Darwin first appears in Social Security Administration records in 1881, which makes it about 144 years old as a recorded American name. It has been recorded in 131 of the 145 years since.
The Social Security Administration has recorded 26,436 American births named Darwin 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 17,016 are estimated to be alive today.
241 American babies were named Darwin in 2025, ranking #1,966 that year.
Darwin is holding steady. Across 2021–2025 it averaged 237 births a year, against 261 a year across 2011–2015 — a change of -9% 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 Darwin is a boy’s name — 0.3% of the 26,436 Americans given it were girls and 99.7% were boys. In births since 2016 it is 1% girls and 99% 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 17,016 Americans named Darwin are alive today — 64% of everyone ever recorded with the name. The median is 46 years old, and half are between 17 and 67. That is a wide band, the mark of a name in steady use across generations rather than a passing fashion.
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.
