[OC] 50 US-amerikanische Namen mit hoher Konzentration innerhalb einer einzigen Generation

**Data source:** U.S. Social Security Administration (2024)

**Tools:** Python / SQL / Hex / Figma

Out of 1,087 names with over 50k lifetime births, I used a rolling 20-year window to find the maximum concentration of births for each name, calculated separately by gender. These 50 were selected from the 169 names that crossed the 75% threshold, prioritizing lifetime volume and names with exceptionally high spikes.

A few things to keep in mind:

* Just because a large share of births fell within the window doesn’t mean the name wasn’t also common outside it. For the most popular names, even <25% could be hundreds of thousands of babies.
* Many popular names were spread across longer periods and just missed the threshold, like Jennifer (23 years), Jason (23 years), or Susan (24 years).
* Newer names haven’t had as much time to spread across multiple generations, so it makes sense that their concentration scores would be higher. If Aiden becomes as timeless as Michael or James, it could fall off this list in a few decades.

Happy to pull stats on any specific names not on this list if you’re curious.

I think this is a really interesting question, but it also seems like „concentrated names“ are names with a tail, which leads to the most recent names being more concentrated than any previous.

Weird that so many would be named “Kathy”. It’s a nickname. No Katherines or Catherines or Kathryns, etc…..just Kathy. Odd.

Aiden appears twice. Does that mean the overlap between them is over 75%?

Lot of white poverty names post 1972
