Super-black names

As someone inclined to name my children odd things, I was fascinated by this article on disparities in baby naming among blacks and whites, based on foirty years of California census data. Money:

Today, more than 40 percent of the black girls born in California in a given year receive a name that not one of the roughly 100,000 baby white girls received that year. Even more remarkably, nearly 30 percent of the black girls are given a name that is unique among every baby, white and black, born that year in California. (There were also 228 babies named Unique during the 1990s alone, and one each of Uneek, Uneque, and Uneqqee; virtually all of them were black.)

What kind of parent is most likely to give a child such a distinctively black name? The data offer a clear answer: an unmarried, low-income, undereducated, teenage mother from a black neighborhood who has a distinctively black name herself. Giving a child a super-black name would seem to be a black parent's signal of solidarity with her community—the flip side of the "acting white" phenomenon. White parents, meanwhile, often send as strong a signal in the opposite direction. More than 40 percent of the white babies are given names that are at least four times more common among whites.

The article also claims that toting a "super-black" name doesn't actually inhibit your "life outcome," a term left curiously undefined.
