30 people counted by IBGE — Censo 2022 Nomes no Brasil per-token lookup (v3 API, given+surname).

A dash means neither exists.

Registers cited: RENAPER — Apellidos (person counts, national); IBGE — Censo 2022 Nomes no Brasil per-token lookup (v3 API, given+surname); the italian-surnames-defelice-1978 register; BFS — Familiennamen der Wohnbevölkerung (surnames); Familienaam.be — Belgian family-name frequency (population register).

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.
