Sure. But that's surely better than your "I think" above that is just based in a hunch.

Correlation may not imply causation, but where there is causation there usually is correlation. So, if there is a rise in homelessness there is likely some factor contributing to that and if a factor is correlated there is a good chance that it's causal. Homelessness may caused by multiple factors but if it's increasing and those factors are mostly remaining static then looking for the one that is also increasing seems like a good bet.

They may be desperate to hire anybody, but not everyone is willing, with good reason, to work 16 hour days with no overtime pay and sub-minimum wage no benefits and work for only part of the year and get paid under the table. only reason it make since for migrants is the low cost/standard of living back home and currency arbitrage where us dollar are worth so much more than their own currency.

I have trouble with a worldview that does not include "the Dakotas" in "bumfucklandia"
