Religion
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,[note continued adherence to traditional beliefs also among Christians and Muslims:"(In Tanzania) more than half the people surveyed believe that sacrifices to ancestors or spirits can protect them from harm." see Pew report Christians and Muslims in Subsaharan Africa (2010)] 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.
