Yearly statewide and by-Continuum of Care total counts of individuals receiving homeless response services by age group, race, and gender. This data comes from the Homelessness Data Integration System (HDIS), a statewide data warehouse which compiles and processes data from all 44 California Continuums of Care (CoC)—regional homelessness service coordination and planning bodies. Each CoC collects data about the people it serves through its programs, such as homelessness prevention services, street outreach services, permanent housing interventions and a range of other strategies aligned with California’s Housing First objectives. The dataset uploaded reflects the 2024 HUD Data Standard Changes. Previously, Race and Ethnicity are separate files but are now combined. Information updated as of 7/15/2024.

The California System Performance Measures (CA SPMs) are a series of metrics developed by the California Interagency Council on Homelessness (Cal ICH), pursuant to Health and Safety Code §50220.7, that help the state and local jurisdictions assess their progress toward preventing, reducing, and ending homelessness. All measures except for Measure 1b are generated using data from the state’s Homelessness Data Integration System. Measure 1b and Point in Time (PIT) Count data are sourced from each Continuum of Care’s PIT Count. Measure 1b and PIT Count data are not shown for 2021 because of irregularities in that year’s counts. For more information about the measures and how they are calculated, please see the California System Performance Measures Guide and Glossary: https://www.bcsh.ca.gov/calich/documents/california_system_performance_measures_guide.pdf

For more information about Measure 1b and PIT Count data, please see the Department of Housing and Urban Development’s website: https://www.hudexchange.info/programs/hdx/pit-hic.

Components of the Homeless Count

Street Count (all census tracts): Captures a point in time estimate of the unsheltered population.

Shelter Count (from Homeless Management Integration System): Captures the homeless population in emergency shelters, transitional housing, safe havens and vouchered motels/hotels.

Youth Count (sample census tracts): Collaborative process with youth stakeholders to better understand and identify homeless youth.

Demographic Survey (sample census tracts): Captures the demographic characteristics of the unsheltered homeless population.

Notes

Street Count Data include persons found outside, including persons found living in cars, vans, campers/RVs, tents, and makeshift shelters. The conversion factors used to estimate the number of persons found living outside are the following: For families—Makeshift Shelter = 3.69, Car = 2.96, Van = 3.46, Camper/RV = 3.52, Tent = 3.78; For Individuals—Makeshift Shelter = 1.92, Car = 1.52, Van = 1.77, Camper/RV = 2.05, Tent = 1.69.

The following conversion factors were used to estimate the number of persons living in cars, vans, campers/RVs, tents and makeshift shelters if enumerators encountered homeless persons living in these environments. Individuals: Cars = 1.54, Vans = 1.62, RV's = 1.76, Tents = 1.52 and Makeshift Shelters = 1.67. Family Members: Cars = 2.96, Vans = 2.43, RV's = 3.45, Tents = 2.75 and Makeshift Shelters = 2.42. Demographic survey interviews conducted with 4,934 homeless persons from December 2017 to March 2018 determined these conversion factors for the average number of homeless persons in cars, vans, campers/RVs, tents and makeshift shelters.

The lives of persons living with mental illness are affected by psychological, biological, social, economic, and environmental factors over the life course. It is therefore unlikely that simple preventive strategies, clinical treatments, therapeutic interventions, or policy options will succeed as singular solutions for the challenges of mental illness. Persons living with mental illness receive services and supports in multiple settings across the health care continuum that are often fragmented, uncoordinated, and inadequately responsive. Appropriate assessment is an important tool that health systems must deploy to respond to the strengths, preferences, and needs of persons with mental illness. However, standard approaches are often focused on measurement of psychiatric symptoms without taking a broader perspective to address issues like growth, development, and aging; physical health and disability; social relationships; economic resources; housing; substance use; involvement with criminal justice; stigma; and recovery. Using conglomerations of instruments to cover more domains is impractical, inconsistent, and incomplete while posing considerable assessment burden. interRAI mental health instruments were developed by a network of over 100 researchers, clinicians, and policy experts from over 35 nations. This includes assessment systems for adults in inpatient psychiatry, community mental health, emergency departments, mobile crisis teams, and long-term care settings, as well as a screening system for police officers. A similar set of instruments is available for child/youth mental health. The instruments form an integrated mental health information system because they share a common assessment language, conceptual basis, clinical emphasis, data collection approach, data elements, and care planning protocols. The key applications of these instruments include care planning, outcome measurement, quality improvement, and resource allocation. The composition of these instruments and psychometric properties are reviewed, and examples related to homeless are used to illustrate the various applications of these assessment systems.
