CHIS COVID-19 Preliminary Estimates Dashboard

The California Health Interview Survey (CHIS), the nation's largest state health survey, has once again released early estimates to shed light on the impact of COVID-19 on Californians. The dashboard, which includes data from surveys conducted from February through August 2022, features brand new questions on long COVID, child/teen vaccination rates, reasons for not getting the vaccine or booster, and where they receive their COVID news and information. Additional questions include hate incidents and other COVID impacts among Asian Americans, Native Hawaiians, and Pacific Islanders, adherence to state and local guideines, personal and financial impacts of the pandemic, and more. Topics can be filtered by race/ethnicity, poverty level, citizenship status, and more to provide a detailed picture of the effects of COVID-19 on our most vulnerable communities.

COVID-19 Dashboards

UCLA CHPR has created several tools to track COVID-19 and various risk factors such as chronic diseases and underlying conditions, insurance status, food insecurity, and more by California county. We hope that these dashboards will help illuminate factors related to COVID-19 occurrences and vulnerabilities and can be used for decision-making on targeting health and economic support policies across California communities.
