Interesting that the article could not see fit to produce even a single graph to show their data. In my experience, there are plenty of educated black women, they have degrees and such, yet often still do not always speak anymore intelligent than others! And there are plenty of black women NOT educated.
It may be that there has been such a dearth of black women in fields requiring degrees that now is the opportunity for many to get into college fields, while other groups have already reached their saturation.
