A Los Angeles County program that seeks out people at high risk of homelessness and tries to help them stay off the streets and out of shelters is showing early signs of success, according to a study published Thursday.

Launched in 2021, the county's Homelessness Prevention Unit uses artificial intelligence to comb through vast troves of government data, looking for signs that someone is likely to fall into homelessness. Some of the risk factors include frequent hospitalizations, psychiatric holds, welfare program enrollment and past incarceration.
