Where Katelynn is most common

Compared with all babies born in each state since 1910, Katelynn has been most common in Nevada (1.9×), Utah (1.9×), and Oregon (1.8×), and least common in Hawaii (0.41×).

29,312 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.
