share of that year’s births on record
Births in France by year of birth, from INSEE’s fichier des prénoms (1900–2025; Mayotte from 2012); exact spellings count separately (Léo and Leo are different names), any spelling under 3 in a year and sex is withheld at source, every count is rounded to the nearest 5 at source, and nametree keeps the spellings that reached 20 in some year. Shares divide by INSEE’s count of births in France from 1957, and before that by the file’s own total for the year; INSEE says the file is not complete before 1946.

Not on 13 other recordsWhy
- Not on the record in Mexico City, Argentina, 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 Chile record: nametree keeps spellings that reached 5 registrations 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.
