Brazilian religions are very diversified and inclined to syncretism. In recent decades, there has been a great increase of Neo-Pentecostal churches and a thriving of Afro-Brazilian religions, which have decreased the number of members of the Roman Catholic Church. The number of Umbandists and Candomblers could be significantly higher than the official census figure, since many of them continue to this day to disguise their religion under "Catholic" syncretism. About ninety percent of Brazilians declared some sort of religious affiliation in the most recent census.
