Selected data by mother's state of residence and birth rates by age also are shown. Trend data for 2010 through 2018 are presented for selected items. Trend data by race and Hispanic origin are shown for 2016-2018. Results-3,791,712 births were registered in the United States in 2018, down 2% from 2017.
