Religion in Ukraine
Religion in Ukraine is diverse, with a majority of the population adhering to Christianity. A 2018 survey conducted by the Razumkov Centre found that 71.7% of the population declared themselves believers. About 67.3% of the population declared adherence to one or another strand of Orthodox Christianity (28.7% of the Kiev Patriarchate, 23.4% state simply 'Orthodox' with no declaration as to which Patriarchate they belong to, 12.8% of the Moscow Patriarchate, 0.3% Ukrainian Autocephalous Orthodox Church, and 1.9% other types of Orthodoxy), 7.7% 'Christian' with no declared denominational affiliation, 9.4% Ukrainian Byzantine Rite Catholics, 2.2% Protestants and 0.8% Latin Rite Catholics. Judaism was the religion of the 0.4%; while Buddhism, Paganism (Rodnovery), and Hinduism were each the religions of 0.1% of the population. A further 11.0% declared themselves non-religious or unaffiliated. According to the surveys conducted by Razumkov in the 2000s and early 2010s, such proportions have remained relatively constant throughout the last decade, while the proportion of believers overall has decreased from 76% in 2014 to 70% in 2016 and 72% in 2018.

Russia
Traced back to the Christianization of Kievan Rus' in the 10th century, Russian Orthodoxy is the dominant religion in the country; smaller Christian denominations such as Catholics, Armenian Gregorians and various Protestant churches also exist. The Russian Orthodox Church was the country's state religion prior to the Revolution and remains the largest religious body in the country. An estimated 95% of the registered Orthodox parishes belong to the Russian Orthodox Church while there are a number of smaller Orthodox churches. However, the vast majority of Orthodox believers do not attend church on a regular basis. Easter is the most popular religious holiday in Russia, celebrated by a large segment of the Russian population, including large numbers of those who are non-religious. More than three-quarters of the Russian population celebrate Easter by making traditional Easter cakes, coloured eggs and paskha.
