An estimated 60% of the population follow traditional African religions. Even some who identify themselves as Christian or Muslim are likely to observe some traditional indigenous customs as well. The most common indigenous religion is Vodoun. Vodoun spread to the Americas with slavery and later became a source for African-inspired religions such as Santeria (in the Spanish-speaking Caribbean), voodoo (in Haiti), and Candomble (in Brazil). The Vodoun religion is based on a belief in one supreme being who rules over a number of lesser deities, spirits, and saints.
About 30% of the population are nominally Christian, with a majority belonging to the Roman Catholic church. Other denominations include Methodists, Baptist, Assembly of God, Jehovah's Witnesses, The Church of Jesus Christ of the Latter Day Saints, Celestial Christians, Seventh-Day Adventists, Rosicrucians, the Unification Church, Eckanka, and the Baha'i faith. About 20% of the population are Sunni Muslim. Certain Christian and Muslim holidays are officially observed, along with one traditional indigenous holiday.
