Where the name is found, darker where our sources hold more of it. No national register counts its bearers anywhere we hold data, so the map carries no figures. Countries with no figure are shown too: flat where a national register lists the name without counting it, hatched where only our records hold it. One hue, darker where it is more common; hover a country for its figure.

About this data

measured from records inferred from the name graph machine-generated

These figures come from the data snapshot of and will change as it is rebuilt.

Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.

Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
