Where the two lists disagree
25 of Australian national given names (aggregated state BDM)'s top 25 given names sit five or more places away in our record corpus. Neither ranking is wrong; they count different people.
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 Australia
Not the most common names — the most distinctive ones. A name appears here when Australia 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.
Over time
Up to five names at a time.
Scripts & spelling
Countries whose names look alike
Measured as the overlap between each country's top 300 given-name forms, weighted by how common each is — the fuzzy-set approach of Lauc (2024), on a truncated inventory.

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.
