What percentage of Mensas are females?

[El Sordo]

The only Mensa members that I've ever met have been females.

I've always found that a bit amusing.

What percentage of Mensas are females?

The latest published figures for American Mensa is 35% women, 65% men (although I'd question the omission of an "indeterminate" category). From my experience at Mensa gatherings, I'd say Houston fits that range.
