Using data submitted from California’s Continuums of Care (CoCs), HDIS can calculate the number of people experiencing homelessness who have accessed services from multiple local homelessness response systems.
Attempting to determine whether people experiencing homelessness travel in search of needed services is challenging. However, newly available data from HDIS shows that over a three-year timespan, within California, very few people experienced homelessness in more than one CoC. Of the people who did access services in multiple jurisdictions, most did so in adjacent or neighboring CoCs, suggesting homelessness within California is not a problem of migration. Among the records analyzed in HDIS:
Data Sources and Notes
Homeless Data Integration System (HDIS). HDIS includes Federally required data collected from all service providers that participate in CoCs’ local Homeless Management Information Systems (HMIS). However, not all providers participate in HMIS. Independent providers that do not receive Federal funding or certain State funding can opt out of participation in local HMIS. Dedicated domestic violence victim service providers are barred by Federal law from entering their clients’ data into HMIS and maintain separate data systems. Some permanent housing programs for veterans are also captured in a separate data system from HMIS. Additionally, not all people experiencing homelessness are captured in HDIS. People experiencing homelessness who do not access services are not captured in local HMIS or HDIS. Certain unaccompanied youth providers may not be allowed to share complete client data with HDIS.
In this release, 42 of California’s 44 CoCs submitted data to HDIS. San Mateo County CoC and Yuba/Sutter Counties CoC did not submit data in time to be included.
