Puerto Rico Compared to Other U.S. Territories: Guam, USVI, and American Samoa

The four principal unincorporated territories of the United States — Puerto Rico, Guam, the U.S. Virgin Islands, and American Samoa — share a foundational legal category but differ substantially in population size, constitutional standing, citizenship status, and federal relationship. Understanding these distinctions is essential for legal practitioners, policy analysts, and researchers navigating territorial governance, federal funding structures, and political status questions. The Puerto Rico Territory Authority provides reference-grade coverage of the Puerto Rico dimension of this comparative landscape.

Definition and Scope

All four territories occupy the status of unincorporated territories under U.S. jurisdiction, a category established through Supreme Court precedent in the Insular Cases beginning in 1901. Under the Territorial Clause of the U.S. Constitution (Article IV, Section 3, Clause 2), Congress holds plenary authority over these jurisdictions. None is a state, and none has full congressional representation.

The scope of comparison covers four distinct variables across the four territories:

  1. Population and demographic scale — Puerto Rico, with approximately 3.2 million residents (U.S. Census Bureau, 2020 Decennial Census), dwarfs Guam (~153,000), the U.S. Virgin Islands (~87,000), and American Samoa (~55,000) by orders of magnitude.
  2. Citizenship status — Puerto Ricans and residents of Guam and the USVI hold U.S. citizenship by statute; American Samoans hold U.S. nationality but not citizenship, a distinction that the U.S. Court of Appeals for the Tenth Circuit addressed in Fitisemanu v. United States (2021).
  3. Constitutional rights applicability — The degree to which the Bill of Rights applies in each territory is governed by the incorporated vs. unincorporated territories framework, with fundamental rights applying and non-fundamental rights potentially excluded.
  4. Local governance structure — Each territory operates under a distinct organic act or constitution, with varying degrees of self-governance.

How It Works

The federal relationship with each territory is mediated through specific enabling legislation and administrative frameworks.

Puerto Rico operates under a constitution ratified in 1952, granting substantial self-governance as a commonwealth, though PROMESA (Public Law 114-187, enacted 2016) installed a federal Fiscal Oversight and Management Board that supersedes certain local legislative authority over fiscal matters.

Guam is governed under the Organic Act of Guam (1950), which conferred U.S. citizenship on Guamanians. Guam's legislature has 15 members and the territory elects a non-voting delegate to the U.S. House of Representatives, the same arrangement Puerto Rico has through its Resident Commissioner.

The U.S. Virgin Islands was purchased from Denmark in 1917 for $25 million (U.S. Department of State Office of the Historian). Its residents received citizenship via the Revised Organic Act of 1954. The USVI operates a unicameral 15-member legislature and holds no Electoral College votes, identical to Puerto Rico.

American Samoa holds the most restricted federal relationship. Its residents are U.S. nationals — not citizens — meaning they cannot vote in federal elections upon relocating to states unless they pursue naturalization. The territory is governed under the American Samoa Revised Constitution of 1967, the only territorial constitution not congressionally enacted but locally drafted.

Common Scenarios

Comparative territorial analysis arises in four recurring professional and policy contexts:

  1. Federal benefit eligibility — Puerto Rico's federal funding disparities in Medicaid, Supplemental Security Income (SSI), and Supplemental Nutrition Assistance Program (SNAP) mirror structural inequities that also affect Guam and the USVI, though the specific caps and matching rates differ per program authorization.
  2. Military service obligations — Residents of Puerto Rico, Guam, and the USVI are subject to the military draft and serve in the U.S. Armed Forces. American Samoans serve as well, despite their non-citizen status; the history of Puerto Rican military service is a particularly documented dimension of this pattern.
  3. Political status referendums — Puerto Rico has held 6 status referendums between 1967 and 2020 (Puerto Rico State Elections Commission). Guam has conducted its own self-determination plebiscites, while the USVI and American Samoa have not pursued equivalent formal referendum processes.
  4. Tax jurisdiction — Puerto Rico's Act 60 tax incentive regime is specific to the commonwealth. Guam, the USVI, and American Samoa each operate separate tax mirror codes or independent tax systems under distinct federal authorizations.

Decision Boundaries

The critical distinctions that determine legal and administrative outcomes across these territories fall along 3 axes:

Citizenship vs. nationality: The American Samoa distinction is operationally significant. A U.S. national cannot hold federal civil service positions requiring citizenship, cannot serve on federal juries, and faces naturalization requirements to obtain a U.S. passport confirming citizenship rather than nationality.

Degree of fiscal autonomy: Puerto Rico's PROMESA oversight board structure has no direct equivalent in Guam, the USVI, or American Samoa. While all four territories receive federal grants and appropriations, only Puerto Rico has a congressionally imposed fiscal control board with override authority over local legislation.

Population-weighted political leverage: Puerto Rico's population of approximately 3.2 million exceeds the combined populations of Guam, the USVI, and American Samoa by a factor exceeding 12. This scale differentiates Puerto Rico's statehood and status debates — covered in depth at the Puerto Rico Government Authority, a reference resource documenting the structure and function of Puerto Rico's governmental institutions — from those of the smaller territories, both in congressional attention and in the practical implications of any status resolution.
