Arcadia Arcadio

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 109 years in which either name was published, Arcadio for 78 years and Arcadia for 31 years. The lead changed hands 17 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 Arcadios alive today are over 42; half the Arcadias are over 16. That is 26 years between them: two names in use at the same time, worn by two different generations.
