Katelin first appears in Social Security Administration records in 1977, which makes it about 48 years old as a recorded American name. It has been recorded in 46 of the 49 years since.
The Social Security Administration has recorded 8,917 American births named Katelin 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 8,775 are estimated to be alive today.
Katelin 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.
Katelin is falling. Across 2021–2025 it averaged 8 births a year, against 57 a year across 2011–2015 — a change of -87% over the decade.
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 Katelin is a girl’s name — 100.0% of the 8,917 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.
Roughly 8,775 Americans named Katelin are alive today — 98% of everyone ever recorded with the name. The median is 30 years old, and half are between 24 and 35. That is a narrow band: Katelin arrived and faded within about a decade rather than staying in steady use.
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.
How much more common the name is in each state than across the country as a whole.
