Where a country counts another spelling of the name rather than Orsen itself, the figure is that spelling’s, and it is named. 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.
