Where Sydni is most common

Compared with all babies born in each state since 1910, Sydni has been most common in Louisiana (3.4×), Utah (2.7×), and Georgia (2.2×), and least common in New York (0.27×).

3,576 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.
