Where Cydney is most common

Compared with all babies born in each state since 1910, Cydney has been most common in Georgia (2.3×), Texas (1.9×), and California (1.8×), and least common in New York (0.73×).

2,471 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.
