California Asthma Dashboard

Please Note: Due to shrinking federal funds, California Breathing will no longer update the California Asthma Dashboard. California Breathing is partnering with Tracking California, a program of the Public Health Institute that mobilizes data to identify and understand pollution and disease. Tracking California provides asthma data in an interactive online data tool called the Data Explorer Tool.

​Asthma data sets are also available for download from the California Health and Human Services (CHHS) Open Data Portal.

Welcome to the California Asthma Dashboard. Here, you can view state- and county-level asthma data, print PDFs of charts, and download data sets for analysis. The interactive dashboard is organized into four sections:

  1. Statewide data (all asthma measures) – state-level data on asthma prevalence (proportion of the population with asthma), emergency department (ED) visits, hospitalizations, insurers, and deaths
  2. Prevalence by county – county-level data on asthma prevalence (proportion of the population with asthma)
  3. ED visits, hospitalizations, and insurers by county – county-level data on asthma ED visits, hospitalizations, and insurers
  4. Deaths by county – county-level data on asthma deaths

Dashboard Instructions (PDF) | Notes about the Data (PDF) | ADA Accessible Data File (Excel) | Data Analysis Files on Open Data Portal webpage | Additional Resources for Asthma Data (PDF)

*Note: The ADA Accessible Data File is not appropriate for data analysis because all fields are text. To download data sets for analysis, open Data Analysis Files on Open Data Portal webpage or go to the Download Charts and Data Sets section of the dashboard.
