About 90% of Barbados' population is of African descent, 4% European descent, and 6% Asian or mixed. About 40% of Barbadians are Anglican, and the rest mostly Roman Catholic, Methodist, Baptist, and Moravian. There also are small Jewish and Muslim communities. Barbados' population growth rate has been very low, less than 1% since the1960s, largely due to family planning efforts and a high emigration rate.
