Ivo Ivori

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 98 years in which either name was published, Ivo for 64 years and Ivori for 34 years. The lead changed hands 15 times.

10 shorter spells of a year or two are folded into the spans above rather than listed separately.

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 Ivos alive today are over 20; half the Ivoris are over 11. That is 9 years between them: two names in use at the same time, worn by two different generations.
