Section I. Religious Demography
The U.S. government estimates the total population at 9.5 million (midyear 2020 estimate). According to a 2016 survey by the state Information and Analytical Center of the Presidential Administration (the latest such data available), approximately 53 percent of the adult population belongs to the BOC and six percent to the Roman Catholic Church. According to the state survey, eight percent of the adult population is atheist, and 22 percent is “uncertain.” Smaller religious groups together constituting approximately two percent of the population include Jews, Muslims, Greek Catholics (“Uniates” or members of the Belarusian Greek Catholic Church), Old Believers (priestist and priestless), members of the Belarusian Autocephalous Orthodox Church and other Orthodox Christian groups, Lutherans, Jehovah’s Witnesses, Apostolic Christians, Presbyterians and other Protestant groups, Armenian Apostolics, Latin Catholics, members of the International Society of Krishna Consciousness, Baha’is, members of The Church of Jesus Christ of Latter-day Saints, and Buddhists. Jewish groups state there are between 30,000 and 40,000 Jews. Most ethnic Poles, who constitute approximately 3 percent of the population, are Roman Catholic.
