    Only in Illinois

    The most common names that appear only in Illinois in 2025.

    What “only in Illinois” means: a name counts if it was given at least 5 times in Illinois in 2025 and fewer than 5 times in any other state (the 50 states and DC). SSA does not publish names given fewer than 5 times, so a name could exist elsewhere in smaller numbers. A full unique-names page for Illinois comes in a later batch.
