Homeless Population

San Francisco's Biennial Point-in-Time (PIT) Count

Measure Description

The number of individuals in San Francisco experiencing homelessness during the biennial Point-in-Time (PIT) count. The count includes two categorizations of homelessness: 

  • Unsheltered: A nighttime count of unsheltered homeless individuals and families. This includes people sleeping outdoors on the street; at bus and train stations; in parks, tents, and makeshift shelters; and in vehicles and abandoned properties. 
  • Sheltered: A count of homeless individuals and families staying at publicly and privately operated shelters the night of the count. This includes those in emergency shelters, transitional housing, safe parking sites, and domestic violence shelters.

The measure is a Citywide trend measure with no performance target.

Why this Measure is Important

Reporting on this measure provides a snapshot of homelessness in San Francisco. This measure helps inform legislation and programs by showing trends over time including how many people need homeless services and what types of services are needed. 

The Department of Housing and Urban Development (HUD) requires all communities who receive federal funding for homelessness services to conduct a PIT count.

How Performance is Measured

Although generally a higher proportion (52% in FY24) of those experiencing homelessness are unsheltered, the number of homeless people in shelters has increased each PIT Count. Pre-pandemic sheltered counts increased by 64.2% since 2015, from 2,417 to 3,969.
