Deaths and tests source data

Data notes
  • All daily averages are 7-day averages.
  • For death data after December 31, 2022, California uses Provisional Deaths from the Center for Disease Control and Prevention’s National Center for Health Statistics (NCHS) National Vital Statistics System (NVSS). Prior to January 1, 2023, death data was sourced from the COVID-19 registry.
  • The change in data source occurred in July 2023 and was applied retroactively to all 2023 data to provide a consistent source of death data for the year of 2023.
  • Hospitalized patients include all patients diagnosed with COVID-19 during their stay. This does not necessarily mean they were hospitalized because of COVID-19 complications or that they experienced COVID-19 symptoms.
  • New admissions counts include patients who were admitted to an inpatient bed on the previous calendar day who had laboratory-confirmed COVID-19 at the time of admission.
  • Death daily average and rate have a 22-day lag due to delays in reporting.
  • Tests have a 1-day lag.
  • The population denominators used for the per 100K rates come from the California Department of Finance’s population projections for 2020.
  • Test positivity is based on a 7-day average with no lag. Data is provided by the California Department of Public Health.
  • Looking for case data? Archived historical case data is available on the Open Data Portal.

COVID-19 hospitalized patients and ICU source data. Data is updated weekly.

Chart information
  • Hospitalization counts include all patients diagnosed with COVID-19 during their stay. This does not necessarily mean they were hospitalized because of COVID-19 complications or that they experienced COVID-19 symptoms.
  • Suspected COVID-19 patient data is available in the hospitalized patients and ICU source data.
  • More details about hospitalized and ICU patients, including patients suspected of having COVID-19, are available in the hospitalization dashboard.
  • The “ICU Beds” chart will be truncated and only have data starting from 05/11/2023. This is due to differences in data collection between the new federal standard (NHSN) and the previous California standard (CHA).
