“We have the resources, as a society, to prevent and end homelessness. And the knowledge.” Beth Shinn discusses the Family Options Study, which found that long-term housing subsidies, like housing vouchers, led to much better outcomes at similar cost compared to rapid rehousing, transitional housing, and “usual care.”

In Los Angeles County, unhoused people living in cars, trucks, and RVs outnumber those in tents and makeshift shelters by 50%, yet vehicular homelessness receives relatively little attention. Many cities don’t even measure or report on it — at least not yet. The Lewis Center’s Madeline Brozen joins to discuss her research on the distinct demographics and experiences of unhoused people living out of their vehicles, and the promise of safe parking programs to support the transition back into stable housing.

Many people think they know about the lives of people experiencing homelessness, but those perceptions are often based on anecdote. Margot Kushel, MD joins us to talk about her work on the largest representative study of homelessness since the 1990s, and what it says about who experiences homelessness, why they become homeless, their experiences while living without housing, and barriers to re-entering stable housing.
