California Health Interview Survey (CHIS) Annual Data Release

Health impacts of gambling. Housing discrimination. Voter engagement. Medical debt. Climate change and mental health. Medi-Cal access among immigrants.

These are just a few of the topics that will be featured during the California Health Interview Survey (CHIS) annual data release on Thursday, October 3, 2024.

Join us as UCLA Center for Health Policy Research (CHPR) Director and CHIS Principal Investigator Ninez A. Ponce, PhD, MPP, and CHIS Director Todd Hughes share brand new data from the 2023 survey.

Ponce and Hughes will discuss some of the most notable findings and new topics, including a fact sheet examining gambling among Californians and some of the associated health behaviors and risks.

The 2023 CHIS features more than 50 new topics and questions, including housing discrimination, prescription painkiller use, unintended pregnancy, access to filtered air during wildfire smoke, adolescent college plans, adolescent sexual orientation, and child gender identity. The full list of topics and questionnaires are available on the CHIS Questionnaires and Survey Topics page.

For the last 23 years, UCLA CHPR has produced the California Health Interview Survey, which collects information from more than 20,000 California households on a wide range of health matters: from use of and access to health care, to health conditions and behaviors. CHIS also covers a wide range of topics that influence health: public program participation, housing, income and employment, climate change, food insecurity, fears of gun violence, hate incidents, adverse childhood experiences, and more topics and factors that influence health outcomes. CHIS data, made available to the public via AskCHIS, can be viewed across sociodemographic factors such as race and ethnicity, gender, age, sexual orientation and gender identity, and income level.

The largest population-based state health survey in the nation, CHIS provides policymakers, legislators, local health departments, community organizations, researchers, health experts, advocates, members of the media, and the public access to credible and comprehensive data to provide a detailed picture of the health and health care needs of California’s large and diverse population.
