Risk of placenta previa and accreta at a cesarean birth by the number of the cesarean birth

Number	Previa (percent)	Accreta (percent)	Accreta in patients with previa (percent)
Second cesarean birth	1.33	0.31	11
Third cesarean birth	1.14	0.57	40
Fourth cesarean birth	2.27	2.13	61
Fifth cesarean birth	2.33	2.33	67
Sixth or greater cesarean birth	3.37	6.74	67

The baseline risk of placenta previa in the general obstetric population is 1 in 200 deliveries. Placenta accreta occurs in fewer than 1 in 500 deliveries.
