Where Kelby is most common

Compared with all babies born in each state since 1910, Kelby has been most common in Utah (7.1×), Oklahoma (6.8×), and Texas (4.4×), and least common in California (0.34×).

1,603 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.
