The proportion of Christians is based on the proportion of the population in each country who are members of a Christian denomination or who identify themselves as Christian. It says nothing about the proportion of such as believe in God and are regularly in the church. People who mix Christianity with tribal religions are defined in this article as Christians. Most of the percentage of Christian population of each country was taken from the US State Department's International Religious Freedom Report, the CIA World Factbook, Joshua Project, Open doors, Pew Forum and Adherents.com.
