Babies given each name, 1880–2025
Jon Jonita
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
Jon has been the commoner name in every year either was published, 1898 to 2025. The lead has never changed hands.
The closest they came was 1924, when Jon had 61 and Jonita had 6.

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.
