counting every spelling

The SSA counts spellings, not names. Kaido went to 32 boys in 2025, but Kaydo is the same name said out loud. Together the 2 spellings went to 38, which makes it the 890th most-given boys’ name of the year — 2,623 places above the chart.

About 1 boy in 44,949 born in 2025 was given one of these spellings — against 1 in 53,377 for Kaido 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

Line the two peaks up, and Keyontae's path sketches the road Kaido is walking now.
