Where Kelly is most common

Compared with all babies born in each state since 1910, Kelly has been most common in Wyoming (1.6×), Delaware (1.5×), and Montana (1.5×), and least common in Mississippi (0.5×).

549,968 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.
