Hover a line for what is available to explain that row.
SURS — resident population given names, 2025 on the left; every record we hold for Slovenia on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Characteristic of Slovenia

Not the most common names — the most distinctive ones. A name appears here when Slovenia holds a larger share of its bearers than the world does, weighted by how much of the country's whole name distribution it accounts for.

The best-attested names in Slovenia, in the spelling our records use there. Where a Latin spelling is also attested it is shown beneath — a spelling from the corpus, not a machine romanisation.

The Latin alphabet here is not the ASCII one. Stripping diacritics merges names that are not the same name and changes how they are pronounced, and a record that has been ASCII-folded has lost information no amount of guessing recovers.

Countries whose names look alike

Measured as the overlap between each country's top 300 given-name forms, weighted by how common each is — the fuzzy-set approach of Lauc (2024), on a truncated inventory.

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.

Questions

What is the most common given name in Slovenia?
Marija, according to SURS — resident population given names (2025), with 43,035 bearers recorded among girls.
What is the most common surname in Slovenia?
Novak, according to stat.si Imena rojstva — full name register (per-token frequency + rank), with 10,510 bearers recorded.
Why do sources disagree about the commonest name in Slovenia?
Because they count different people. SURS — resident population given names (2025) counts one population once, and its commonest given name is Marija. Our corpus counts every record we hold — historical registers, the diaspora, decades of births — and its commonest is Matej. Both are on this page, each with its denominator.
Is there one naming system in Slovenia?
No — 6 are described on this page (Slovenian, Italian, Maltese, Romansh, Sardinian and Corsican, Hungarian), and they are separate systems rather than variants of one.
