Popular baby names in Monaco, 2023

Flag of Monaco
Flag of Monaco

In 2023, the Western European microstate of Monaco welcomed 804 babies — 388 baby girls and 416 baby boys. All of these babies were born in Monaco’s single public hospital, the Centre Hospitalier Princesse Grace (which was named after Grace Kelly).

Notably, though, only 229 them were born to residents of Monaco. The other 575 were born to non-residents, most of whom came from the nearby French communes of Menton, Roquebrune-Cap-Martin, and Beausoleil.

So, what were the most popular names among the (mostly French) babies born in Monaco last year? Louise and Théo.

Here are Monaco’s top 5 girl names and top 5 boy names of 2023:

Girl names

  1. Louise
  2. Chloé
  3. Emma
  4. Jade
  5. Chiara

Boy names

  1. Théo
  2. Gabriel
  3. Léo
  4. Leonardo
  5. Andrea

Last year’s newborns included “the latest member of the Grimaldi family” — a baby girl named Victoire, born in April to Louis Ducruet (the son of Princess Stéphanie, whose brother, Prince Albert, is the current head of state). The House of Grimaldi has been the reigning house of the Principality of Monaco since the late 13th century.

In 2022, the top names in Monaco were Emma and Leonardo.

Where did the baby name Cavett come from in 1973?

Talk show host Dick Cavett (in 1971)
Dick Cavett

The surname Cavett made its first and only appearance in the U.S. baby name data in the early 1970s:

  • 1975: unlisted
  • 1974: unlisted
  • 1973: 5 baby boys named Cavett [debut]
  • 1972: unlisted
  • 1971: unlisted

What put it there?

My guess is Dick Cavett, host of The Dick Cavett Show.

Different versions of Cavett’s Emmy-winning talk show were broadcast on television from the late ’60s to the early 2000s, but the most popular incarnation aired late-night on ABC — opposite Johnny Carson’s Tonight Show on NBC — from 1969 to 1974.

What differentiated Cavett from Carson? Cavett had a more intellectual approach to comedy, and also interviewed a wider range of guests — not just movie stars and musicians, but also filmmakers, athletes, authors, journalists, politicians, activists, scientists, artists, and so forth. Cavett’s guests included Alfred Hitchcock, Arthur C. Clarke, Bobby Fischer, Christiaan Barnard, Harland Sanders, Hugh Hefner, Jackie Robinson, Jacques Cousteau, Janis Joplin, Jimi Hendrix, John Lennon (and Yoko Ono), Louis Armstrong, Muhammad Ali, Orson Welles, and Salvador Dalí.

Cavett’s Scottish surname was derived from a similar French surname, Cavet, which originally referred to either someone who worked with a cavet (a type of hoe) or someone who lived near or in a cave.

What are your thoughts on Cavett as a first name?

In 2021, the top baby names (overall) in Luxembourg were Emma and Louis.

Which boy names are the most Canadian?

Maligne Lake, Canada

Yesterday we came up with some girl names that were either particularly Canadian or particularly American. So today let’s do the same thing for boy names.

Again, here are the two different methods:

First, we’ll look at the most popular names that appeared in only one set of data (either Canada or the U.S.) in 2022.

Second, we’ll look at the names that appeared in both sets of data, focusing on how proportionally popular each name was in each place. For the boy names below, I calculated the proportions by dividing each name’s U.S. usage by the total number of boys born in the U.S. last year (1,863,582) and each name’s Canadian usage by the total number of boys born Canada last year (180,763).

Top Canada-only boy names

The 2022 Canadian data included 261 boy names that were not in the U.S. data. Below are the 10 most popular Canada-only boy names.

Number of boys (Can.)Rank (Can.)
1. Edouard49249th
2. Arnaud35285th
3. Florent73394th

8. Gregoire30831st
9. Charles-Edouard27 (tie)902nd (tie)
10. Gurniwaz27 (tie)902nd (tie)

Nine out of ten are French names used primarily in Quebec:

  • Edouard: 482 of 492 born in Quebec
  • Arnaud: 349 of 352
  • Florent: 71 of 73
  • Laurier: 60 of 60 (all)
  • Loik: 47 of 57
  • Ludovick: 45 of 45 (all)
  • Renaud: 40 of 42
  • Gregoire: 30 of 30 (all)
  • Charles-Edouard: 25 of 27

The Sikh name Gurniwaz, however, was not used in Quebec at all.

Boy names particularly popular in Canada

Now let’s look at the more than 2,950 boy names that appeared in both sets of data. Of the boy names used more frequently in Canada than in the U.S., the 10 below had the largest pro-Canada differentials. (I added the rankings for both countries as well.)
