Tanzania - Local government
Mainland Tanzania is divided into 20 administrative regions, which are subdivided into 86 districts. Zanzibar and Pemba are divided into five regions. Regional commissioners are appointed by the central government, as are district commissioners and development directors for the districts.
The units of local government are district development councils. Each district development council includes elected members, but these bodies are only advisory. In Zanzibar, revolutionary committees are responsible for regional administration.
