PRB analysis of data from the Centers for Disease Control and Prevention, National Center for Health Statistics microdata files. Data for California come from supplemental Internet tables within the published report, Births: Final Data.

N.A. - Data not available.

Data are provided for the 50 most populous cities according to the most recent Census counts. Cities for which data are collected may change over time.

Beginning in 2018, due to state statutory restrictions, California no longer provides record-level data on the marital status of the mother for births occurring in California to California residents and non-residents (including residents of other states). Due to this change, data for selected cities are not available.
