Babies given each name, 1880–2025
Marilyn Marylynn
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
Marilyn has been the commoner name in every year either was published, 1899 to 2025. The lead has never changed hands.
The closest they came was 1988, when Marilyn had 552 and Marylynn had 47.

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.
