Religious involvement by sex and ethnicity: Steve Sailer suggested I post on the gender differences in spirituality and religious attendance. Let's begin with the latter. Here are mean scores broken out by ethnic group and sex:
American Indians 3.21
American Indians 4.23
While the ranks are similar for the two sexes, Irish men rank a little higher than the women, while Scottish and English women rank higher than their male counterparts. Dragging your partner to church might be one factor that makes men and women similar. Another is selecting someone like yourself for a partner.
Notice how the least religious women (Italians) are more churchgoing than the most religious men (Blacks).
