The California Health Interview Survey (CHIS) is a collaborative project of the UCLA Center for Health Policy Research, the California Department of Health Services, and the Public Health Institute. CHIS is the largest state health survey in the United States. It is a telephone survey conducted every two years on public health topics and access to health care.
By interviewing a large number of people, CHIS can give health planners, policy makers, counties, and communities more detailed picture of the health and health care needs facing California's diverse population. CHIS provides information on where and how people get health care as well as the number of adults and children without health insurance. CHIS also collects information on important health conditions such as cancer, diabetes, and asthma.
CHIS is conducted by the UCLA Center for Health Policy Research in collaboration with the California Department of Health Services (DHS) and the Public Health Institute (PHI). It is funded by both public and private organizations.
