Babies given each name, 1880–2025
Arn Arnoldo
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
Arnoldo has been the commoner name in every year either was published, 1914 to 2025. The lead has never changed hands.
The closest they came was 1949, when Arn had 7 and Arnoldo had 22.

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 Arns alive today are over 69; half the Arnoldos are over 38. That is 31 years between them: two names in use at the same time, worn by two different generations.
