Made you look!
But check out this Pew Research Center report (and thanks, Leftover, for the link). There’s a lot of interesting stuff in there, but I was drawn to this:
…this study finds that, globally, women are more devout than men by several standard measures of religious commitment. But the study also reveals a more complex relationship between religion and gender than has been commonly assumed. While women generally are more religious, men display higher levels of religious commitment in some countries and religious groups. And in other contexts, there are few, if any, discernable gender differences in religion.
It’s a lot of stuff, but it is fascinating, particularly Chapter 7, from which the graph above was taken.
