Snapshot: Point-in-Time Count
Cities and counties across the United States conduct PIT counts to establish a baseline number of people experiencing homelessness in their community. In addition to informing local targets and policy planning, the Department of Housing and Urban Development funds rental subsidies and other supportive services on the basis of the PIT counts. Every two years in San Francisco, hundreds of volunteers participate in the count of unsheltered people from 8pm-12am on an evening in January. Volunteers receive an hour of training, then travel throughout the city. The sheltered count is conducted by service providers within shelters, navigation centers, hospitals, and jails.
The unsheltered count in San Francisco is “visual-only,” meaning that volunteers do not engage with people experiencing homelessness while counting them. During subsequent weeks, HSH follows up with a subset of around 1,000 people to survey them in detail about their experience with homelessness. For example, we learn about the circumstances that led to homelessness and the traits of people experiencing homelessness, such as age, health, and race. San Francisco’s visual-only count is intended to provide a consistent comparison from one PIT count to the next, but we know that we are likely undercounting, missing individuals and families who are "doubled up" (i.e. staying with others), and those who are housing insecure and moving in and out of homelessness over the course of a year.
San Francisco is unlikely to shift away from the visual-only PIT methodology in the near future, given the importance of maintaining a consistent point of comparison. However, with the ONE System now online for families and close to completion for adults, the City can rely on even more current and robust data when serving our neighbors experiencing homelessness. The ONE System offers a unified, up-to-date view of people experiencing homelessness, what services they’ve received, and whether or not they now have housing. While biennial PIT counts will remain important to track progress and to maintain federal support for local rental subsidies, City officials hope the ONE System will help accelerate the process of reducing homelessness in San Francisco.
