What are the layers above the arcuate line?

Are black women’s pelvis different?
We found that African-American women have narrower transverse diameters of the bony pelvis than white women (pelvic inlet and intertuberous distance). Also, among women delivering vaginally without a sphincter tear, African-American women had a deeper pelvic anteroposterior diameter (outlet).
Does a small pelvis mean C section?
