] The California data establish just how dissimilarly black
] and white parents have named their children over the past
] 25 years or so -- a remnant, it seems, of the Black
] Power movement. The typical baby girl born in a black
] neighborhood in 1970 was given a name that was twice as
] common among blacks than whites. By 1980, she received a
] name that was 20 times more common among blacks. (Boys'
] names moved in the same direction but less
] aggressively -- likely because parents of all races are
] less adventurous with boys' names than girls'.) 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.)
