About the National Data
Data
Baseline: 25.9 percent of low-risk females with no prior birth had a cesarean birth in 2018
Target: 23.6 percent
Methodology
A low-risk female is defined as nulliparous (never given birth before), full-term (at least 37 weeks of gestation, based on obstetric estimate of gestation at delivery), singleton (not a multiple) pregnancy, with a vertex fetus (head facing in a downward position in the birth canal).
Data for the obstetric estimate measure are based on the 2003 U.S. Standard Certificate of Live Birth item "Obstetric estimate of gestation." The obstetric estimate of gestation is defined as "the best obstetric estimate of the infant's gestation in completed weeks based on the birth attendant's final estimate of gestation".
