Look at this... a European clinical study that proves transgender is even more rare than my previous findings suggested.

1 in 30 000 change from mtf and 1 in 100 000 change from ftm.
Here's one from the UK.

The way they've presented the numbers seems a bit odd, tho. They start off by saying that 3 in 100 000 present with symptoms of gender dysphoria, while one in 500 present with "some gender variance" w/e that means. However, the ratio is skewed, with nearly 3 times as many males expressing "some variance" than females. They then begin to extrapolate and ask "what if" and throw around misleading guesswork about a figure that gets as high as 1%... with their careful tweaking, ofc.
They also mention the increase in gender variance reported between 1998 and 2011, and use that as evidence that the reporting trend will continue to grow at the same rate, which means (in their minds) that the transgender population will increase from 3 in 100 000 to 1 in 100 sometime very soon.
Just wtf? lol
I would check that against other types of hidden conditions that suddenly grow in prevalence when more people learn about them. My experience has been that they increase double to ten times in prevalence in the general population. Autism is a good example of this phenomenon.
I'm dubious about any claim that a condition will become a thousand times more prevalent. I mean, when was the last time that happened? WWI? The Superflu of 2018? Telling employers to assume that transgendered people will comprise 1% of their workforce is a bit far fetched, imo.
