So... is it population density that determines demographics?
What’s your take?
I would say more economic migration. The Midwest's current demos are the leftover of the Great Migration. I imagine if all the steel mills and auto plants had been in Montana and Idaho it would be reversed.
As for the Mexicans, I haven't figured it out yet. It seems kind of random. For instance New York has had a boom during the huge wave of illegal immigration, but they haven't much gone up there.
And they bypass New Mexico almost completely, but many stay in Arizona. Chicago's full of them, but they seem to have completely skipped St. Louis on the way.
And Red State, Blue State, I don't see much of a pattern there. Philadelphia is a sanctuary, but the Phoenix area has always been rough on them, yet more in Phoenix than Philly. Wyoming has a bunch also, and not exactly a Blue State.
I guess it doesn't much matter as the real estate to run to will fast run out. That's why you see people waking up to this issue. They're already commuting 2.5 hours a day. No where left to run.
