California Health Interview Survey releases local-level health data

The California Health Interview Survey, led by principal investigator Dr. Ninez Ponce, UCLA Fielding School of Public Health professor of health policy and management, has published new estimates at the city, ZIP code, legislative district, and census tract levels

Thursday, July 21, 2022

The UCLA Center for Health Policy Research has updated its health data query tool, AskCHIS Neighborhood Edition™ (NE), with new topics and 2020 small area estimates that provide specific health and demographic data on Californians at progressively finer levels of magnification: legislative district, county, city, ZIP code, and census tract.
Drawing upon the responses of more than 20,000 households in California interviewed each year by the California Health Interview Survey (CHIS), AskCHIS NE provides data on various health topics: chronic conditions such as asthma and diabetes, delays in receiving medical care, health and mental health status, physical activity, food insecurity, and more. The new update, which includes data from the 2019–2020 CHIS, features two new indicators related to smoking: secondhand smoke exposure and flavored tobacco use.
Using a sophisticated modeling technique called Small Area Estimation (SAE), AskCHIS NE provides local health departments, policymakers, legislators, community organizations, researchers, and other stakeholders the data needed to target health interventions based on a neighborhood’s specific needs.
