Black people have been members of Mormon congregations since its foundation, although the church placed restrictions on proselytization efforts among black people. Before 1978, black membership was small. It has since grown, and in 1997, there were approximately 500,000 black members of the church (about 5% of the total membership), mostly in Africa, Brazil and the Caribbean. Black membership has continued to grow substantially, especially in West Africa, where two temples have been built. By 2018, an estimated 6% of members were black worldwide. In the United States, approximately 1% of members are black.
