U.S. Territories Map
U.S. Territories Map:
The United States of America holds claim to 16 territories outside of the United States. These range from Puerto Rico, with over 140 smaller islands and over 3 million residents, to uninhabited territories (and disputed territories) such as Bajo Nuevo Bank, Navassa Island, Serranilla Bank, and Wake Island. The United States has many political, defensive, social and other reasons to claim these territories as important lands of the United States. However, another important reason to claim them is for their resource potential. Those territories that consist of an island or a cluster of islands are surrounded by sea floors that may contain important mineral, energy, and food resources. By claiming them, the United States claims rights to an exclusive economic zone that extends up to 200 miles offshore (or half of the distance to the nearest shoreline claimed by another sovereign state).
U.S. Exclusive Economic Zones Map:
The map above shows the geographic importance of the exclusive economic zones. Although the United States claims only a few islands in the Pacific Ocean, these territories give the U.S. exclusive economic claim to an enormous extent of the Pacific Ocean seafloor. These areas might be underlain by oil and gas, stratified mineral resources, or mineral materials in the shallow seafloor sediments. These might also have potential as important fishing, aquaculture, or marine ecosystem areas.

Inhabited Territories of the United States (5):
American Samoa: A group of islands (5 volcanic islands and 2 coral atolls) in the South Pacific Ocean, located about halfway between Hawaii and New Zealand. American Samoa lies just southeast of the Independent State of Samoa, from which it was separated in 1899. Over 50,000 people live in American Samoa, and people born there are considered non-citizen nationals of the United States.
Guam: An island in the North Pacific Ocean. It is the southernmost and largest island in the Mariana Islands archipelago. It has a population of approximately 162,000. People born in Guam are granted U.S. citizenship.
Northern Mariana Islands: A group of 15 islands in the North Pacific Ocean. There are over 50,000 people living in the Northern Mariana Islands, with the majority living on the island of Saipan. People born in the Northern Mariana Islands are granted U.S. citizenship.
Puerto Rico: Includes the main island of Puerto Rico and over 140 smaller islands in the Caribbean Sea. Puerto Rico is the largest and most populous of the U.S. territories, with over 3 million residents. People born in Puerto Rico are granted U.S. citizenship.
U.S. Virgin Islands: Located in the Caribbean Sea, just east of Puerto Rico. They include the three main islands of St. Thomas, St. John, and St. Croix, along with nearly 80 smaller surrounding islands. Over 100,000 people reside in the USVI. People born in the USVI are granted U.S. citizenship.
Uninhabited Territories of the United States (7):
Baker Island: An atoll in the Pacific Ocean. It lies just north of the equator, about halfway between Hawaii and Australia. It is a National Wildlife Refuge for seabirds, shorebirds, and marine wildlife such as turtles.
Howland Island: A coral island in the Pacific Ocean, located slightly northwest of Baker Island. Howland Island was to be a refueling stop for Amelia Earhart during her 1937 flight around the world, but Earhart and her airplane mysteriously disappeared without reaching the island. Today, Howland Island is a National Wildlife Refuge.
Jarvis Island: A coral island in the Pacific Ocean, located just south of the equator and about halfway between Hawaii and the Cook Islands. It is a National Wildlife Refuge for seabirds, shorebirds, and marine wildlife.
Johnston Atoll: Comprised of four islands atop a coral reef platform. It is located about 860 miles southwest of Hawaii. Coral dredging was used to quadruple the size of Johnston Island and double the size of Sand Island. The artificial islands of Akau and Hikina were also created with coral dredging. Although Johnston Atoll was controlled by the U.S. military for many decades, today it is administered as a National Wildlife Refuge.
Kingman Reef: A partially submerged reef located about one-third of the way between Hawaii and American Samoa in the North Pacific Ocean. Above sea level, the reef is often awash and cannot support permanent plant and animal life. However, it is a National Wildlife Refuge for a diverse variety of marine wildlife.
Midway Atoll: Named due to the fact that it is an atoll about midway between Asia and North America. It is also approximately halfway around the world from the prime meridian. Midway Atoll is part of the Hawaiian archipelago but not part of the state of Hawaii. Although there are no permanent inhabitants, there are residential facilities available for U.S. Fish and Wildlife Service staff. The atoll is a National Wildlife Refuge which hosts Hawaiian monk seals, green sea turtles, spinner dolphins, squid, octopus, crustaceans, fish, various seabirds, and the world's largest colony of Laysan albatrosses.
Palmyra Atoll: A cluster of about 50 islets in the North Pacific Ocean, just southeast of Kingman Reef. There are no permanent inhabitants, but there are facilities and a research station for temporary residents such as scientists and scholars. The atoll is a National Wildlife Refuge.
