The Brazilian Catholic Church is the largest national community of believers in the world. Catholics there currently make up about 63% of the population, but the number of regular practitioners is estimated at 19-25%.
Recently, there has been an outflow of the faithful to communities mainly from the US, such as Jehovah's Witnesses, Mormons (about 1 million) Adventists, and various evangelical churches (such as Pentecostals).
