Doubting these reports is just highlighting your own naivety and commitment to a narrative that is fraudulent.
In fact I would go so far as to say, when you have access to robust, widespread information and continue to poo-hoo it - this is verging on conspiracy theory territory, isn't it?
These are not backyard surveys conducted by some crackpot fantasist, these are very rigorously studies / surveys conducted by large teams of professional from multiple disciplines working with tens of thousands / hundreds of thousands of people to establish how crime trends are working.
You can knock yourselves out undermining them; I would expect nothing else. I am sure there are men out there too mocking the surveys highlighting domestic violence against women ' O I wouldn't describe THAT as violent!... O she perceived that as abusive did she? - well that was just her perception, it's not really abuse though is it?....O well, what people don't know is how she started it in the first place...', they don't include that in the figures, do they?)
Of course, knock yourselves out undermining the victims of violence, unfortunately I've come to expect little else from these boards where some people who purport to be challenging the patriarchy appear to spend most of their time aping the patriarchy.
And what some people are essentially saying in this thread is that it is impossible to study this as an area due to figures involved. But I guess that suits a lot of people that just never want to acknowledge the truth - how fortunate to be able to repeat 'Oh, the figures are just too small, we will never be able to really know - we might as well just not try to find out, eh?!'
Of course, this is not true; data found on small numbers of participants can achieve statistical significance, and they did achieve statistical significance for differences in rates of violent victimisation between trans and non-trans people in this work.
Obviously people here have clearly have not studied statistics and are unfamiliar with how information is reported (and also how this can vary between journals that place more emphasis on the usefulness of confidence intervals, for example). You will see, in the link that @CharlieParley has posted, how the P values in the study have been cited - they are detailed for those areas where statistical significance was not achieved, but NOT specified for those differences looked at where statistical significance was achieved (this is possibly a requirement of the journal the results are posted in): eg.
Transgender people experienced violence at a rate of 86.2 victimizations per 1000 persons compared with 21.7 per 1000 persons among cisgender people (Figure 1a; odds ratio [OR] = 4.24; 90% confidence interval [CI] = 1.49, 7.00). These differences remained for men and women. Transgender women and men had higher rates of violent victimization (86.1 and 107.5 per 1000 persons, respectively) than did cisgender women (23.7 per 1000 persons; OR= 3.88; 90% CI = 0, 8.55) and cisgender men (19.8 per 1000 persons; OR= 5.98, 90% CI = 2.09, 9.87), but there were no differences between transgender men and women (Δ = 21.4; SE = 68.7; P = .76
