Why does religion continue to grow?

[abaris]

So, Steve, let me break it down for you:

France, between 2005 and 2012, a decline of 21 percent in religiosity
Canada, a decline of 12 percent
The USA, 13 percent
Germany, 9 percent.
Austria, 10 percent.

That's from page 6 of the report, covering the top ten nations with a decline in religiosity. Within a timespan of 7 years.

Page 13 might also be of interest, since it covers national income and religiosity.
