The U.S. government estimates the population at 142.4 million (July 2016 estimate). The most recent figures from a 2013 poll by the Levada Center, an NGO research organization, reports 68 percent of Russians consider themselves Orthodox, while 7 percent identify as Muslim. Religious groups constituting less than 5 percent of the population each include Buddhists, Protestants, Roman Catholics, Jews, Mormons, Jehovah’s Witnesses, Hindus, Bahais, the International Society of Krishna Consciousness (ISKCON), pagans, Tengrists, Scientologists, and Falun Gong adherents. The 2010 census estimates the number of Jews at 150,000; however, the president of the Federation of Jewish Communities of Russia stated in February 2015 the actual Jewish population is nearly one million, most of who live in Moscow and St. Petersburg. 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.
