Central Ukraine
According to a 2016 survey of religion in Ukraine held by the Razumkov Center, approximately 73.5% of the population of central Ukraine declared to be believers, while 4.8% declared to be non-believers, and 2.6% declared to be atheist. Of the total population, 86.5% were Christians (76.7% Eastern Orthodox, 6.5% simply Christians, 1.9% Latin Rite Catholics, 1.0% members of various Protestant churches, and 0.4% members of the Ukrainian Greek Catholic Church), 0.3% were Jewish, and 0.1% were Muslims. Not religious and other believers not identifying with any of the listed major religious institutions constituted about 12.8% of the population.
Ukrainian nationalism
At the same time, despite the ongoing Soviet-wide anti-religious campaign, the Ukrainian national Orthodox Church was created, the Ukrainian Autocephalous Orthodox Church. The church was initially seen by the Bolshevik government as a tool in their goal to suppress the Russian Orthodox Church, always viewed with great suspicion by the regime for its being the cornerstone of the defunct Russian Empire and the initially strong opposition it took towards the regime change. Therefore, the government tolerated the new Ukrainian national church for some time and the UAOC gained a wide following among the Ukrainian peasantry.
