Thierry Thimothy

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 76 years in which either name was published, Thierry for 41 years and Thimothy for 35 years. The lead changed hands 4 times.

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 Thimothys alive today are over 57; half the Thierrys are over 18. That is 39 years between them: two names in use at the same time, worn by two different generations.

Both names abroad

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.
