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.
Religion in Tajikistan
The next largest religious community is presumably Russian Orthodox, the historical faith of many Ukrainians as well as Russians. A cathedral in Dushanbe, St. Nicholas, serves the Orthodox community. By the end of the Soviet era, Tajikistan also was home to small numbers of people belonging to other Christian denominations, including Roman Catholics (originally most of them were from German origins, but also Tajiks), Seventh-Day Adventists, and Baptists. There also was a small Armenian minority, most of whose members belonged historically to the Armenian Apostolic (Gregorian) Church. Other religious groups included Zoroastrians and small numbers of Jews and Baha'is. The number of adherents to these minority religions probably decreased sharply in the 1990s because of the wave of emigration from Tajikistan in the early independence period.
