Babies given each name, 1880–2025
Jun Junius
Each line is every baby given the name that year, girls and boys added together — the only count that means the same thing for both names. A line breaks where the name fell below five babies in a year — the point at which the SSA stops publishing it — rather than being drawn through a figure nobody published. A single published year in a gap shows as a dot.
Who was ahead
Of the 146 years in which either name was published, Junius for 104 years and Jun for 42 years. The lead changed hands 9 times.

A rank is a position within one sex’s list for one year, so the two rank rows are not subtracted from one another and the winning column is not marked on them. The living figure is a life-table estimate, not a count.
Which name is older
Half of the Juniuses alive today are over 60; half the Juns are over 22. That is 38 years between them: two names in use at the same time, worn by two different generations.
