Otho over time
How old is the name Otho?
The Social Security Administration’s records begin in 1880, and Otho 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 104 of the 146 years since. It was last recorded in 1991.
How many people are named Otho?
The Social Security Administration has recorded 3,328 American births named Otho 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 519 are estimated to be alive today.
How many babies were named Otho in 2025?
Otho 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 Otho a boy’s or a girl’s name?
Across the whole record Otho is a boy’s name — 0.0% of the 3,328 Americans given it were girls and 100.0% were 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 Otho?
Roughly 519 Americans named Otho are alive today — 16% of everyone ever recorded with the name. The median is 73 years old, and half are between 62 and 82.
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.
