The Philippines is a secular nation having a constitution separating the state and church. However, more than 90% of the population are Christians: about 80% belong to the Roman Catholic Church while 10% belong to other Christian denominations, such as the Iglesia ni Cristo, the Philippine Independent Church, the Seventh-day Adventist Church, United Church of Christ in the Philippines, and Jehovah's Witnesses. The Philippines is one of two predominantly Roman Catholic countries in Asia, the other being East Timor.
Between 5 and 10% of the population are Muslim, most of whom live in parts of Mindanao, Palawan, and the Sulu Archipelago—an area known as Bangsamoro or the Moro region. Some have migrated into urban and rural areas in different parts of the country. Most Muslim Filipinos practice Sunni Islam according to the Shafi'i school. Philippine traditional religions are still practiced by many aboriginal and tribal groups, often syncretized with Christianity and Islam. Animism, folk religion, and shamanism remain present as undercurrents of mainstream religion, through the albularyo, the babaylan, and the manghihilot. Buddhism, Taoism, and Chinese folk religion, are dominant in Chinese communities. There are also followers of Hinduism, Sikhism, and Judaism and Baha'i
