Roman Catholicism is Belgium's majority religion with 75% of the people practicing it. Other religions prevalent in Belgium are Islam (3.5%), Protestantism and Judaism (both less than 1%). Hinduism and Buddhism also have some followers in Belgium.
Although regular church attendance is high in the Flemish region and the Ardennes, it has decreased in the Walloon industrial region and in Brussels.
Religion has often played an important role in Belgium's politics. The constitution provides for freedom of religion, and the government generally respects this right in practice.
