People Receiving Homeless Response Services by Age, Race, Gender, Veteran Status, and Disability Status

Yearly statewide and by-Continuum of Care total counts of individuals receiving homeless response services by age group, race, gender, veteran status, and disability status. 

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 2026 HUD Data Standard changes. Gender data is sourced from prior uploads and matched to the most recent HMIS uploads from each CoC. Sex data, introduced in the federally mandated HUD HMIS FY2026 Data Standards updates, will begin to be reported on in Calendar Year 2026. All Gender and Sex data is incomplete for Calendar Year 2025, and therefore not presented here or on the HDIS public dashboard.

Information updated as of 05/19/2026.
Clifton Court Forebay Predation Study - Fish Sampling

This dataset is part of the Clifton Court Forebay Predation Study, a multi-year effort led by the California Department of Water Resources to understand the behavior and movement of predatory fishes and fish-eating birds within Clifton Court Forebay. The broader study supports requirements outlined in the 2009 National Marine Fisheries Service Biological Opinion and aims to evaluate conditions that contribute to fish predation risk.

This dataset contains data on predatory fish which were collected during the 2013-2018 CCFPS studies. Fish were captured using hook and line or gillnet sampling. Fish were assessed for previous tags, weighed and fork length measured and implanted with PIT tags and floy tags, some fish were implanted with Acoustic Tags.
California Seed Bank Assessment of Needs App

This app is a tool designed for individuals interested in California's reforestation efforts. Users can look up local reforestation information or select broader geographic regions. Mapped seed zone and elevation band areas are color-coded by collection priority. Priority ranges from the highest colored in red (greater than 100 cone bushels needed) to the lowest in yellow (10 bushels or less). Interactive pop-ups display zone-specific cone bushel need and surplus and natural disturbance data to non-federal conifer forests. Disturbance data includes total and high-severity acreage burned by large wildfires, acreage affected by insects and disease, and tree mortality due to such diseases. Supplementary layers include CAL FIRE timber harvesting data, demonstration state forests, and administrative boundaries, such as parcel information and land ownership.
Active Transportation Count Dataset

The Pedestrian and Bicycle Count Dataset documents non motorized traffic on state highways, originating from Caltrans district pilots initiated in 2023 to monitor active transportation. Data is vendor-collected using technologies like video analytics, then shared with HQ via APIs or files for statewide standardization in CSV format. Core variables include Loc_id (site identifier), Date/Hour (timestamp), Direction, Count (integer volumes), and geospatial (latitude/longitude). Limitations include potential undercounts in adverse weather and incomplete coverage. This supports equity-focused planning under Complete Streets policies, with updates as pilots expand.
Live Births with Low and Very Low Birthweight (ARCHIVED)

This dataset contains tables with the percent of live births with low birthweight and very low birthweight: 1) by maternal county of residence 2) by race/ethnicity group of mother. Low birthweight are live births weighing less than 2,500 grams (approximately 5 pounds, 8 ounces). Very low birthweight are live births weighing less than 1,500 grams (approximately 3 pounds, 5 ounces). Low and very low birthweight can be associated with very serious health problems for the infant and can lead to certain serious health conditions later in life. Data includes births with birthweight of 227 to 8,165 grams and excludes non-California residents.
Sustainable Groundwater Management Act (SGMA) Water Year Type Dataset

The following dataset has been developed to assist the Groundwater Sustainability Agencies (GSAs) in their water budget development per the Groundwater Sustainability Plan Regulations §354.18. GSAs may choose to use this dataset but are not required. GSAs have the option to develop their own water year types based on best available data. For information on how the SGMA Water Year Type Dataset was developed, please see the SGMA Water Year Type Dataset Development Report.

2016 Clifton Court Forebay Predator Reduction Electrofishing Study

The Clifton Court Forebay (CCF) Predator Reduction Electrofishing Study (Study) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015, requiring that the California Department of Water Resources (DWR) immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project (NMFS 2009 BiOp). The study length totaled three years, beginning with a pilot year effort in 2016. The study electroshocked and removed predators from CCF and transported them to Bethany Reservoir with the goal of decreasing pre-screen loss of protected fish species with an emphasis on Chinook Salmon and steelhead .
Primary Written Language of Individuals Selecting Covered California Qualified Health Plan (QHP)

This dataset includes the primary written language of eligible individuals who selected and enrolled in a Covered California Qualified Health Plan (QHP) and identified their primary written language as English, Spanish, Traditional Chinese character, Korean, Vietnamese, Mandarin, Cantonese, Russian, Tagalog, Farsi, Arabic, Cambodian, Armenian, or Hmong, by reporting period. Covered California reported data is from the California Healthcare Eligibility, Enrollment and Retention System (CalHEERS) and includes those who selected and enrolled in a QHP, and paid their first premium. This dataset is part of public reporting requirements set forth by the California Welfare and Institutions Code 14102.5.
Surface Water - Habitat Results

This data provides results from field analyses, from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN). The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result.

Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data.

Users who want to manually download more specific subsets of the data can also use the [CEDEN Query Tool](https://ceden.waterboards.ca.gov/CQT/Home/AqtTool), which provides access to the same data presented here, but allows for interactive data filtering.
Ethnicity of Individuals Selecting Covered California Qualified Health Plan (QHP)

This dataset includes the ethnicity of eligible individuals who selected and enrolled in a Covered California Qualified Health Plan (QHP) and identified their ethnicity as Hispanic with the ethnic origin as Mexican/Mexican American/Chicano, Other, Mixed, Puerto Rican, or Cuban, Hispanic with ethnic origin not reported, not Hispanic, or ethnicity not reported, by reporting period. Covered California reported data is from the California Healthcare Eligibility, Enrollment and Retention System (CalHEERS) and includes those who selected and enrolled in a QHP, and paid their first premium. This dataset is part of public reporting requirements set forth by the California Welfare and Institutions Code 14102.5.
COVID-19 Vaccine Progress Dashboard Data by ZIP Code

__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses.

Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 12+ and age 5+ denominators have been uploaded as archived tables. 

Starting June 30, 2021, the dataset has been reconfigured so that all updates are appended to one dataset to make it easier for API and other interfaces. In addition, historical data has been extended back to January 5, 2021.

This dataset shows full, partial, and at least 1 dose coverage rates by zip code tabulation area (ZCTA) for the state of California. Data sources include the California Immunization Registry and the American Community Survey’s 2015-2019 5-Year data.

This is the data table for the [LHJ Vaccine Equity Performance dashboard](https://public.tableau.com/profile/ca.open.data#!/vizhome/LHJVaccineEquityPerformance/MapView?publish=yes). However, this data table also includes ZTCAs that do not have a VEM score.

This dataset also includes Vaccine Equity Metric score quartiles (when applicable), which combine the Public Health Alliance of Southern California’s Healthy Places Index (HPI) measure with CDPH-derived scores to estimate factors that impact health, like income, education, and access to health care. ZTCAs range from less healthy community conditions in Quartile 1 to more healthy community conditions in Quartile 4.

The Vaccine Equity Metric is for weekly vaccination allocation and reporting purposes only. CDPH-derived quartiles should not be considered as indicative of the HPI score for these zip codes. CDPH-derived quartiles were assigned to zip codes excluded from the HPI score produced by the Public Health Alliance of Southern California due to concerns with statistical reliability and validity in populations smaller than 1,500 or where more than 50% of the population resides in a group setting.

These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons.

For some ZTCAs, vaccination coverage may exceed 100%. This may be a result of many people from outside the county coming to that ZTCA to get their vaccine and providers reporting the county of administration as the county of residence, and/or the DOF estimates of the population in that ZTCA are too low. Please note that population numbers provided by DOF are projections and so may not be accurate, especially given unprecedented shifts in population as a result of the pandemic.
Statewide Live Birth Profiles

This dataset contains counts of live births for California as a whole based on information entered on birth certificates. Final counts are derived from static data and include out of state births to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all births that occurred during the time period.

The final data tables include both births that occurred in California regardless of the place of residence (by occurrence) and births to California residents (by residence), whereas the provisional data table only includes births that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by parent giving birth's age, parent giving birth's race-ethnicity, and birth place type. See temporal coverage for more information on which strata are available for which years.
Automated Eligibility Verification System (AEVS): Carrier Codes for Other Health Coverage

This dataset provides basic information about third parties who may be liable for medical expenses that would otherwise be paid by Medi-Cal. This information is based on a point in time and is expected to be updated monthly. The data is retrieved from the Carrier Code Master File (CCMF), which is used to bill liable third parties to ensure Medi-Cal remains the payer of last resort.

__Note: Please see resource description for information regarding file specific updates.__
California Conservation Easement Database

The California Conservation Easement Database (CCED) contains lands protected under conservation easements. It is a parallel data set to the California Protected Areas Database (CPAD), which covers protected areas owned in fee. The first version of the CCED database was released in April 2014, the latest update is from June 2026.

CCED is maintained and published by GreenInfo Network (www.greeninfo.org). GreenInfo Network publishes CCED twice annually.
Insurance Affordability Programs Applications Received Through County Offices, by Submission Channel

The total number of Insurance Affordability Programs (IAPs) applications received through County Human Services Agency offices by submission channel (whether submitted online, in-person, phone, e-mail, mail/fax, other, or unknown) during a reporting period. The “outreach” submission channel may be included in the “other” submission channel commencing with 2016 Quarter 3.  IAPs include Medi-Cal or subsidized Qualified Health Plans (QHPs) offered through Covered California. This dataset is part of the public reporting requirements set forth in the California Welfare and Institutions Code 14102.5(1)(A).
Total Construction Cost of Healthcare Projects

Total dollar value and number of projects either in review, pending construction, in construction, or in closure aggregated into California counties, once every two weeks since September 2013.  A construction project moves through the Department of Health Care Access and Information (HCAI) in four stages - In Review; Pending Construction Start; Under Construction; and In Closure. A project can only be in one of these four stages at any time. Additional data when available will be added to this dataset approximately once every two weeks.
Dental Utilization Measures and Sealant Data by Age Groups Calendar Year 2013 to 2024

This dataset shows the use of Medi-Cal dental benefits by Medi-Cal members, displayed by age group and calendar year (for 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024). This information is displayed in the following categories: Annual Dental Visit, Exams/Oral Health Evaluations, Use of Diagnostic Services, Use of Dental Treatment Services, Use of Preventive Services, Use of Restorative Services, Treatment/Prevention for Caries, and Use of Sealants. The Medi-Cal members were continuously enrolled in either Dental Managed Care or the dental Fee-for-Service delivery system for the entire measurement period.
Housing Element Compliance Report

California requires that all local governments (cities and counties) adequately plan to meet the housing needs of everyone in the community. California’s local governments meet this requirement by adopting housing plans as part of their “general plan”. General plans serve as the local government’s "blueprint" for how the city and/or county will grow and develop and include eight elements: land use, transportation, conservation, noise, open space, safety, environmental justice, and housing.

The Housing Element Compliance Report provides current Housing Element Compliance Status. Additional information about Housing Elements can be found on HCD’s website here: https://www.hcd.ca.gov/planning-and-community-development/housing-elements.
Water Shortage Vulnerability Technical Methods

These documents present the updates to the Water Shortage Vulnerability scoring for both (and separately) rural communities as domestic wells and state small water systems and separately for small water systems, including the indicators, datasets, and methods used, and a statistical summary of results. This is an update to the scoring and tool that the California Department of Water Resources (DWR) submitted to the legislature in April 2021, developed in collaboration with the County Drought Advisory Group (CDAG) (DWR 2021).

Measles Activity in California

Data were extracted on measles cases with an estimated rash onset or episode date from January 1, 2026 through the last week indicated, from California Confidential Morbidity Reports and/or Laboratory Reports that were submitted to CDPH and which met the surveillance case definition for that disease.  If the rash onset was unknown, the earliest available date from the following was used as episode date: symptom onset, diagnosis, laboratory specimen collection, reported to public health. Because of inherent delays in case reporting and depending on the length of follow-up of clinical, laboratory and epidemiologic investigation, cases with eligible onset dates may be added or rescinded after the date of this report.
