One point that is made in the article is definitely true, that being that the vast majority of those that attend women's games are over 50 and under 10. Pretty much the only members of that middle demographic that are in attendance are there with their under-10 kids.
Why are the seniors there? One reason is probably that it's an affordable sport to watch.
Why the absence of the huge age group in the middle? I believe that it's because women students and young adults are just not as interested in watching sports as their male counterparts. So, if they go to games at all, which they do far more than when I was young, it's to the men's games, where their male dates and husband prefer to go.
