I've spoken to people and read articles where they moved to California to stay with a friend temporarily and try to find work or a similar scenario, it didn't work out and they ended up homeless. If your last address was prison in California, your last address makes you "a Californian."
Those stats tend to be self reported. They tend to try to frame the local homeless as members of the community in which they are currently homeless in order to try to convince people to see them as human beings deserving help and compassion because it's already far too common for cops to drive them to the edge of town and dump them or stick them on a bus to elsewhere.
It's illegal to dump homeless people that way but it's common knowledge that it happens. And it's a known thing some hospitals and such in other states release people, stick them on a bus and send them to California.
I spent nearly six years homeless. I traveled to California as a homeless person to camp there. I left California to get back into housing after all attempts to get into housing in California failed, even though I repeatedly relocated to someplace cheaper within California to try to arrange it.
I have talked to homeless people in person or online for years. I know for a fact other homeless people choose to physically relocate to more temperate, drier climes to survive it. You can go on reddit and find questions about "where to go" as a homeless person. Warmer and dryer are two frequent criteria sought.
I've participated in the planning stages of an annual point in time count. I'm familiar with the enormous challenges involved in getting useful data on a population that does its best to remain invisible.
The highly obvious homeless are the tip of the iceberg. There are far more homeless in stealth mode hiding it from their employer or their college, sleeping in a vehicle or couch surfing or living in situations not intended to be permanent housing, such as hotels.
I'm confident that my characterization of the situation is accurate. And that the people publishing data on homeless populations rarely have good data to begin with and then routinely spin it to serve a political agenda of trying to get some compassion and sympathy for people instead of more abuse.
I don't want that. I want housing solutions, not a pity party, and I've been pursuing education and doing personal research etc for decades to try to serve that goal.
So I guess we can agree to disagree because that's a big fat NO from me, sorry.
