The UK still has to play catch up in conducting research with the scale, scope and rigour of this kind, and until it does, of course it is harder to show what is happening with trans victims of crime.
The Crime Survey for England and Wales (formerly the British Crime Survey) is broadly comparable in its methodology and has been conducted since 1982. However, when it comes to crime and social factors, as pointed out already, it isn't just a common language that divides the UK and US.
Out of interest, what factors do you think might be at work behind the crime victim figures for the US, where freedom of speech is paramount and minorities, especially trans people, are frequently vilified and maligned?
A lack of medical and social security safety nets and the concomitant higher level of transgender individuals active as prostitutes is likely to be a bigger factor than free speech protections, I suspect. And levels of violent crime are much higher in the US more generally.
