Comparing the suicide risk of transgender people after transitioning to the general population isn’t all that useful. It would be more important to compare the suicide risk of transgender people who transitioned to those who didn’t. I doubt that there is enough data yet to make a good analysis.
I don’t mean to bother @Thorolfr. We’ve talked about the scientific side of things before when I brought up the CDC study.
On this difficult issue, statistical studies show 6 main underlying causes combining together towards such ill-fated regrettable outcome.
The first is ending of a relationship or abandonment by spouse. Then comes substance abuse, loss of ability to work, falling into financial difficulty. When you see someone combining the factors, and verbalizes it, the red flags are all there and anything can easily become a trigger.
The problem is, the transgenders -
by their very nature- are prone to incur in several of the above factors. Certainly, for them relationship will be hard to begin and maintain (abandonment). If they undergo gender reassignment, as with any surgery, that can bring health problems to their ability to work. And well, I do suppose they will have a harder time with financial stability than average folks.
So, in a way, if we verify a deviance in in those rates numerically, it isn’t necessarily because the person is transgender, but because being transgender contributes to the 6 risk factor model. With causes being those exact same 6 risk factors.
[Wikipedia shows that 6 factor model.]
[And I don’t mention the social difficulties and injustices in Durckheim’s classical sense - because that could take attention away from the red flags needing attention.]
