Christian statistics: The following list shows the countries with the largest numbers of Christians. Christianity, as defined for the purpose of census and surveys, includes all those who claim to be Christian. This includes varying degrees of religious activity, from essentially non-participating but still-nominal Christians to active full-communicants and life-long clergy. These numbers also include adherents of different divisions within Christianity, including Catholics, Eastern Orthodox, Protestant, Pentecostals, Jehovah's Witnesses, Latter-day Saints, African Indigenous Churches and others.

NOTE: There are many countries where very high percentages (95 to nearly 100%) of the population are Christians. There are so many, and they represent such a wide range of difficult-to-compare compositions in terms of activity, membership in European state churches, affiliation, etc., that it would be difficult to create a meaningful top 10 list of countries with the highest percentages of Christians. Please refer to the full Adherents.com for such information.
