The 42-year story

Today's parents encounter it on its way down the popularity curve, which for many parents is exactly the appeal. Following the curve matters more than today's snapshot: a name's position on its rise-peak-decline arc is the best predictor of how common it will feel in a kindergarten class five years from now.
