# data is premliminary.
Primary rate is the number of 1st Cesarean Sections per 100 deliveries to women who did not have a previous Cesarean Section. For 2005 this data is broken down by states that have not adopted the 2003 revision (37), those who adopted in 2004 (7), and those that did so in 2005 (12).
Repeat rate is the proportion of all Cesarean Sections that are repeat cesareans.
VBAC rate is the rate/per 100 = number who had a Cesarean Section in the past and now had a successful vaginal delivery. For 2005 this data is broken down by states that have not adopted the 2003 revision (37), those who adopted in 2004 (7), and those that did so in 2005 (12).
