How to read these figures

An absent observation is not zero: small counts are withheld, and no published count may mean no births or a suppressed count. Early years are less complete. Recorded sex is a source category, not a rule about who may use a name. Annual ranks order published counts, with alphabetical tie-breaking. National and state totals need not match.

These records describe usage. They do not establish a name’s meaning, origin, ethnicity or pronunciation.
