@cute_weeds @garbados IIRC about one third of those who participated in the US Trans Survey identified as nonbinary in some form.
I forget the total sample size.
WPATH (who makes the rules, basically) is definitely adding a chapter on nonbinary folks in their Standards of Care, but I have no idea if they're putting us in the "trans" umbrella.
Things are definitely changing; developers *need* to catch up, and quick.
