My understanding is that "living in the same county as your last housing" can mean that you moved to California with enough money to rent a room for a month before running out. Though, I have seen many other surveys that do indicate that most unhoused individuals have lived in the area for an extended period before factors forced them out (https://www.nytimes.com/2019/11/06/us/homeless-population.ht...).

In any event, I feel that metric used by UCSF is really not a good one to the point where it's almost dishonest. It's not hard to come up with questions that do a better job at trying to answer whether CA is burdened by individuals moving from out-of-state to make use of more generous social programs and/or lax drug policy.
