What is Swedens dominant religion?

Answer 1

It is 87 percent Lutheran.

Answer 2

At the end of 2007, 74% of Swedes belong to the Church of Sweden (Lutheran), this number has been decreasing by about 1% on a yearly basis for the last two decades, and Church of Sweden services are sparsely attended (hovering in the single digit percentages of the population). The reason for the large number of inactive members is partly that until 1996, children became members automatically at birth if at least one of the parents was a member. Since 1996, all children that are christened become members. Some 275,000 Swedes are today members of various free churches (where congregation attendance is much higher), and, in addition, Immigration has meant that there are now some 92,000 Roman Catholics and 100,000 Eastern Orthodox Christians living in Sweden. Because of immigration, Sweden also has a significant Muslim population. Almost half a million are Muslims by tradition, but approximately 5% (25,000) of these actively practise Islam (in the sense of attending Friday prayer and praying five times a day).
