Recorded 1881–2007 · United States
Theresia was most popular in 1959, when 58 American babies were given the name — ranking #2,315 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 2,016 people named Theresia.
Across the whole record Theresia is a girl’s name — 100.0% of the 2,016 Americans given it were girls and 0.0% were boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
