Seems to be a slow decline in the numbers since the bush years although nothing about it is good. In fact, it's criminal that this problem exists in arguably the greatest country in the world.
Since 2007, chronic homelessness among
individuals has declined by 25 percent (or
31,240), from 123,833 to 92,593 people. The
number of sheltered chronically homeless
individuals declined by nearly 30 percent, or
12,350 people. The number of unsheltered
chronically homeless individuals declined by
23 percent or 18,890 people.
