|a.||"The term 'Commonwealth' does not describe or provide for any specific political status or relationship. It has, for example, been applied to both states and territories. When used in connection with areas under U.S. sovereignty that are not states, the term broadly describes an area that is self-governing under a constitution of its adoption and whose right of self-government will not be unilaterally withdrawn by Congress."|
of the United States
Territories of the United States are sub-national administrative divisions directly overseen by the United States federal government (unlike U.S. states, which share sovereignty with the federal government). The five major territories are self-governing with locally elected governors and territorial legislatures. Each also elects a non-voting member (or resident commissioner) to the U.S. House of Representatives.
Currently, there are sixteen territories of the United States, five of which are permanently inhabited: Puerto Rico, Guam, Northern Mariana Islands, the U.S. Virgin Islands, and American Samoa. Ten territories are small islands, atolls and reefs, spread across the Caribbean and Pacific, with no native or permanent populations: Palmyra Atoll, Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Wake Island, Midway Islands, Navassa Island and Serranilla Bank. Uninhabited Bajo Nuevo Bank is administered by Colombia, but claimed by the United States under the Guano Islands Act.
Historically, territories were created to govern newly acquired land while the borders of the United States were still evolving. Most territories eventually attained statehood. Other territories administered by the United States went on to become independent countries, such as the Philippines, Micronesia, Marshall Islands and Palau. Micronesia, Marshall Islands and Palau gained independence under the Compact of Free Association (COFA), which allows the U.S. full authority over aid and defense in exchange for continued access to U.S. health care, government services such as the FCC and United States Postal Service, and the right for COFA citizens to work freely in the United States and vice versa.
Many organized incorporated territories of the United States existed from 1789 to 1959 (the first being the Northwest and the Southwest territories, the last being the Alaska Territory and the Hawaii Territory), through which 31 territories applied for and were granted statehood. In the process of organizing and promoting territories to statehood, some areas of a territory demographically lacking sufficient development and population densities were temporarily orphaned from parts of a larger territory at the time a vote was taken petitioning Congress for statehood rights. For example, when a portion of the Missouri Territory became the state of Missouri, the remaining portion of the territory, consisting of the present states of Iowa, Nebraska and the Dakotas, most of Kansas, Wyoming, and Montana, and parts of Colorado and Minnesota, effectively became an unorganized territory.

Currently, there are a total of sixteen territories of the United States, five of which are inhabited: Puerto Rico, Guam, Northern Marianas, United States Virgin Islands and American Samoa. The 11 uninhabited territories administered by the Interior Department are Palmyra Atoll, Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, and Midway Islands. While claimed by the US, Navassa Island, Wake Island, Serranilla Bank and Bajo Nuevo Bank are disputed.
Territories have always been a part of the United States. By Act of Congress, the term ‘United States’, when used in a geographical sense, means “the continental United States, Alaska, Hawaii, Puerto Rico, Guam, and the Virgin Islands of the United States”. Since political union with the Northern Mariana Islands in 1986, they too are treated as a part of the U.S. An Executive Order in 2007 includes American Samoa as U.S. “geographical extent” duly reflected in U.S. State Department documents.
Inhabited United States territories have democratic self-government, in local three-branch governments, found respectively in Pago Pago, American Samoa; Hagåtña, Territory of Guam; Saipan, Commonwealth of the Northern Mariana Islands; San Juan, Commonwealth of Puerto Rico; Charlotte Amalie, United States Virgin Islands.
Approximately 4 million islanders are U.S. citizens; about 32,000 U.S. non-citizen nationals live in American Samoa. Under current law among the territories, "only persons born in American Samoa and Swains Island are non-citizen U.S. nationals." American Samoans are under the protection of the U.S., with freedom of U.S. travel without visas.
The five inhabited U.S. territories have local voting rights and protections under U.S. courts, pay some U.S. taxes, and have limited representation in the U.S. House of Representatives. They popularly elect “Members of Congress” who, like the delegate from DC, “possess the same powers as other members of the House, except that they may not vote when the House is meeting as the House of Representatives.” They participate in debate, are assigned offices and money for staff, and appoint constituents from their territories to the Army, Navy, Air Force, Coast Guard, and Merchant Marine service academies. They can vote in committee on all legislation presented to the House of Representatives, they are included in their party count for each committee, and they are equal to senators on conference committees. Depending on the congress, they may also vote on the floor in the House Committee of the Whole.
Members of Congress from the territories seated as of January 2015 are Gregorio Sablan for the Northern Mariana Islands, Madeleine Bordallo for Guam, Amata Coleman Radewagen for American Samoa, Pedro Pierluisi for Puerto Rico, and Stacey Plaskett for the U.S. Virgin Islands.
Every four years, the Democratic and Republican political parties nominate their presidential candidates at conventions which include delegates from the five major territories. The citizens there, however, do not vote in the general election for U.S. President.
Incorporated and unincorporated territories
An incorporated territory of the United States is a specific area under the jurisdiction of the United States, over which the United States Congress has determined that the United States Constitution is to be applied to the territory's local government and inhabitants in its entirety (e.g., citizenship, trial by jury), in the same manner as it applies to the local governments and residents of the U.S. states. Incorporated territories are considered an integral part of the United States, as opposed to being merely possessions.
All territory under the control of the federal government is considered part of the "United States" for purposes of law. From 1901 to 1905, the U.S. Supreme Court in a series of opinions known as the Insular Cases held that the Constitution extended ex proprio vigore (by its own force) to the territories. However, the Court in these cases also established the doctrine of territorial incorporation, under which the Constitution applies fully only in incorporated territories such as the then Territory of Alaska and Territory of Hawaii, and applies only partially in the new unincorporated territories of Puerto Rico, Guam and the Philippines.
To define what is an unincorporated territory in Balzac v. People of Porto Rico, 258 U.S. 298, 312 (1922), the Court used, as an argument of non-incorporated territory, the following statement regarded the U.S. court in Puerto Rico:
The United States District Court is not a true United States court established under article 3 of the Constitution to administer the judicial power of the United States therein conveyed. It is created by virtue of the sovereign congressional faculty, granted under article 4, 3, of that instrument, of making all needful rules and regulations respecting the territory belonging to the United States. The resemblance of its jurisdiction to that of true United States courts, in offering an opportunity to nonresidents of resorting to a tribunal not subject to local influence, does not change its character as a mere territorial court.
Upon like considerations, Article III has been viewed as inapplicable to courts created in unincorporated territories outside the mainland, Downes v. Bidwell, 182 U.S. 244, 266 -267; Balzac v. Porto Rico, 258 U.S. 298, 312 -313; cf. Dorr v. United States, 195 U.S. 138, 145 , 149, and to the consular courts established by concessions from foreign countries, In re Ross, 140 U.S. 453, 464 -465, 480. 18
The U.S. Supreme Court offers two ways in which incorporation could be made: "incorporation is not to be assumed without express declaration, or an implication so strong as to exclude any other view."
Express or implied?
In Balzac, where Chief Justice Taft delivered the opinion of the Court, the meaning of implied was specified:
Had Congress intended to take the important step of changing the treaty status of Puerto Rico by incorporating it into the Union, it is reasonable to suppose that it would have done so by the plain declaration, and would not have left it to mere inference. Before the question became acute at the close of the Spanish War, the distinction between acquisition and incorporation was not regarded as important, or at least it was not fully understood and had not aroused great controversy. Before that, the purpose of Congress might well be a matter of mere inference from various legislative acts; but in these latter days, incorporation is not to be assumed without express declaration, or an implication so strong as to exclude any other view.
Incorporated territories U.S. Supreme Court declarations
In Rassmussen v. U S, 197 U.S. 516 (1905), quoting from Article III of the 1867 treaty for the purchase of Alaska, the Supreme Court said, "'The inhabitants of the ceded territory ... shall be admitted to the enjoyment of all the rights, advantages, and immunities of citizens of the United States; ...'. This declaration, although somewhat changed in phraseology, is the equivalent, as pointed out in Downes v. Bidwell, of the formula, employed from the beginning to express the purpose to incorporate acquired territory into the United States, especially in the absence of other provisions showing an intention to the contrary." Here we see that the act of incorporation is on the people of the territory, not on the territory per se, by extending the privileges and immunities clause of the Constitution to them. The U.S. Supreme Court statements follow:
Congress express declaration:
Rassmussen v. the United States (197 U.S. 516, 522 (1905)) arose out of a misdemeanor conviction in Alaska by a jury composed of six persons pursuant to a federal statute allowing such a procedure in Alaska. In a decision written by Justice White, a majority of the Court concluded that Alaska had been incorporated into the United States because the treaty of cession with Russia specifically declared that "the inhabitants of the ceded territory shall be admitted to the enjoyment of all the rights, advantages and immunities of citizens of the United States.
In addition, there was Congressional implication so strong as to exclude any other view:
That Congress, shortly following the adoption of the treaty with Russia, clearly contemplated the incorporation of Alaska into the United States as a part thereof, we think plainly results from the act of July 20, 1868, concerning internal revenue taxation, chap. 186, 107 (15 Stat. at L. 167, U. S. Comp. Stat. 1901, p. 2277), and the act of July 27, 1868, chap. 273, extending the laws of the United States relating to customs, commerce, and navigation over Alaska, and establishing a collection district therein. 15 Stat. at L. 240. And this is fortified by subsequent action of Congress, which it is unnecessary to refer to.— Rassmussen at 533–534
Justice Brown, in his concurring opinion, also expressed the same thought:
Apparently, acceptance of the territory is insufficient in the opinion of the court in this case, since the result that Alaska is incorporated into the United States is reached, not through the treaty with Russia, or through the establishment of a civil government there, but from the act of July 20, 1868, concerning internal revenue taxation, and the act of July 27, 1868, extending the laws of the United States relating to the customs, commerce, and navigation over Alaska, and establishing a collection district there. Certain other acts are cited, notably the judiciary act of March 3, 1891, making it the duty of this court to assign [197 U.S. 516, 534] the several territories of the United States to particular Circuits.
In Dorr v. USA (195 U.S. 138, 141–142 (1904)) Justice Marshall is quoted more extensively as follows:
The 6th article of the treaty of cession contains the following provision:
The inhabitants of the territories which His Catholic Majesty cedes the United States by this treaty shall be incorporated in the Union of the United States as soon as may be consistent with the principles of the Federal Constitution, and admitted to the enjoyment of the privileges, rights, and immunities of the citizens of the United States. [8 Stat. at L. 256.] [195 U.S. 138, 142] 'This treaty is the law of the land, and admits the inhabitants of Florida to the enjoyment of the privileges, rights, and immunities of the citizens of the United States. It is unnecessary to inquire whether this is not their condition, independent of stipulation. They do not, however, participate in political power; they do not share in the government till Florida shall become a state. In the meantime Florida continues to be a territory of the United States, governed by virtue of that clause in the Constitution which empowers Congress 'to make all needful rules and regulations respecting the territory or other property belonging to the United States." 
In Downes v. Bidwell, 182 U.S. 244, 256 (1901), Justice Brown says:
The same construction was adhered to in the treaty with Spain for the purchase of Florida (8 Stat. at L. 252) the 6th article of which provided that the inhabitants should 'be incorporated into the Union of the United States, as soon as may be consistent with the principles of the Federal Constitution;
In Downes v. Bidwell supra at 321–322, the first mention of incorporation is made in the following paragraph by Justice Brown:
In view of this it cannot, it seems to me, be doubted that the United States continued to be composed of states and territories, all forming an integral part thereof and incorporated therein, as was the case prior to the adoption of the Constitution. Subsequently, the territory now embraced in the state of Tennessee was ceded to the United States by the state of North Carolina. In order to insure the rights of the native inhabitants, it was expressly stipulated that the inhabitants of the ceded territory should enjoy all the rights, privileges, benefits, and advantages set forth in the ordinance 'of the late Congress for the government of the western territory of the United States.
In Downes v. Bidwell supra at 252, it was said:
Owing to a new war between England and France being upon the point of breaking out, there was need for haste in the negotiations, and Mr. Livingston took the responsibility of disobeying his (Mr. Jefferson's) instructions, and, probably owing to the insistence of Bonaparte, consented to the 3d article of the treaty (with France to acquire the territory of Louisiana), which provided that 'the inhabitants of the ceded territory shall be incorporated in the Union of the United States, and admitted as soon as possible, according to the principles of the Federal Constitution, to the enjoyment of all the rights, advantages, and immunities of citizens of the United States; and in the meantime they shall be maintained and protected in the free enjoyment of their liberty, property, and the religion which they profess.' [8 Stat. at L. 202.] This evidently committed the government to the ultimate, but not to the immediate, admission of Louisiana as a state, ...
The Supreme Court of the United States is unanimous in its interpretation that the extension of the privileges and immunities clause of the Constitution of the United States to the inhabitants of a territory in effect produces the incorporation of that territory. The net effect of incorporation is that the territory becomes an integral part of the geographical boundaries of the United States and cannot, from then on, be separated. Indeed, the whole body of the U.S. Constitution is extended to the inhabitants of that territory, except for those provisions that relate to its federal character.
More so, the needful rules and regulations of the territorial clause must yield to the Constitution and the inherent constraints imposed on it in dealing with the privileges and immunites of the inhabitants of the incorporated territory. Notice must be taken that incorporation of a territory takes place through the incorporation of its inhabitants, not of the territory per se. As such, those inhabitants receive the full impact of the U.S. Constitution, except for those provisions that deal specifically with the federal character of the Union.
In the contemporary sense, the term "unincorporated territory" refers primarily to insular areas. There is currently only one incorporated territory, Palmyra Atoll, which is not an organized territory. Conversely, a territory can be organized without being an incorporated territory, a contemporary example being Puerto Rico.
Lands under the sovereignty of the federal government (but not part of any state) that were given a measure of self-rule by the Congress through an Organic Act subject to the Congress’ plenary powers under the territorial clause of Article IV, sec. 3, of the U.S. Constitution.
Classification of current U.S. territories
Incorporated organized territories
No incorporated organized territories have existed since 1959, the last two being the Territory of Hawaii and Territory of Alaska, both of which achieved statehood in that year, with their representative stars being added in the blue field/canton of the American flag on Independence Day, July 4, in 1959 and 1960, respectively.
Incorporated unorganized territories
Many incorporated unorganized territories became incorporated organized territories or states. For example, when the eastern part of the incorporated organized territory called Minnesota became the state of Minnesota in 1858, the western part became part of an unorganized territory. Later that became a part of the Dakota Territory, out of which two states and some parts of other states were created. California was part of an unorganized territory when it became a state.
|Palmyra Atoll||Polynesia & North Pacific||12 km2 (5 sq mi)||0||As of 2007, partly privately owned by The Nature Conservancy with much of the rest owned by the federal government and managed by the U.S. Fish and Wildlife Service. It is an archipelago of about 50 small islands with about 1.56 sq mi (4 km2) of land area, lying about 1,000 miles (1,609 km) south of Oahu, Hawaii. The atoll was acquired by the United States through the annexation of the Republic of Hawaii in 1898. When the Territory of Hawaii was incorporated on April 30, 1900, Palmyra Atoll was incorporated as part of that territory. However, when the State of Hawaii was admitted to the Union in 1959, the Act of Congress explicitly separated Palmyra Atoll from the newly federated state. Palmyra remained an incorporated territory, but received no new organized government.|
There are also "territories" that have the status of being incorporated but that are not organized:
- U.S. coastal waters out to 12 nautical miles (22.2 km) offshore (except state waters extend a minimum of 3 nautical miles (5.6 km) offshore).
- U.S. flagged vessels at sea, including the Navy, Coast Guard, and Merchant Marine.
Unincorporated organized territories
|Guam||Micronesia & North Pacific||543 km2 (210 sq mi)||159,358||Hagåtña||Territory since 1898, Guam is the home of Naval Base Guam and Andersen Air Force Base.|
|Northern Mariana Islands||Micronesia & North Pacific||463.63 km2 (179 sq mi)||77,000||Saipan||Commonwealth since 1978; formerly a United Nations Trust Territory under the administration of the U.S.|
|Puerto Rico||Caribbean & North Atlantic||9,104 km2 (3,515 sq mi)||3,667,084||San Juan||Unincorporated territory since 1898, a commonwealth since 1952. In November 2008, a U.S. District Court judge ruled that a sequence of Congressional actions have had the cumulative effect of changing Puerto Rico's status from "unincorporated" to "incorporated." However, the issue has not finished making its way through the court system; and the U.S. government still refers to Puerto Rico as unincorporated. See the Puerto Rico section in the article, Organized incorporated territories of the United States, and also the article, Political status of Puerto Rico.|
|United States Virgin Islands||Caribbean & North Atlantic||346.36 km2 (134 sq mi)||106,405||Charlotte Amalie||Purchased by the U.S. from Denmark in 1917.|
Unincorporated unorganized territories

|Midway Islands||North Pacific||6.2 km2 (2 sq mi)||0||Territory since 1859; primarily a wildlife refuge inhabited only by civilian contractors; previously under the jurisdiction of the Department of the Navy.|
|Navassa Island||Caribbean & North Atlantic||5.4 km2 (2 sq mi)||0||Territory since 1857. Claimed by Haiti.|
|Serranilla Bank||Caribbean & North Atlantic||350 km2 (135 sq mi)||0||Administered by Colombia; site of a naval garrison. Claimed by the United States (since 1879 under the Guano Islands Act) and Honduras. A claim by Nicaragua was resolved in 2012 in favor of Colombia by the International Court of Justice.|
|Bajo Nuevo Bank||Caribbean & North Atlantic||110 km2 (42 sq mi)||0||Administered by Colombia. Claimed by the United States (under the Guano Islands Act), Jamaica, and Nicaragua|
The United States exercises some degree of extraterritorial jurisdiction in overseas areas such as:
- Guantanamo Bay Naval Base (since 1903): A 45 sq mi (117 km2) area of land along Guantánamo Bay, Cuba, to which the United States claims to hold a perpetual lease; This Cuban government does not recognize America's claim, and has refused to accept any payment since 1959. The actual lease amount is just US$2,000 in gold per year (equivalent in value in 2004 to approximately US$4,000).
- American Research stations in Antarctica: Amundsen–Scott South Pole Station, McMurdo Station, Palmer Station are under American jurisdiction, but held without sovereignty as per the Antarctic Treaty.
- Certain other parcels in foreign countries held by lease, such as military bases, depending on the terms of a lease, treaty, or status of forces agreement with the host country.
The United States exercises a high degree of control in defense, funding, and government services in:
