Religion in Oregon

According to a 2014 report by the Pew Research Center, 31% of Oregon's population was religiously unaffiliated,[a] making it the second-highest percentage after that of Vermont.

[2] Of the Oregon residents identifying as religiously-affiliated, the largest denomination is Roman Catholicism, which makes up approximately 14% of the state's overall population.

[6] All denominations of Protestant accounted for 30%, Church of Jesus Christ of Latter-Day Saints for 5%, Buddhists for 2%, and unaffiliated for 27%, all higher than the national average.

[10] While Oregon has higher than average rates of evangelical Christianity and Latter-Day Saints compared to mainline or orthodox sects of Christianity, Judaism and Islam, it does have a slightly higher percentage of Buddhists regardless of sect,[11] and is part of overall growth in Buddhists not of ethnically Asian origin in the West.

[12] Oregon also contains the largest community of Russian Old Believers to be found in the United States (nearly 10,000 as of 2002),[13] due to a relatively large immigrant population from areas where the church originated.

[17] According to a 2017 study from the Public Religion Research Institute, the percentage of unaffiliated individuals was 36% (second-highest to Vermont, which was reported as 41% religiously-unaffiliated).
