The Social Security Administration’s records begin in 1880, and Isabella is already there in that first year — so the name is older than the record and these figures cannot date it. It has been recorded in 146 of the 146 years since.
The Social Security Administration has recorded 417,454 American births named Isabella 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 406,246 are estimated to be alive today.
10,666 American babies were named Isabella in 2025, ranking #15 that year.
Isabella is falling. Across 2021–2025 it averaged 11,091 births a year, against 17,933 a year across 2011–2015 — a change of -38% 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 Isabella is a girl’s name — 99.9% of the 417,454 Americans given it were girls and 0.1% 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 406,246 Americans named Isabella are alive today — 97% of everyone ever recorded with the name. The median is 15 years old, and half are between 9 and 20. That is a narrow band because Isabella is a young name — it only became common recently, so almost everyone carrying it is still a child or a young adult.
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.
