Culturally Driven Names

Names whose popularity trajectories run past what random drift alone predicts — in the years they've been tracked, a cultural moment is the most likely explanation for the deviation.

In the years they've been tracked, these names' trajectories crossed the 95th-percentile threshold of a random-drift model — the deviation is larger than chance drift comfortably explains. Something specific often happened — a film, a public figure, a moment. (The bucket measures per-name-year deviation from the null, not proof of cause for any single name.)
