About this dataset and its counting rules

Statistics count the spelling “Guglielmo” 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: Annual first given names of newborns, BEVNAT live-birth statistics, national geography 8100 only. Infostar civil-register data. Regional rows are not added to national totals.
Rounding: Published integer counts retained without rounding.
Suppression: Only names and cells published in the FSO flows are covered. Literal zero cells are not emitted; absence in NameStoria must not be treated as a complete national zero-frequency claim.
Ranking: FSO RANK observations retained unchanged; zero rank/count pairs omitted.
