However, in the last ten years Protestantism, particularly in forms of Pentecostalism and Evangelicalism, has spread in Brazil, while the proportion of Catholics has dropped significantly. After Protestantism, individuals professing no religion are also a significant group, exceeding 8% of the population as of the 2010 census. The cities of Boa Vista, Salvador, and Porto Velho have the greatest proportion of Irreligious residents in Brazil. Teresina, Fortaleza, and Florianópolis were the most Roman Catholic in the country. Greater Rio de Janeiro, not including the city proper, is the most irreligious and least Roman Catholic Brazilian periphery, while Greater Porto Alegre and Greater Fortaleza are on the opposite sides of the lists, respectively.
