Where I directly live, nothing, because I'm pretty sure there aren't homeless people in the remote area we live. I don't even see the few empty farms with signs of squatters here. We live rural enough that anyone homeless would head to the nearest city because they would die of exposure here and there are no services close by.
That isn't to say there isn't some extreme poverty in this rural area. Some of the places people live would easily be condemned if there were zoning and enforcement in this area. Many would be better off living in a barn, the structures are so bad.
The nearest city (pop. 50,000) has quite a bit going on for the size and the relative increased poverty of the area.
There are several homeless shelters, a domestic violence shelter, a host of food pantries (many many food pantries), and many, many churches with various programs from free hot meals, to clothes closets, to counseling services.
There are 'stuff the bus' back to school supply drives in every town and rural school district, Salvation Army giving trees (and several other charities that do the same thing during the holidays and back to school time), there is a 'store' for kids at or below the poverty line to go and shop for new and like new school clothing, choosing the things they need. Kids are referred by school administration when they see the needs.
There are several organizations that do a big promotional "sleep out for the homeless" every fall and collect money and goods for the homeless. There are warming centers and cooling centers set up in the heart of downtown during the worst weather.
There are a few small organizations that canvas the downtown area on a regular basis with free food and blankets for those living on the streets.
Again, I'm kind of amazed that for a town the size it is, and the way over the last several decades, has lost most of it's industry and tax base, it has so much help. Most of it I hear about is private charity based. I'm sure there are some government funded or aided things too, I just don't really know what they are.
