This is a great narrative, but it turns out that it's not true.

> The overwhelming majority of homeless people surveyed were locals, not migrants from far away: 90 percent lost their last housing in California, and 75 percent lost it in the same county where they were experiencing homelessness. Of the 10 percent who came from elsewhere, 30 percent were born in California. Most of the others had familial or employment ties, or had previously lived in the state.

Again, those are self reported surveys with biased surveyors (who want to push the narrative you believe in) with very weird results. They are basically trying to convince us that the unhoused population is more local than the housed population, sometimes by an order of magnitude, and it really isn’t statistically possible. Something like 75% of the general population are transplants but only 25% of the unhoused population are?

It's unclear to me why this is isn't statistically possible. Could you please explain?

But anyways, this article (paywalled) claims that 48% of California adults were born in the state as of 2022: https://www.sfchronicle.com/projects/2024/california-populat...

In SF and LA those numbers are nowhere near to being 50%. And I guess the wording is important, since many people can crash on a couch for the first few months and then are considered previously housed by the self reporting survey question.

The survey was done across California -- not just SF and LA. Either way, wikipedia claims that 37.7% of SF residents were born in California which is slightly closer to 50% than the 25% figure you quoted (https://en.wikipedia.org/wiki/Demographics_of_San_Francisco#...).

The survey also states that "Most participants (87%) were born in the United States. ... Two-thirds (66%) were born in California."

I still don't understand why the survey is statistically impossible.
