This is just a memo thread to make the data easy to find.
The FWS Supreme Court ruling covered ONLY those with a GRC.
All individuals without a GRC had been ruled to have no rights other than as their birth sex (ie no self ID) at the earlier hearing.
So How many people have a GRC in the UK ?
This is the master record of GRC's issued
https://www.gov.uk/government/statistics/tribunals-statistics-quarterly-july-to-september-2025
As at September 2025 a total of 10,256 GRCs have ever been issued
of which 6,514 were to those born male.
We have no idea how many GRC holders are alive
but as 2,143 of those holders were born before 1960 its a reasonable guess that a fair few have since died.
So, the number of men affected by the FWS supreme court ruling was likely around 6,000
out of a national male population of over 33,000,000
