U.S. Social Security Administration, Baby Names from Social Security Card Applications (state data) (Public domain (U.S. government work)), data for 2025.

The counts come from Social Security card applications for babies born in Illinois. Names given to fewer than 5 babies of one sex in the state in a year are left out for privacy. Names with the same number of babies share a rank, and spellings count separately: Sofia and Sophia are different names here.
