Births in the United States, 2020
Abstract:
This report presents selected highlights from 2020 final birth data on key demographic, health care utilization, and infant health indicators. General fertility rates (births per 1,000 women aged 15-44), age-specific birth rates (births per 1,000 women in specified age group), low-risk (nulliparous, term, singleton, cephalic births) cesarean delivery, and preterm (less than 37 weeks of gestation) birth rates are presented. All indicators are compared between 2019 and 2020 and shown for all births. General fertility rates (GFRs), lowrisk cesarean and preterm birth rates are shown for the three largest race and Hispanic-origin groups: non-Hispanic white, non-Hispanic black, and Hispanic. Fertility rates are shown by age of mother.
