A new study confirms what I have argued before: most of the race gap today is really a family gap.
Black wages have grown, and the black middle class proportion has grown. If that was all that had happened, the racial income gap would have been cut substantially - at least in half - in the past half century.
Instead, the gap has remained the same over all.
This is largely because the proportion of black children growing up in single parent families has grown from about 25% in 1965 to more than 70% today. These families are poorer than their two-parent counterparts, and the children who grow up in them are handicapped in gaining economic security as they grow up and make families themselves.
I thank Claude Fischer's fine blog for bringing a new study by Deirdre Bloom on this point to our attention.
