"82.5% of the population are registered as Evangelical Lutheran. They are automatically registered at birth, and few bother to be unregistered. However only about 10% go to church and identify themselves as Christian. A 2006 survey found 29% believe in a God or deity, 23% possibly believe in a higher power but are unsure what it is, 23% do not believe in god and 22% have serious doubts.
Depending on the definition of atheism, Norway is between 26 percent and 71 percent atheist."
