My dude I saw homeless people in towns with a population of 4000 in Mississippi. This is just false.
Your anecdote is just an anecdote.

When I checked the box to view percentages, homelessness seems pretty consistent with the major outliers being CA and NY. CA says 26% and NY says 16%, with most everyone else on low single digits. I'm not entirely sure what those numbers mean, though.
