Where Sidney is most common

Compared with all babies born in each state since 1910, Sidney has been most common in Louisiana (3.1×), Mississippi (2.4×), and Alabama (1.7×), and least common in New Hampshire (0.24×).

93,813 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.
