> Isn’t this based on self-answered surveys and not hard verifiable information to establish residency?

True, though collecting hard verifiable proof of prior residency from homeless folks seems beyond what can be expected from a one-day citywide survey. :)

If you know of a survey that did collect that information, I'd certainly be interested in the results.

> The homeless and activists/nonprofits advocating on their behalf have an incentive to make it look like they’re mostly local.

I suppose a high out-of-county population might make locals stingier, but getting caught providing bad data also seems like a pretty bad outcome for any of the local non-profits that helped conduct the survey.
