Babies given each name, 1880–2025
Kaelis Kaelyn
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
Kaelyn has been the commoner name in every year either was published, 1959 to 2025. The lead has never changed hands.
The closest they came was 2025, when Kaelis had 45 and Kaelyn had 131.

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 Kaelyns alive today are over 17; half the Kaelises have not had a first birthday. That is 17 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 | Kaelis | Kaelyn |

| France | 5 Kaëlis | 90 |
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.
