Quote from "Scandanavian Nonbelievers, Which Is Not to Say Atheists "

Anyone who has paid attention knows that Denmark and Sweden are among the least religious nations in the world. Polls asking about belief in God, the importance of religion in people’s lives, belief in life after death or church attendance consistently bear this out.

It is also well known that in various rankings of nations by life expectancy, child welfare, literacy, schooling, economic equality, standard of living and competitiveness, Denmark and Sweden stand in the first tier.
