60/40 Split in "Nones" in 2008 Survey

In this study: http://www.americanreligionsurvey-aris.org/reports/ARIS_Report_2008.pdf
a comprehensive study of religiosity in America has found that among people who don't profess a religion or claim atheism or agnosticism, 60% are male and 40% female, while the percentage of women in Christian denominations is higher than the percentage in the population. On page 11, the study says "These gender patterns correspond with earlier findings that show women to be more religious than men particularly in majority Christian societies."

I wonder if women are more religious in the African societies that promote female 'circumcision' or the Muslim countries that kill women who have been raped "for their honor."
