From Quiz Southeast Asia, Grouped and Ordered
Answer:
Majority religions (Theravada Buddhism, Islam, Christianity, Mahayana Budhism)
In 2015, Indonesia was by far the most populous Muslim nation on Earth, and the population of Muslims in Southeast Asia was only slightly smaller than the total population of Muslims in the Arab world. Both Theravada and Mahayana Buddhism entered Southeast Asia from India in the first few centuries AD. The Mahayana tradition mostly died out during the height of the Khmer empire, but Mahayana Buddhism was re-introduced to Vietnam during its period of Chinese domination. Catholicism was introduced to the Philippines by the Spaniards. Singapore does not have a single religion with majority support.
