Current status

All of the five major U.S. territories are permanently inhabited and have locally elected territorial legislatures and executives and some degree of political autonomy. Four of the five are "organized", but American Samoa is technically "unorganized". All of the U.S. territories without permanent non-military populations are unorganized.

coordinates federal administration of the U.S. territories and freely associated states, except for Puerto Rico. 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 administered by the Office of Insular Affairs.

In 2020, their combined population was about 3.62 million, over 90% of which is accounted for by Puerto Rico alone. People born in Puerto Rico, the U.S. Virgin Islands, Guam and the Northern Mariana Islands acquire U.S. citizenship by birth, and foreign nationals residing there may apply for U.S. citizenship by naturalization. People born in American Samoa acquire U.S. nationality but not U.S. citizenship by birth if they do not have a U.S. citizen parent. U.S. nationals without U.S. citizenship may hold U.S. passports and reside in any part of the United States without restriction. However, to become U.S. citizens they must apply for naturalization, like foreigners, and may only do so while residing in parts of the United States other than American Samoa. Foreign nationals residing in American Samoa cannot apply for U.S. citizenship or U.S. nationality at all.

In the decision, the court explained that the exemption of island residents from most federal income taxes provides a "rational basis" for their exclusion from eligibility for SSI payments. American Samoa is the only U.S. territory with its own immigration system (a system separate from the United States immigration system). American Samoa also has a communal land system in which ninety percent of the land is communally owned; ownership is based on Samoan ancestry.

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.

Of the five major territories, only Puerto Rico has an Article III federal district court (i.e., equivalent to the courts in the fifty states); it became an Article III court in 1966. This means that, unlike other U.S. territories, federal judges in Puerto Rico have life tenure. Federal courts in Guam, the Northern Mariana Islands and the U.S. Virgin Islands are Article IV territorial courts. The following is a list of federal territorial courts, plus Puerto Rico's court: * District Court of Guam ( Ninth Circuit) *
District Court for the Northern Mariana Islands The District Court for the Northern Mariana Islands (in case citations, D. N. Mar. I.) is a federal territorial court whose jurisdiction comprises the United States-affiliated Commonwealth of the Northern Mariana Islands (CNMI). It was establi ...

. 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, one of the justices opined that it was time to overrule the incorporation doctrine, as wrongly decided and founded in racism.

The U.S. had no 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

which ended the Spanish–American War. The Supreme Court considered the constitutional position of these unincorporated territories in 1922 in '' Balzac v. People of Porto Rico'', and said the following about a U.S. court in Puerto Rico: In '' 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

urged the Supreme Court to overrule the Insular Cases when possible as it "rests on rotten foundation" and called the cases "shameful". In analyzing the Insular Cases, Christina Duffy Ponsa of the New York Times said the following: "To be an unincorporated territory is to be caught in limbo: although unquestionably subject to American sovereignty, they are not 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."

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 the treaty of cession with Russia, and the congressional implication was strong enough to exclude any other view: Concurring justice 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'."

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. The United States Supreme Court, in 2021, 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 that are different from the states, but did not address the incorporated/unincorporated distinction. In a concurrence, one of the justices opined that it was time to overrule the Insular Cases and the incorporation doctrine, as wrongly decided.

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, osenators, 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 he U.S. territoriesare 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 oward territoriesat the time of Pearl Harbor hasn't changed much at all. .. aps of the contiguous U.S.give ainlandersa truncated view of their own history, one that excludes part of their country." The 2020 U.S. Census excludes non-citizen U.S. nationals in American Samoa—in response to this, Mark Stern of Slate.com 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."
