʻa Islands, which are located approximately 61 miles (98 km) east of the main island, Tutuila. The Manuʻa District is considered to be a county-equivalent by the U.S. Census Bureau.
