Sofia: U.S. name history
Published Social Security birth-name counts for the exact spelling Sofia in the female recorded field, 1880–2025.
In the latest file, Sofia was at position 9 among published female-field spellings, with 8,252 recorded births. That is up 139 from 8,113 in 2024. Its first released row in this archive is from 1881; a missing earlier row does not establish when the name began to exist.
What the historical pattern shows
Sofia and Sophia are separate spellings in the SSA files. Sofia was position 161 in 2000, reached position 14 in 2015, and entered the top ten by 2024. The 2025 file placed it ninth.
Sofia's highest annual count in this archive was in 2015. It is tempting to explain the difference from Sophia through language or heritage, but these aggregate records do not establish the background of any family that chose either spelling.
