The government bureaucracy is composed of traditional ministries, special agencies, and parastatal companies. The Ministry of Interior spearheads a system of regional governors and prefects modeled on the French system of local administration. Under this system, Mauritania is divided into 15 regions (wilaya or régions).
Control is tightly concentrated in the executive branch of the central government, but a series of national and municipal elections since 1992 have produced limited decentralization. These regions are subdivided into 44 departments (moughataa). The regions and capital district (in alphabetical order) and their capitals are:
