Where Cain is most common

Compared with all babies born in each state since 1910, Cain has been most common in Arizona (2.9×), Louisiana (2.4×), and California (2.2×), and least common in New York (0.33×).

5,007 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.
