Guam is an island in the western South Pacific Ocean, about three-quarters of the way from Hawaiito the Philippines. (Geographic coordinates: 13 28 N, 144 47 E)
It is the largest and southernmost island in the Mariana Islandsarchipelago. Guam is a territory of theUnited States of America. It is considered to occupy a militarily strategic location, south of the Commonwealth of the Northern Mariana Islands. Guam is one of many islands that make up Micronesia, which politically consists of Belau (Palau), the Federated States of Micronesia (FSM), Kiribati (anthropologically having affinities with Polynesia and Micronesia), the Marshall Islands, and several remote islands designated as the U.S.-administered islands of the Central Pacific. All of Micronesia has close political ties to the U.S.
No true cities exist on Guam (if one uses the 50,000 person rule), but each "city" represents an individual township, all of which have mayors and limited autonomy within the central government. The largest population concentration is in the center of the island, since the south is fairly lightly populated and the north is mostly owned by the US military.
Most of the island's population is in the central metropolitan area (includes the cites of Tumon, Agana, Dededo, Barrigada, Tamuning and Agana Heights) (metro pop. ~120,000)
