From the article:
"As of 2015, the state can just about declare victory: The population of chronically homeless people has dropped by 91 percent."
...
"In fact, Utah still has a substantial homeless problem. The overall homeless population is around 14,000."
"The chronically homeless, on the other hand, are a subset of the homeless population that is often the most vulnerable. These are people who have been living on the streets for more than a year, or four times in the past three years, and who have a "disabling condition" that might include serious mental illness, an addiction or a physical disability or illness."
...
"By implementing a model known as Housing First, Utah has reduced that number from nearly 2,000 people in 2005, to fewer than 200 now."
