Women who are alert and industrious tend to stay busy, regardless of where they are. They have an inner drive.

I'm not denying that. I'm questioning the accuracy of such statistics when dictating the levels of marital stability of single-income in relative to dual-income households.
It's been a shift.
Used to be the other way around, but the middle-class women who used to be homemakers usually work now, and they took their marital stability into the working demographic.
The statistics make sense, though. A woman whose whole existence is keeping a home and raising children will come to be dissatisfied, especially as the kids grow up. A part-time side gig or other similar projects help give a sense of self that can endure changes in a growing and maturing family.
