Where Kailey is most common

Compared with all babies born in each state since 1910, Kailey has been most common in Nevada (2×), Arizona (1.8×), and Florida (1.7×), and least common in North Dakota (0.34×).

25,680 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.
