Exact figures are national registers' own counts, while figures marked ≈ and est. are Mondonomo’s estimates, counted from our sources and calibrated against those registers; hover one for how far to trust it in that country. A dash means neither exists.

Registers cited: DVV — Nimipalvelu (Finnish name service, per-name lookup); Skatteverket — Sök hur många som har ett visst namn (living population); the us-wru-surnames-voterfile register. Figures without a register are Mondonomo estimates; see Methodology.

About this data

measured from records inferred from the name graph machine-generated

These figures come from the data snapshot of 2026-10-10 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.
