Where Jillian is most common

Compared with all babies born in each state since 1910, Jillian has been most common in New Hampshire (3.5×), Massachusetts (2.6×), and Rhode Island (2.4×), and least common in North Dakota (0.2×).

81,563 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.
