Where Kaitlyn is most common

Compared with all babies born in each state since 1910, Kaitlyn has been most common in Nevada (1.7×), Alaska (1.6×), and New Hampshire (1.5×), and least common in District of Columbia (0.19×).

165,861 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.
