Answered by GPT-5 mini AI
Estimates vary by source and year, but as of the early 2020s roughly 1.9–2.0 billion people worldwide identify as Muslim. That is about 24–25% of the global population, making Islam the second-largest religion after Christianity.

Notes:
- Different counts use different definitions (self-identification vs. practicing), so precise totals vary by source.
- If you want, I can give a source (e.g., Pew Research Center or World Religion Database) or a country-by-country breakdown.
