Where Ilyssa is more common than its national share predicts
Relative to its national share, Ilyssa is most over-represented in New York: since 1965 it was given 1.9 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Ilyssa with the births its national share predicts year by year, for states with at least 100 births of the name.
