Where Sebastian is most common

Compared with all babies born in each state since 1910, Sebastian has been most common in Nevada (3.8×), Arizona (2.7×), and Florida (2.5×), and least common in West Virginia (0.17×).

215,007 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.
