The Social Security Administration’s records begin in 1880, and Harmon 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 6,642 American births named Harmon 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 2,259 are estimated to be alive today.
20 American babies were named Harmon in 2025, ranking #10,279 that year.
Harmon is holding steady. Across 2021–2025 it averaged 23 births a year, against 24 a year across 2011–2015 — a change of -5% 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 Harmon is a boy’s name — 0.5% of the 6,642 Americans given it were girls and 99.5% were boys. In births since 2016 it is 9% girls and 91% 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 2,259 Americans named Harmon are alive today — 34% of everyone ever recorded with the name. The median is 59 years old, and half are between 24 and 75. 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.
