The most gender-neutral baby names in the U.S. in 2024

pink and blue cupcakes

In 2024, close to 2,700 names appeared in the U.S. baby name data both as girl names and as boy names.

Which of these names were the most gender-neutral overall?

To create a useful set of rankings, I focused on names given to at least 150 babies in total. I sorted these names by how evenly they were given to babies of both genders, and the following came out on top:

Female usageMale usage
1. Charlie50.3% (2,109 girls)49.7% (2,084 boys)
2. Arden49.5% (237 girls)50.5% (242 boys)
3. Justice50.6% (206 girls)49.4% (201 boys)
4. Akari50.7% (107 girls)49.3% (104 boys)
5. Kit50.8% (188 girls)49.2% (182 boys)
6. Huntley51.0% (102 girls)49.0% (98 boys)

24. Sidney46.1% (117 girls)53.9% (137 boys)
25. Chandler46.0% (297 girls)54.0% (348 boys)

More than half of the above appeared on the 2023 list as well.

None of last year’s fifty-fifty splits were popular enough to make the cut, but Lou — given to 70 girls and 70 boys — came close.

How interesting that Ambre, the second-most-popular girl name in France, just barely made the top 50 in Paris.

The girls’ top 100 included Raphaëlle (63rd), Olympe (76th), Brune (83rd), and Marie (99th).

The boys’ top 100 included Gustave (67th), Naël (78th), Malo (83rd), and Aurèle (96th).

Here’s a selection of names from lower down in the rankings, which includes all names given to at least five Parisian babies (of either one gender or the other) per year.

Girl namesBoy names
Castille (25 baby girls), Gisèle (19), Sibylle (17), Ninon (14), Ysé (12), Olympia (11), Alizée (6), Amicie (5), Domitille (5), Lital (5)Hippolyte (26 baby boys), Soan (26), Edouard (22), Zacharie (17), Mayeul (6), Armel (5), Doron (5), Manoé (5), Pacôme (5), Wandrille (5)

Wandrille is the French form of the Germanic name Wandregisel (which belonged to a 7th-century Catholic saint). The second element of Wandregisel is the same element upon which the name Gisèle is based.

Finally, here’s a link to Paris’ 2022 rankings, if you’d like to compare last year to the year before.

P.S. Do you think the Paris Olympics will inspire more French parents to choose the girl names Olympe and Olympia in 2024?
