Where Isidro is most common

Compared with all babies born in each state since 1910, Isidro has been most common in New Mexico (7.5×), Texas (6.2×), and California (3.5×), and least common in New York (0.18×).

6,101 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.
