Note: Population data are compiled using statistical science and are subject to observational error; these numbers should therefore be considered estimates only. The total number of Christians for each country is based on the number of people who are members of a Christian denomination or who identify themselves as Christian, plus their children. The number of people who actually believe in God or who regularly attend church is not addressed. People who mix Christianity with tribal religions are counted as Christians in this article. Most of the numbers for the Christian percentage of the population for each country were taken from the US State Department's" International Religious Freedom Report", the" CIA World Factbook", Joshua Project, Open doors, Pew Forum, and Adherents.com.
