Society and culture
Population
As of 2009, the estimated population was 43,739,000. More than 80 percent of the population is rural(living in less-populated, non-urban areas). The population consists of more than 120 ethnic groups: the Sukuma and Nyamwezi, the Hehe and Bena, the Gogo, the Haya, the Makonde, the Chagga and the Nyakyusa have more than 1 million members. Other groups include the Pare, Shambaa (or Shambala), and Ngoni. The population also includes people of Arab, Indian, and Pakistani origin, and small European and Chinese communities.
Languages
Tanzanian law no longer constitutes English as the official language. However, it can still be considered as an official language because it is still the language of higher courts. Tanzanians therefore see themselves as having two official languages: English and Swahili. Swahili is the unifying(promoting unity) language of the country between different tribes(a socially, ethnically, and politically cohesive group of people) who each have their own tribal language. English provides Tanzanians with the ability to participate in the global economy and culture.
Religion
The religious balance is seen as a sensitive topic in Tanzania. The population has been estimated to consist of Christians (30%), Muslims (30%) and followers of indigenous(native to an area) religious groups (30%). There are a few communities of other religious groups, such as Buddhists, Hindus, and Baha'is.
