Answered by GPT-5 mini AI
About 2.3–2.4 billion people worldwide identify as Christian — roughly 29–31% of the global population. (Estimates vary by source and year; for example, the Pew Research Center’s recent counts and projections put the number around 2.3–2.38 billion.)

Rough internal breakdown (approximate):
- Roman Catholics: ~1.2–1.4 billion
- Protestant and other non-Catholic groups (including Evangelicals, Anglicans, mainline Protestants): ~600–900 million
- Eastern Orthodox: ~200–300 million

Numbers change over time with population growth and conversion, and different sources use slightly different definitions, so let me know if you want a source citation, a year-specific estimate, or a country-by-country breakdown.
