In 2018, according to a study jointly conducted by London's St Mary's University's Benedict XVI Centre for Religion and Society and the Institut Catholique de Paris, and based on data from the European Social Survey 2014–2016, Christianity is declining in Russia like in Western Europe. Among the 16 to 29 years-old Russians, 41% were Christians (40% Orthodox and 1% Protestant), 10% were of other religions (9% Muslim and 1% other), and 49% were not religious.
In 2015, the Pew Research Center estimated that 71% of Russians were Orthodox Christians, 15% were not religious, 10% were Muslim, 2% were Christians of other denominations, and 1% belonged to other religions.[32] https://en.wikipedia.org/wiki/Religion_in_Russia
