Most Norwegians are registered at baptism as members of the Church of Norway; many remain in the state church to be able to use services such as baptism, confirmation, marriage and burial, rites which have strong cultural standing in Norway. About 79.2% of Norwegians were members of the Church of Norway as of January 1, 2010. However, only 20% of Norwegians say that religion occupies an important place in their life (according to a Gallup poll in 2009), the fourth-lowest such percentage in the world (only Estonia, Sweden and Denmark are lower). In the early 1990s, it was estimated that between 4.7% – 5.3% of Norwegians attended church on a weekly basis. This figure has dropped to about 2% – the lowest such percentage in Europe – according to 2009 and 2010 data
There are, by November 2011, about 98,000 registered Catholics in Norway. But there are also lots of Catholics who aren't registered with their personal identification number; the real number is probably about 230,000 Catholics, 70% of whom were born abroad.
Annuario Pontificio 2011 use a number of 229,652 Catholics. That constitutes about 5% of the population, making Norway the most Catholic country in Northern Europe.
In 2010, 10% of the population was religiously unaffiliated, while another 9% (431 000 people), were members of religious and life stance communities outside the Church of Norway. Other Christian denominations total about 4.9% of the population, the largest of which is the Catholic Church, with 83,000 members. Others include Pentecostals (39,600), the Evangelical Lutheran Free Church of Norway (19,600), Methodists (11,000), Baptists (9,900), Orthodox (9,900) Brunstad Christian Church (6,800), 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 religions comprise less than 1% each, including 4,000 members in the Church of Jesus Christ of Latter-day
