According to the 2010 ''Tanzania Demographic and Health Survey 2010'', 15 per cent of Tanzanian women had undergone female genital mutilation (FGM) and 72 per cent of Tanzanian men had been circumcised. FGM is most common in the Manyara, Dodoma, Arusha, and Singida regions and nonexistent in Zanzibar. The prevalence of male circumcision was above 90 per cent in the eastern (Dar es Salaam, Pwani, and Morogoro regions), northern (Kilimanjaro, Tanga, Arusha, and Manyara regions), and central areas (Dodoma and Singida regions) and below 50 per cent only in the southern highlands zone (Mbeya, Iringa, and Rukwa regions).
