Homeless people in California are already a vulnerable group, often struggling with poor health, trauma and deep poverty before they lose their housing, according to a new study on adult homelessness. The study attempts to capture a comprehensive picture of how people become homeless in California, and what impeded their efforts at finding permanent housing. Researchers at the UCSF Benioff Homelessness and Housing Initiative hope that the study will strengthen public support for policies that focus on offering housing and emergency rental assistance—rather than policies emphasizing punishment or stigma. “People are homeless because their rent is too high. And their options are too few. And they have no cushion,” said Margot Kushel, MD, UCSF's BHHI director and lead investigator. “And it really makes you wonder how different things would look if we could solve that underlying problem.”

California’s homeless population is predominantly made up of people who lived in the state before losing their housing, with nearly half older than 50 and a disproportionate number who are Black and indigenous, according to a new statewide study. “We have got to bring housing costs down, and we’ve got to bring incomes up,” said Margot Kushel, MD, the study’s principal investigator and director of UCSF’s Benioff Homelessness and Housing Initiative. “We need to solve the fundamental problem—the rent is just too high.”

Conducted by the UCSF Benioff Homelessness and Housing Initiative, the California Statewide Study of People Experiencing Homelessness (CASPEH) is the largest representative study of homelessness in the United States since the mid-1990s. The study provides a comprehensive look at the causes and consequences of homelessness in California and recommends policy changes to shape programs in response.

The University of California, San Francisco Benioff Homelessness and Housing Initiative (BHHI) has released the largest representative study of homelessness in the United States since the mid-1990s, providing a comprehensive look at the causes and consequences of homelessness in California and recommending policy changes to shape programs in response. The California Statewide Study of People Experiencing Homelessness (CASPEH) used surveys and in-depth interviews to develop a clear portrait of homelessness in California, where 30% of the nation’s homeless population and half of the unsheltered population live.
