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, 7.7% 'Christian' with no declared denominational affiliation, 9.4% Ukrainian Byzantine Rite Catholics, 2.2% Protestants and 0.8% Latin Rite Catholics, 2.5 % Islam, Judaism was 0.4%; while a small percentage follow Hinduism, Buddhism and Paganism. 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.
As of 2018, Christianity was particularly strong in westernmost Ukrainian regions, where most Greek Catholics lived. In central, southern and eastern regions, Christians constitute a smaller proportion of the total population, particularly low in the easternmost region of Donbas.
