Special districts (also known as special service districts, special district governments, limited purpose entities, or special-purpose districts in the United States) are independent, special-purpose governmental units that exist separately from local governments such as county, municipal, and township governments, with substantial administrative and fiscal independence. They are formed to perform a single function or a set of related functions. The term special district governments as defined by the U.S. Census Bureau excludes school districts. In 2007, the U.S. had more than 39,000 special district governments.
