The U.S. government estimates the total population at 141.9 million (midyear 2019 estimate). A poll conducted during the year by the Public Opinion Foundation found that 65 percent of the population is Orthodox Christian, and 7 percent identify as Muslim. Religious groups constituting approximately 1 percent or less of the population each include Buddhists, Protestants, Roman Catholics, Jews, members of The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ), Jehovah’s Witnesses, Hindus, Baha’is, members of the International Society of Krishna Consciousness (ISKCON), pagans, Tengrists, Scientologists, and Falun Gong practitioners. The 2010 census estimates the number of Jews at 150,000; however, the Federation of Jewish Communities of Russia states the number of Jews is approximately one million, most of whom live in Moscow and St. Petersburg. The Russian Jewish Congress (RJC) estimates the Jewish population is nearly 1.5 million. According to Mufti Ravil Gaynutdin, chairman of the Religious Board of Muslims of the Russian Federation, the Muslim population reached 25 million in 2018, approximately 18 percent of the total population. Immigrants and migrant workers from Central Asia are mostly Muslim. The majority of Muslims live in the Volga-Ural Region and the North Caucasus. Moscow, St. Petersburg, and parts of Siberia also have sizable Muslim populations.
