Wikipedia: (Total population is approx 5 million)

Among non-Christian religions, Islam is the largest with the population of about 150,000.[114] It is practiced mainly by Somali, Arab, Albanian, and Turkish immigrants, as well as Norwegians of Pakistani descent.

The article also notes that although the Church of Norway is the official state religion which includes 79% of the population, Norwegians are among the least religiously adherent people in the world, 20% consider their religious faith important to them and under 5% attend church weekly.

Even under present circumstances, I think I could enjoy spending some time there...
