Definition: Number of births to mothers ages 19 and under, per 1,000 young women ages 19 and under, by age group (e.g., in California in 2021, the teen birth rate among mothers ages 18-19 was 16.9 births per 1,000 young women ages 18-19).
Data Source: California Dept. of Public Health, Birth Statistical Master Files; Centers for Disease Control and Prevention (CDC), Births: Final Data (Mar. 2020); CDC WONDER, Natality; California Dept. of Finance, Population Estimates and Projections (Jun. 2023).
Footnote: County-level data reflect the mother's county of residence, not the county in which the birth occurred. The notation S refers to rates that have been suppressed because there were fewer than 20 births in that group, and to numbers that have been suppressed because there were, depending on the year, fewer than 20 births in that group (2017 and earlier) or between 1 and 9 births in that group (2018 and later). N/A means that data are not available.
