Islam is the religion of about 2 percent of Madagascar residents. Most of the rest of the population either have no religion or identify as Hindu or Jewish.
Roman Catholic, Reformed Protestant Church of Jesus Christ in Madagascar, Lutheran and Anglican denominations are the four primary Christian faiths in Madagascar. Traditional religious beliefs are based on ancestry worship, in which the dead are believed to reward or punish the living. Many people still practice traditional rites, particularly those rituals relating to the dead, while simultaneously following Christianity.
