The population distribution in Tanzania is extremely uneven. Most people live on the northern border or the eastern coast, with much of the remainder of the country being sparsely populated.[1]: 1252 Density varies from 12 per square kilometre (31/sq mi) in the Katavi Region to 3,133 per square kilometre (8,110/sq mi) in Dar es Salaam.[2]: 6 Approximately 70 percent of the population is rural, although this percentage has been declining since at least 1967.[3]Dar es Salaam is the de facto capital and largest city. Dodoma, located in the centre of Tanzania, is the de jure capital, although action to move government buildings to Dodoma has stalled.
Non-Africans residing on the mainland and Zanzibar account for 1 percent of the total population. The Asian community including Hindus, Sikhs, Shi'a and Sunni Muslims, Parsis, and Goans, exceed 60,000. An estimated 70,000 Arabs and 20,000 Europeans (90 percent of which are from the British diaspora) reside in Tanzania. Over 100,000 people living in Tanzania are of Asian or European ancestry.[10]
According to the 2012 census, the total population was 44,928,923 compared to 12,313,469 in 1967,[2]: 1 resulting in an annual growth rate of 2.9 percent. The under 15 age group represented 44.1 percent of the population, with 35.5 percent being in the 15–35 age group, 52.2 percent being in the 15–64 age group, and 3.8 percent being older than 64.[12]
According to the 2012 revision of the World Population Prospects, children below the age of 15 constituted 44.8 percent of the total population, with 52.0 percent aged 15–64 and 3.1 percent aged 65 or older.[13]

Vital statistics
The Tanzanian Demographic and Health Survey 2010 estimated that the infant mortality rate for 2005–10 was 51.[16] Registration of other vital events in Tanzania is not complete. The Population Department of the United Nations prepared the following estimates.[17]
Fertility rates are estimated by Surveys (TDHS) and Census in different times.
TDHS surveys estimated these fertility rates: 6.3 (1991–92), 5.8 (1996), 5.7 (2004–05), 5.4 (2010)
and 2002 Census said 6.3 [21]

rate of urbanization: 5.22% annual rate of change (2015-20 est.)

Most Tanzanians are nowadays Christians and Muslims. The numerical relationship between followers of the two religions is regarded as politically sensitive and questions about religious affiliation have not been included in census questionnaires since 1967.
For many years estimates have been repeated that about a third of the population each follows Islam, Christianity and traditional religions.[32]
As there is likely no longer such a large percentage of traditional religionists,[33] a range of competing estimates has been published giving one side or the other a large share or trying to show equal shares.
Estimates from the Pew Report Islam and Christianity (2010) were 60% Christian and 36% Muslim.[34]
The remainder of the population are Hindus, Buddhists, animists, and unaffiliated. Most Christians are Roman Catholic, Lutheran, Anglican or Pentecostal, though a number of other churches, as Seventh-Day Adventist, and Eastern Orthodox Christians are also represented in the country. Most Tanzanian Muslims are Sunni Muslims, though there are also populations of Ibadi, Shia, Ahamadiya, Bohora. Muslims are concentrated in coastal areas and in mainland areas along former caravan trade routes.
