The news release also mentioned some of the ways in which Estonian pop culture has influenced Estonian baby names recently. Here’s the English translation:

The name Stefan quickly became popular last year. Name choices of famous people can also create trends – Miss Rubi Rahula already has 24 namesakes. After the great Christmas film released in 2018, 22 girls have been named Eia and 43 have been named Jete in the last three years. Last year, nine fans of Kättemaksukontori named their children Lumilee, Lumi Lee or Lumi-Lee.

And here’s some context:

  • Singer Stefan Airapetjan won the first season of the Estonian version of the Masked Singer (2020-).
  • Rubi Rahula (b. 2017) is the daughter of Estonian celebrity (?) couple Anni and Tomi Rahula, whose 2018 book Tule meie juurde (English: Come to us) detailed their struggles with infertility.
  • Eia and Jete were characters in the Estonian children’s adventure film Eia’s Christmas at Phantom Owl Farm (2018).
  • The character Lumi-Lee Aigo was introduced in 2021 on the Estonian comedy-crime TV show Revenge Office (2009-).

In 2020, the top names in Estonia were Sofia and Robin.

And the gender-neutral name Lou managed to pop up on both lists in nearly the same spot: 26th for girls, 27th for boys.

And here’s a selection of names from the other end of the spectrum — names that were given to just 5 babies each in Belgium last year:

Rare Girl NamesRare Boy Names
Anabia, Believe, Caro, Dea, Elaïa, Fallone, Gaby, Heike, Iluna, Jennifer, Kessy, Lyssia, Mahsa, Nihal, Otice, Puck, Queen, Ramla, Siloé, Toos, Vlera, Wassila, Yseult, ZuriAloys, Brandon, Celle, Doruk, Erion, Fedde, Gustav, Hazar, Ilyass, Jip, Karsten, Lothar, Maksim, Nellis, Obi, Paulin, Qays, Riff, Silvio, Tille, Vidar, Wiebe, Yavuz, Zjef

(I’m a little surprised that as many as 5 baby girls in Belgium got the English word “believe” as their first name. I wonder if something specific was influencing that usage…?)

This time around, Belgium also highlighted the girl and boy names that saw the largest increases and decreases in usage over the last decade (2011-2021). The top 5 in each category were…

  • Girl names
    • Largest increases: Alba, Ellie, Ellis, Alya, Cilou
    • Largest decreases: Lisa, Laura, Julie, Lotte, Anaïs
  • Boy names
    • Largest increases: Georges, Lio, Gaston, Otis, Lyam
    • Largest decreases: Maxime, Thomas, Simon, Wout, Nathan
