Some religious groups count actual members.
Others may estimate the total number of followers of their faith, and include even those individuals who have never attended a religious service. This makes the United States the third largest Roman Catholic country in the world, after Brazil and Mexico. These numbers are probably inflated, relative to most Protestant and other religious groups because the Catholic church counts as members everyone who has been baptized into the faith. A fascinating resource. Also included is some information about religions with small memberships in the U.S. and Canada, such as Islam, Judaism, etc.
