Retain evidence type, year, sample and rank when quoting observations. These are not national birth totals.

The July 2026 snapshot is the dataset refresh month, not a July birth cohort or a live monthly popularity ranking.
The latest ranking evidence is from 2025; the source is a named commercial survey sample, not a national census.
Reading-ranking examples are labeled separately and must not be interpreted as full written-name positions.
Documented-name examples establish an editorial example, not a ranking or frequency.
Missing records or ranks mean the pair is not in this reviewed export; they do not prove that a name was absent from a source survey.
