Grouping is the name graph's, not a register's: two spellings join a group when the evidence links them, so a group is a claim about the records rather than about the people.

Is Adaí a male or female name?
Adaí is recorded for both men and women. We don't publish a percentage split: a record's gender belongs to the person and is attached to every given name on that record, so names in cultures where a name string also carries a parent's or spouse's given name pick up large cross-gender counts.

In Brazil, the national register counted about 339 people named Adaí, more than in any other country we hold, where it is most often spelled adai.
Where is Adaí most common?

How common is the name Adaí?

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.
