Last I checked it's about 1% of the population is trans, numbers are going up among youth, we're definitely underrepresented. Also personally it irritates me that most trans roles are for things specifically about trans and queer people or their entire character identity somehow becomes the fact they're trans. Would be nice to have more "this is a show that has nothing to do with queerness also one of the people is trans, doesn't come up in any big way". There have been a few but it's rare
