The country has an area of 13,948 square miles and a population of 1.5 million. Approximately one-half the population follows indigenous religious practices. Of the remainder, an estimated 40-45 percent is Muslim and 5-10 percent is Christian.
Islam is practiced most widely by the Fula and Mandinka ethnic groups; Muslims generally live in the north and northeast. Virtually all Muslims are Sunni. The number of Ahmadis is extremely small and not confined to any particular geographic region. Practitioners of indigenous religious beliefs generally live in all but the northern parts of the country. Christians belong to a number of groups, including the Roman Catholic Church and various Protestant denominations. Christians are concentrated in Bissau and other large towns.
