Low Risk C-Sections

PeriStats now has data on low risk C-Sections. A low-risk cesarean section occurs when a woman undergoes a cesarean section procedure when the baby is a single infant, is positioned head-first and the mother is full-term (at least 37 weeks), and has not given birth prior.1

Low-risk cesarean section rates were calculated as the number of cesarean section procedures that occurred to first-time mothers of a single infant, positioned headfirst with a gestational age of at least 37 weeks (NTSV) divided by the number of first-time mothers of a single infant, positioned headfirst with a gestational age of at least 37 weeks (NTSV) multiplied by 1,000.

Low-risk cesarean section rates were calculated using the National Center for Health Statistics 2017-2019 final natality data.2

This data can be accessed under the topic "Delivery Method" for state and national levels. Additionally, one can filter low risk C-Sections by maternal age, maternal race and maternal race/ethnicity.
