The gender gap in worship might not have been a great thing, but some religious leaders might prefer that to what's happening now.
The share of women attending religious services each week at a church, synagogue or mosque — long much higher than men's — is narrowing. It dropped from 36 percent in 1974 to 28 percent in 2012, according to a new study by the Pew Research Center.
During the same period, the share of men dropped from 26 percent to 22 percent.
Put another way, a 10-point gap in attendance narrowed to 6 points.
So what's going on?
Researchers checked out a couple theories.
One was that as the number of women working full time has soared — one in three in the 1970s compared with one in two today — work time took a bite out of time at church, synagogue or mosque.
But the biggest influx of women into the workforce occurred in 1970s and early 1980s, a period when the gender gap in church attendance was actually widening — reaching 13 points.
