Geography of Micronesia
The Federated States of Micronesia (FSM) consists of 607 islands extending 1,800 miles across the archipelago of the Caroline Islands east of the Philippines. The four constituent island groups are Yap, Chuuk (called Truk until January 1990), Pohnpei (called Ponape until November 1984), and Kosrae. The federal capital is Palikir, on Pohnpei.

The indigenous population, which is predominantly Micronesian, consists of various ethnolinguistic groups. English has become the common language. Population growth remains high at more than 3%, ameliorated somewhat by net emigration.
