Theresia — girls' name

What the Data Says About Theresia

The Social Security Administration has registered 2,016 babies named Theresia between 1881 and 2007, spanning 127 consecutive years of U.S. birth records. As a girl's name, Theresia currently falls outside the top 1,000 girls' names for 2007. The name reached its historical peak in 1959, when 58 babies received it in a single year.

Decade-level aggregation shows that Theresia performed strongest in the 1950s, accumulating 375 births during that ten-year window. Across the 13 decades of recorded activity, Theresia shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Texas, which accounts for 34 births — the largest state-level total in the dataset — followed by California and Georgia. In total, SSA state-level files list Theresia in 11 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Theresia in our reference dataset. These figures derive from SSA's annual national and state-level name files, which include any name appearing at least five times in a given year or state-year; names below that threshold are suppressed for privacy and therefore excluded from the totals shown here. The 2,016 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
