Christianity is the largest religion in Tanzania representing 61% of the population. There are also substantial Muslim and Animist minorities. Current statistics on the relative sizes of various religions in Tanzania are limited because religious questions have been eliminated from government census reports since 1967. A 2010 survey from the Pew Research Center found that 61% of the population are Christian, 36% are Muslim, 2% practice traditional religions and 1% are unaffiliated.
