Survey Data

A survey by the Pew Forum on Religion and Public Life, “Tolerance and Tension: Islam and Christianity in Sub-Saharan Africa,” sheds light on a number of aspects Tanzanian culture.1 The study does not differentiate between Catholics and other Christians, but provides a useful frame for understanding Catholicism in Tanzania. 

In the Pew study 60% of Tanzanians identify as Christian (51% of these as Catholic, 44% as Protestant), 36% as Muslim, 2% as affiliated with traditional African religions, 1% as unaffiliated. The largest Protestant identities are Lutheran (8% of the population), Pentecostal (6%), Anglican (6%) and African Independent churches (3%).  32% of respondents in the Pew survey said they were raised Catholic, and 31% said they were now Catholic; 23% said they were raised Protestant, but 27% are now Protestant.

44% of Tanzanians say their lives have improved since five years ago; 50% think their lives will be better in five years. This latter number puts them on the low end of the spectrum compared to other African neighbors surveyed.
