Where Allen is most common

Compared with all babies born in each state since 1910, Allen has been most common in North Dakota (2×), South Dakota (1.8×), and Louisiana (1.7×), and least common in Arizona (0.63×).

263,712 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.
