Roughly 2.2M people in United States bear this name (about 1 in 149). Estimates project the name's share of our records onto national population, so each is only as good as the record base beside it — the Basis column gives that base; rows marked △ rest on fewer records than the estimate itself and are order-of-magnitude at best.

About this data
Data snapshot . Figures are rebuilt periodically and will change.
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.
