Muslims are found throughout the country, while Orthodox followers are concentrated in the south and Catholics are concentrated in the north. However, this division is not strict, particularly in many urban centers, which have mixed populations. Members of the Greek minority, concentrated in the south, belong almost exclusively to the Greek Orthodox Church. In addition to the four traditional religious groups, there are substantial numbers of followers of Protestant denominations, Baháʼís, Jehovah's Witnesses, the Church of Jesus Christ of Latter-day Saints (Mormons), and other religious groups.
