Most blacks are Christians, mainly Catholics. Afro-Brazilian religions such as Candomblé and Umbanda have many followers, but they are open to people of any race, and, indeed, while the proportions of blacks (in the strict sense, i.e., "pretos") are higher among practitioners of these religions than among the population in general, Whites are a majority in Umbanda, and a significant minority (bigger than blacks in the strict sense) in Candomblé. They are concentrated mainly in large urban centers such as Salvador, Recife, Rio de Janeiro, Porto Alegre, Brasília, São Luís. In addition to Candomblé which is closer to the original West African religions, there is also Umbanda which blends Catholic and Kardecist Spiritism beliefs with African beliefs. Candomblé, Batuque, Xango and Tambor de Mina were originally brought by enslaved Africans shipped from Africa to Brazil.
