Recorded 1880–2025 · United States
Ottilia was most popular in 1891, when 22 American babies were given the name — ranking #906 that year. In 2025 it ranked #13,540, with 13 births. Across 1880–2025 the Social Security Administration has recorded 597 people named Ottilia.
The Social Security Administration’s records begin in 1880, and Ottilia is already there in that first year — so the name is older than the record and these figures cannot date it. It has been recorded in 60 of the 146 years since.
The Social Security Administration has recorded 597 American births named Ottilia between 1880 and 2025. That is recorded US births, not a world population — it counts people issued a Social Security number at birth in the United States.
13 American babies were named Ottilia in 2025, ranking #13,540 that year.
Ottilia is too rare for a direction to mean much. It averaged 11 births a year across 2021–2025 against 6 a year a decade earlier — at these counts a single baby moves the percentage, and any year under five births is withheld at source.
Measured on recorded births. American births overall have fallen since 2007, so most established names lose births over any recent decade — a name can shed births and still hold its rank. Compare the rank above, which is measured against the other names of the same year.
Across the whole record Ottilia is a girl’s name — 100.0% of the 597 Americans given it were girls and 0.0% were boys. In births since 2016 it is 100% girls and 0% boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
