Kobe was 2020’s largest absolute increase by a good margin. (The second name on that list, Theodore, broke into the top 10 in 2021.)

Here are the boy names that saw the steepest dives out of the data (i.e., to below 5 instances of usage) in 2021:

  • given to 26 babies in 2020: Burhanuddin
  • given to 20 babies in 2020: Bader
  • given to 18 babies in 2020: Hyatt, Reylan
  • given to 17 babies in 2020: Abdelrahman
  • given to 16 babies in 2020: Kymeir

Interestingly, Dessa has dropped before — it was the fastest-falling girl name way back in 1933.

And I don’t think anyone will be surprised about the ongoing decline of Alexa.

Finally, here are the girl names that saw the steepest dives right out of the data (i.e., to below 5 instances of usage) in 2021:

  • given to 20 babies in 2020: Geisha
  • given to 17 babies in 2020: Glorianna, Malai, Taleigha

Boy names that debuted in the U.S. baby name data in 2021

lotus bud

Which boy names emerged in the U.S. baby name data in 2021 for the first time ever?

Exactly 500 boy names debuted in the data last year, and the most impressive debut was made by Azaire. Here are the other top debuts:

  1. Azaire, 25 baby boys
  2. Gediz, 21
  3. Jeyvier, 15
  4. Damiri, 14
  5. Ripton, 14
  6. Zakius, 13
  7. Kampbell, 12
  8. Biden, 11
  9. Khaizer, 11
  10. Nuta, 11
  11. Shrithik, 11

The name Biden was no doubt inspired by Joe Biden, who was elected president in late 2020.

Some more debuts:

10 baby boysAmaias, Azekial, Howl, Maclen, Oceano, Oleander
9 baby boysAathiran, Atlus, Avyaanreddy, Cymere, Dhamir, Eleo, Ice, Kapree, Kenshi, Kyza, Riftyn, Three, Yankiel
8 baby boysAadrik, Ador, Amirii, Anansi, Aurum, Ayaat, Bucklee, Emerett, Gervonta, Henlee, Hiyaan, Hyndrix, Inzo, Jerzi, Jetzyn, Jhayco, Karlisle, Kyngdom, Ledgend, Maaran, Ovi, Ovin, Rhiatt, Rodas, Sicarii, Svar, Wilden, Yahnis, Yasuke, Yzael, Zeldris

Finally, here’s a sampling of the rest of the debuts:

  • 7 baby boys: Arcturus, Arminius, Brixson, Darlington, Finnin, Habibullah, Jahvani, Kovie, Lobo, Mellow, Neptune, Osaro, Riften, Ropyr, Teghbir, Zagreus
  • 6 baby boys: Anwyll, Cardinal, Debonair, Evansh, Five, Gilber, Huxtin, Jovial, Kalki, Khrome, Koufax, Lightning, Lugh, Minhaj, Niqo, Pure, Rhema, Rizvan, Saturn, Torbjorn, Varenya, Whiskey, Ymir, Zeelan
  • 5 baby boys: Amnon, Benelli, Caique, Costner, Dhev, Endymion, Grit, Haaland, Henzo, Hotchner, Iyah, Jheico, Kazarion, Keeper, Laiku, Maestro, Nyne, Ohtli, Preacher, Quban, Regulus, Sango, Sansar, Science, Tancredi, Wickham, Woodensley, Yester, Yoshiyahu

Zagreus is the main character of the recently released video game Hades.

Haaland goes hand-in-hand with the fast-rising boy name Erling, as they both refer to Norwegian soccer player Erling Haaland (which alex has already noted — thank you!).

I think it’s particularly interesting that several number-names — Three (9), Five (6), and Nyne (5) — popped up last year. I have no idea why, though.

If you can explain any of the above debuts, please leave a comment!
