Tunisia has a sizable Christian community of around over 35,000 adherents,[174][175] mainly Catholics (22,000) and to a lesser degree Protestants. Berber Christians continued to live in some Nefzaoua villages up until the early 15th century[176] and the community of Tunisian Christians existed in the town of Tozeur up to the 18th century.[54] International Religious Freedom Report for 2007 estimates thousands of Tunisian Muslims have converted to Christianity.[177][178] Judaism is the country's third largest religion with 900 members. One-third of the Jewish population lives in and around the capital. The remainder lives on the island of Djerba with 39 synagogues where the Jewish community dates back 2,600 years,[179] in Sfax, and in Hammam-Lif.[180]
