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. This registry counts each spelling separately; the figures above are for the exact spelling Kaïs, and accented spellings are separate names.

Not on the record in Mexico City, Argentina, Puerto Rico, 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 Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. 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 Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
