The U.S. government estimates the total population at 2.2 million (July 2013 estimate). Although there are no official statistics on religious affiliation, more than 90 percent of the population reportedly identifies as Christian. Religious leaders estimate that 60 percent of Christians identify as Lutheran, 20 percent as Catholic, and 10 percent as Anglican. Other denominations, including Baptist, Methodist, Pentecostal, and evangelical and charismatic churches, as well as the Church of Jesus Christ of Latter-day Saints (Mormons) and the Dutch Reformed Church of Namibia, make up the remaining 10 percent of the Christian population. The number of Pentecostal churches is growing, primarily in the northern Zambezi Region. A number of Zionist churches combine Christianity and traditional African beliefs. There are also small numbers of Muslims, Bahais, Jews, and Buddhists, primarily in urban areas.
Members of the Dutch Reformed Church are predominantly ethnic Afrikaners. Members of the Himba and San ethnic groups often combine indigenous religious beliefs with Christianity. Muslims are mostly Sunni and are predominantly immigrants from elsewhere in Africa or recent converts.
