"Around the world, including in the UK, there is clear data highlighting disproportionate rates of violence, harassment and hate crimes against trans women.
I want very much to see all the data on this. No doubt there are places where trans women are at great risk of violence, harassment, and hate crimes. But women, in similar places and doing similar things, are also at great risk of violence, harassment, and hate crimes.
The dilemma I have with the data I have seen is that statistics on the most extreme type of violence, murder, do not really support that argument. Transgender people, overall, are not at higher risk of becoming homicide victims than people in general, and where they are killed at higher rates is places where homicide rates are higher overall (South America), and where they are most likely to work in prostitution. The homicide rates of women working as prostitutes in those countries are also very high.
We need to collect good data on all this, and that data should take into account different mitigation rates women and men use, say (eg women are less likely to go out alone after dark). What data is available today is hard to compare because it comes from different sources (often separately for transgender respondents) using different sampling methods and asking different types of questions. Ideally we need both general surveys and police data.
