The United States of America is a federal republic [1] consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. [2] [3] Both the states and the United States as a whole are each sovereign jurisdictions. [4] The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and 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. [5] 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. [6] The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states. [7]

The United States has control over fourteen 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 (the United States Minor Outlying Islands) 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 an organic act has been enacted by Congress. The five inhabited territories each have limited autonomy in addition to having territorial legislatures and governors, but residents cannot vote in federal elections, although all are represented by non-voting delegates in the House.

The largest state by population is California, with a population of 39,538,223 people, while the smallest is Wyoming, with a population of 576,851 people; the federal district has a larger population (689,545) than both 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 most recent states to be admitted, Alaska and Hawaii, were admitted in 1959. The largest territory by population is Puerto Rico, with a population of 3,285,874 people (larger than 21 states), while the smallest is the Northern Mariana Islands, with a population of 47,329 people. Puerto Rico is the largest territory by area, encompassing 5,325 square miles (13,790 km2); the smallest territory, Kingman Reef, encompasses only 0.005 square miles (0.013 km2).

Puerto Rico, officially the Commonwealth of Puerto Rico, is a Caribbean island, Commonwealth, and unincorporated territory of the United States. It is located in the northeast Caribbean Sea, approximately 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic and the U.S. Virgin Islands, and includes the eponymous main island and several smaller islands, such as Mona, Culebra, and Vieques. With roughly 3.2 million residents, it is divided into 78 municipalities, of which the most populous is the capital municipality of San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates.

<span class="mw-page-title-main">Contiguous United States</span> 48 states of the United States apart from Alaska and Hawaii

The contiguous United States consists of the 48 adjoining U.S. states and the District of Columbia of the United States of America in central North America. The term excludes the only two non-contiguous states, which are Alaska and Hawaii, and all other offshore insular areas, such as the U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term "Lower 48" is also used, especially in relation to Alaska.

A dependent territory, dependent area, or dependency is a territory that does not possess full political independence or sovereignty as a sovereign state and remains politically outside the controlling state's integral area. As such, a dependent territory includes a range of non-integrated not fully to non-independent territory types, from associated states to non-self-governing territories.

In the United States, a territory is any extent of region under the sovereign jurisdiction of the federal government of the United States, including all waters. The United States asserts sovereign rights for exploring, exploiting, conserving, and managing its territory. This extent of territory is all the area belonging to, and under the dominion of, the United States federal government for administrative and other purposes. The United States total territory includes a subset of political divisions.

The 51st state in American political discourse refers to the concept of granting statehood to one of the United States' territories, splitting one or more of the existing states up to form a new state, or granting statehood to the District of Columbia, thereby increasing the number of states in the Union from 50 to 51.

<span class="mw-page-title-main">Insular area</span> U.S. territory that is neither a U.S. state nor the District of Columbia

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.

<span class="mw-page-title-main">Territories of the United States</span>

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 Insular Cases are a series of opinions by the Supreme Court of the United States in 1901 about the status of U.S. territories acquired in the Spanish–American War. Some scholars also include cases regarding territorial status decided up until 1914, and others include related cases as late as 1979. The term "insular" signifies that the territories were islands administered by the War Department's Bureau of Insular Affairs. Today, the categorizations and implications put forth by the Insular Cases still govern the United States' territories.

Commonwealth is a term used by two unincorporated territories of the United States in their full official names, which are the Northern Mariana Islands, whose full name is Commonwealth of the Northern Mariana Islands, and Puerto Rico, which is named Commonwealth of Puerto Rico in English and Estado Libre Asociado de Puerto Rico in Spanish, translating to "Free Associated State of Puerto Rico." The term was also used by the Philippines during most of its period under U.S. sovereignty, when it was officially called the Commonwealth of the Philippines.

<span class="mw-page-title-main">Office of Insular Affairs</span> Subsidiary of the Department of the Interior

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").

The United States territorial courts are tribunals established in territories of the United States by the United States Congress, pursuant to its power under Article Four of the United States Constitution, the Territorial Clause. Most United States territorial courts are defunct because the territories under their jurisdiction have become states or been retroceded.

<span class="mw-page-title-main">U.S. state</span> Constituent polity of the United States

In the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders.

<span class="mw-page-title-main">District of Columbia and United States Territories quarters</span> Series of U.S. coins

The District of Columbia and United States Territories quarters were a series of six quarters minted by the United States Mint in 2009 to honor the District of Columbia and the unincorporated United States insular areas of Puerto Rico, Guam, the United States Virgin Islands, American Samoa, and the Northern Mariana Islands. The islands commonly grouped together as the United States Minor Outlying Islands were not featured, as the law defined the word "territory" as being limited to the areas mentioned above. They followed the completion of the 50 State Quarters Program. The coins used the same George Washington obverse as with the quarters of the previous 10 years. The reverse of the quarters featured a design selected by the Mint depicting the federal district and each territory. Unlike on the 50 State quarters, the motto "E Pluribus Unum" preceded and was the same size as the mint date on the reverse.

<span class="mw-page-title-main">Puerto Rico statehood movement</span> Movement to grant Puerto Rico U.S. statehood

The Puerto Rico statehood movement aims to make Puerto Rico a state of the United States. Puerto Rico is an unincorporated territorial possession of the United States acquired in 1898 following the Spanish–American War, making it "the oldest colony in the modern world". As of 2023, the population of Puerto Rico is 3.2 million, around half the average state population and higher than that of 19 U.S. states. Statehood is one of several competing options for the future political status of Puerto Rico, including: maintaining its current status, becoming fully independent, or becoming a freely associated state. Puerto Rico has held six referendums on the topic. These are non-binding, as the power to grant statehood lies with the US Congress. The most recent referendum was in November 2020, with a majority (52.52%) of those who voted opting for statehood.

<span class="mw-page-title-main">Political status of Puerto Rico</span> Unincorporated territory of the United States

The political status of Puerto Rico is that of an unincorporated territory of the United States officially known as the Commonwealth of Puerto Rico. As such, the island of Puerto Rico is neither a sovereign nation nor a U.S. state.

<span class="mw-page-title-main">American Samoan citizenship and nationality</span> Application of United States nationality and citizenship in American Samoa

American Samoa consists of a group of two coral atolls and five volcanic islands in the South Pacific Ocean of Oceania. The first permanent European settlement was founded in 1830 by British missionaries, who were followed by explorers from the United States, in 1839, and German traders in 1845. Based upon the Tripartite Convention of 1899, the United States, Great Britain, and Germany agreed to partition the islands into German Samoa and American Samoa. Though the territory was ceded to the United States in a series of transactions in 1900, 1904, and 1925, Congress did not formally confirm its acquisition until 1929. American Samoans are non-citizen nationals of the United States. Non-citizen nationals do not have full protection of their rights, though they may reside in the United States and gain entry without a visa. Territorial citizens do not have the ability for full participation in national politics and American Samoans cannot serve as officers in the US military or in many federal jobs, are unable to bear arms, vote in local elections, or hold public office or civil-service positions even when residing in a US state. Nationality is the legal means in which inhabitants acquire formal membership in a nation without regard to its governance type. Citizenship is the relationship between the government and the governed, the rights and obligations that each owes the other, once one has become a member of a nation.
