Christianity by country
As of the year 2023, Christianity had approximately 2.4 billion adherents and is the largest religion by population.[2] According to a PEW estimation in 2020, Christians made up to 2.38 billion of the worldwide population of about 8 billion people.[a][3][4][5][6][7] It represents nearly one-third of the world's population and is the largest religion in the world, with the three largest groups of Christians being the Catholic Church, Protestantism, and the Eastern Orthodox Church.[8] The largest Christian denomination is the Catholic Church, with 1.3 billion baptized members.[9] The second largest Christian branch is either Protestantism (if it is considered a single group), or the Eastern Orthodox Church (if Protestants are considered to be divided into multiple denominations).

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.
