This one will be a quickie because state level data is a huge headache to assemble, but nationally, about 20-25% of first births are primary c-sections. About 33% of births each year are c-sections, but the exact amount which are first births varies more year to year. Further, starting that way limits the feasible number of births to no more than 6, with 3-4 being much more typical. After four c-sections, the risk of death to either/both of mom and baby or catastrophic surgery like a preterm c-section/hysterectomy combo gets up to the level of open-heart surgery (well north of 20%, far, far, far higher than the half a percent (.5%) risk of rupture only (not death and not catastrophic surgery, rupture may mean forceps or vacuum delivery for the infant and/or another c-section) for VBAC after one section that leads many hospitals to deny women access to VBAC .
Some women (pretty much all conservative Christian or Mormon women) successfully find a doctor willing to perform the surgery after 4 c-sections, and some of those women die. It’s a small group, so I’m not going to claim you’re guaranteed to die if you have five or six c-sections and zero vaginal deliveries. So few women “go there” it’s not easy to know. But you will struggle to find a doctor to take on your pregnancy past four and increasingly past three sections and you will be very very very strongly pushed to have a hysterectomy or tube tying after the second, third or fourth c-section delivery.
I basically hear zip, zilch, zero about this from conservatives claiming people have smaller families these days due to selfishness and love of money and vacations. You’d think they would pay attention to this sort of massive obstacle to a plurality of women having large families.
