Where Isiah is most common
Compared with all babies born in each state since 1910, Isiah has been most common in South Carolina (4.1×), Mississippi (3.1×), and New Mexico (3×), and least common in Iowa (0.19×).
20,277 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.
