How popular is Arn around the world?

Those files omit name-and-sex counts below five, so there is no popularity curve to chart and no basis for saying the name was never used. Arn is not on the 2025 record for Norway, where names carried by fewer than 4 people in a year are withheld at source.

Arn is not on the 2025 record for Norway, where names carried by fewer than 4 people in a year are withheld at source.
share of the boys on the register for that year, SSB’s own figure
People who have or have had a Norwegian ID number, emigrants left out, from Statistics Norway’s name statistics (release of January 2026): by year of birth for 1945–2020 (everyone born that year who was ever registered in Norway, including people who registered later and people who have since died) and by year of naming from 2021; only first names carried by 200 or more living people are listed, counts under 4 are withheld, and SSB merges spellings that differ only by letters outside the Norwegian alphabet. The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.

South Australia
last on record 2012
Arn is not on the 2017 record for South Australia, whose registry publishes every name given that year.
The count never rose above 1 in a year, too few to chart.
Births registered in South Australia (not all of Australia) by first name and year of registration, 1944–2017, from the state’s Births, Deaths and Marriages registry, which publishes every name down to a single birth in capitals; a spelling its export repeats inside a year is counted once, and from 2018 only a top 100 is published, so the series ends at 2017.

Not on 14 other recordsWhy
- Not on the record in Spain, Mexico City, Argentina, Puerto Rico, England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
- Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown.
- Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years.
- Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown.
- Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only).
