California Health Interview Survey (CHIS) Annual Data Release

California is home to 39 million residents, each of whom has unique health and health care experiences and needs. In order to make a difference, we need reliable data.

Enter the California Health Interview Survey (CHIS).

For more than 20 years, CHIS has played a crucial role in shaping health policies, interventions, and programs by providing comprehensive, up-to-date information on the health of Californians. CHIS gives policymakers, advocates, health care providers, community organizations, researchers, journalists, and other stakeholders the information they need to assess different aspects of health, identify health inequities, and then fight for policies that can improve the lives of Californians through better health and health care.

Join the UCLA Center for Health Policy Research (CHPR) on Wednesday, October 4, 2023, as we release the full 2022 CHIS data and highlight key findings. UCLA CHPR Director and CHIS Principal Investigator Ninez A. Ponce, PhD, MPP, and CHIS Director Todd Hughes, will walk through some of the notable results on topics including: access to care, mental health, health insurance, hate incidents, food insecurity, intimate partner violence, and COVID-19. Sean Tan, MPP, senior public administration analyst, will also share findings from a new fact sheet on telehealth and the future of health care access in California.

The largest population-based state health survey in the nation, CHIS interviews more than 20,000 households each year on a wide range of health topics, including: access to and use of health care, health insurance, health status, health conditions (asthma, diabetes, cancer, etc.), health behaviors (smoking, alcohol use, diet, etc.), COVID-19, mental health, oral health, immigrant health, intimate partner violence, food insecurity, child care, caregiving, discrimination, climate change, and much more.
