Ignoring the same old same old merails,
Kalula, since transwomen are recorded as women in crime statistics, I don't really see how it is possible to find out whether they are more likely than natal women, also recorded as women, to be assaulted.
If it is based purely on the word of the victims, it's still hard to quantify. A lot depends on the definition of assault: is having your bum pinched assault? How about a wolf-whistle? and so on. And if a hate-crime is recorded as having occurred even while it is not recorded as a crime, where does that leave the stats? Is calling a woman a filthy slut as much a hate-crime as calling a transgender woman a pig in a wig? My bet is that a far larger percentage of women get called vile or just offensive names than transwomen.
The link he gave you seems to be to an American site, so it's hard for me, in England, to see what it has to do with UK crime rates any more than say gun-crime stats in America have to do with the rate of gun-crimes in the UK.
I do find "In the NCAVP 2009 report on hate violence, 50 percent of people who died in violent hate crimes against lesbian, gay, bisexual, transgender, and queer (LGBTQ) people were transgender women; the other half were male, many of whom were gender non-conforming." somewhat hard to credit: it made me wonder, "what, not a single lesbian?" How many of them were there? I mean, two trans women and two males is shocking, but two hundred of each would be even more so. No numbers, only percentages, makes it very hard to judge the actual extent of anything.
