About this data
measured from records inferred from the name graph machine-generated

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.

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.
