Sepp
Given to 90 babies in Belgium, 2016 to 2025. Every figure below is a count of birth registrations, not an estimate.
By register
By decade, every selected register together
Asked and held nothing for this name: England and Wales (1996–2025), Scotland (1974–2025), Ireland (1964–2025), Norway (1945–2025), Sweden (1998–2022), France (1900–2023), Poland (2000–2025), Canada (1991–2024), Argentina (2012–2024), Finland (living citizens, 2026), Greenland (2002–2025). That is not a count of nought — each of those registers was searched and does not carry this spelling. Every one withholds its smallest counts, on its own rule, so a name can be real there and still absent from what they publish.
Narrow these tables
The sum at the top of each table adds counts that were not made on the same rule — the Americans publish a name only where five or more babies were given it in a year, ONS redact any name given to two or fewer in total, Finland counts living citizens rather than births. It is an indication of how widely the name is recorded, not a measurement of how many people have it.
How it is said
sˈɛp
From the CMU Pronouncing Dictionary, free for any use. The symbols are IPA, converted from CMU's notation by the published correspondence. Two things in that conversion are ours rather than theirs: an unstressed vowel is written as a schwa, and the stress mark sits before the stressed vowel rather than at the start of its syllable — CMU record no syllable boundaries, so placing it properly would mean guessing where the syllables fall.
Where these numbers come from
United States, 1880 to 2025
As a boy's name, Sepp was registered 5 times in the United States between 2010 and 2019, most often in the 2010s.
England and Wales
Not in this register. Sepp does not appear in the English and Welsh figures for 1996 to 2025. ONS withhold any name given to two or fewer babies in total, so this means the name was rare there rather than unknown.
Scotland
Not in this register. Sepp does not appear in the Scottish figures for 1974 to 2025. NRS suppress any name given to two or fewer babies in a year, so this means the name was rare there rather than unknown.
Northern Ireland
On the register, with the number withheld. Sepp appears in the Northern Irish figures in 1 year, and NISRA publish no count for any of them: the name went to fewer than three babies in each of those years, and they withhold the number rather than the name. That is not a count of nought — it is a name somebody was given.
NISRA fold accents before publishing, in their words: “Names containing accents have been recorded without those accents.” Only Scotland does the same. So a Northern Irish figure covers every accenting of a name and most of the figures beside it do not.
Ireland
Not in this register. Sepp does not appear in the Irish figures for 1964 to 2025. The CSO list a name once it has reached three babies in any single year, so this means the name never did.
Norway
Not in this register. Sepp does not appear in the Norwegian figures for 1945 to 2025. SSB list only names used by at least two hundred people in the previous year, so an absence here usually means the name was never that common in Norway rather than never used.
Sweden
Not in this register. Sepp does not appear in the Swedish figures for 1998 to 2022. SCB published a name only where at least two babies of that sex were given it, and at least ten before 2004, so this means the name never cleared that bar.
France
Not in this register. Sepp does not appear in the French figures for 1900 to 2023. Insee list a name individually only where it was given at least 20 times to one sex, over 1900-1945 or over 1946-2023; rarer names are pooled into a single record they call _PRENOMS_RARES. So this means the name was rare there rather than unknown.
Belgium
Counted, but not dated. Sepp was given to 90 babies in Belgium, and not one of those births has a year published against it. Statbel publish one ten-year total per municipality and no year column at all, so there is nothing to date these births to. This is the whole of what they publish for this name.

Belgium is the only register here with no years in it, so it appears on every page as a single figure. And that figure is a sum of municipal counts that each reached five on their own — a floor with a hole in the middle rather than at the edge.
Austria, 1984 to 2025
16 babies, from a register that begins in 1984. Its decades cannot be compared with the American ones, which reach back to 1880: where the two tables above put them in the same row, they are counting different lengths of record.
Source: Statistik Austria. Licensed under Creative Commons Attribution 4.0. The registers withhold small counts on different rules — Statistik Austria withhold no count at all — where a name was given fewer than four times in a year they withhold the district instead, and publish the number, and the Americans hide one given to fewer than five in a year — so a name in one table and not another may only have met different thresholds.
Austria is the only column on this page that is a total rather than a floor: nothing is held back except which district a birth was in. Two things do limit it. It records first names only, so a child registered Anna Maria is an Anna. And its coverage widens twice — to 2009 it counts only babies with Austrian citizenship, from 2010 every baby born in Austria, and from 2015 also babies born abroad to mothers living there — so the later decades are larger partly by rule and not only by naming.
Austrian spellings are also partly folded. Statistik Austria transcode names so that spellings alike but for their marks come together, and the only marks that survive are the six German umlauts. So an Austrian figure for an unaccented spelling covers the accented ways of writing it as well, and the figures beside it do not.
Switzerland, 2000 to 2025
20 babies, from a register that begins in 2000. Its decades cannot be compared with the American ones, which reach back to 1880: where the two tables above put them in the same row, they are counting different lengths of record.
Source: Federal Statistical Office. Open use, source must be provided. The registers withhold small counts on different rules — the Federal Statistical Office withhold no count either — the smallest figure they publish is one baby — but they do not list every name, and about one Swiss baby in ten is given a name that is not on their list, and the Americans hide one given to fewer than five in a year — so a name in one table and not another may only have met different thresholds.
Switzerland suppresses no figure at all — a Swiss count of one is published as one — so what is missing here is never a small number. It is a name. The published lists hold 2,724 boys’ names and 2,628 girls’ names, against Austria’s 23,938 for a country of much the same size, and no rule is given for what puts a name on them. Rather than guess at the rule, here is the size of it measured: those names account for 69,993 of the 78,153 births the office reports for 2025.
Poland
Not in this register. Sepp does not appear in the Polish figures for 2000 to 2025. the Ministry left out any name given fewer than five times in a year up to 2012, and fewer than two from 2013. So an absence in the early years is a weaker statement than an absence in the later ones.
Canada
Not in this register. Sepp does not appear in the Canadian figures for 1991 to 2024. Statistics Canada publish a name only where five or more babies were given it in a year, and exclude single-letter names, so this means the name was rare there rather than unknown.
Argentina
Not in this register. Sepp does not appear in the Argentine figures for 2012 to 2024. RENAPER publish a figure only where a name was given to at least two people, so this means it was rarer than that, or was given only outside 2012–2024.
Finland
Not in this register. Sepp does not appear in the Finnish figures at all. DVV publish a name only where at least five living Finnish citizens hold it, so this means fewer than five do — not that no Finn was ever given it.
Greenland
Not in this register. Sepp does not appear in the Greenlandic figures for 2002 to 2025. Statistics Greenland suppress nothing, so — as with Austria — this means no resident of Greenland born since 2002 has the name, rather than that it was too rare to print.
The Social Security Administration publish the name on every United States birth registration from 1880 onward, and dedicate the data to the public domain under CC0. This page adds nothing to it: the counts are theirs, grouped by decade.
One gap, and it matters here more than anywhere. SSA publish a name only where five or more babies were given it in a year. A name you cannot find is not a name nobody used — it is a name used four times or fewer, and no site built on this data can see it.
The pronunciation above comes from the CMU Pronouncing Dictionary, which covers some names and not others. Meanings are not here yet. When they arrive they will come from named scholarship old enough to be out of copyright, and where two authorities disagree the page will say so rather than picking one.
