Ottilia Otto

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

Otto has been the commoner name in every year either was published, 1880 to 2025. The lead has never changed hands.

The closest they came was 1891, when Ottilia had 22 and Otto had 279.

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 Ottos alive today are over 9; half the Ottilias are over 4. That is 5 years between them: two names in use at the same time, worn by two different generations.

Both names abroad

Countries whose statistics office publishes both names, so the comparison can be made somewhere other than the United States.

Country Ottilia Otto
England and Wales 964,283
France 151,020
Switzerland 19131

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.
