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 Rosario is a unisex name — 66.2% of the 16,585 Americans given it were girls and 33.8% were boys. It changed hands: since 1938 it has gone mainly to girls, having gone mainly to boys before that. In births since 2016 it is 78% girls and 22% 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 11,969 Americans named Rosario are alive today — 72% of everyone ever recorded with the name. The median is 44 years old, and half are between 26 and 62. 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.
