Definition: Percentage of infants born to mothers who received prenatal care during the first three months of pregnancy (e.g., among births to California mothers in 2021, 86.8% were to mothers who had received first trimester prenatal care).
Data Source: California Dept. of Public Health, California Vital Data (Cal-ViDa) Query Tool and Birth Statistical Master Files (Jun. 2022).
Footnote: County-level data reflect the mother's county of residence, not the county in which the birth occurred. Percentages are calculated on the basis of total births, which include cases with missing prenatal care information. The notation S refers to percentages that have been suppressed because there were fewer than 20 births to mothers receiving first trimester prenatal care, and to numbers that have been suppressed because there were fewer than 11 births to mothers receiving first trimester prenatal care.
