Scripts & spelling
The Latin alphabet here is not the ASCII one. Stripping diacritics merges names that are not the same name and changes how they are pronounced, and a record that has been ASCII-folded has lost information no amount of guessing recovers.

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.
