I would be interested to compare this to homicide rates. Because I remember reading that when no fault divorce was allowed male lifespan increased.

I also think it's too early to really look at these rates. Of course many women would be happy they weren't destitute when they got married during a time when women couldn't have bank accounts. Of course men would feel put out when they were used to having everything handled by their wife and existed during a time where joint custody was not so common.

I'd like to see these studies again in 20 or so years when most people surveyed got married out of commitment instead of life necessity.
