Stacy was most popular in 1971, when 10,144 American babies were given the name — ranking #65 that year. In 2025 it ranked #2,821, with 140 births. Across 1880–2025 the Social Security Administration has recorded 186,268 people named Stacy.
The Social Security Administration’s records begin in 1880, and Stacy 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 137 of the 146 years since.
The Social Security Administration has recorded 186,268 American births named Stacy 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 172,459 are estimated to be alive today.
140 American babies were named Stacy in 2025, ranking #2,821 that year.
Stacy is falling. Across 2021–2025 it averaged 163 births a year, against 255 a year across 2011–2015 — a change of -36% 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 Stacy is mostly a girl’s name — 88.0% of the 186,268 Americans given it were girls and 12.0% were boys. It changed hands: since 1952 it has gone mainly to girls, having gone mainly to boys before that. In births since 2016 it is 91% girls and 9% 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 172,459 Americans named Stacy are alive today — 93% of everyone ever recorded with the name. The median is 51 years old, and half are between 44 and 57.
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.
