Lists

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.
