Babies given each name, 1880–2025
Diego Diem
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.

Diego has been the commoner name in every year either was published, 1887 to 2025. The lead has never changed hands.
The closest they came was 1983, when Diego had 275 and Diem had 24.

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 Diegos alive today are over 18; half the Diems are over 12. That is 6 years between them: two names in use at the same time, worn by two different generations.

Every spelling a country files separately is added together, over whatever years that country publishes — which is not the same range in any two of them, so read the columns against each other and not the rows.
