Chuuk is one of the four states in the Federated States of Micronesia (FSM), which is an independent republic in free association with the United States. Chuuk includes Chuuk Lagoon, with the main island of Weno and many islands in the regions of Nómwoneas  (Fonoton, Piis-Panewu, Tonoas, Fefen, Parem, Siis, Etten, Uman) and Fáichuk (Udot, Eot, Ramanum, Fanapanges, Pwene, Paata, Onei, Tol). Chuuk State also includes several smaller islands and atolls — the Mortlock Islands (Nema, Losap, Pisemwar, Kuttu, Mòch, Tà, Namoluk, Ettal, Lukunor, Satowan) and the Northwestern Islands (Kuop [uninhabited], Murilo, Nomwin, Fananu, Ruo, East Fayu [uninhabited], Nómwonweité, Polowat, Pollap, Houk, Tamatam). About 29% of Chuuk’s population lives in the outer islands, while 40% live in Weno. [1]
