I am not surprised by this, TRAs do not want accurate data collection as it potentially undermines their arguments. I suspect there was an element of rebelling and TW stating female for sex.
It shows why the NHS removing the words women and girls from medical conditions and symptoms is such a bad idea. As has been said time and again, it will impact women who have English as a second language and those with poor comprehension.
I had always hoped the census would give us stats that can be used to fight for single sex spaces. For example, It’s hard to justify making all toilets in a building unisex if only 0.2% of the population are transgender.
I am disappointed as the census results are being released they are showing such contradictory information.
I have always had respect for the ONS, this has disappointed me but more importantly has worrying implications for everyone.
