This dataset reports the number of live births to California residents from 2013-Current. The data are aggregated by mother’s residential ZIP Code. A non-California resident who gives birth inside of California would not be included in this dataset since it is tabulated by mother’s residence and not event occurrence. Conversely, California residents who give birth outside of California are included in this dataset. Birth data at the ZIP Code level can be used to perform small area analysis to identify and target areas within cities and counties where public health programs or school resources may be needed.
