Where Sean is most common

Compared with all babies born in each state since 1910, Sean has been most common in Alaska (2.1×), Hawaii (2×), and Delaware (1.9×), and least common in Mississippi (0.32×).

423,275 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.
