Dig deep into California health issues with comprehensive statewide data files on a variety of topics using AskCHIS. AskCHIS is a tool that allows you to quickly search for health statistics on your county, region and state. AskCHIS draws upon the responses of more than 50,000 Californians interviewed by The California Health Interview Survey (CHIS) – the largest state health survey in the United States. Information is gathered using a random-dial telephone survey conducted every two years on a wide range of health topics. CHIS data gives a detailed picture of the health and health care needs of California’s large and diverse population.
