Recorded 1983–2024 · United States
Infant was most popular in 1990, when 1,178 American babies were given the name — ranking #481 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 8,138 people named Infant.
Infant first appears in Social Security Administration records in 1983, which makes it about 42 years old as a recorded American name. It has been recorded in 41 of the 43 years since.
The Social Security Administration has recorded 8,138 American births named Infant 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 7,942 are estimated to be alive today.
Infant 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.
Infant is rising. Across 2021–2025 it averaged 37 births a year, against 10 a year across 2011–2015 — a change of +274% 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 Infant is a unisex name — 48.0% of the 8,138 Americans given it were girls and 52.0% were boys. It changed hands: since 2024 it has gone mainly to boys, having gone mainly to girls before that. In births since 2016 it is 50% girls and 50% 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 7,942 Americans named Infant are alive today — 98% of everyone ever recorded with the name. The median is 31 years old, and half are between 27 and 36. That is a narrow band: Infant 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.
