serves as long as the council is satisfied with their work. Unincorporated areas Some states contain unincorporated areas, which are areas of land not governed by any local authorities below that at the county level. Residents of unincorporated areas only need to pay taxes to the county, state and federal governments as opposed to the municipal government as well. A notable example of this is Paradise, Nevada, an unincorporated area where many of the casinos commonly associated with Las Vegas are situated. Special-purpose local governments In addition to general-purpose government entities legislating at the state, county, and city level, special-purpose areas may exist as well, provide one or more specific services that are not being supplied by other existing governments. School districts are organized local entities providing public elementary and secondary education which, under state law, have sufficient administrative and fiscal autonomy to qualify as separate governments. Special districts are authorized by state law to provide designated functions as established in the district's charter or other founding document, and with sufficient administrative and fiscal autonomy to qualify as separate governments; known by a variety of titles, including districts, authorities, boards, commissions, etc., as specified in the enabling state legislation. Unincorporated territories The United States possesses a number of unincorporated territories, including 16 island territories across the globe. These are areas of land which are not under the jurisdiction of any state, and do not have a government established by Congress through an organic act. Citizens of these territories can vote for members of their own local governments, and some can also elect representatives to serve in Congress—though they only have observer status. The unincorporated territories of the U.S. include the permanently inhabited territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands; as well as minor outlying islands such as Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Navassa Island, Palmyra Atoll, Wake Island, and others. American Samoa is the only territory with a native resident population and is governed by a local authority. Despite the fact that an organic act was not passed in Congress, American Samoa established its own constitution in 1967, and has self governed ever since. Seeking statehood or independence is often debated in US territories, such as in Puerto Rico, but even if referendums on these issues are held, congressional approval is needed for changes
