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.
Ukrainian Brazilians
It should be also noticed that some Ukrainians were also Protestant, belonging to the Baptist and Pentecostals branch of Christianity. Originally coming from Volyn Region, they brought their Ukrainian traditions of worshipping God. The biggest church was the Russian Assembly of God (90% were Ukrainians and the rest Russians, Poles, Bielo Russians and few Lithuanians) based in São Paulo. It was founded around 1930 and led by Pr. Szymon Misiuk with branches in Arapongas -PR, Apucarana - PR, Curitiba - PR, Erexin and Santa Rosa - RS. São Caetano do Sul, in São Paulo State had a big concentration of Ukrainians as well and the First Ukrainian Baptist Church was established there by Rev. Dmitro Bucky. Many other churches were also based in São Paulo. The Ukrainian Protestants were not able to maintain their ethnic identity and with the oldtimers passing away, the new generation did not keep the tradition of services in Ukrainian language, churches disappeared or were turned into Brazilian churches, and Slavic connections disappeared.
