The country has an area of 157,047 square miles and a population of 7 million. According to the 2002 national census, 89.6 percent of the population is Roman Catholic and 6.2 percent is evangelical Protestant. Jehovah's Witnesses, Jews (Orthodox, Conservative, and Reform), members of The Church of Jesus Christ of Latter-day Saints (Mormons), Muslims, Buddhists, adherents of the Unification Church, and members of the Baha'i Faith also are present.
Native-born citizens tend to be Catholic, while immigrants generally belong to other religious groups. The department of Alto Parana has a large Muslim community due to substantial immigration from the Middle East, particularly Lebanon. Mennonite communities flourish in the departments of Boquerón and San Pedro. Members of other religious groups are concentrated in the largest cities, including Asunción, Ciudad del Este, and Encarnación.
