It is presently estimated that about one-half the population follows traditional African religions while most of the rest are nominally Christian. Anglicans, Methodists, and the United Congregational Church of Southern Africa—formerly the London Missionary Society—claim the largest numbers of Christian followers. There are also congregations of Lutherans, Roman Catholics, the Church of Jesus Christ of Latter-Day Saints, Seventh-Day Adventists, Jehovah's Witnesses, Baptists, the Dutch Reformed Church, Mennonites, and other Christian denominations. About 1% of the population is Muslim and about 1% is Hindu. Freedom of religion is constitutionally guaranteed. Certain Christian holidays are officially observed.
