Leontine over time
How old is the name Leontine?
Leontine first appears in Social Security Administration records in 1883, which makes it about 142 years old as a recorded American name. It has been recorded in 84 of the 143 years since. It was last recorded in 2015.
How many people are named Leontine?
The Social Security Administration has recorded 1,150 American births named Leontine 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. Of those, roughly 213 are estimated to be alive today.
How many babies were named Leontine in 2025?
Leontine was not recorded in 2025. The SSA withholds any name given to fewer than five babies in a year, so fewer than five American babies were given it.
Is Leontine getting more or less popular?
Leontine is out of use. It averaged 6 births a year a decade ago and has not been recorded in the last five years.
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.
Is Leontine a boy’s or a girl’s name?
Across the whole record Leontine is a girl’s name — 100.0% of the 1,150 Americans given it were girls and 0.0% were 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.
How old is someone named Leontine?
Roughly 213 Americans named Leontine are alive today — 19% of everyone ever recorded with the name. The median is 74 years old, and half are between 60 and 83.
An estimate, not a count. Recorded births are carried forward through the Social Security Administration’s 2023 period life table, by age and sex. That table describes mortality in one recent year, so it credits the oldest cohorts with today’s survival rather than the harsher rates they actually lived through — the further back a name peaked, the more this will overstate how many remain. It counts people issued a Social Security number at birth, not immigrants who arrived later.
