Katlin was most popular in 1993, when 395 American babies were given the name — ranking #1,098 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 5,461 people named Katlin.
Katlin first appears in Social Security Administration records in 1981, which makes it about 44 years old as a recorded American name. It has been recorded in 35 of the 45 years since. It was last recorded in 2015.
The Social Security Administration has recorded 5,461 American births named Katlin 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 5,366 are estimated to be alive today.
Katlin 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.
Katlin is out of use. It averaged 14 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.
Across the whole record Katlin is a girl’s name — 97.7% of the 5,461 Americans given it were girls and 2.3% 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.
Roughly 5,366 Americans named Katlin are alive today — 98% of everyone ever recorded with the name. The median is 32 years old, and half are between 27 and 35. That is a narrow band: Katlin 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.
