First-name registrations with Chile’s civil registry by year of registration, 1920–2021, counted as spelling groups (Sofía, Sofia and Sofìa are one name, shown with its most-registered spelling); the registry withholds nothing, nametree keeps the groups that reached 5 registrations in some year, and shares divide by every registration of the year.

Not on the record in Puerto Rico, England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only). Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
