California Health Interview Survey: Essential Data for Building Healthier California Communities

The California Health Interview Survey (CHIS) is the most comprehensive source of health information on Californians, and the largest state health survey in the United States.

This fact sheet explains how the survey provides information on a wide range of health topics for California's diverse population, focusing on access to health care, health insurance coverage, health behaviors, chronic health problems, cancer screening and many other relevant health issues. CHIS also provides estimates for a number of California's ethnic/racial groups as well as sexual minorities.
