AskCHIS™

The California Health Interview Survey asks the questions. AskCHIS™ gives you the answers.

AskCHIS™ is a free online health query system that allows users to quickly search for health statistics by county, region, and state. Drawing upon the responses of 20,000+ Californians interviewed each year by the California Health Interview Survey (CHIS), AskCHIS™ provides reliable data on a wide range of topics across many sociodemographic factors.

Data can be viewed on screen in tables, charts, and graphs, emailed, and also exported as Excel files. AskCHIS™ includes data beginning in 2001, so users can look at patterns and trends across two decades.
