California Health Interview Survey (CHIS)

About this Resource

From asthma, diabetes and obesity to immigrant health and the number of Californians with health insurance, CHIS covers dozens of essential health topics. Many core questions are repeated in each survey in order to measure significant shifts over time. New questions are also added each survey year to address emerging concerns that are important for planning and policy development. 

The survey provides:

  • Statewide information on the overall population including many racial and ethnic groups.
  • Local-level information on most counties for health planning and important comparison purposes.
