Where Lenny is most common

Compared with all babies born in each state since 1910, Lenny has been most common in New York (3.9×), California (2.2×), and New Jersey (2.1×), and least common in Indiana (0.39×).

4,693 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.
