At the risk of repeating stuff already stated on a few other threads (apologies to those who have read this before):
There are two types of transwomen and they are basically two completely different kinds of people, and do not overlap at all.
One group is the "androphilic" (attracted to men) transwomen--the ones who come from the same group as gay men. The best way to think of these is as ultra-femme gay guys who have made the decision to live as women, with almost all living full time as a woman by the age of 20. These boys were very feminine-presenting in habits and interests from early childhood. The decision to live as a TW rather than a gay man is complex, but ability to "pass" appears to be one factor, as is background/culture/ethnicity. If you live in a cultural milieu where men are bullied for being gay or not being macho, it is hard to carve out a niche for yourself as a gay man, so you are more likely to choose to live as a woman. That's why androphilic transwomen in the US are disproportionately likely to be black or hispanic. Many leave home/drop out of school and end up homeless or in insecure situations, selling sex or engaging in petty crime in order to survive. Others form relationships with violent men who abuse them, kick them about, sometimes kill them. These TW are genuinely vulnerable people.
The other groupand in the UK, US etc. they make up around 2/3 of all TWare the gynephilic transwomen. They are pretty much exclusively into women. They have no consistent history of presenting as feminine or preferring female friends, but do have a history of auto-erotic cross-dressing in most cases. This is a phenomenon (sometimes called autogynephilia) in which a heterosexual man "projects" his desire for the female form onto his own body--so he will put female clothing or undies on, look at himself, masturbate and fantasize. It's odd, but commoner than you'd imagine. Most cross-dressers never go beyond dressing, but a minority decide to actually live as women full time. Gynephilic (or AGP) transwomen are a Western phenomenon, tend to come more often from highly educated backgrounds, very often have careers in STEM, tech, engineering, and are usually white.
The first group of TW are indeed at high risk of being murdered--they are living in an insecure way and are selling sex to often violent men and often in violent relationships with violent men too.
The second group? No, quite honestly. They are not living on the streets since these TWs invariably establish settled careers and reputations BEFORE they transition, and tend to be better-off-than-average people. They are not selling sex to men. They are also not in relationships with men.
Thing is, though, most of the angry transactivitsts you'll see ranting on Twitter about how they are going to be literally murdered by TERFs etc. are from the second group, not the first group! Most transactivism is from gynephilic transwomen, in part because their transition is so public and they don't "pass" well, so they have no choice other than to make a big thing about being trans. Most of the first group, the androphilic transwomen, pass pretty well and mostly just keep their heads down.
