Religious affiliation

Official religious affiliation in Norway (31 December 2019):

According to the 2010 Eurobarometer Poll, 22% of Norwegian citizens responded that "they believe there is a God", 44% responded that "they believe there is some sort of spirit or life force" and 29% responded that "they don't believe there is any sort of spirit, God or life force". Five per cent gave no response. In the early 1990s, studies estimated that between 4.7% and 5.3% of Norwegians attended church on a weekly basis. This figure has dropped to about 2%.

In 2010, 10% of the population was religiously unaffiliated, while another 9% were members of religious communities outside the Church of Norway. Other Christian denominations total about 4.9% of the population, the largest of which is the Roman Catholic Church, with 83,000 members, according to 2009 government statistics. The Aftenposten (Evening Post) in October 2012 reported there were about 115,234 registered Roman Catholics in Norway; the reporter estimated that the total number of people with a Roman Catholic background may be 170,000–200,000 or higher.

Others include Pentecostals (39,600), the Evangelical Lutheran Free Church of Norway (19,600), the United Methodist Church in Norway (11,000), Baptists (9,900), Eastern Orthodox (9,900), Brunstad Christian Church (6,800), Seventh-day Adventists (5,100), Assyrians and Chaldeans, and others. The Swedish, Finnish and Icelandic Lutheran congregations in Norway have about 27,500 members in total. Other Christian denominations comprise less than 1% each, including 4,000 members in the Church of Jesus Christ of Latter-day Saints and 12,000 Jehovah's Witnesses. Among non-Christian religions, Islam is the largest, with 166,861 registered members (2018), and probably fewer than 200,000 in total.

Other religions comprise less than 1% each, including 819 adherents of Judaism. Indian immigrants introduced Hinduism to Norway, which in 2011 has slightly more than 5,900 adherents, or 1% of non-Lutheran Norwegians. Sikhism has approximately 3,000 adherents, with most living in Oslo, which has two gurdwaras. Drammen also has a sizeable population of Sikhs; the largest gurdwara in north Europe was built in Lier. There are eleven Buddhist organisations, grouped under the Buddhistforbundet organisation, with slightly over 14,000 members, which make up 0.2% of the population. The Baháʼí Faith religion has slightly more than 1,000 adherents. Around 1.7% (84,500) of Norwegians belong to the secular Norwegian Humanist Association.

From 2006 to 2011, the fastest-growing religious communities in Norway were Eastern Orthodox Christianity and Oriental Orthodox Christianity, which grew in membership by 80%; however, their share of the total population remains small, at 0.2%. It is associated with the immigration from Eritrea and Ethiopia, and to a lesser extent from Central and Eastern European and Middle Eastern countries. Other fast-growing religions were Roman Catholicism (78.7%), Hinduism (59.6%), Islam (48.1%), and Buddhism (46.7%).
