Passage: Currently, there is no official census of religion in Russia, and estimates are based on surveys only. In 2012 the research organization Sreda published Arena Atlas, a detailed enumeration of religious populations and nationalities in Russia, based on a large-sample country-wide survey. They found that 46.8% of Russians declared themselves Christians (including 41% Russian Orthodox, 1.5% simply Orthodox or members of non-Russian Orthodox churches, 4.1% unaffiliated Christians, and less than 1% for both Catholic and Protestant), while 25% were spiritual but not religious, 13% were atheists, 6.5% were Muslims, 1.2% were followers of "traditional religions honoring gods and ancestors" (including Rodnovery, Tengrism and other ethnic religions), and 0.5% were Tibetan Buddhism. However, later that year, the Levada Center estimated that 76% of Russians were Christians, and in June 2013, the Public Opinion Foundation estimated that 65% of the population was Christian. These findings are in line with Pew Research Centers 2011 estimate that 73.6% of Russians were Christians, with Russian Public Opinion Research Center (VCIOM)s 2010 survey (~77% Christian), and with Ipsos MORIs 2011 survey (69%).
Did fewer people consider themselves atheist or Muslim? Did more people consider themselves spiritual but not religious or atheist? How many percent more considered themselves to be Russian Orthodox compared to unaffiliated Christian? How many percent of Russians did not declare themselves as Christian? How many percent of people were not Christians? How many percent of people were not Muslims? How many percent of people were not Orthodox? How many percent of people were not Russian Orthodox? How many percent of people were not atheists? How many percent of people were not spiritual but not religious? How many percent of people were not unaffiliated Christians? What was the smallest religious group identified in the study? Where there more people that considered themselves Russian Orthodox of non-Russian Orthodox? Which group did a study that had the highest percentage of Russians listed as Christians? Which study labeled the smallest number of Russians as Christian?
