What are the statistics on episiotomy rates that Hilary Erickson emphasizes in her content?

Hilary often emphasizes how much episiotomy rates have come down and that your provider should know (and be willing to share) their own rate.

From the statistics on the site:

• In 2017, the average rate of episiotomies in the U.S. was 7.8%, down from 9.6% the year before (Leapfrog Group data).

This is why there is encouragement to ask your provider what their individual episiotomy rate is and how they decide when it is necessary.

Are you mainly wondering if your own provider’s rate sounds reasonable, or just trying to understand how common episiotomies are in general?
