The country has an area of 320,827 square miles and a population of 2 million. More than 90 percent of the population identifies itself as Christian. The three largest Christian groups are the Lutheran, Roman Catholic, and Anglican churches, while smaller numbers are affiliated with the Baptist, Methodist, and Pentecostal and evangelical (charismatic) churches, as well as The Church of Jesus Christ of Latter-day Saints (Mormons). The number of Pentecostal churches is growing significantly. There are also a number of Zionist Churches (which practice a mixture of traditional African beliefs and Pentecostal Christianity), especially in urban areas. The Dutch Reformed Church of Namibia predominantly is made up of members of the Afrikaner ethnic group. The Himba, Herero, and San groups practice indigenous religions. There are also Muslims, Baha'is, Jews, and Buddhists; they reside primarily in urban areas. Muslims are almost exclusively Sunni and are predominantly immigrants or recent converts.
