Which one of the following is the most dominant religion in Thailand in terms of its followers?

Buddhism is the most dominant religion in Thailand, with approximately 93% to 95% of the population practicing Theravada Buddhism. It is deeply integrated into the nation's identity, culture, and governance; for instance, the Thai constitution stipulates that the Monarch must be a Buddhist. While Thailand is a secular state that guarantees religious freedom, Buddhism remains the primary spiritual and social force.

Other religious groups in Thailand are significantly smaller: Islam is the second-largest religion (approx. 4-5%), followed by Christianity (approx. 1%). Hinduism, Sikhism, and Judaism represent very small minorities, while Jainism has almost no historical or demographic presence in the country.
