About this dataset and its counting rules

Statistics count the spelling “WILHELMUS” as recorded by the publisher. When a spelling has several independent origins, the counts are not split between them. Counts measure births. Gaps are years without a published value, not zeros.

Rates per million are unavailable for this series because no compatible denominator has been imported.

Universe: Dataset record, verbatim: « List of male and female baby names in South Australia from 1944 to 2024. The annual data for baby names is published January/February each year. » Files used: the 1944-2013 archive (female_/male_cyYYYY_top.csv) and the 2014-2017 per-year CSVs (2016: the 'amended' files).
Rounding: No rounding stated; amounts are integers (valueStatus=observed).
Suppression: No threshold is stated by the publisher. The lists include names with an Amount of 1 (see notes), i.e. no minimum-count suppression is visible; whether the lists are complete is not stated (the linked metadata document returned an error). Absence of a name is 'not listed', never zero.
Ranking: Position as published, preserved verbatim; never recomputed. A leading '=' marks a tie (stored as the number after '='); see notes for the observed pattern.
