Babies given each name, 1880–2025
Seneca Senia
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 89 years in which either name was published, Seneca for 61 years and Senia for 28 years. The lead changed hands once.

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 Senecas alive today are over 30; half the Senias are over 24. That is 6 years between them: two names in use at the same time, worn by two different generations.
