This seems to be something people don’t always give second thought to. When people talk about the homeless, the first things thought about are images of people on busy city streets in rusty clothes waiting around near allies. In there, the answer is quite static, because it can be I guess. But if that’s the case, change the setting and that changes too. In the places where I’ve lived, people often needed that mapped out. Where are they known in your rural locales?
You don’t know what you are talking about. There are absolutely homeless people in rural areas. While you might not see people begging on the street downtown, there are absolutely people living in their car, camping, or sleeping under a bridge.
I grew up in a very small rural town of 2500 nowhere near a city. There were absolutely homeless people. You seem to have a view of homeless people that only exists in the movies.
