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

The counts come from Social Security card applications for babies born in the U.S., so the early years undercount everyone. A year with fewer than 5 babies of one sex given a name is left out for privacy and shows as fewer than 5. Spellings count separately: Emma and Ema are different names here.
