The California Statewide Study on People Experiencing Homelessness researchers included people who were formerly or are currently experiencing homelessness. In this op-ed, Claudine Sipili, one of the Lived Expertise Advisory Board co-chairs, writes about the landmark study and her experience participating with the project. She writes, "Throughout the study, the board members’ guidance helped create a safe and dignified space for survey participants to share their experiences openly. By involving individuals with lived experience, we gained deeper insights into the complexities of homelessness."

As a board member of the UCSF Benioff Homelessness and Housing Initiative (BHHI) Lived Expertise Advisory Board that played a major role in the design and implementation of the California Statewide Study of People Experiencing Homelessness, my participation on the project was deeply influenced by my personal experience of homelessness. Having faced the challenges and uncertainties associated with housing instability firsthand, I have dedicated myself to making a positive impact and working towards finding lasting solutions for those facing similar struggles.

Our Encampment Prioritization Tool is designed to help communities navigate the complex landscape of homelessness. By balancing the urgent need to address encampments with the chronic shortage of housing and shelter resources, along with health and safety considerations, this tool guides stakeholders in making informed decisions. It ensures that actions prioritize housing and shelter placements over displacement, aligning with broader systemic reforms to effectively manage and resolve encampments.

Encampment resolution is a strategic approach focused on connecting unsheltered individuals to stable housing rather than displacing them through sweeps. This method employs evidence-based practices to connect people with housing solutions and prevent re-encampment, involving a wide range of stakeholders to address both the needs of the encampment residents and the community’s broader concerns.

This research letter discusses the experience of violence during homelessness, its impact on health, and recommendations for intervention. In the California Statewide Study of People Experiencing Homelessness, 38% of participants experienced violence during their current homelessness episode, and 74% of participants reported experiencing violence at some point in their lives. These results highlight the need to address violence against people experiencing homelessness through safer housing options, trauma-informed care, and long-term violence prevention strategies.

People experiencing homelessness are at an increased danger of dying. A recent study by the National Bureau of Economic Research showed a 40-year-old person experiencing homelessness has a similar risk of death as a 60-year-old person with housing. Previous studies have also found that people who experience homelessness have a greater mortality risk. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "We’re letting people die because we’re not fixing the underlying crisis."

A groundbreaking UCSF BHHI study challenges common perceptions about drug use among people experiencing homelessness. Researchers found that less than half of this population regularly used drugs, with methamphetamine being the most common substance, not opioids. Many respondents wanted treatment but struggled to access it, highlighting barriers to care. The study emphasizes that homelessness and substance use are interconnected and advocates for reducing barriers to treatment and prioritizing housing solutions. "We need to reduce barriers to substance use treatment, and that includes prioritizing people’s ability to return to housing,” said BHHI faculty member Ryan Assaf, PhD, MPH, the study’s lead author.

A comprehensive new study finds the vast majority of the California's unhoused residents lived in the state before losing their housing. The goal of the report was to take a systematic approach to understanding the causes of homelessness and potential solutions instead of relying on the emotional responses the crisis can trigger, said study author Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative. “What we were trying to do is take the rhetoric down a bit, and using really scientific best practices, to get a handle on not only who was experiencing homelessness but what was happening in their lives before they became homeless,” Dr. Kushel said.

Most people experiencing homelessness in California are not regular drug users — and for some, substance use begins or worsens after losing housing. Some use drugs to stay awake and safe, coping with the trauma and danger of life without shelter. At the same time, many who want treatment can’t get it. This paper uses data from the California Statewide Study of People Experiencing Homelessness to show a comprehensive, representative look at substance use, overdose risk, and unmet treatment needs among people experiencing homelessness in California.

A landmark study by UCSF Benioff Homelessness and Housing Initiative (BHHI) paints a different picture on people experiencing homelessness in California. Researchers at BHHI sought to capture the experiences of all people aged 18 years and older who experience some form of homelessness in California. "It took a lot of time and was a lot of work, but we wanted to be able to show policymakers what this issue looks like instead of just giving them more numbers to look at," said Margot Kushel, MD, the study’s principal investigator and director of UCSF’s Benioff Homelessness and Housing Initiative.

Hosted by the California Partnership to End Domestic Violence (the Partnership), lead researcher Anita Hargrave, MD, UCSF BHHI Policy Director Tiana Moore, PhD, and CPEDV staff dove deeper into policy recommendations and solutions that arose from the California Statewide Study of People Experiencing Homelessness (CASPEH) findings on the intersection of intimate partner violence and homelessness. The webinar featured an in-depth discussion of local and state opportunities, as well as funding and programmatic policy recommendations for advocates, policymakers, and other decision-makers.

A special report on the relationship between intimate partner violence and homelessness in California by the UCSF Benioff Homelessness and Housing Initiative, found that 1 in 5 women who become homeless in California flee their homes to escape violence. Participants described the need to plan their exit in advance and to accumulate resource; however, of those who experienced intimate partner violence in the 6 months prior to homelessness, only 12% sought help from a domestic violence organization. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "Some people honestly had no idea what is a domestic violence shelter. Other people told us when they had to run, they had to run. They didn’t have time to figure out where to find a shelter."

Domestic violence is a major but often overlooked driver of homelessness in Los Angeles, with 44% of unhoused women citing it as the primary cause, according to a 2023 Urban Institute survey. Yet, LA’s survivor support system is severely underfunded—only 10% of those seeking shelter secure a bed. A UCSF BHHI study found that 60% of survivors who fled abuse end up sleeping in cars, tents, or the streets, where they remain vulnerable to further violence. Experts and advocates warn that without integrating domestic violence services into homeless support systems—and vice versa—thousands will continue to face impossible choices and unsafe conditions.

With modern home prices out of reach for many California residents on fixed incomes, older adults have become the fastest-growing segment of the unhoused population across the state, according to new research from UCSF. California makes up 30% of the nation’s unhoused population and is home to half of all the country’s unsheltered population, according to the landmark study, which looks at how people in the Golden State become unhoused, experience homelessness, and exit homelessness. Nearly half of all unhoused adults in the study were age 50 or older, and Black and Native American residents were “dramatically overrepresented,” the study shows. “The results of the study confirm that far too many Californians experience homelessness because they cannot afford housing,” said Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative and principal investigator of the landmark study.

A new UCSF BHHI study challenges misconceptions about drug use among people experiencing homelessness in California. While only 37% of homeless individuals regularly use illicit drugs, lifetime use is high, and 27% began using after losing housing. The study highlights the difficulty of accessing treatment, with only 7% receiving care and 1 in 5 actively seeking help but unable to get it. Margot Kushel, MD, emphasized the complex relationship between drug use and homelessness, stating, “People are telling us that it helps them survive,” she said. “It keeps them awake and alert. They are using it either because they are traumatized, they have been assaulted, they are afraid or depressed, using it as coping to make it all go away.”

The California Statewide Study on People Experiencing Homelessness is the largest representative study on homelessness since the 1990s. The research highlighted crucial aspects of homelessness and debunked several myths. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative and principal investigator of the landmark study emphasized the urgent need for a national effort to combat homelessness, building upon the insights gained from the California study.

Everyday 171,000 people experience homelessness in California; in rural areas, in urban areas, throughout California. Margot Kushel, MD, director of UCSF’s Benioff Homelessness and Housing Initiative and lead investigator spoke with the host of the California Sun podcast, Jeff Schechtman, about the recent study released by the UCSF Benioff Homelessness and Housing Initiative. When speaking about root causes, Dr. Kushel said, "The root cause comes back to just housing. It is right there in the name, to be homeless is to not have a home". 

Among people experiencing homelessness in California, the group rising the fastest by proportion is older adults. A recent special report released by the UCSF Benioff Homelessness and Housing Initiative on older adult homelessness highlights their experiences during homelessness, and what impacted their return to permanent housing. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "The dramatic rise in homelessness among older adults has severe consequences for the health and safety of those who experience it and for our society at large. Now is the time for investments in real solutions to prevent and end homelessness among this vulnerable population."

Among people experiencing homelessness in California, nearly half of the population is now over the age of 50. By 50, a homeless person’s health more closely resembles that of someone in their 70s, with a higher chance of chronic disease, mobility issues, and cognitive decline, according to a recent special report released by the UCSF Benioff Homelessness and Housing Initiative on older adult homelessness. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "We could meaningfully reduce the number of people experiencing homelessness if we focused on this group."

A landmark study by UCSF Benioff Homelessness and Housing Initiative (BHHI) paints a different picture on people experiencing homelessness in California. The report released in June 2023, examines the demographics of people experiencing homelessness in California, how people enter and experience homelessness, factors that block or enable a person’s return to housing, and policy recommendations.

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.”

People experiencing homelessness in California are already a vulnerable group, often struggling with poor health, trauma, and deep poverty before losing their housing. Margot Kushel, MD, the study's principal investigator and director of UCSF’s Benioff Homelessness and Housing Initiative spoke with KTVU news about the key findings and recommendations. Dr. Kushel said, "These are not folks coming into California once they are homeless. They are our neighbors, our friends, our community members."

Dr. Kushel said, "the main drivers of homelessness are deep poverty."
