Kerstin over time
How old is the name Kerstin?
Kerstin first appears in Social Security Administration records in 1950, which makes it about 75 years old as a recorded American name. It has been recorded in 68 of the 76 years since.
How many people are named Kerstin?
The Social Security Administration has recorded 2,537 American births named Kerstin 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 2,445 are estimated to be alive today.
How many babies were named Kerstin in 2025?
Kerstin 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 Kerstin getting more or less popular?
Kerstin is too rare for a direction to mean much. It averaged 5 births a year across 2021–2025 against 13 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.
Is Kerstin a boy’s or a girl’s name?
Across the whole record Kerstin is a girl’s name — 100.0% of the 2,537 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.
How old is someone named Kerstin?
Roughly 2,445 Americans named Kerstin are alive today — 96% of everyone ever recorded with the name. The median is 35 years old, and half are between 27 and 48.
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.
