This passage for example. Houston can only achieve permanent placement if it actually has homes to place people in. SF is just rearranging deck chairs on the titanic because it has no where to put people and they're in and out of shelters. (Vancouver has the same issue)
> Houston houses people first, then closes encampment sites permanently. San Francisco deploys enforcement first, achieves temporary displacement, and watches areas refill. Houston tracks every person from intake through permanent placement. San Francisco can’t determine if anyone is being permanently housed at all.
Beyond better outcomes around creating new affordable housing if Houston and Dallas are also doing a also better job at keeping rents low and maintaining existing affordable housing that will also prevent people from becoming homeless in the first place.
A recent study in Vancouver found that one of the most significant single causes of homelessness (20%) was people simply running out of money and being evicted. The direct cause of this is high rents. So any city that is building more housing in general, and not demolishing existing affordable rental is going to be doing a better job in this category at reducing homelessness.
