Where Mary is most common

Compared with all babies born in each state since 1910, Mary has been most common in Mississippi (1.8×), Alabama (1.7×), and West Virginia (1.7×), and least common in Nevada (0.27×).

3,766,551 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.
