Not including indigenous beliefs, non-Christian faiths total less than three percent of the population, though are nonetheless highly visible, particularly in urban areas. Followers of the Baháʼí Faith number over 160,000, or 1.5 percent of the population, which is among the largest communities in the world; the William Mmutle Masetlha Foundation, run by the Baháʼí community, is particularly active in areas such as literacy and primary health care. Approximately 0.5 percent of Zambians are Muslim, and a similar proportion are Hindu, in each case highly concentrated in urban areas. About 500 people belong to the Ahmadiyya community, which is variably considered an Islamic movement or a heretical sect. There is also a small but successful Jewish community, composed mostly of Ashkenazis.
