Ukraine is an overwhelmingly Orthodox Christian nation, with nearly eight-in-ten adults (78%) identifying as Orthodox (compared with 71% in Russia), according to a 2015 Pew Research Center survey of much of the country (some contested areas in eastern Ukraine were not surveyed). This is up from 39% who said they were Orthodox Christian in 1991 – the year the officially atheist Soviet Union collapsed and Ukraine gained its independence. With roughly 35 million Orthodox Christians, Ukraine now has the third-largest Orthodox population in the world, after Russia and Ethiopia.
