Where Kailyn is most common

Compared with all babies born in each state since 1910, Kailyn has been most common in Florida (1.9×), Louisiana (1.9×), and Georgia (1.8×), and least common in Oregon (0.28×).

12,449 births recorded by state, 1910–2025. 2× means twice as common as nationally. States with fewer than 30 such births are left blank, and SSA withholds any year with fewer than 5 in a state, so small states read low.
