Statistics count the spelling “Claas” 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
- Published counts for first-position given names of newborn children registered at Berlin's twelve district registry offices. Disjoint common district counts and the citywide pool of district-singleton counts are added; anonymous unique-name totals are excluded.
- Rounding
- Published integer counts retained without rounding.
- Suppression
- District counts of one are moved to a separate pool and combined by spelling/sex/position; pooled counts of one remain anonymous and cannot be assigned to names. Published subtotals can omit singleton contributions even for names published elsewhere. Missing contributions are unknown, never inferred as zero.
- Ranking
- computed by NameStoria from published counts; ties share a rank, next rank skips; ranks describe published position-1 subtotals, not a complete unsuppressed register.
