Religious Adherents, 2010 (World Christian Database)1
The country has an area of 43,000 square miles and a population of 3.5 million. It is estimated that as much as 40 percent of the population practices either Christianity or Christianity combined with elements of traditional indigenous religious beliefs. Approximately 40 percent exclusively practices traditional indigenous religious beliefs. An estimated 20 percent of the population practices Islam. A small percentage is Baha'i, Hindu, Sikh, or Buddhist.
Christian groups include Lutheran, Baptist, Episcopal, Presbyterian, Roman Catholic, Church of Jesus Christ of Latter Day Saints (Mormons), Seventh-day Adventists, United Methodist, African Methodist Episcopal (AME) and AME Zion denominations, and a variety of Pentecostal churches. Some of the Pentecostal movements are affiliated with churches outside the country, while others are independent.
Christians live throughout the country. Muslims belong mainly to the Mandingo and Vai ethnic groups. Mandingo reside throughout the country, while Vai live predominantly in the west. Ethnic groups in all regions participate in the traditional religious practices of the Poro and Sande secret societies.
Note: The World Christian Database (WCD) estimates, used in the Religious Adherents section above, count each person as belonging to a maximum of one religious group. For more information, see the WCD methodology document. The U.S. State Department's International Religious Freedom report estimates, used in the Religious Demography section, use less restrictive criteria in which a person who identifies with more than one religion is classified as a follower of each. In certain cases (such as Japan and other nations with strong folk religion traditions), this can cause counts to vary widely between estimates. Users are advised to consult the relevant source documents before determining which counts to cite.
1. The World Christian Database (WCD) is based on the 2600-page award-winning World Christian Encyclopedia and World Christian Trends, first published in 1982 and revised in 2001. This extensive work on World religion is now completely updated and integrated into the WCD online database. Designed for both the casual user and research scholar, information is readily available on religious activities, growth rates, religious literature, worker activity, and demographic statistics. Additional secular data is incorporated on population, health, education, and communications. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. Used with permission.
2. The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.
