Demographics
As of 2010, the estimated population is 43,188,000. Population distribution is extremely uneven, with density varying from 1 person per square kilometre (3/mi²) in arid regions to 51 per square kilometre (133/mi²) in the well-watered mainland highlands, to 134 per square kilometre (347/mi²) on Zanzibar. More than 80% of the population is rural. Dar es Salaam is the largest city and is the commercial capital; Dodoma, located in the centre of Tanzania is the new capital and houses the Union's Parliament. The population consists of more than 120 ethnic groups, of which the Sukuma, Nyamwezi, Chagga, Nyakyusa, Haya, Hehe, Bena, Gogo, and the Makonde have more than 1 million members. Other Bantu peoples include the Pare, Zigua, Shambaa, and Ngoni. The majority of Tanzanians, including the Sukuma and the Nyamwezi, are Bantu. Cushitic peoples include the half million Iraqw. Nilotic peoples include the nomadic Maasai and Luo, both of which are found in greater numbers in neighbouring Kenya. The Sandawe speak a language that may be related to the Khoe languages of Botswana and Namibia, while the language of the Hadza, although it has similar click consonants, is a language isolate.
The population also includes people of Arab, Indian, and Pakistani origin, and small European and Chinese communities. Many also identify as Shirazis. As of 1994, the Asian community numbered 50,000 on the mainland and 4,000 on Zanzibar. An estimated 70,000 Arabs and 10,000 Europeans resided in Tanzania.
