Births by education level, 2016

What is interesting about this is that education aids in married fertility, but a little goes a long way.  Completing a level of education corresponds to lower out of wedlock birth rate regardless of how high the level of education is.

Thus in a lot of ways, simply having people complete the highest level they reasonably can of education would be a better way to structure the educational system and allow for more options to enter the workforce successfully at younger ages.  This would probably have a side effect of increasing marriage before 25 in a way that favored long-term marital stability.
