The census informs loads of public policy and spending.
If it's wonky then there is a real long term knock on effect.
It's not trivial.
I can't believe the fucking ONS of all people are doing this.
What the hell is wrong with sex at birth/ are you trans how do you ID?
That will be really useful info for those looking into needs and studying about the trans community.
Under this idea. Say you've changed your passport (easily done) or your gas bill (?) or whatever. And you were male at birth.
You say you are female and not trans.
So that's a stat lost to those interested in the number of trans people and trying to understand their needs.
