County equivalent in the context of "Unorganized Borough, Alaska"

In the United States, an independent city is a city that is not in the territory of any county or counties and is considered a primary administrative division of its state. Independent cities are classified by the United States Census Bureau as "county equivalents" and may also have similar governmental powers to a consolidated city-county or a unitary authority. However, in the case of a consolidated city-county, a city and a county were merged into a unified jurisdiction in which the county at least nominally exists to this day, whereas an independent city was legally separated from any county or merged with a county that simultaneously ceased to exist even in name.

Of the 41 independent U.S. cities, 38 are in Virginia, whose state constitution makes them a special case. The three independent cities outside Virginia are Baltimore, Maryland; St. Louis, Missouri; and Carson City, Nevada. Baltimore is the most populous independent city in the United States.

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.

There are 41 independent cities in the United States. In Virginia, any municipality that is incorporated as a city legally becomes independent of any county. Where indicated, the statistics below do not include Virginia's 38 independent cities.

Most U.S. states and territories have at least two tiers of local government: counties and municipalities. Louisiana uses the term parish and Alaska uses the term borough for what the U.S. Census Bureau terms county equivalents in those states. Civil townships or towns are used as subdivisions of a county in 20 states, mostly in the Northeast and Midwest.

Population centers may be organized into incorporated municipalities of several types, including the city, town, borough, and village. The types and nature of these municipal entities are defined by state law, and vary from state to state. In addition to these general-purpose local governments, states may also create special-purpose local governments. Depending on the state, local governments may operate under their own charters or under general law, or a state may have a mix of chartered and general-law local governments. Generally, in a state having both chartered and general-law local governments, the chartered local governments have more local autonomy and home rule. Municipalities are typically subordinate to a county government, with some exceptions. Certain cities, for example, have consolidated with their county government as consolidated city-counties. In Virginia, cities are completely independent from the county in which they would otherwise be a part. In some states, particularly in New England, towns form the primary unit of local government below the state level, in some cases eliminating the need for county government entirely. Many rural areas and even some suburban areas of many states have no municipal government below the county level.

In Connecticut, councils of governments, also known as COGs, are regional planning organizations that bring together the chief elected officials or professional managers from member municipalities in Connecticut. Since 2015 and 2022, the Connecticut planning regions served by COGs have been recognized as county equivalents under state and federal law respectively, superseding the eight legacy counties in the state for most federal funding and statistical purposes.

The COGs are meant to aid coordination among neighboring cities and towns, and between the towns and the state government, on issues including land use, zoning, and transportation. They serve some functions analogous to county governments in other states, but have no independent taxing authority (Connecticut disbanded county governments in 1960). Councils of government also host some intermunicipal services based on the needs and voluntary participation of member or client municipalities. Councils, or COGs, receive funding through membership dues, state grants, and federal grants.

There are 3,244 counties and county equivalents in the United States. The 50 states of the United States are divided into 3,007 political subdivisions of states called counties. Two hundred thirty-seven other local governments and geographic places are also first-order administrative divisions of their respective state/district/territory, but are not called counties. The United States Census Bureau refers to the latter as county equivalents. The 237 county equivalents include the District of Columbia and 100 equivalents in U.S. territories (such as those in Puerto Rico). The large majority of counties and equivalents were organized by 1970. Since that time, most creations, boundary changes and dissolutions have occurred in Alaska, Virginia, and Connecticut.

Among the 50 states, 44 are partitioned entirely into counties, with no county equivalents. Louisiana is instead divided into 64 equivalent parishes, while Alaska is divided into 19 equivalent boroughs and 11 sparsely populated census areas, the latter also known collectively as the unorganized borough. Virginia is composed of a mixture of 95 counties and 38 independent cities. Maryland, Missouri and Nevada are each composed entirely of counties, except that each also has exactly one independent city: Baltimore, St. Louis, and Carson City, respectively. The District of Columbia is a single federal district that is not part of any state or county. All of the above 136 exceptional cases are reckoned as county equivalents. The number of counties (or equivalents) per state ranges from the three counties of Delaware, to the 254 counties of Texas. In New England, where the town model predominates, several counties have no corresponding local governments, existing only as historical, legal, and census boundaries, such as the counties of Rhode Island, as well as eight of Massachusetts' 14 counties. On June 6, 2022, the U.S. Census Bureau formally recognized Connecticut's nine councils of government as county equivalents instead of the state's eight counties. Connecticut's eight historical counties continue to exist in name only, and are no longer considered for statistical purposes. In total, the 50 states consist of 3,144 counties and equivalents.
