Brookings has an interesting 'Long Memo' on the marriage problem faced by educated black females. Intermarriage rates are apparently low, and educated black men are far less numerous than educated black women, So the opportunity for 'assortive' mating is low. (I don't know this is particularly a problem beyond couple's future earning potential. On paper my husband is significantly better educated than I am. But the university of life can be a better teacher than some left-wing, indoctrinating, cloistering institution - depending on subject studied.)
Anyway, it was this graph that intrigued me. It shows the significant progress of black females in relation to, not only black males, but white males (I use Brooking's labels for simplicity.) 57 percent of black women have 'some college' or 'bachelor's degree or more' versus 54 percent of white men (within the age group studied).
