How many people are named Haydyn?
The Social Security Administration has recorded 599 American births named Haydyn 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 593 are estimated to be alive today.
How many babies were named Haydyn in 2025?
Haydyn 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.
Is Haydyn getting more or less popular?
Haydyn is falling. Across 2021–2025 it averaged 10 births a year, against 30 a year across 2011–2015 — a change of -67% 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.
Is Haydyn a boy’s or a girl’s name?
Across the whole record Haydyn is a unisex name — 51.2% of the 599 Americans given it were girls and 48.8% were boys. It changed hands: since 2018 it has gone mainly to girls, having gone mainly to boys before that. In births since 2016 it is 64% girls and 36% 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.
How old is someone named Haydyn?
Roughly 593 Americans named Haydyn are alive today — 99% of everyone ever recorded with the name. The median is 16 years old, and half are between 12 and 19. That is a narrow band: Haydyn 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.
