Strategic Plan for Asthma in California

​Asthma in California Report

Two reports are available. The 2017 report focuses on asthma prevalence, whereas the 2013 report is comprehensive (includes asthma prevalence, disparities, morbidity, mortality, environmental triggers, emergency department visits, hospitalizations, work-related asthma, and national goals). Also available for download are slides that summarize report findings and provide easy-to-use graphs and charts. Reports include the following:

  • Asthma rates over time and by age, sex, race/ethnicity, and other characteristics
  • Comparisons of California's rates to national goals
  • Data on asthma prevalence, morbidity, and health care utilization and quality
  • Special sections on environmental risk factors and work-related asthma
