Here's a similar phenomenon from the authors of Freakomonics: "...names move through the population from a higher socioeconomic level to a lower level. Levitt and Dubner found “a clear pattern at play: once a name catches on among high-income, highly-educated parents, it starts working its way down the socioeconomic ladder.” When the name is adopted “en masse,” then “high-end parents begin to abandon it,” and presumably, the whole cycle repeats itself with a new batch of names." http://www.babynamesgarden.com/freakonomicswatch.aspx http://www.babynamesgarden.com/freakonomicswatch.aspx They're testing this idea by issuing predictions for popular names in years to come.
