Seattle's 2019 point in time counts says 84% local, 11% in-state, 4% came from out of state. San Francisco has similar numbers. Seattle excluded this data from their most recent report. Possibly because they out of state numbers have been going up, and it is harder to raise money and sympathy for non-local homeless? But even if you allow for that, it is huge majority local.
