Christian missions have long been active in Lesotho. As a result, according to 2002 estimates, about 90% of the population are Christian, with about 70% being Roman Catholic. Muslims, members of other non-Christian religions, and atheists make up the remaining 10%. The indigenous population, including many of its Christian members, follow African traditional religions. Some of the Catholic churches in the country incorporate traditional customs into worship, including traditional music, language, and dress. Christians are found throughout the country, while Muslims tend to be concentrated in the northeastern part of the country. Many of the Muslims are of Asian descent, while most of the Christians are indigenous Basotho.
