Users are able to access data related to a variety of health outcomes, including health status, health conditions, health-related behaviors, health care access and health insurance coverage information. The California Health Interview Survey is maintained by the UCLA center for Health Policy Research. The California Health Interview Survey is targeted to three specific age groups:  adults, adolescents (12-17), and children (birth-11). CHIS is conducted every two years with many core questions 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. CHIS is available in 5 languages.

These public data files contain records of individual respondents (age, gender, race, rural/urban), health status data, health conditions data, health-related behaviors data, health care access data and health care coverage information. In order to minimize the risk of indirect identification and increase data confidentiality sub-state geographic information and information on sexual behavior are excluded from the public access files. Users are able to find more detailed information by contacting the Data Access Center. In order to access the files you must submit an online application available on the website. Costs for individual projects vary and students may be able to receive scholarships. The website also offers specific FAQs and help for questions accessing data.
