Political divisions (or administrative divisions) of the United States are the various recognized governing entities that together form the United States — states, territories, the District of Columbia, and Indian reservations.
The primary first-level political (administrative) division of the United States is the state. There are 50 states, which are bound together in a union with each other. Each state holds governmental jurisdiction over a defined geographic territory, and shares its sovereignty with the United States federal government. According to numerous decisions of the United States Supreme Court, the 50 individual states and the United States as a whole are each sovereign jurisdictions.
All state governments are modeled after the federal government and consist of three branches (although the three-branch structure is not Constitutionally required): executive, legislative, and judicial. They retain plenary power to make laws covering anything not preempted by the U.S. Constitution, federal statutes, or treaties ratified by the U.S. Senate, and are organized as presidential systems where the governor is both head of government and head of state (even though this too is not required). The various states are then typically subdivided into counties. Louisiana uses the term parish and Alaska uses the term borough for what the Census terms county equivalents in those states.
Counties and county equivalents may be further subdivided into townships. Towns in New York, Wisconsin and New England are treated as equivalents to townships by the United States Census Bureau. 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 cities, towns, villages, and other types of municipalities. 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.
The government of each of the five permanently inhabited U.S. territories is also modeled and organized after the federal government. Each is further subdivided into smaller entities. Puerto Rico has 78 municipalities, and the Northern Mariana Islands has 4 municipalities. Guam has villages, the U.S. Virgin Islands has districts, and American Samoa has districts and unorganized atolls.
Other U.S. sub-national divisions include the District of Columbia, several minor outlying islands, and Indian reservations, all of which are administered by the Federal government. Each Indian Reservation is subdivided in various ways. For example, the Navajo Nation is subdivided into agencies and Chapter houses, while the Blackfeet Nation is subdivided into Communities. The Federal government also maintains exclusive jurisdiction over military installations and American embassies and consulates located in foreign countries. Other special purpose divisions exist separately from those for general governance, examples of which include conservation districts and Congressional districts.
According to the U.S. Internal Revenue Service,
Federal and state governments are established and recognized by the U.S. Constitution and state constitutions. Federally recognized Indian tribal governments are recognized by the U.S. Constitution, treaties, statutes and court decisions. Other entities may be recognized as governments by state law, court decision, or an examination of facts and circumstances that indicate it has the characteristics of a government, such as powers of taxation, law enforcement and civil authority.
The primary political entity of the United States is the state. Four states—Kentucky, Massachusetts, Pennsylvania, and Virginia—call themselves "commonwealths." The word commonwealth in this context refers to the common "wealth", or welfare, of the public. The term has no legal impact.
In 1777 the 13 colonies that had declared independence from Great Britain one year earlier (July 1776) agreed to the formation of a confederation of states, one with an extremely limited central government. A new national frame of government came into force in 1789, when the current U.S. Constitution replaced the Articles. This constitution incorporates the doctrine of the separation of powers, whereby the federal government is divided into three branches, as well as concepts of federalism, describing the rights and responsibilities of state governments and of the states in relationship to the federal government.
On numerous occasions the United States Supreme Court has affirmed that the 50 individual states and the United States as a whole are each sovereign jurisdictions under the Constitution. Due to the shared sovereignty between each state and the federal government, Americans are citizens of both the federal republic and of the state in which they reside. States, however, are not sovereign in the Westphalian sense in international law which says that each State has sovereignty over its territory and domestic affairs, to the exclusion of all external powers, on the principle of non-interference in another State's domestic affairs, and that each State (no matter how large or small) is equal in international law. Additionally, the 50 U.S. states do not possess international legal sovereignty, meaning that they are not recognized by other sovereign States such as, for example, France, Germany or the United Kingdom.
The 50 states of the United States of America are as follows (this list includes both the postal code abbreviation and the traditional abbreviation for each state):
The 50 states can be divided into regions in many different ways.
The states are divided into smaller administrative regions, called counties in all but two states. In Alaska, the county equivalents are called boroughs (parts of the state which are not included in any borough are considered part of the Unorganized Borough, which itself is divided into census areas), and in Louisiana, the county equivalents are called parishes. Counties have varying degrees of political and legal significance. In some states, mainly in New England, they are primarily used as judicial districts. In other states, counties have broad powers in housing, education, transportation and recreation.
Counties may contain a number of cities, towns, villages, or hamlets, or sometimes just a part of a city. Some cities are consolidated with, and coterminous with, their counties, including Philadelphia, Honolulu, San Francisco, Nashville, and Denver—that is to say, these counties consist in their entirety of a single municipality the government of which also operates as the county government. Some counties, such as Arlington County, Virginia, do not have any additional subdivisions. Some states contain independent cities that are not part of any county. Each of the five boroughs of New York City is coterminous with a county.
In many states, counties are further divided into townships. In New York, Wisconsin and New England, county subdivisions are called towns. States not having such subdivisions may divide counties into other minor civil divisions. The terms "township" and "town" are closely related (in many historical documents the terms are used interchangeably). However, the powers granted to townships or towns vary considerably from state to state. In New England, towns are a principal form of local government, providing many of the functions of counties in other states. In California, by contrast, the pertinent statutes of the Government Code clarify that "town" is simply another word for "city", especially a general law city as distinct from a charter city. Also, in some states, large areas have no general-purpose local government below the county level.
Some townships or other minor civil divisions have governments and political power; others are simply geographic designations. Townships in many states are generally the product of the Public Land Survey System. For more information, see survey township and civil township.
There are approximately 30,000 incorporated cities in the United States, with varying degrees of self-rule.
The United States also holds several other territories, districts, and possessions. As these jurisdictions are not part of one of the various states, sovereignty of them rests solely with Congress, and they are governed by Congress in accord with its plenary power under Article IV, Section 3, Clause 2 of the U.S. Constitution. This governing power includes extraterritorial jurisdiction in overseas military installations, American embassies and consulates located in foreign countries, and research centers and field camps in Antarctica. Additionally, it exercises concurrent jurisdiction to varying degrees with the states in many domestic federal enclaves.
A separate federal district, the District of Columbia (DC), which is under the direct authority of Congress, was formed by the District of Columbia Organic Act of 1801 from land ceded to the Federal Government by the states of Maryland and Virginia; however, the territory ceded by Virginia was returned to that state in 1846. The District does not form part of any state and the United States Congress exercises "exclusive jurisdiction in all cases whatsoever", over the city; however, the District of Columbia Home Rule Act provides for limited home rule, including an elected mayor and city council. Residents of the District can vote in presidential elections, as the Twenty-third Amendment to the United States Constitution grants the District three electors in the Electoral College.
The insular areas of the United States are those U.S. territories that are neither a part of one of the 50 states nor the federal district. They are classified by whether they are incorporated (part of the United States proper) and whether they have an organized government through an Organic Act passed by the U.S. Congress. Insular areas are administered by the Department of the Interior's Office of Insular Affairs.
Since the creation in 1787 of the first territory beyond the existing states, the Northwest Territory, the federal government has established numerous organized incorporated territories, with some political autonomy. These jurisdictions (or portions thereof) subsequently became states. Thirty-one of the current 50 states were organized incorporated territories, or part of one, before their admission to the Union. No incorporated organized territories have existed since 1959 when Alaska and Hawaii joined the Union.
Currently, 5 territories are self-governing. The current inhabited unincorporated territories of the United States and their ISO 3166-1 codes (in parentheses) are as follows:
Guam and Puerto Rico, both gained by the United States in the Spanish–American War, are considered part of the "United States" for purposes of law; on the other hand, the United States Supreme Court declared in a series of opinions known as the Insular Cases that the Constitution extended ex proprio vigore to the territories. However, the Court in these cases also established the doctrine of territorial incorporation. Under the same, the Constitution only applied fully in incorporated territories such as Alaska and Hawaii, whereas it only applied partially in the new unincorporated territories of Puerto Rico, Guam and the Philippines.
Since 1959, there has been a single incorporated territory: Palmyra Atoll (formerly part of the Hawaii Territory, but excluded from the Hawaii Admission Act). The following uninhabited territories, all of which are unorganized, form the United States Minor Outlying Islands (UM):
The United States government is part of several international disputes over the disposition of certain maritime and insular areas, which it claims as territories. Bajo Nuevo Bank and Serranilla Bank are two such disputed claims.
American Indian reservations are areas of land managed by an American Indian tribe under the United States Department of the Interior's Bureau of Indian Affairs. There are about 310 Indian reservations in the United States. Tribes possess limited tribal sovereignty over the land in their reservation. As a result, laws on tribal lands may vary from the surrounding area. The tribal council, not the county or state government, generally has jurisdiction over reservations. Different reservations have different systems of government, which may or may not replicate the forms of government found outside the reservation. Most Indian reservations were established by the federal government; a limited number, mainly in the East, owe their origin to state recognition.
Residents of a reservation may vote as residents of a state and are required to pay federal taxes. The special status of reservations has created both opportunities (such as gambling in states that normally disallow it) and challenges (such as the unwillingness of some companies to do business in an area where they are not certain what laws will apply to them).
The two former unincorporated U.S. territories are:
Additionally, the United States administered the Trust Territory of the Pacific Islands from July 18, 1947 until October 1, 1994. The trust territory was subsequently divided into four political entities. One, the Northern Mariana Islands, listed above, became an unincorporated U.S. territory, while three—Federated States of Micronesia, Marshall Islands, and Palau—became independent nations. All three have become freely associated with the United States under a Compact of Free Association.
Article IV, Section 3 of the Constitution for the United States of America defines the extent of the authority that the U.S. Congress exercises over the territory of the United States:
The power of Congress over territorial divisions that are not part of one of the states is exclusive and universal. Once a territory becomes a state of the Union, the state must consent to any changes pertaining to the jurisdiction of that state. The only potential violation of this occurred when the legislature of Virginia declared the secession of Virginia from the United States at the start of the American Civil War and a newly formed alternative Virginia legislature, recognized by the federal government, consented to have West Virginia secede from Virginia.
On March 3, 1849, the last day of the 30th Congress, a bill was passed to create the U.S. Department of the Interior to take charge of the internal affairs of United States territory. The Interior Department has a wide range of responsibilities (which include the regulation of territorial governments, the basic responsibilities for public lands, and other various duties).
In contrast to similarly named Departments in other countries, the United States Department of the Interior is not responsible for local government or for civil administration except in the cases of Indian reservations, through the Bureau of Indian Affairs (BIA), and island dependencies, through the Office of Insular Affairs (OIA).
In addition to general-purpose government entities legislating at the state, county, and city level, special-purpose areas may exist as well. Conservation districts are one such type of special purpose area, created for the purpose of conserving land, natural scenery, flora, and fauna. Congressional districts are another example, formed for the purpose of electing members to the United States Congress.
independent, special-purpose governmental units (other than school district governments) that exist as separate entities with substantial administrative and fiscal independence from general-purpose local governments. Special district governments provide specific services that are not being supplied by existing general-purpose governments. Most perform a single function, but, in some instances, their enabling legislation allows them to provide several, usually related, types of services. The services provided by these districts range from such basic social needs as hospitals and fire protection to the less conspicuous tasks of mosquito abatement and upkeep of cemeteries. The Census Bureau classification of special district governments covers a wide variety of entities, most of which are officially called districts or authorities.
Additionally, U.S. courts have ruled that there are smaller areas which are to be considered as fulfilling government functions, and should therefore be bound by the same restrictions placed on "traditional" local government bodies. These include homeowners associations (determined in Shelley v. Kraemer, Loren v. Sasser, Committee for a Better Twin Rivers v. Twin Rivers Homeowners' Association), and company-owned towns (both for employees and for consumers, decided in the USSC case Marsh v. Alabama in 1946). Many homeowners' and neighborhood associations are considered non-profit organizations, but have the ability to raise taxes or fees, fine members for infractions against association-rules, and initiate lawsuits. The question of civil rights in such communities has not yet been conclusively determined, and varies from state to state.
A civil township is a widely used unit of local government in the United States that is subordinate to a county. The term town is used in New England, New York, and Wisconsin to refer to the equivalent of the civil township in these states. Specific responsibilities and the degree of autonomy vary based on each state. Civil townships are distinct from survey townships, but in states that have both, the boundaries often coincide and may completely geographically subdivide a county. The U.S. Census Bureau classifies civil townships as minor civil divisions. Currently, there are 20 states with civil townships.
Township functions are generally overseen by a governing board (the name varies from state to state) and a clerk or trustee. Township officers frequently include justice of the peace, road commissioner, assessor, constable, and surveyor. In the 20th century, many townships also added a township administrator or supervisor to the officers as an executive for the board. In some cases, townships run local libraries, senior citizen services, youth services, disabled citizen services, emergency assistance, and even cemetery services. In some states, a township and a municipality that is coterminous with that township may wholly or partially consolidate their operations.Hoot and Holler Crossing, Texas

The following is an alphabetical list of articles related to the United States Territory of Guam.Insular area
An insular area of the United States is a U.S. territory that is neither a part of one of the 50 states nor of a Federal district. Article IV, Section 3, Clause 2 of the United States Constitution grants to United States Congress the responsibility of overseeing these territories, of which there are currently 14—three in the Caribbean Sea and 11 in the Pacific Ocean. These territories are classified by whether they are incorporated (by Congress extending the full body of the Constitution to the territory as it applies to the several states) and whether they have an organized territorial government established by the U.S. Congress through an Organic Act. All territories but one are unincorporated, and all but four are considered to be unorganized. Five U.S. territories have a permanent, nonmilitary population. Each of them has a civilian government, a constitution, and enjoys some degree of local political autonomy.List of U.S. state abbreviations
Several sets of codes and abbreviations are used to represent the political divisions of the United States for postal addresses, data processing, general abbreviations, and other purposes.List of river borders of U.S. states
Because of its unique history, many of the boundaries of the political divisions of the United States were artificially constructed (rather than being permitted to evolve and drawn using natural features of the landscape). Therefore, many U.S. states have straight lines as boundaries, especially in the West. However, there are a number of states, particularly in the Midwest, North and South with at least partial river borders.List of states and territories of the United States
The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico; the two other states, Alaska and Hawaii, are in the northwestern part of North America and an archipelago in the mid-Pacific, respectively, while the territories are scattered throughout the Pacific Ocean and the Caribbean Sea.
States are the primary subdivisions of the United States, and possess a number of powers and rights under the United States Constitution, such as regulating intrastate commerce, running elections, creating local governments, and ratifying constitutional amendments. Each state has its own constitution, grounded in republican principles, and government, consisting of three branches: executive, legislative, and judicial. All states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two Senators, while Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the President of the United States, equal to the total of Representatives and Senators in Congress from that state. Article IV, Section 3, Clause 1 of the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to the current total of 50, and each new state is admitted on an equal footing with the existing states.As provided by Article I, Section 8 of the Constitution, Congress exercises "exclusive jurisdiction" over the federal district, which is not part of any state. Prior to passage of the 1973 District of Columbia Home Rule Act, which devolved certain Congressional powers to an elected mayor and council, the district did not have an elected local government. Even so, Congress retains the right to review and overturn laws created by the council and intervene in local affairs. As it is not a state, the district does not have representation in the Senate. However, since 1971, its residents have been represented in the House of Representatives by a non-voting delegate. Additionally, since 1961, following ratification of the 23rd Amendment, the district has been entitled to select three electors to vote in the Electoral College.
In addition to the 50 states and federal district, the United States has sovereignty over 14 territories. Five of them (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands) have a permanent, nonmilitary population, while nine of them do not. With the exception of Navassa Island, Puerto Rico, and the U.S. Virgin Islands, which are located in the Caribbean, all territories are located in the Pacific Ocean. One territory, Palmyra Atoll, is considered to be incorporated, meaning the full body of the Constitution has been applied to it; the other territories are unincorporated, meaning the Constitution does not fully apply to them. Ten territories (the Minor Outlying Islands and American Samoa) are considered to be unorganized, meaning they have not had an Organic Act enacted by Congress; the four other territories are organized, meaning they have had an Organic Act that has been enacted by Congress. The five inhabited territories each have limited autonomy and a non-voting delegate in Congress, in addition to having territorial legislatures and governors, but residents cannot vote in federal elections.
California is the most populous state, with 38,332,521 residents (2013 estimate); Wyoming is the least populous, with an estimated 582,658 residents. The District of Columbia, with an estimated 646,449 residents as of 2012, has a higher population than the two least populous states (Wyoming and Vermont). The largest state by area is Alaska, encompassing 665,384 square miles (1,723,340 km2), while the smallest is Rhode Island, encompassing 1,545 square miles (4,000 km2). The first state to ratify the current Constitution was Delaware, which it did on December 7, 1787, while the newest state is Hawaii, which was admitted to the Union on August 21, 1959. The largest territory in terms of both population and size is Puerto Rico, with 3,725,789 residents as of the 2010 Census and a total area of 5,325 square miles (13,790 km2).Mulkeytown, Illinois
Mulkeytown is an unincorporated and census-designated place in Franklin County, Illinois, United States. As of the 2010 census it had a population of 175.Organized incorporated territories of the United States
Organized incorporated territories are territories of the United States that are both incorporated (part of the United States proper) and organized (having an organized government authorized by an Organic Act passed by the U.S. Congress, usually consisting of a territorial legislature, territorial governor, and a basic judicial system). There have been no such territories since Alaska and Hawaii were admitted as states in 1959.
Through most of U.S. history, regions that were admitted as U.S. states were, prior to admission, territories or parts of territories of this kind. As the United States grew, the most populous parts of the organized territory would achieve statehood. The remainder frequently kept at least some of the governing structure of the old legal entity (territory) and would be renamed to avoid confusion.
Some territories existed only a short time before becoming states, while others remained territories for decades. The shortest-lived was Alabama Territory at two years, while New Mexico Territory and Hawaii Territory both lasted more than 50 years.Outline of North Dakota territorial evolution

State governments of the United States are institutional units in the United States exercising some of the functions of government at a level below that of the federal government. Each state's government holds legislative, executive, and judicial authority over a defined geographic territory. The United States comprises 50 states: 13 that were already part of the United States at the time the present Constitution took effect in 1789, plus 37 that have been admitted since by Congress as authorized under Article IV, Section 3 of the Constitution.Territorial evolution of Arizona

Under United States law, an unincorporated territory is an area controlled by the United States government that is not part of (i.e., "incorporated" in) the United States. In unincorporated territories, the U.S. Constitution applies only partially. In the absence of an organic law, a territory is classified as unorganized. In unincorporated territories, "fundamental rights apply as a matter of law, but other constitutional rights are not available". Selected constitutional provisions apply, depending on congressional acts and judicial rulings according to U.S. constitutional practice, local tradition, and law.There are currently thirteen unincorporated territories, comprising a land area of approximately 12,000 square kilometers (4,600 square miles) containing a population of approximately four million people; Puerto Rico alone comprises the vast majority of both the total area and total population.Of the thirteen territories, five are inhabited. These are either organized or self-governing but unincorporated. These are Puerto Rico, Guam, Northern Mariana Islands, U.S. Virgin Islands, and American Samoa. There are also nine uninhabited U.S. possessions, of which only Palmyra Atoll is incorporated. (See Territories of the United States, Unorganized territory and insular area.)
