Medical and voting records generally ask for sex, not gender. It would be nice if the two concepts would stop being confused.

I agree. That said, using actual gender rather than assigned sex only serves to identify people more uniquely. I wonder if that would have an appreciable effect on the stats or if it would fall within error bars.

You'd have to have a pretty long dropdown menu in the data-mining centers for all the genders people self-identify these days. Some people might be uniquely identifiable on that value alone.

or when someone comes up with a newer more politically correct term!

I prefer writing Sex: Yes, please
