How old the living Arlos are
born that year still alive today
Of the 25,135 babies given the name since 1899, about 23,000 are alive — 90 in every hundred. Roughly 21,000 of them are children and 490 are 65 or over. The dotted line is the median: half were born before 2021 and half after.
An estimate, not a count. SSA births aged forward through SSA cohort life tables, which know nothing about who left the country or arrived in it — so for a name that mostly came to America rather than being born in it, this is a floor rather than a figure. Where you fall among living Americans.

Counts come from each country's own records and are not comparable with the US figures above, which cover different years and a different definition of a recorded name. Where a country writes the name several ways, the spellings are added together and the most common is shown. A row marked name registrations is counting something else: Portugal ranks each of a child's two given names separately, so a girl registered Maria Leonor is in both the Maria row and the Leonor row, and that figure is not a number of children.

By canton, Arlo is most concentrated in Zurich, where 0.01% of children were given it – 31 of them.
Arlo: rank by region
In 2025, Arlo was given 5 times or more in 1 region of Belgium.
| Region | Spelling | Place | Children |
|---|---|---|---|
| Flanders | Arlo | 180 | 32 |
In 2024, Arlo was given 2 times or more in 1 region of Poland.
| Region | Spelling | Place | Children |
|---|---|---|---|
| Małopolskie | Arlo | 241 | 2 |
In 2025, with the country taken in 11 areas rather than 3, Arlo appears in the lists for Province of East Flanders (132nd), Province of West Flanders (138th) and Province of Antwerp (290th).
Each of these is the top of a list the statistics office cut off somewhere – Belgium below 5 children, Poland below 2 children – and published nothing after. So a region missing here is one where the name fell outside what was published, not one where it went unused. Places are shared where names tie, and the further down a list a place is, the more names can share it.
Arlo by city
| City | Years | Births | Best rank |
|---|---|---|---|
| Berlin boys | 2017–2023 | 14 | 360th |
| Berlin girls | 2017–2023 | 2 | 548th |
One city over a few years, so these are much smaller numbers than the national ones above and not comparable with them.
Arlo among the living
How many people each country's register counts under the name, rather than how many were given it in any one year. Each register was read on one date, and they are not the same date.
| Country | Spelling | First forename | Any forename |
|---|---|---|---|
| Finland boys | Arlo | 94 | 115 |
| Finland girls | Arlo | 5 | 6 |
A count of people on a register – Finland on 4 August 2026 – and not of births, so it cannot be compared with the figures above. Names with very few bearers are withheld, and a dash in the first-forename column means the register would not say rather than that nobody goes by it.

Source: US Social Security Administration, national and state baby-name files, 1880–2025. Counts include only births registered with the SSA, and names with fewer than five births in a year are not published. The living estimate applies SSA cohort life tables to those births; it counts people born in the United States, so it misses anyone who arrived later and anyone who has left.
