Where Kiley is most common
Compared with all babies born in each state since 1910, Kiley has been most common in Nebraska (2.3×), Utah (2×), and Iowa (1.6×), and least common in New York (0.43×).
16,854 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.
