About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of births delivered by cesarean section to low-risk females with a prior cesarean birth
Number of live births to low-risk females with a prior cesarean birth
A low-risk female is defined as one with a full-term (at least 37 weeks since the first day of the last normal menstrual period [LMP]) singleton (not a multiple) pregnancy, with a vertex fetus (head facing in a downward position in the birth canal). A description of the primary measurement used to determine the fetus’s gestational age, the interval between the first day of LMP and the birth has been published by NCHS.
