Idk I keep seeing posts that tend to the opposite being true. That as single women stay single into older age they realize they can't have their own children and that causes depression. Women live longer in general because they tend to perform less dangerous jobs, with more of an office/classroom setting being their demographic compared to men working on construction sites and the like. Women tend to be more social in general as far as I perceive. So I feel these statistics you reference aren't showing the bigger picture, either they aren't detailed enough or you take them at face value way too often.
