IBGE — names by decade (Kaggle mirror), 2022 on the left; every record we hold for Brazil on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Characteristic of Brazil

Not the most common names — the most distinctive ones. A name appears here when Brazil holds a larger share of its bearers than the world does, weighted by how much of the country's whole name distribution it accounts for.

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.

Questions

What is the most common given name in Brazil?
Lucimar, according to IBGE — names by decade (Kaggle mirror) (2022), with 75,108 bearers recorded.
What is the most common surname in Brazil?
Silva, according to IBGE — Censo 2022 Nomes no Brasil per-token lookup (v3 API, given+surname), with 34,030,104 bearers recorded.

Is there one naming system in Brazil?
No — 2 are described on this page (Portuguese, Tetum), and they are separate systems rather than variants of one.
