About 1 boy in 41,660 born in 2025 was given one of these spellings — against 1 in 284,679 for Ja itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

What happens to a name after it peaks
The Moritz test
Every popular name lives one long story — a climb, a peak, a slow settling back. Ja's later chapters haven't been written yet, so we borrowed them: Moritz climbed just as high around 1946, and its whole arc is on record. Line the two peaks up, and Moritz's path sketches the road Ja is walking now.
Ja sits in the calm middle of the cycle — neither chasing a wave nor sliding off one. Middle-of-the-cycle names age slowly and predictably.
