To address all of the peer comments at the same time: I don't know. There are places where men dancing is gay-ish and that deters them. That's an easy answer, but it's not enough because very progressive countries don't do much better on this, by my experience. I would agree learning to follow in the very beginning can be easier, so that sounds like maybe men don't remain because their job is harder, but I wouldn't agree with this explanation because I observe fewer men showing up for beginner classes, when they don't know their job might is harder (whether or not it actually is). Maybe men are more asocial on average? I'd be willing to believe that, especially in these times. A comment above yours comments that this isn't true in Turkey, Buenos Aires, and I would add Paris to this list from experience, and then there's the entire continent of Africa we haven't mentioned and I can't really comment on, but what those places have in common is a cultural presence of dance, often a deep connection to dance where families dance together, maybe mom dances when she's cooking, dance isn't something you pick up as an exotic hobby, it's just that thing everyone does, and maybe you decide to do it a bit more than others. Every culture with a lot of cultural dance presence would have a different view on this, I suspect.
