The dataset contains hospitalization counts and rates, statewide and by county, for 10 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; community-acquired pneumonia; urinary tract infection; uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall, acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI (formerly OSHPD) only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

This dataset represents measurements of vertical ground surface displacement in more than 200 of the high-use and populated groundwater basins across the State of California between January of 2015 and April of 2022. Vertical displacement estimates are derived from Interferometric Synthetic Aperture Radar (InSAR) data that are collected by the European Space Agency (ESA) Sentinel-1A satellite and processed by TRE ALTAMIRA Inc. (TRE), under contract with the California Department of Water Resources (DWR) as part of DWR’s SGMA technical assistance to provide important SGMA-relevant data to GSAs for GSP development and implementation. Sentinel-1A InSAR data coverage began in late 2014 for parts of California, and coverage for the entire study area began in June 13, 2015. Included in this dataset are point data that represent average vertical displacement values for 100 meter by 100 meter areas, as well as GIS rasters that were interpolated from the point data; rasters for total vertical displacement relative to June 13, 2015, and rasters for annual vertical displacement rates with earlier coverage for some areas, both in monthly time steps. Towill Inc. (Towill), also under contract with DWR as part of DWR’s SGMA technical assistance, conducted an independent study comparing the InSAR-based vertical displacement point time series data to data from Continuous Global Positioning System (CGPS) stations. The goal of this study was to ground-truth the InSAR results to best available independent data. Data update frequency: Quarterly Report update frequency: Annual

2019 (v2020) Rates of Preventable Hospitalizations for Selected Medical Conditions by County
This data table reports the monthly number of deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

The Groundwater Sustainability Plan (GSP) Monitoring dataset contains the monitoring sites and associated groundwater level, subsidence or streamflow measurements collected by Groundwater Sustainability Agencies (GSA) during implementation of their GSP. All data is submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). The GSP Regulations established the monitoring network criteria (23 CCR § 354.34) and the data and reporting standard for monitoring sites and measurements (23 CCR § 352.4). The data fields associated with these datasets were created by DWR to ensure that GSAs electronically submit monitoring site and measurement data which meets the GSP Regulation’s data and reporting standards. For additional information regarding GSAs, GSPs, and SGMA related monitoring, please view DWR’s SGMA Portal Resources at https://sgma.water.ca.gov/portal/.

Wastewater discharges are regulated by the Water Board. Those regulated are generally required to submit Self-Monitoring Reports to the State or Regional Water Board. Some dischargers submit their reports through the electronic Self-Monitoring Report (eSMR) module of the California Integrated Water Quality System (CIWQS). Generally these are for discharges into surface waters regulated by an individual National Pollutant Discharge Elimination System (NPDES) permit, though other dischargers may be included in this dataset as well. This dataset are the monitoring results that have been submitted as data points after the submitters have been approved for electronic submittals (i.e. after the "all electronic date"). Note that this dataset does not include records where the sampling date falls outside of the years shown below. The excluded records include: records where the sampling date is missing, records where the sampling date is invalid (e.g., records with sampling dates in the future or unreasonably far in the past), and records for samples taken prior to year 2006. The excluded records represent approximately 0.1% of all records in the complete eSMR dataset.

Water Chemistry data for year 2000 from the California Environmental Data Exchange Network (CEDEN).
__Data is from the California Department of Public Health (CDPH) Respiratory Virus Weekly Report.__ The report is updated each Friday. __Laboratory surveillance data__: California laboratories report SARS-CoV-2 test results to CDPH through electronic laboratory reporting. Los Angeles County SARS-CoV-2 lab data has a 7-day reporting lag. Test positivity is calculated using SARS-CoV-2 lab tests that has a specimen collection date reported during a given week. Laboratory surveillance for influenza, respiratory syncytial virus (RSV), and other respiratory viruses (parainfluenza types 1-4, human metapneumovirus, non-SARS-CoV-2 coronaviruses, adenovirus, enterovirus/rhinovirus) involves the use of data from clinical sentinel laboratories (hospital, academic or private) located throughout California. Specimens for testing are collected from patients in healthcare settings and do not reflect all testing for influenza, respiratory syncytial virus, and other respiratory viruses in California. These laboratories report the number of laboratory-confirmed influenza, respiratory syncytial virus, and other respiratory virus detections and isolations, and the total number of specimens tested by virus type on a weekly basis. Test positivity for a given week is calculated by dividing the number of positive COVID-19, influenza, RSV, or other respiratory virus results by the total number of specimens tested for that virus. Weekly laboratory surveillance data are defined as Sunday through Saturday. __Hospitalization data__: Data on COVID-19 and influenza hospital admissions are from Centers for Disease Control and Prevention’s (CDC) National Healthcare Safety Network (NHSN) Hospitalization dataset. The requirement to report COVID-19 and influenza-associated hospitalizations was effective November 1, 2024. CDPH pulls NHSN data from the CDC on the Wednesday prior to the publication of the report. Results may differ depending on which day data are pulled. Admission rates are calculated using population estimates from the P-3: Complete State and County Projections Dataset provided by the State of California Department of Finance (https://dof.ca.gov/forecasting/demographics/projections/). Reported weekly admission rates for the entire season use the population estimates for the year the season started. For more information on NHSN data including the protocol and data collection information, see the CDC NHSN webpage (https://www.cdc.gov/nhsn/index.html). CDPH collaborates with Northern California Kaiser Permanente (NCKP) to monitor trends in RSV admissions. The percentage of RSV admissions is calculated by dividing the number of RSV-related admissions by the total number of admissions during the same period. Admissions for pregnancy, labor and delivery, birth, and outpatient procedures are not included in total number of admissions. These admissions serve as a proxy for RSV activity and do not necessarily represent laboratory confirmed hospitalizations for RSV infections; NCKP members are not representative of all Californians. Weekly hospitalization data are defined as Sunday through Saturday. __Death certificate data__: CDPH receives weekly year-to-date dynamic data on deaths occurring in California from the CDPH Center for Health Statistics and Informatics. These data are limited to deaths occurring among California residents and are analyzed to identify influenza, respiratory syncytial virus, and COVID-19-coded deaths. These deaths are not necessarily laboratory-confirmed and are an underestimate of all influenza, respiratory syncytial virus, and COVID-19-associated deaths in California. Weekly death data are defined as Sunday through Saturday. __Wastewater data__: This dataset represents statewide weekly SARS-CoV-2 wastewater summary values. SARS-CoV-2 wastewater concentrations from all sites in California are combined into a single, statewide, unit-less summary value for each week, using a method for data transformation and aggregation developed by the CDC National Wastewater Surveillance System (NWSS). Please see the CDC NWSS data methods page for a description of how these summary values are calculated. Weekly wastewater data are defined as Sunday through Saturday.

This reference table, maintained by DHCS, displays aid code categories by aid code. Aid codes identify the criteria by which each person qualifies for Medi-Cal and the types of services he or she receives, and make clear whether the services are funded by the State or Federal government or both. An aid code is a combination of two numbers or a letter and a number and is attached to a Medi-Cal beneficiary’s identification numbers. Aid code category refers to a unique grouping of distinct aid codes into broad categories such as CHIP, Seniors and Persons with Disabilities, and Long-Term Care. For a description of each aid code, see the [Medi-Cal Aid Code Master Chart](https://files.medi-cal.ca.gov/pubsdoco/publications/masters-mtp/part1/aidcodes.pdf "Medi-Cal Aid Code Master Chart").

__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. On 6/16/2023 CDPH replaced the booster measures with a new “Up to Date” measure based on CDC’s new recommendations, replacing the primary series, boosted, and bivalent booster metrics The definition of “primary series complete” has not changed and is based on previous recommendations that CDC has since simplified. A person cannot complete their primary series with a single dose of an updated vaccine. Whereas the booster measures were calculated using the eligible population as the denominator, the new up to date measure uses the total estimated population. Please note that the rates for some groups may change since the up to date measure is calculated differently than the previous booster and bivalent measures. This data is from the same source as the Vaccine Progress Dashboard at https://covid19.ca.gov/vaccination-progress-data/ which summarizes vaccination data at the county level by county of residence. Where county of residence was not reported in a vaccination record, the county of provider that vaccinated the resident is included. This applies to less than 1% of vaccination records. The sum of county-level vaccinations does not equal statewide total vaccinations due to out-of-state residents vaccinated in California. 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. Totals for the Vaccine Progress Dashboard and this dataset may not match, as the Dashboard totals doses by Report Date and this dataset totals doses by Administration Date. Dose numbers may also change for a particular Administration Date as data is updated. Previous updates: * On March 3, 2023, with the release of HPI 3.0 in 2022, the previous equity scores have been updated to reflect more recent community survey information. This change represents an improvement to the way CDPH monitors health equity by using the latest and most accurate community data available. The HPI uses a collection of data sources and indicators to calculate a measure of community conditions ranging from the most to the least healthy based on economic, housing, and environmental measures. * 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 16+ and age 5+ denominators have been uploaded as archived tables. * Starting on May 29, 2021 the methodology for calculating on-hand inventory in the shipped/delivered/on-hand dataset has changed. Please see the accompanying data dictionary for details. In addition, this dataset is now down to the ZIP code level.

2018 (v2020) Rates of Preventable Hospitalizations for Selected Medical Conditions by County
The dataset contains hospitalization counts and rates, statewide and by county, for 6 conditions plus 3 composite measures. Hospitalizations for these conditions are potentially preventable through access to high-quality outpatient care. The conditions include: asthma (age 2-17), diabetes short-term complications (age 6-17), gastroenteritis (age 3 months-17 years), perforated appendix (age 1-17), urinary tract infections (age 3 months-17 years), and low birth weight (<2500 grams). The composite measures (age 6-17) include overall, acute conditions, and chronic conditions. The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016. The calculation of risk-adjusted rates is not available in the current version of PDI software.

Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a Structural Performance Category (SPC) which measures the probable seismic performance of building structural systems. Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by January 1, 2020, unless an approved extension has been granted, and all SPC 2 buildings to be removed from providing general acute care services by January 1, 2030. A hospital facility meets the January 1, 2030 requirements if all the general acute care buildings on campus are SPC and NPC compliant. 2030 compliant SPC ratings are either SPC 3, 4, 4D, or 5. 2030 compliant NPC ratings is NPC 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

This dataset supports the County SB 552 Progress Dashboard, which is published on DWR’s [County Drought Resilience Planning webpage](https://water.ca.gov/Programs/Water-Use-And-Efficiency/SB-552/County-Drought-Resilience-Planning-Assistance-Program). The dashboard summarizes county-reported information on SB 552 implementation, including the status of drought and water shortage task force formation, drought resilience plan development, and the types of planning assistance counties have received from DWR (financial or direct technical assistance). This page also links to a DWR-hosted document library containing completed County Drought Resilience Plans. Senate Bill (SB) 552 requires counties to improve drought and water shortage preparedness for state small water systems and domestic wells by establishing a standing Drought and Water Shortage Task Force and developing a County Drought Resilience Plan. These plans describe local drought and water shortage risks and potential interim and long-term solutions for state small water systems and domestic wells and may be stand-alone documents or incorporated into existing county plans. The dashboard data and linked plans do not indicate compliance with SB 552 and do not constitute review, approval, or endorsement of any planning documents or processes. DWR does not review or approve plans for SB 552 compliance, nor direct or monitor county task force processes. This dataset and dashboard were developed in response to frequent questions from counties about how SB 552 is being implemented statewide. If you are county staff and would like to update your county’s information, please complete [this form](https://cadwr.app.box.com/s/030ohmm8vr33yfioa5e0czo0hlmljpey) and email it to CountyDRP@water.ca.gov.

It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

The Dry Well Reporting System is for use by individuals not served by a public water system experiencing problems with their water supply and agencies receiving calls from those individuals. How is this information going to be used? This information is intended to inform state and local agencies on drought impacts on household water supplies. The Household Water Supply Shortage Reporting System was first created as part of our emergency response efforts to previous droughts, and we are continuing to gather information relating to shortages of household water from private well or surface water sources. Collection of data is not to be construed as application for local, state or federal assistance. Individuals interested in financial assistance will be directed towards appropriate resources. Data Collection Entails: - Contact information for Household experiencing water shortage - Water Shortage Problem Information and Location - Financial Resources Available - Well Log Data (optional) - Reporting Agency or Local Government Information
2019 (v2023) Rates of Preventable Hospitalizations (Age<18) for Selected Medical Conditions by County
In California, water systems serving one (1) to 15 households are regulated at the county level. Counties vary in their practices, but rarely do counties collect data regularly from these systems. Even where data is collected, it is entirely voluntary. A review of well permit information suggests there are over 1 million such water systems in California. In early 2014, a cross-agency Work Group created an easily accessible reporting system to get more systematic data on which parts of the state had households at risk of water supply shortages. The initial motivation for local water supply systems to report shortage information was to obtain statewide drought assistance. The reporting system receives ongoing reports of shortages from local, state, federal and non-governmental organizations, and tracks their status to resolution. While several counties have developed their own tracking mechanisms, this data is manually entered into the reporting system. The cross-agency team, led by DWR, seeks to verify and update the data submitted. However, due to the volunteer nature of the reporting and limitations on reporting agencies, collected data are undoubtedly under-representative of all shortages to have occurred. In addition, reports are received from multiple sources and there are occasionally errors and omissions that can create duplicate entries, non-household water supply reporting, and under-reporting. For example, missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county, rather only that none have been reported to the State.

Electronic Self-Monitoring Report (eSMR) data for samples collected in year 2015.
This data table reports the provisional monthly number of deaths that occurred in each California county regardless of the place of residence (by occurrence). __Provisional counts are based on the records available when the data was retrieved, given by Data\_Extract\_Date, and may not represent all deaths that occurred during the time period.__ Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes.

Hazardous waste identification (ID) numbers are issued by the U.S. Environmental Protection Agency (Federal EPA ID number) or by the Department of Toxic Substances Control (California State ID number). The ID number identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID number enables regulators to track the waste from its origin to final disposal, a process also referred to as “cradle to grave.” With a few exceptions, most hazardous waste generators must have an ID number before a registered hazardous waste transporter will accept their waste for shipment. All hazardous waste transporters and permitted treatment, storage, and disposal facilities (TSDFs) must have a hazardous waste ID number.

The Current Employment Statistics (CES) program is a Federal-State cooperative effort in which monthly surveys are conducted to provide estimates of employment, hours, and earnings based on payroll records of business establishments. The CES survey is based on approximately 119,000 businesses and government agencies representing approximately 629,000 individual worksites throughout the United States. CES data reflect the number of nonfarm, payroll jobs. It includes the total number of persons on establishment payrolls, employed full- or part-time, who received pay (whether they worked or not) for any part of the pay period that includes the 12th day of the month. Temporary and intermittent employees are included, as are any employees who are on paid sick leave or on paid holiday. Persons on the payroll of more than one establishment are counted in each establishment. CES data excludes proprietors, self-employed, unpaid family or volunteer workers, farm workers, and household workers. Government employment covers only civilian employees; it excludes uniformed members of the armed services. The Bureau of Labor Statistics (BLS) of the U.S. Department of Labor is responsible for the concepts, definitions, technical procedures, validation, and publication of the estimates that State workforce agencies prepare under agreement with BLS.

This dataset contains annual validated water loss audit reports submitted to the Department of Water Resources by California urban retail water suppliers, as required under Title 23, California Code of Regulations Section 638.5(c) (Regulation). California Water Code Section 10608.12(af) specifies that urban retail water suppliers are those water suppliers directly providing potable municipal water to more than 3,000 service connections or that supply more than 3,000 acre-feet per year at retail for municipal purposes. The Regulation mandates that urban retail water suppliers with multiple separate potable water systems submit a separate audit for each system, regardless of system size. The dataset includes individual water loss audits for all potable water systems owned by urban retail water suppliers, including reports from water suppliers newly classified as urban retail water suppliers. While all submissions are available at the WUEdata.ca.gov portal, this dataset provides a cleaned version with only the latest submissions (older submissions that were corrected are not included). Water system boundaries for the water system water loss data in this dataset may be available in the Water Board's DDW California Drinking Water System Area Boundaries (SABL) tool. The link to this tool can be found in Additional Resources as part of this dataset. Water loss audits evaluate real water losses (leaks) and apparent water losses (e.g. data errors, water theft) occurring in a potable water distribution system. Estimating the scale and cost of these losses allows utilities to identify opportunities for saving water and recovering revenue. California water loss audit submissions were reviewed by validators and submitted to DWR starting in 2016. The reviews followed the validation methodology detailed in Water Research Foundation Project 4639: Level 1 Water Audit Validation. Level 1 water audit validation aims to: * Identify and, where possible, correct inaccuracies in water audit data and application of methodology. * Evaluate and communicate the uncertainty inherent in water audit data. The data is provided "as is" (as submitted by the water systems). More information on this dataset can be found in the file "Data Source and Notes" available at the on the home page of this dataset.

This data table reports the statewide monthly number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

Medi-Cal law, _Welfare and Institutions Code_ (W&I Code), sections 14043.6 and 14123, mandate that the Department of Health Care Services (DHCS) suspend a Medi-Cal provider of health care services (provider) from participation in the Medi-Cal program when the individual or entity has: * Been convicted of a felony; * Been convicted of a misdemeanor involving fraud, abuse of the Medi-Cal program or any patient, or otherwise substantially related to the qualifications, functions, or duties of a provider of service; * Been suspended from the federal Medicare or Medicaid programs for any reason; * Lost or surrendered a license, certificate, or approval to provide health care; or * Breached a contractual agreement with the Department that explicitly specifies inclusion on this list as a consequence of the breach. __Suspension of Entities Submitting Claims for Suspended Providers__ Suspension is automatic when any of the above events occurs, and suspended Medi-Cal providers will not be entitled to a hearing under the _California Administrative Procedures Act_. Services rendered, prescribed or ordered by a suspended Medi-Cal provider shall not be covered by the Medi-Cal program while the suspension is in effect. _California Code of Regulations_, title 22, section 51303, subdivision (k), provides that at least fifteen (15) days written notice be given to all affected providers. This list constitutes such written notice. Although the period of suspension may have expired, reinstatement rights are not automatic. The provider must petition for reinstatement and re-enroll with DHCS before being reimbursed for services rendered. Providers suspended as a result of a Medicare action must appeal through the Medicare office before applying for re-enrollment with Medi-Cal. In accordance with W&I Code, section 14043.61, subdivision (a), a provider of health care services shall be subject to suspension if claims for payment are submitted under any provider number used by the provider to obtain reimbursement from the Medi-Cal program for the services, goods, supplies or merchandise provided, directly or indirectly to a Medi-Cal beneficiary, by an individual or entity that is suspended, excluded or otherwise ineligible because of a sanction to receive, directly or indirectly, reimbursement from the Medi-Cal program and the individual or entity is listed on either the _Medi-Cal Suspended and Ineligible Provider List_ (S&I List) published by DHCS to identify suspended and otherwise ineligible providers, or any list published by the federal Office of Inspector General regarding the suspension or exclusion of individuals or entities from the federal Medicare and Medicaid programs, to identify suspended, excluded or otherwise ineligible providers. Examples of providers who need to be aware of the provisions of this law, and could be suspended if violating the law are: 1. Billing services that submit claims for Medi-Cal providers who are suspended; 2. Pharmacies that fill prescriptions and bill for services prescribed by a suspended provider; 3. Providers who bill for services under referral or prescription of a provider who is suspended; 4. Providers who employ and submit claims for the services of an individual who is a suspended provider; 5. Physician groups, clinics and institutions that employ and submit claims for the services of an individual who is a suspended provider; 6. Any individuals or entities that enter into a business arrangement and submit claims for or in conjunction with an individual or entity that is suspended. Always refer to the S&I List when verifying ineligibility. Eligibility or ineligibility must also be verified through the Health and Human Services (HHS) Federal Office of Inspector General (OIG) [List of Excluded Individuals/Entities](https://oig.hhs.gov/exclusions/exclusions_list.asp). Cross-referencing both lists is recommended to help identify providers who have already been suspended or sanctioned. The S&I List is not all inclusive. Temporary sanctions against providers are not included on the web sites. Temporary sanctions that may be imposed include temporary suspensions, withhold of payments and deactivation.

DWR continuous groundwater level measurements contains continuous time-series data from automated recorders at sites operated by the Department of Water Resources. Readings are taken at 15-minute to one-hour intervals. Some of the readings are relayed to the California Data Exchange Center. However, most of the monitoring sites are visited once every month or two, when readings are off-loaded from data recorders, then finalized and published. Wells monitored for this dataset are located within Butte, Colusa, Glenn, Mendocino, Modoc, Sacramento, San Joaquin, Shasta, Siskiyou, Solano, Sutter, Tehama, Yolo, and Yuba Counties. Water-level measurements are the principal source of information about changes in groundwater storage and movement in a basin, and how these are affected by various forms of recharge (e.g., precipitation, seepage from streams, irrigation return) and discharge (e.g., seepage to streams, groundwater pumping). Water-level monitoring involves "continuous" or periodic measurements. Continuous monitoring makes use of automatic water-level sensing and recording instruments that are programmed to make scheduled measurements in wells. This provides a high-resolution record of water-level fluctuations. Resulting hydrographs can accurately identify the effects of various stresses on the aquifer system and provide measurements of maximum and minimum water levels in aquifers. Continuous monitoring may be the best technique to use for monitoring fluctuations in groundwater levels during droughts and other critical periods when hydraulic stresses may change at relatively rapid rates, or when real-time data are needed for making water management decisions [see usgs reference](https://ca.water.usgs.gov/sustainable-groundwater-management/groundwater-levels-california.html).

__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.

[Technical Notes] The dataset contains hospitalization counts and rates, statewide and by county, for 12 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; perforated appendix; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; dehydration; bacterial pneumonia; urinary tract infection; angina without procedure (retired, 2016); uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall, acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

The dashboard is updated each Friday. __Laboratory surveillance data__: California laboratories report SARS-CoV-2 test results to CDPH through electronic laboratory reporting. Los Angeles County SARS-CoV-2 lab data has a 7-day reporting lag. Test positivity is calculated using SARS-CoV-2 lab tests that has a specimen collection date reported during a given week. Specimens for testing are collected from patients in healthcare settings and do not reflect all testing for COVID-19 in California. Test positivity for a given week is calculated by dividing the number of positive COVID-19 results by the total number of specimens tested for that virus. Weekly laboratory surveillance data are defined as Sunday through Saturday. __Hospitalization data__: Data on COVID-19 and influenza hospital admissions are from Centers for Disease Control and Prevention’s (CDC) National Healthcare Safety Network (NHSN) Hospitalization dataset. The requirement to report COVID-19-associated hospitalizations was effective November 1, 2024. CDPH pulls NHSN data from the CDC on the Wednesday prior to the publication of the report. Results may differ depending on which day data are pulled. Admission rates are calculated using population estimates from the P-3: Complete State and County Projections Dataset (https://dof.ca.gov/forecasting/demographics/projections/) provided by the State of California Department of Finance. Reported weekly admission rates for the entire season use the population estimates for the year the season started. For more information on NHSN data including the protocol and data collection information, see the CDC NHSN webpage (https://www.cdc.gov/nhsn/index.html). Weekly hospitalization data are defined as Sunday through Saturday. __Death certificate data__: CDPH receives weekly year-to-date dynamic data on deaths occurring in California from the CDPH Center for Health Statistics and Informatics. These data are limited to deaths occurring among California residents and are analyzed to identify COVID-19-coded deaths. These deaths are not necessarily laboratory-confirmed and are an underestimate of all COVID-19-associated deaths in California. Weekly death data are defined as Sunday through Saturday.

This dataset contains fecal indicator bacteria (FIB) monitoring results collected from surface waters across California. It includes results for _Escherichia coli_ (E. coli), enterococci, fecal coliforms, and total coliforms - key indicators used to assess microbial water quality and potential health risks associated with recreational water use. The data has been cleaned and standardized to ensure consistency and usability. For each valid data point, the dataset also includes calculated 6-week and 30-day geometric means, which are commonly used to evaluate long-term water quality trends and compliance with bacteria water quality objectives. Some records are excluded from the final dataset during processing. These typically include duplicate or replicate results, records with missing or invalid result values, or any data that cannot be used to calculate a geometric mean. These records are saved to the "Excluded Records" data resource. This dataset serves as the primary data source for the Water Boards My Water Quality Portal [Safe to Swim Map](https://mywaterquality.ca.gov/safe-to-swim/content/interactive_map/index.html), which provides the public with timely information about potential health risks associated with water contact recreation at monitored sites. Data is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN) database, BeachWatch database, and the Central Valley Water Board [Lower American River Recreational Water Quality Map](https://experience.arcgis.com/experience/47e27f245e044ac2a8e15083307e75f6/?draft=true&org=waterboards). There is some overlap with the [CEDEN Water Chemistry dataset](https://data.ca.gov/dataset/surface-water-chemistry-results). Both portal datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map.

Borehole extensometers are a more site specific method of measuring land subsidence. These instruments consist of a pipe or cable anchored at the bottom of a well casing. Pipe or cable extend from the bottom of the well, through geologic layers susceptible to compaction, to the ground surface. The pipe or cable is connected to a recorder that measures the relative distance between the bottom of the bore hole to the ground surface. These instruments are capable of detecting changes in land surface elevation to 1/100th of a foot. When land subsidence and water depth monitoring activities are paired together, hydraulic and mechanical properties of the aquifer system can be determined. DWR monitors 11 extensometers in the Sacramento Valley. For more information regarding land subsidence monitoring vist: http://www.water.ca.gov/groundwater/landsubsidence/LSmonitoring.cfm

Draft Coarse Grid California Central Valley Groundwater-Surface Water Simulation Model (released January 1, 2026). C2VSimCG v2025 is a computer program that simulates water movement through the linked land surface, groundwater, and surface water flow systems in California’s Central Valley from October 1973 through September 2015. The C2VSimCG model contains monthly historical stream inflows, surface water diversions, precipitation, land use, and crop acreages. C2VSimCG dynamically calculates crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumping required to meet the remaining demand. It simulates the historical response of the Central Valley’s groundwater and surface water flow system to historical stresses and can also be used to simulate the response to projected future stresses. The C2VSimCG version 2025 model package includes model input files, GIS data, model report and a short document describing how to run the model.

This feature contains the spatial representation of public fishing piers, jetties and breakwaters defined in Section 1.88 of Title 14, California Code of Regulations (CCR). Public piers must be connected to the shoreline, allow for free, unrestricted public access, and have been built or currently function for the primary purpose of fishing. Publicly owned jetties and breakwaters may also be "public piers" but, in addition, must form the most seaward protective boundary of an ocean harbor. Jetties and other structures that are not the most seaward boundary are not public piers. Even though a fishing license is not required on a public pier, all other regulations (including minimum size, bag limits, report cards, and seasons) apply while fishing from a public pier. Additionally, only two rods and lines, handlines, or nets, traps, or other appliances used to take crabs may be used per person on a public pier (CCR Title 14, Section 28.65(b)). PLEASE NOTE: CDFW cannot guarantee that individual piers, jetties, or breakwaters will be open to the public. The landowner may close these areas for safety, maintenance, or other reasons at any time. Attributes: Pier: Common name/identifier of public fishing location, County: County where fishing location is located, Lat_ddm: Latitude of fishing location in degrees decimal minutes, Long_ddm: Longitude of fishing location in degrees decimal minutes, Notes: Any special considerations or closures associated with the fishing location.

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.

This dataset provides data for new prescription drugs introduced to market in California with a Wholesale Acquisition Cost (WAC) that exceeds the Medicare Part D specialty drug cost threshold. Prescription drug manufacturers submit information to HCAI within a specified time period after a drug is introduced to market. Key data elements include the National Drug Code (NDC) administered by the FDA, a narrative description of marketing and pricing plans, and WAC, among other information. Manufacturers may withhold information that is not in the public domain. Note that prescription drug manufacturers are able to submit new drug reports for a prior quarter at any time. Therefore, the data set may include additional new drug report(s) from previous quarter(s). There are two types of New Drug data sets: Monthly and Annual. The Monthly data sets include the data in completed reports submitted by manufacturers for calendar year 2025, as of January 12, 2026. The Annual data sets include data in completed reports submitted by manufacturers for the specified year. The data sets may include reports that do not meet the specified minimum thresholds for reporting. The program regulations are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/CTRx-Regulations-Text.pdf The data format and file specifications are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/Format-and-File-Specifications-version-2.0-ada.pdf DATA NOTES: Due to recent changes in Excel capabilities, it is not recommended that you save these files to .csv format. If you do, when importing back into Excel the leading zeros in the NDC number column will be dropped. If you need to save it into a different format other than .xlsx it must be .txt Submitted reports that are still under review by HCAI are not included in these files. DATA UPDATES: Drug manufacturers may submit New Drug reports to HCAI for prescription drugs which were not initially reported when they were introduced to market. CTRx staff update the posted datasets monthly for current year data and as needed for previous years. Please check the 'Data last updated' date on each dataset page to ensure you are viewing the most current data.

This data table reports the monthly number of deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

The dataset contains hospitalization counts and rates, statewide and by county, for 10 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; community-acquired pneumonia; urinary tract infection; uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI (formerly OSHPD) only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

The data is sorted by counties and cities. Structural Performance Categories (SPC ratings) are also provided. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. Where SPC ratings have not been confirmed by the Department of Health Care Access and Information (HCAI) yet, the rating index is followed by 's'. A URL for the building webpage in HCAI/FDD eServices Portal is also provided to view projects related to any building.

Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a structural performance category (SPC). SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by 2020 and all SPC 2 buildings to be removed from providing general acute care services by 2030. Therefore, a hospital facility that may be comprised of a number of hospital buildings meets the 2020 requirements if there are no SPC 1 buildings on campus. A hospital facility meets the 2030 requirements if all the buildings on campus are either SPC 3, 4 or 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

This data table reports the provisional monthly number of deaths that occurred in California regardless of the place of residence (by occurrence). __Provisional counts are based on the records available when the data was retrieved, given by Data\_Extract\_Date, and may not represent all deaths that occurred during the time period.__ Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death. Cause of death categories for years 1999 and later are based on tenth revision of International Classification of Diseases (ICD-10) codes. Comparable categories are provided for years 1979 through 1998 based on ninth revision (ICD-9) codes. For more information on the comparability of cause of death classification between ICD revisions see [Comparability of Cause-of-death Between ICD Revisions](https://www.cdc.gov/nchs/nvss/mortality/comparability_icd.htm).

The Groundwater Sustainability Plan (GSP) Annual Report (AR) datasets contain the following data submitted by Groundwater Sustainability Agencies (GSA) and Alternative Agencies as part of their GSP AR or Alternative to GSP AR: groundwater extraction, surface water supply, total water use, and change in storage volumes for a given water year. All data was originally submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s AR Modules (https://sgma.water.ca.gov/portal/gspar/submitted and https://sgma.water.ca.gov/portal/alternative/annualreport/submitted). Data records within each dataset correspond to either an entire basin or one of multiple GSP areas which collectively correspond to an entire basin. The GSP Regulations established the AR data requirements (23 CCR § 356.2) and tasked DWR with developing an online reporting system for GSAs and Alternative Agencies to electronically submit these data (23 CCR § 353.2). The data fields associated with these datasets were created by DWR to ensure GSAs and Alternative Agencies electronically submitted the required AR data to DWR’s online reporting system, the SGMA Portal (https://sgma.water.ca.gov/portal/). For additional information regarding the AR Modules and the AR submittal process, please view the DWR’s AR resources (https://sgma.water.ca.gov/portal/resources).

The California Department of Public Health (CDPH) is coordinating with wastewater utilities, local health departments, academic researchers, and laboratories in California on wastewater surveillance for infectious disease pathogens of interest to public health (such as SARS-CoV-2, the virus causing COVID-19, influenza, respiratory syncytial virus (RSV), mpox, and norovirus). Data collected from this network of participants, called the California Surveillance of Wastewaters (Cal-SuWers) Network, are submitted to the U.S. Centers for Disease Control and Prevention (CDC) National Wastewater Surveillance System (NWSS). Collecting and analyzing wastewater samples for the presence of, and amount of (concentration), a specified pathogen target can help inform public health about circulation of that infectious disease within a community. Data from wastewater testing do not replace existing public health surveillance systems but complement them. While wastewater surveillance cannot determine the exact number of infected persons in the area being monitored, it can provide overall trends of pathogen concentration within that community. Please note that data included in the Cal-SuWers Network and available here originate from multiple programs and laboratories. Methodologies for producing wastewater data are not currently standardized, and analyses, comparisons, and aggregations should be done with caution. Wastewater is a complex environmental sample and inherent variability in measured concentrations is expected due to environmental variability, day-to-day differences in sewershed and population dynamics, differences in the amount of shedding between people and pathogens, and laboratory and sampling variability. Please see the CDPH Cal-SuWers, CDC NWSS, and CDC Public Health interpretation and Use of Wastewater Surveillance data webpages for more information. Historical wastewater data can be found [here](https://data.ca.gov/dataset/covid-19-wastewater-surveillance-data-california).

This dataset identifies the total number of individuals that have been admitted to and released from CDCR custody in monthly increments as of January 31, 2014 to present. Note: On June 30, 2021, the Admissions data methodology was changed and is now calculated based upon the date the offender was placed in the California Department of Corrections and Rehabilitation’s custody instead of the start date of the offender’s prison term.
This data provides results from field analyses, from the [California Environmental Data Exchange Network](https://ceden.org/) (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.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering.

This data table reports the statewide annual number of deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

This dataset contains counts of deaths for California counties based on information entered on death certificates. Final counts are derived from static data and include out-of-state deaths 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 deaths that occurred during the time period. Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The final data tables include both deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence), whereas the provisional data table only includes deaths that occurred in each county regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by age, gender, race-ethnicity, and death place type. Deaths due to all causes (ALL) and selected underlying cause of death categories are provided. See temporal coverage for more information on which combinations are available for which years. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death.

The nation spends billions annually on preventable hospitalizations.[1] This indicator provides the rates of preventable hospitalizations (per 100,000 population) for selected conditions. It is based upon a composite indicator for twelve ambulatory care-sensitive conditions. Examples include diabetes complications, adult asthma, hypertension, heart failure, dehydration, urinary tract infection, and bacterial pneumonia. Hospitalizations due to these conditions are potentially preventable through access to high-quality outpatient care.[1] Learn more at [Let's Get Healthy California](https://letsgethealthy.ca.gov/goals/redesigning-the-health-system/reducing-preventable-hospitalizations/) [1] Preventable Hospitalization in California: Statewide and County Trends in Access to and Quality of Outpatient Care, Measured with Prevention Quality Indicators (PQIs), 1999-2008.

The DWR Periodic Groundwater Levels dataset contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. This resource also included daily measurements from DWR's automated monitoring network of groundwater sites. For DWRs holdings of groundwater level measurements recorded at more frequent intervals (e.g., hourly), please refer to DWR's “Continuous Groundwater Level Measurements” dataset. For additional information regarding DWR groundwater levels data collection please visit DWR's Groundwater Management website (https://www.water.ca.gov/Programs/Groundwater-Management). The source data can also be accessed directly from two websites. The Water Data Library (http://wdl.water.ca.gov) provides anonymous access to this and other data sets. The CASGEM online system (https://www.casgem.water.ca.gov/OSS) provides authenticated access to only the the periodic groundwater measurements. This dataset is maintained primarily in the DWR Enterprise Water Management database and contains information specific to the location of groundwater level monitoring wells and groundwater level measurements collected at these wells. The Stations resource identifies well location coordinates and other supplementary items about the well type. Measurements resources includes information about the time/date a measurement was collected, the entity collecting the measurement, a measurement indicating the depth to groundwater, and quality information about the measurement. The Well Perforations resources contains well construction information identifying the well's screened intervals (not available for all wells).

The California Department of Public Health (CDPH) aggregates confirmed cases of COVID-19 by sewershed restricted locations. Confirmed cases are defined as individuals with a positive molecular test, which tests for viral genetic material, such as a polymerase chain reaction test. Since wastewater data available starts from January 1st, 2021, rather than the beginning of the COVID-19 pandemic in 2020, the cumulative counts of the confirmed cases variable are shown as “NA”. Please note that values less than 5 for confirmed cases are masked (shown as “Masked”) if the sewershed population size is 50,000 or fewer, in accordance with de-identification guidelines. Values less than 3 for cases are masked (shown as “Masked”) if the sewershed population size is between 50,001 and 250,000. For no confirmed cases reported, values are set as zero.
This data table reports the annual number of deaths that occurred in each California county regardless of the place of residence (by occurrence) and deaths to residents of each California county (by residence). The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed will affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not take into account contributing causes of death.

This is a point feature class of environmental monitoring stations maintained in the California Department of Water Resources’ (hereafter the Department) Water Data Library Database (WDL) for discrete “grab” water quality sampling stations. The WDL database contains DWR-collected, current and historical, chemical and physical parameters found in drinking water, groundwater, and surface waters throughout the state. This dataset is comprised of a Stations point feature class and a related “Period of Record by Station and Parameter” table. The Stations point feature class contains basic information about each station including station name, station type, latitude, longitude, and the dates of the first and last sample collection events on record. The related Period of Record Table contains the list of parameters (i.e. chemical analyte or physical parameter) collected at each station along with the start date and end date (period of record) for each parameter and the number of data points collected. The Lab and Field results data associated with this discrete grab water quality stations dataset can be accessed from the California Natural Resources Agencies Open Data Platform at https://data.cnra.ca.gov/dataset/water-quality-data or from DWR’s Water Data Library web application at https://wdl.water.ca.gov/waterdatalibrary/WaterQualityDataLib.aspx

This database represents structures impacted by wildland fire that are inside or within 100 meters of the fire perimeter. Information such as structure type, construction features, and some defensible space attributes are determined as best as possible even when the structure is completely destroyed. Some attributes may have a null value when they could not be determined. Fire damage and poor access are major limiting factors for damage inspectors. All inspections are conducted using a systematic inspection process, however not all structures impacted by the fire may be identified due to these factors. Therefore, a small margin of error is expected. Two address fields are included in the database. The street number, street name, and street type fields are “field determined.” The inspector inputs this information based on what they see in the field. The Address (parcel) and APN (parcel) fields are added through a spatial join after data collection is complete. Additional fields such as Category and Structure Type are based off fields needed in the Incident Status Summary (ICS 209). Please review the DINS database dictionary for additional information.

This dataset contains counts of deaths for California as a whole based on information entered on death certificates. Final counts are derived from static data and include out-of-state deaths 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 deaths that occurred during the time period. Deaths involving injuries from external or environmental forces, such as accidents, homicide and suicide, often require additional investigation that tends to delay certification of the cause and manner of death. This can result in significant under-reporting of these deaths in provisional data. The final data tables include both deaths that occurred in California regardless of the place of residence (by occurrence) and deaths to California residents (by residence), whereas the provisional data table only includes deaths that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by age, gender, race-ethnicity, and death place type. Deaths due to all causes (ALL) and selected underlying cause of death categories are provided. See temporal coverage for more information on which combinations are available for which years. The cause of death categories are based solely on the underlying cause of death as coded by the International Classification of Diseases. The underlying cause of death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." It is a single value assigned to each death based on the details as entered on the death certificate. When more than one cause is listed, the order in which they are listed can affect which cause is coded as the underlying cause. This means that similar events could be coded with different underlying causes of death depending on variations in how they were entered. Consequently, while underlying cause of death provides a convenient comparison between cause of death categories, it may not capture the full impact of each cause of death as it does not always take into account all conditions contributing to the death.
This dataset is comprised of data submitted to HCAI by prescription drug manufacturers for wholesale acquisition cost (WAC) increases that exceed the statutorily-mandated WAC increase threshold of an increase of more than 16% above the WAC of the drug product on December 31 of the calendar year three years prior to the current calendar year. This threshold applies to prescription drug products with a WAC greater than $40 for a course of therapy. Required WAC increase reports are to be submitted to HCAI within a month after the end of the quarter in which the WAC increase went into effect. Please see the statute and regulations for additional information regarding reporting thresholds and report due dates. Key data elements in this dataset include the National Drug Code (NDC) maintained by the FDA, narrative descriptions of the reasons for the increase in WAC, and the five-year history of WAC increases for the NDC. A WAC Increase Report consists of 27 data elements that have been divided into two separate Excel data sets: Prescription Drug WAC Increase and Prescription Drug WAC Increase – 5 Year History. The datasets include manufacturer WAC Increase Reports received since January 1, 2019. The Prescription Drugs WAC Increase dataset consists of the information submitted by prescription drug manufacturers that pertains to the current WAC increase of a given report, including the amount of the current increase, the WAC after increase, and the effective date of the increase. The Prescription Drugs WAC Increase – 5 Year History dataset consists of the information submitted by prescription drug manufacturers for the data elements that comprise the 5-year history of WAC increases of a given report, including the amount of each increase and their effective dates. There are two types of WAC Increase datasets below: Monthly and Annual. The Monthly datasets include the data in completed reports submitted by manufacturers for calendar year 2025, as of January 12, 2026. The Annual datasets include data in completed reports submitted by manufacturers for the specified year. The datasets may include reports that do not meet the specified minimum thresholds for reporting. The Quick Guide explaining how to link the information in each data set to form complete reports is here: https://hcai.ca.gov/wp-content/uploads/2024/03/QuickGuide_LinkingTheDatasets.pdf The program regulations are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/CTRx-Regulations-Text.pdf The data format and file specifications are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/Format-and-File-Specifications-version-2.0-ada.pdf DATA NOTES: Due to recent changes in Excel, it is not recommended that you save these files to .csv format. If you do, when importing back into Excel the leading zeros in the NDC number column will be dropped. If you need to save it into a different format other than .xlsx it must be .txt Submitted reports that are still under review by HCAI are not included in these files. DATA UPDATES: Drug manufacturers may submit WAC Increase reports to HCAI for price increases from previous quarters. CTRx staff update the posted datasets monthly for current year data and as needed for previous years. Please check the 'Data last updated' date on each dataset page to ensure you are viewing the most current data. Due to regulatory changes that went into effect April 1, 2024, reports submitted prior to April 1, 2024, will include the data field "Unit Sales Volume in US" and reports submitted on or after April 1, 2024, will instead include "Total Volume of Gross Sales in US Dollars".

This dataset supports the [SWAMP Data Dashboard](https://gispublic.waterboards.ca.gov/swamp-data/), a public-facing tool developed by the [Surface Water Ambient Monitoring Program](https://www.waterboards.ca.gov/water_issues/programs/swamp/) (SWAMP) to provide accessible, user-friendly access to water quality monitoring data across California. The dashboard and its associated datasets are designed to help the public, researchers, and decision-makers explore and download monitoring data collected from California’s surface waters. This dataset includes five distinct resources: * __SWAMP Stations__ – Geospatial and descriptive information about SWAMP monitoring sites. * __Water Quality Results__ – Field and lab analysis results for chemical and physical parameters measured in water samples. * __Toxicity Summary Results__ – Summarized results from aquatic toxicity tests. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water. * __Habitat Results__ – Data on physical habitat conditions typically collected alongside biological monitoring to provide context for interpreting water quality conditions. Includes scores for the California Stream Condition Index (CSCI) and Algal Stream Condition Index (ASCI). * __Tissue Summary Results__ – Annual summary statistics of contaminant concentrations in aquatic organism tissue samples. The data are derived from raw individual and composite tissue sample results. These data are collected by SWAMP and its partners to support water quality assessments, identify trends, and inform water resource management. The SWAMP Data Dashboard provides interactive visualizations and filtering tools to explore this data by region, parameter, and more. The SWAMP dataset is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN), which serves as the central repository for water quality data collected by various monitoring programs throughout the state. As such, there is some overlap between this dataset and the broader CEDEN datasets also published on the California Open Data Portal (see Related Resources).
