Largest Religion by Country with Exceptions

Just to help, here is a nonconclusive list of major denominations that I counted under one of the religions mentioned above: Buddhism- Esoteric, Mahayana, Theravada, Zen; Christianity- Catholocism, Eastern and Oriental Orthodoxy, Mormonism, Protestantism; Hinduism- Shaivism, Shaktism, Smartism, Vaishnavism; Islam- Shi'a, Sunni, Usuli, Wahhabi; and Judaism- Conservative, Orthodox, Reform.

Some countries have so few people who do not belong to the above religious groups that reliable sources don't exist for exact numbers. These countries are greyed out. Additionally, there are some cases where folk religion is not included because census data just clumps it all together, and I don't think it's fair to have "Angolan Folk Religions" as an answer for this quiz. If I can only find vague references to "folk religion" or "indigenous beliefs," then I use my best knowledge and research to infer what I can. In these cases, I put the religions under a generic non nation-specific term. There is one major exception.
