The 145-year story

Mack first appears in the Social Security records in 1880, when 104 boys received the name. Its peak came in 1942, when 840 boys were named Mack — good for #190 that year. Today's parents encounter it as a name from their grandparents’ generation, which is precisely the vintage window from which names get revived. 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.
