Since 1917, Puerto Ricans have been granted U.S. citizenship. Puerto Rico was organized under the Puerto Rico Federal Relations Act of 1950 (Public Law 600). In November 2008, a U.S. District Court judge ruled that a series of Congressional actions have had the cumulative effect of changing Puerto Rico's status from unincorporated to incorporated. The issue is proceeding through the courts, however, and the U.S. government still refers to Puerto Rico as unincorporated. A Puerto Rican attorney has called the island "semi-sovereign".

For statistical purposes, the U.S. Census Bureau has a defined area called the "Island Areas" which consists of American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands (every major territory except Puerto Rico). The U.S. Census Bureau often treats Puerto Rico as its own entity or groups it with the states and D.C. (for example, Puerto Rico has a QuickFacts page just like the states and D.C.) Puerto Rico data is collected annually in American Community Survey estimates (just like the states), but data for the other territories is collected only once every ten years.

Claimed territories

The following two territories are claimed by multiple countries (including the United States) and are not included in ISO 3166-2:UM. However, they are sometimes grouped with the U.S. Minor Outlying Islands. According to the GAO, "the United States conducts maritime law enforcement operations in and around Serranilla Bank and Bajo Nuevo [Bank] consistent with U.S. sovereignty claims."


Incorporated vs. unincorporated territories

Pursuant to a series of Supreme Court rulings, Congress decides whether a territory is incorporated or unincorporated. The Constitution of the United States, U.S. Constitution applies to each incorporated territory (including its local government and inhabitants) as it applies to the local governments and residents of a state. The singular incorporated territory (also known as a ''Territory'', distinct from ''territory'') of the U.S., Palmyra Atoll, is an insular part of the U.S. (neither a part of one of the several States nor a Federal district), but is not a possession. In unincorporated territories, "fundamental rights apply as a matter of law, but other constitutional rights are not available", raising concerns about how citizens in these territories can influence Politics of the United States, politics in the United States. Selected constitutional provisions apply, depending on congressional acts and judicial rulings according to U.S. constitutional practice, local tradition, and law. As a result, these territories are often considered colonies of the United States. All modern inhabited territories under the control of the federal government can be considered as part of the "United States" for purposes of law as defined in specific legislation. However, the judicial term "unincorporated" was coined to legitimize the late-19th-century territorial acquisitions without citizenship and their administration without constitutional protections temporarily until Congress made other provisions. The case law allowed Congress to impose discriminatory tax regimes with the effect of a protective tariff upon territorial regions which were not domestic states. In 2022, the United States Supreme Court in ''United States v. Vaello Madero'' held that the territorial clause of the constitution allowed wide congressional latitude in mandating "reasonable" tax and benefit schemes in Puerto Rico and the other territories, which are different from the states, but did not address the incorporated/unincorporated distinction. In a concurrence with the court's overall ruling on the propriety of the differential tax structures, one of the justices opined that it was time to overrule the doctrine of unincorporated territories, as wrongly decided and founded in racism; the dissent agreed with this view.

, and, at the time, the Philippines (which is no longer a U.S. territory). In the 1901 Supreme Court case ''Downes v. Bidwell'', the Court said that the U.S. Constitution did not fully apply in unincorporated territories because they were inhabited by "alien races". The U.S. had no unincorporated territories of the United States, unincorporated territories (also known as overseas possessions or insular areas) until 1856. Congress enacted the Guano Islands Act that year, authorizing the president to take possession of unclaimed islands to mine guano. The U.S. has taken control of (and claimed rights on) many islands and atolls, especially in the Caribbean Sea and the Pacific Ocean, under this law; most have been abandoned. It also has acquired territories since 1856 under other circumstances, such as under the Treaty of Paris (1898) which ended the Spanish–American War. The Supreme Court considered the constitutional position of these unincorporated territories in 1922 in ''Balzac v. Porto Rico, Balzac v. People of Porto Rico'', and said the following about a U.S. court in Puerto Rico: In ''Glidden Co. v. Zdanok, Glidden Company v. Zdanok'', the Court cited ''Balzac'' and said about courts in unincorporated territories: "Upon like considerations, Article III has been viewed as inapplicable to courts created in unincorporated territories outside the mainland... and to the consular courts established by concessions from foreign countries". The judiciary determined that incorporation involves express declaration or an implication strong enough to exclude any other view, raising questions about Puerto Rico's status. In 1966, Congress made the United States District Court for the District of Puerto Rico an Article Three of the United States Constitution, Article III United States district court, district court. This (the only district court in a U.S. territory) sets Puerto Rico apart judicially from the other unincorporated territories, and U.S. district judge Gustavo Gelpí has expressed the opinion that Puerto Rico is no longer unincorporated: In ''Balzac'', the Court defined "implied": On June 5, 2015, the U.S. Court of Appeals for the District of Columbia ruled 3–0 in ''Tuaua v. United States'' to deny Birthright citizenship in the United States, birthright citizenship to American Samoans, ruling that the guarantee of such citizenship to citizens in the Fourteenth Amendment does not apply to unincorporated U.S. territories. In 2016 the U.S. Supreme Court declined to review the appellate court's decision. In 2018, the United States Court of Appeals for the 7th Circuit upheld the District Court decision in ''Segovia v. United States'', which ruled that former Illinois residents living in Puerto Rico, Guam, and the U.S. Virgin Islands did not qualify to cast overseas ballots according to their last registered address on the U.S. mainland. (Residents of the Northern Mariana Islands, Northern Marianas and
American Samoa American Samoa is an Territories of the United States, unincorporated and unorganized territory of the United States located in the Polynesia region of the Pacific Ocean, South Pacific Ocean. Centered on , it is southeast of the island count ...
, however, were still allowed to cast such ballots.) In October 2018, the U.S. Supreme Court declined to review the 7th Circuit's decision. On June 15, 2021, the United States Court of Appeals for the Tenth Circuit ruled 2–1 in ''Fitisemanu v. United States'' to deny birthright citizenship to American Samoans and not to overrule the Insular Cases. The court cited Downes and ruled that "neither constitutional text nor Supreme Court precedent" demands that American Samoans should be given automatic birthright citizenship. The case was denied certiorari by the U.S. Supreme Court. On April 21, 2022, in the case ''United States v. Vaello Madero'', Neil Gorsuch, Justice Gorsuch urged the Supreme Court to overrule the Insular Cases when possible as they "rest on a rotten foundation" and called the cases "shameful". In analyzing the Insular Cases, Christina Duffy Ponsa (Juris Doctor, Yale Law School, 1998; former law clerk for Justice Stephen Breyer) wrote in ''The New York Times'': "To be an unincorporated territory is to be caught in limbo: although unquestionably subject to American sovereignty, they are considered part of the United States for certain purposes but not others. Whether they are part of the United States for purposes of the Citizenship Clause remains unresolved. "


Supreme Court decisions about current territories

The 2016 Supreme Court case ''Puerto Rico v. Sanchez Valle'' ruled that territories do not have their own sovereignty. That year, the Supreme Court declined to rule on a lower-court ruling in ''Tuaua v. United States'' that American Samoans are not U.S. citizens at birth. The Supreme Court ruled in 2022 in ''United States v. Vaello-Madero'' that Congress is not required to extend all benefits to Puerto Ricans, and that the exclusion of Puerto Ricans from the Supplemental Security Income program was constitutional.


Supreme Court decisions about former territories

In ''Rassmussen v. U.S.'', the Supreme Court quoted from Article III of the 1867 treaty for the purchase of Alaska: The act of incorporation affects the people of the territory more than the territory itself by extending the Privileges and Immunities Clause of the Constitution to them, such as its extension to Puerto Rico in 1947; however, Puerto Rico remains unincorporated.


Alaska Territory

''Rassmussen'' arose from a criminal conviction by a six-person jury in Alaska under federal law. The court held that Alaska had been incorporated into the U.S. in Alaska Purchase, the treaty of cession with Russia, and the congressional implication was strong enough to exclude any other view: Concurring justice Henry Billings Brown, Henry Brown agreed:


Florida Territory

In ''Dorr v. U.S.'', the court quoted Chief Justice John Marshall from an earlier case: In ''Downes v. Bidwell'', the court said: "The same construction was adhered to in the treaty with Spain for the purchase of Florida... 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'."


Southwest Territory

Justice Brown first mentioned incorporation in ''Downes'':


Louisiana Territory

In ''Downes'', the court said:


Modern Puerto Rico

Scholars agreed as of 2009 in the ''Boston College Law Review'', "Regardless of how Puerto Rico looked in 1901 when the Insular Cases were decided, or in 1922, today, Puerto Rico seems to be the paradigm of an incorporated territory as modern jurisprudence understands that legal term of art". In November 2008, a district court judge ruled that a sequence of prior Congressional actions had the cumulative effect of changing Puerto Rico's status to incorporated. However, in 2022, the United States Supreme Court United States v. Vaello Madero, held that the territorial clause of the U.S. constitution allows wide congressional latitude in mandating "reasonable" tax and benefit schemes in Puerto Rico and the other territories that are different from the states, but the Court did not address the incorporated/unincorporated distinction. As a result, the ''status quo'' remains, so the U.S. government still defines the Commonwealth of Puerto Rico as a U.S. unincorporated territory.

In ''The Not-Quite States of America'', his book about the U.S. territories, essayist Doug Mack said: Representative Stephanie Murphy of Florida said about a 2018 bill to make Puerto Rico the 51st state, "The hard truth is that Puerto Rico's lack of political power allows Washington to treat Puerto Rico like an afterthought." According to Governor of Puerto Rico Ricardo Rosselló, "Because we don't have political power, because we don't have representatives, [no] senators, no vote for president, we are treated as an afterthought." Rosselló called Puerto Rico the "oldest, most populous colony in the world". Rosselló and others have referred to the U.S. territories as American "colonies". David Vine of ''The Washington Post'' said the following: "The people of [the U.S. territories] are all too accustomed to being forgotten except in times of crisis. But being forgotten is not the worst of their problems. They are trapped in a state of third-class citizenship, unable to access full democratic rights because politicians have long favored the military's freedom of operation over protecting the freedoms of certain U.S. citizens." In his article "How the U.S. Has Hidden Its Empire", Daniel Immerwahr of ''The Guardian'' writes, "The confusion and shoulder-shrugging indifference that mainlanders displayed [toward territories] at the time of Pearl Harbor hasn't changed much at all. [...] [Maps of the contiguous U.S.] give [mainlanders] a truncated view of their own history, one that excludes part of their country." The 2020 United States census, 2020 U.S. Census excludes non-citizen U.S. nationals in American Samoa—in response to this, Mark Joseph Stern of ''Slate'' said, "The Census Bureau's total exclusion of American Samoans provides a pertinent reminder that, until the courts step in, the federal government will continue to treat these Americans with startling indifference."
