The San Mateo County Human Services Agency (HSA), in close collaboration with community partners, conducts the bi-annual One Day Homeless Count and Survey. The purpose of the One Day Homeless Count and Survey is to gather information to help the community understand homelessness in San Mateo County. This is one data set, among others, that provides information for effective planning of services to assist people experiencing homelessness and people at risk of homelessness.

HSA conducted the Count on February 24 and conducted the Survey between February 24 and March 3, 2022.

The 2022 One Day Homeless Count reports are posted below.
