San Mateo County strives to end homelessness in our community, reaching and maintaining Functional Zero, where every unsheltered homeless person who chooses assistance will be provided interim or permanent housing.  The data presented here is our story of homelessness told through various data sources.

Key Indicators

These are some highlights of the key data that provides a system view of the number of people experiencing homelessness in our community, and those who are residing in interim housing or receiving services on the streets. The ultimate goal to end homelessness is permanent housing, which involves a collective County effort across departments to increase the supply and availability of affordable housing.
