Does anyone know where I can find statistics on births at however many week in the U.S?

I want to know % wise how many women actually reach the 40 week mark. I'm also curious to know how many women deliver sooner and how many (those poor unfortunate ladies) go past their due dates...


Anyone know where I can find statistics like these? Thanks!
