The Social Security Administration has recorded 12,481 American births named Baby 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 11,506 are estimated to be alive today.
23 American babies were named Baby in 2025, ranking #9,389 that year.
Baby is rising. Across 2021–2025 it averaged 56 births a year, against 34 a year across 2011–2015 — a change of +62% 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 Baby is a unisex name — 48.9% of the 12,481 Americans given it were girls and 51.1% were boys. It changed hands: since 2023 it has gone mainly to girls, having gone mainly to boys before that. In births since 2016 it is 46% girls and 54% 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 11,506 Americans named Baby are alive today — 92% of everyone ever recorded with the name. The median is 31 years old, and half are between 25 and 35. That is a narrow band: Baby 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.
