HOW IT WORKS
The chart is the number of US babies given the name each year, from the Social Security Administration’s public baby-name files (names given to 5+ babies in a year). The “all-time high” is the name’s biggest year. “Holders” and “median holder age” are rough estimates that apply average US survival rates to each birth year, so they ignore immigration and name changes.
