Is Erinn getting more or less popular?
Erinn is out of use. It averaged 15 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 Erinn a boy’s or a girl’s name?
Across the whole record Erinn is a girl’s name — 96.0% of the 3,561 Americans given it were girls and 4.0% 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 3,442 Americans named Erinn are alive today — 97% of everyone ever recorded with the name. The median is 40 years old, and half are between 32 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.
