Spontaneous Labor | Induced Labor | |

Vaginal | 11001 | 2761 |
Unscheduled Cesarean | 1045 | 656 |
Scheduled Cesarean | 110 | 300 |
Excluding scheduled cesareans from the table above, there were 12046 spontaneous labors and 3417 inductions. 9% of the spontaneous labors ended in cesarean and 19% of the inductions ended in cesarean.
Some people have looked at these numbers, and the fact that there seems to be an increase in cesareans after 40W0D, and wondered if there's a correlation. In other words, do "timeline-based" inductions lead to increased cesareans? That analysis gets tricky, so I'll just post the numbers and let you decide yourself what's going on.
