Babies given each name, 1880–2025
Masatoshi Massimo
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 61 years in which either name was published, Massimo for 59 years and Masatoshi for 2 years. The lead changed hands once.

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 Masatoshis alive today are over 106; half the Massimos are over 11. That is 95 years between them: two names in use at the same time, worn by two different generations.
