California Health Interview Survey 2018 Data Release

​The CHIS 2018 Data Release seminar is an overview of data from the 2017-2018 California Health Interview Survey (CHIS). Ninez Ponce, Center director, CHIS principal investigator and professor at the UCLA Fielding School of Public Health, and Todd Hughes, CHIS director, will share highlights from the survey, including newly expanded questions on tobacco, marijuana and e-cigarette use, and important findings and trends in key health topics such as health insurance coverage and mental health.

The new data will be available for download through the Public Use Files (PUF) and included in the AskCHIS© data query tool following the webinar. CHIS, the nation’s largest state-based population health survey, interviews approximately 20,000 households each year to represent California’s geographic and ethnic diversity.

Please note that a portion of the video was edited for clarity and data corrections. Please view the presentation slides for updates to slides 25 and 26.
