The religious world is growing, fast

Pew's study on religion around the world shows significant generation gaps, with younger people less likely to consider religion a very important part of their lives.

The flipside: Populations are growing fastest in countries that tend to be very religious (particularly in sub-Saharan Africa) and shrinking in some of the world’s least religious countries (Japan, Eastern Europe). Thus, the authors write, “it is not necessarily the case that the world’s population, overall, is becoming less religious.”
