What the Data Says About Thos

As a boy's name, Thos currently falls outside the top 1,000 boys' names for 1928. The name reached its historical peak in 1915, when 14 babies received it in a single year.

Decade-level aggregation shows that Thos performed strongest in the 1910s, accumulating 85 births during that ten-year window. Across the 5 decades of recorded activity, Thos shows a clear decline from its mid-century high.

No etymological entry is currently available for Thos 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 166 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
