I'm curious about the ratio of those unwell folks who are native to the area compared to those who are transplants. I can certainly imagine a 'homeless pipeline' where the children of the parents who get priced out of housing end up doing drugs on the street, but I also know about bussing the homeless and homeless moving to SF because they don't want to deal with a serious winter.
