Overview
The California Health Interview Survey (CHIS) is a telephone survey that uses a random-digit-dial (RDD) design for a sample that is representative of the state's population.
Geographic groups
CHIS data can be analyzed at the county level for the state's 41 most populated counties. The remaining 17 counties are combined into 3 different groups. See numbers below.
Age groups
CHIS asks questions that are shared across age groups and also some questions that are unique to only one age group: children (0-11 years of age), adolescents (12-17 years of age), and adults (18 years and older). See numbers below.
Race/ethnicity groups
By including disproportionately higher sampling of many ethnic groups, the CHIS data has greater ability to report on racial/ethnic differences. See numbers below.
