I frequently see stats bandied about and claims made on social media that trans people are much more likely to be the victim of violent assault than 'cis' people. For example, here is Helen Webberley claiming that "...trans people are 4 x more likely to be victim of violent assault than cisgender people, just because of their identity". https://www.reddit.com/r/transgenderUK/comments/1natr6o/graham_linehan_arrest_setting_piers_morgan/
Does anyone know where they are getting these stats from, as I rarely see a source referenced.
