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:

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.
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.
In 2022, the Western European country of Luxembourg welcomed 6,495 babies — 49.2% of which were girls, 50.8% of which were boys.
Among the citizens of Luxembourg, the top baby names were Mia and Leo. (Tiny names for a tiny nation!)
Among the foreign nationals — who account for nearly half of the Grand Duchy’s population — the top baby names were Emma and Gabriel.
These were the top 5 girl names and top 5 boy names among Luxembourgers in 2022:
Girl names
Mia, 28 baby girls
Emma, 27
Eva, 20 (tie)
Lea, 20 (tie)
Olivia, 19
Boy names
Leo, 36 baby boys
Liam, 33 (tie)
Noah, 33 (tie)
Louis, 24 (tie)
Matteo, 24 (tie)
And these were the top 5 girl names and top 5 boy names among immigrants in 2022:
Girl names (immigrants)
Emma, 25 baby girls
Maria, 22
Sofia, 20
Alice, 18
Chloé, 17
Boy names (immigrants)
Gabriel, 27 baby boys
Lucas, 21
Alexander, 15 (tie)
David, 15 (tie)
Adam, 14
The vast majority of Luxembourg’s immigrants come from other EU countries, such as Portugal, Italy, France, and Belgium. (Luxembourg’s first baby of 2023, in fact, was born to a Belgian family. She was named Liv.)
In 2021, the top baby names (overall) in Luxembourg were Emma and Louis.
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

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.)

Many of these are used primarily by Spanish speakers.

Now, back to the names that both countries had in common. Of the boy names used more frequently in the U.S. than in Canada, the 10 below had the largest pro-U.S. differentials.
