I refer you to the answer I gave to your questions WQ89362 and WQ89363 which included information on where data can be found on the number of people in Wales who identified in the 2021 Census with a gender identity different to their sex registered at birth.
The number of people in Wales who have changed their legal sex with a gender Recognition Certificate is unavailable. Gender Recognition Certificates are issued by the Gender Recognition Panel which is a branch of HM Courts and Tribunals Service, and statistics on the number of certificates issued by the panel in the service’s quarterly Tribunal Statistics Publication do not include a breakdown for Wales.
