Definition: Number of deaths among children under age 1 per 1,000 live births (e.g., in 2014-2016, the mortality rate among California infants was 4.3 deaths per 1,000 births).
Data Source: California Dept. of Public Health, Birth and Death Statistical Master Files; National Center for Health Statistics, Linked Birth / Infant Death Records (Feb. 2019).
Footnote: County-level data reflect the county of residence, not the county in which the birth or death occurred. The notation S refers to data that have been suppressed because there were fewer than 20 infant deaths. N/A means that data are not available.
