Religions 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. As there is likely no longer such a large percentage of traditional religionists, 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. 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. See also List of ethnic groups in Tanzania References
