How the heck do these stats make sense? Like far more younger men than women are single? Shouldn't it be about equal? I mean as most people are in hetero monogamous relationships. I don't think polyamorous and same sex relationships would explain the huge disparities. Like 51% of young men vs 32% of young women single? Something tells me it's to do with sampling. What other explanations could there be?
