California spent $24 billion to tackle homelessness over the past five years but didn't consistently track whether the spending actually helped alleviate the problem, according to state audit released Tuesday. An estimated 171,000 people are homeless in California, which amounts to roughly 30% of all of the homeless people in the U.S. Despite the roughly $24 billion spent on homeless and housing programs during the 2018-2023 fiscal years, the problem didn't improve in many cities, according to state auditor's report that attempts to assess how effective the spending has been. the report found that the California Interagency Council on Homelessness, which is responsible for coordinating agencies and allocating resources for homelessness programs, stopped tracking spending on programs and their outcomes in 2021 despite the continuous funding from the state. It also failed to develop a collect and evaluate outcome data of these programs due to the lack of a consistent method.
