Well, actually, Europe is the main exception to the rest of the world. America is in-line with most of Africa, the Middle East, Asia, India, and South America in that religion still plays a major role in everyday life. In fact, religions are growing, not shrinking, worldwide.

Perhaps I should have been more clear, America is the exception of the wealthy countries that can afford extensive education. What might have previously been commonly called first-world.

See how the US is an outlier?

The thing is, the concept of religion as a distinct, separate part of culture is basically a Western concept itself - and one that many scholars don't find to be very solid. Take Japan for example: Shintoism and Buddhism are very woven into the culture of modern Japan. Rituals, shrines, and other associated practices are quite prevalent and most of the population interacts with them on a regular basis. Yet your link lists Japan as being the second-least religious country, after China, which also has a number of beliefs that essentially qualify as 'religious' in nature.

In the Western world, the concept of humanist, egalitarian democracy is more-or-less an extension of certain Christian ethical beliefs that preceded it, so again, this definition of 'not-religious' is itself pretty problematic.
