About this dataset and its counting rules

Statistics count the spelling “Aloysius” as recorded by the publisher. When a spelling has several independent origins, the counts are not split between them. Counts measure applications. 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: US national Social Security card applications by name, sex and birth year; not a complete birth registry, especially before 1937.
Rounding: Integer application counts retained without rounding.
Suppression: Only names with at least 5 occurrences in a year and sex are included. Missing observations are not zeros.
Ranking: computed by NameStoria from published counts; ties share a rank, next rank skips. The mirror's derived rank column is not used.
