When people think of the United States, they picture fifty states spanning from Maine to Hawaii. But the nation's full political footprint extends far beyond those borders. The United States includes five major inhabited territories and several smaller, uninhabited island possessions scattered across the Caribbean Sea and the Pacific Ocean. None of these territories are independent countries, yet they maintain unique legal, political, and cultural relationships with Washington.
Strictly speaking, no foreign countries are included inside the USA. Instead, the country's sovereign jurisdiction encompasses the 50 individual states, the federal district of Washington, D.C., and 14 overseas insular areas administered under various forms of American governance. Understanding this makeup requires looking closely at how these territories function, who lives there, and how they differ from standard states.
The 50 States and the Federal District
The core of the United States consists of 50 sovereign states joined under a federal republic, alongside the Capital district. While each state operates its own government and shares sovereignty with the federal government, they form a unified national entity.
The federal district—Washington, D.C.—isn't part of any state. It functions under the exclusive jurisdiction of the United States Congress, though local residents elect a mayor and a city council to handle municipal affairs. Beyond these domestic borders, the nation governs distant island regions acquired through various treaties, purchases, and historical acts during the 19th and 20th centuries.
The Five Inhabited U.S. Territories
While 14 total territories exist under U.S. control, only five are permanently populated by American citizens and nationals. These regions feature local legislatures, governors, and distinct cultural identities rooted in their geographic locations.
Puerto Rico
Located in the northeast Caribbean Sea, Puerto Rico is an unincorporated, organized commonwealth. It was acquired from Spain in 1899 following the Spanish-American War. Puerto Ricans have been statutory U.S. citizens since 1917, use U.S. currency, and are subject to federal laws, though they don't pay federal personal income taxes on local income. The island's political status remains a frequent topic of debate, with residents periodically voting on whether to pursue statehood, independence, or enhanced sovereignty.
Guam
Guam is the southernmost and largest island in the Mariana archipelago, situated in the Western Pacific. Also acquired from Spain in 1899, Guam functions as an unincorporated and organized territory. It holds major strategic importance as a hub for the United States Armed Forces, hosting significant Air Force and Navy installations. Residents are U.S. citizens, but they lack voting representation in Congress and cannot cast ballots in presidential elections while residing on the island.
United States Virgin Islands
Situated in the Caribbean just east of Puerto Rico, the U.S. Virgin Islands comprise St. Croix, St. Thomas, St. John, and dozens of smaller cays. The United States purchased the islands from Denmark in 1917 during World War I to protect maritime shipping lanes. Residents are U.S. citizens, vote in local elections, and elect a non-voting delegate to the House of Representatives, operating under an organized, unincorporated framework.
American Samoa
American Samoa is a collection of islands in the South Pacific Ocean, roughly halfway between Hawaii and New Zealand. It is unique among the inhabited territories because it's classified as unorganized, meaning Congress hasn't passed an organic act establishing a formal local constitution drafted by federal statute. Instead, the territory operates under its own constitution ratified locally. People born in American Samoa are U.S. nationals rather than automatic U.S. citizens, though many choose to naturalize.
Northern Mariana Islands
The Commonwealth of the Northern Mariana Islands (CNMI) is a chain of 14 islands in the Pacific Ocean. After decades of administration under a United Nations trusteeship following World War II, the islands entered a covenant of political union with the United States in 1976. Residents are U.S. citizens, and the territory functions as a self-governing commonwealth in political union with the federal government.
Uninhabited U.S. Minor Outlying Islands
In addition to the five populated regions, the United States claims sovereignty over several remote, mostly uninhabited islands and atolls. These are managed directly by federal agencies, primarily the U.S. Fish and Wildlife Service or the Department of the Interior, often serving as wildlife refuges.
- Baker Island: An equatorial atoll in the central Pacific Ocean, claimed under the Guano Islands Act of 1856.
- Howland Island: Located near Baker Island, famous historically as the intended refueling destination for Amelia Earhart in 1937.
- Jarvis Island: A coral island located in the South Pacific administered as part of the Pacific Remote Islands Marine National Monument.
- Johnston Atoll: A lonely coral atoll once used by the military for missile testing and chemical weapon storage.
- Kingman Reef: A low-lying coral reef in the North Pacific with almost no dry land.
- Midway Atoll: Famous for the pivotal World War II naval battle, currently managed as a national wildlife refuge.
- Navassa Island: A small, uninhabited island in the Caribbean Sea claimed by the U.S. under the Guano Act, though contested by Haiti.
- Palmyra Atoll: The only incorporated territory currently remaining, meaning the U.S. Constitution applies fully and permanently there.
- Wake Atoll: A coral accolade in the North Pacific with an airfield used primarily by military and contractor personnel.
Freely Associated States: Independent Nations with U.S. Ties
People often confuse U.S. territories with the Freely Associated States. These are entirely sovereign, independent countries that have signed specific bilateral compacts with Washington.
- Federated States of Micronesia: An independent sovereign nation in the western Pacific.
- Republic of the Marshall Islands: An island nation near the equator in the Pacific Ocean.
- Republic of Palau: An island country consisting of about 340 islands in the western Pacific.
Under the Compacts of Free Association, the United States provides economic assistance and assumes responsibility for international defense and security. In exchange, citizens of these nations can travel, live, and work inside the United States without needing visas, and the U.S. military maintains exclusive operational access to their land and waters.

Frequently Asked Questions
Do people born in U.S. territories have American citizenship?
Most do. Individuals born in Puerto Rico, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands receive birthright U.S. citizenship under federal law. However, people born in American Samoa are classified as U.S. nationals rather than citizens, meaning they enjoy protected status and passport privileges but must complete a naturalization process to vote in certain jurisdictions.
Can residents of U.S. territories vote for the president?
No. Residents living permanently in U.S. territories cannot vote in the U.S. electoral college for president, nor do they have voting members in the United States Senate or House of Representatives. Each populated territory elects a single non-voting delegate to the House who can introduce legislation and sit on committees but cannot cast a final vote on bills.
Are U.S. territories considered foreign countries for travel?
For most practical and legal travel purposes, no. Traveling between the U.S. mainland and territories like Puerto Rico or the U.S. Virgin Islands is considered domestic travel. You don't need a passport to fly back to the mainland from Puerto Rico, though carrying a REAL ID-compliant driver's license or passport card is required for identification.
What is the difference between an incorporated and unincorporated territory?
An incorporated territory is an integral part of the United States to which the U.S. Constitution applies fully and irrevocably. Currently, Palmyra Atoll is the only incorporated territory. An unincorporated territory is a possession where the Supreme Court has ruled that only fundamental constitutional rights apply, giving Congress more flexibility in local governance.
