Definition: Number of deaths among children under age 1 per 1,000 live births (e.g., in 2022, the infant mortality rate in California was 4 infant deaths per 1,000 births).
Data Source: California Dept. of Public Health, Birth and Death Statistical Master Files & California Vital Data (Cal-ViDa) Query Tool; California Dept. of Finance, Population Estimates and Projections; CDC WONDER Online Database, Linked Birth / Infant Death Records (Apr. 2023).
Footnote: County-level data reflect the county of residence, not the county in which the birth or death occurred. The notation S refers to rates that have been suppressed because there were 10 or fewer infant deaths, and to numbers and rates that have been suppressed to protect confidentiality. The annotation [!] indicates that the rate is based on more than 10 but fewer than 20 infant deaths. N/A means that data are not available.
