Decade-level aggregation shows that Thersa performed strongest in the 1960s, accumulating 326 births during that ten-year window. Across the 11 decades of recorded activity, Thersa shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 10 births — the largest state-level total in the dataset — followed by South Carolina and Texas. In total, SSA state-level files list Thersa in 5 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Thersa 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 1,071 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
