The Social Security Administration’s records begin in 1880, and Milo 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 44,313 American births named Milo 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 38,290 are estimated to be alive today.
2,995 American babies were named Milo in 2025, ranking #213 that year.
Milo is rising. Across 2021–2025 it averaged 3,028 births a year, against 1,075 a year across 2011–2015 — a change of +182% 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 Milo is a boy’s name — 1.1% of the 44,313 Americans given it were girls and 99.0% were boys. In births since 2016 it is 1% girls and 99% 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 38,290 Americans named Milo are alive today — 86% of everyone ever recorded with the name. The median is 7 years old, and half are between 4 and 13. That is a narrow band because Milo 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.
