I think this is the first article I've read to use the term "visible homelessness". For many people who live in Seattle, the world "homeless" really means visibly homeless, but for many political activists, the word includes people in shelters or living in the cars or otherwise keeping a low profile while not having a permanent address. I'm no expert but I strongly suspect that the best ways to help the visibly homeless and the not-visibly-homeless are pretty different. But activists are more than willing to conflate the two cases. This particularly arises in the case of affordable housing. Housing may indeed be the primary problem for the not-visibly-homeless. It seems pretty likely though (just based on observation) that the biggest problems for the visibly homeless are mental illness and substance abuse.
I think we'd be better served by not talking past each other and instead make it clear which kind of homeless problem we're talking about at any particular time.
