The exact number is not officially fixed, but a reasonable estimate for North America is about 150,000 to 200,000 Jains. Academic sources note that the exact number is unknown, JAINA says it represents about 150,000 members in the U.S. and Canada, and some community estimates place the total above 200,000.
