The country is an archipelago of 9 island groups with a total area of 10 square miles and a population of 9,700. The Church of Tuvalu, which has historic ties to the Congregational Church and other churches in Samoa, has the largest number of followers. Government estimates of religious affiliation as a percentage of the population include the Church of Tuvalu, 91 percent; Seventh-day Adventist, 3 percent; Baha'i, 3 percent; Jehovah's Witnesses, 2 percent; and Roman Catholic, 1 percent. There are also smaller numbers of Muslims, Baptists, and members of The Church of Jesus Christ of Latter-day Saints (Mormons). The Tuvalu Brethren Church, a new charismatic Protestant group, claims to have as many as 300 adherents.
All nine island groups have traditional chiefs, all of whom are members of the Church of Tuvalu. Most followers of other religious groups or denominations are found in Funafuti, the capital, with the exception of a relatively large number of followers of the Baha'i Faith on Nanumea Island.
