High Quality Content by WIKIPEDIA articles! The Dinka are an ethnic group inhabiting the Bahr el Ghazal region of the Nile basin, Jonglei and parts of southern Kordufan and Upper Nile regions. They are mainly agripastoral people, relying on cattle herding at riverside camps in the dry season and growing millet (awuou) and other varieties of grains (rap) in fixed settlements during the rainy season. They number around 4.5 million people according to the 2008 Sudan census, constituting about 18% of the population of the entire country, and the largest ethnic tribe in South Sudan. Dinka, or as they refer to themselves, Muonyjang (singular) and jieng (plural), are one of the branches of the River Lake Nilotes (mainly sedentary agripastoral peoples of East Africa who speak Nilotic languages, including the Nuer and Luo). Dinka are sometimes noted for their height. With the Tutsi of Rwanda, they are believed to be the tallest people in Africa. Roberts and Bainbridge reported the average height of 182.6 cm (5 ft 11.9 in) in a sample of 52 Dinka Ageir and 181.3 cm (5 ft 11.4 in) in 227 Dinka Ruweng measured in 1953–1954. However, it seems the stature of today`s Dinka males is lower, possibly as a consequence of undernutrition and conflicts. An anthropometric survey of Dinka men, war refugees in Ethiopia, published in 1995 found a mean height of 176.4 cm (5 ft 9.4 in).
