Southern Ukraine
According to a 2016 survey of religion in Ukraine conducted by the Razumkov Center, around 65.7% of the population of southern Ukraine declared to be believers in any religion, while 7.4% declared to be non-believers, and 3.2% declared to be atheists and agnostics. the study also found that 77.6% of the total Southern Ukraine population declared to be Christians (71.0% Eastern Orthodox, 5.1% simply Christians, 0.5% Latin Rite Catholics, 0.53% members of various Protestant churches, 0.5% members of the Ukrainian Greek Catholic Church), and 0.5% were Jewish. Not religious and other believers not identifying with any of the listed major religious institutions constituted about 24.7% of the population.
Ukrainization
At the same time, despite the ongoing Soviet-wide anti-religious campaign, the Ukrainian national Orthodox Church was created, the Ukrainian Autocephalous Orthodox Church (See History of Christianity in Ukraine). The Bolshevik government initially saw the national churches 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.
