According to the U.S. Religious Landscape Survey, conducted in 2007 by the Pew Research Center’s Forum on Religion & Public Life, Black Americans “are markedly more religious on a variety of measures than the U.S. population as a whole.” It cited that 87% of Blacks (vs. 83% of all Americans) are affiliated with a religion. It also found that 79 % of Blacks (vs. 56% overall) say that religion is “very important in their life”.
Many scholars estimate that 15-30% of Africans imported as slaves were Muslim. The majority of the remaining practiced indigenous forms of worship. All were converted to Christianity. Most became Baptist although slaves from Louisiana became Catholic because of the French settlers in that area. Today 83% of African Americans are Christian, and only 1% identify themselves as Muslim.
