Frequently asked questions
- Is Ηώ a male or female name?
- Ηώ 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 which country does Ηώ have the most bearers?
- In the United States, the national register counted about 322 people named Io, more than in any other country we hold.
- Where is Ηώ most common?
- No national register we hold counts the spelling Ηώ itself. The densest figure for its family of spellings is Cyprus's: the national register counts about 1 in 106 thousand people named Ιω.
- How common is the name Ηώ?
- In the United States, the national register counted 322 people named Io in 2020, about 1 in 1.0 million residents.

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.
