Subdivisions of Tanzania

The administrative divisions of Tanzania are controlled by Part I, Article 2.2 of the Constitution of Tanzania. Tanzania is divided into thirty-one regions ("mkoa in Swahili"). Each region is subdivided into districts ("wilaya in Swahili"). The districts are sub-divided into divisions ("tarafa in Swahili") and further into local wards ("kata in Swahili"). Wards are further subdivided for management purposes: for urban wards into streets ("mtaa in Swahili") and for rural wards into villages ("kijiji in Swahili"). The villages may be further subdivided into hamlets ("vitongoji in Swahili").

A village is the lowest government administrative structure at the community level. In an urban area, a cluster (mtaa) can include a number of streets. A Ward (Kata) is an administrative structure for one single town or portion of a bigger town (Urban Wards). Rural wards are composed of several villages.
