> According to the 2015 U.S. Transgender Survey, 19 percent of all trans people, and 47 percent of black trans women, have engaged in sex work. This does not take place in a vacuum but in the context of pervasive societal discrimination against trans people in general, and trans women of color in particular.

Due to various injustices, sex work is very dangerous. The 19% of trans people who have done sex work are exposed to elevated risk relative to the general population. That 19% is large enough to put a thumb on the scale.

It's like saying men are more likely to die in workplace accidents. Why might this be true? Probably because a lot of men work in coal mines, which are very dangerous. Does that mean I, an office worker, am more likely to be crushed by a falling filing cabinet than the women I work with? No, probably not. The group statistic doesn't tell you everything you need to know about the risk an individual faces.
