Thi — unisex name

What the Data Says About Thi

The Social Security Administration has registered 408 babies named Thi between 1976 and 2018, spanning 43 consecutive years of U.S. birth records. As a girl's name, Thi currently falls outside the top 1,000 girls' names for 2018. The name reached its historical peak in 1982, when 20 babies received it in a single year. Thi is classified as unisex in SSA records: the opposite-sex variant accounts for 63 additional births since 1979.

Decade-level aggregation shows that Thi performed strongest in the 1990s, accumulating 119 births during that ten-year window. Across the 5 decades of recorded activity, Thi shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 44 births — the largest state-level total in the dataset — followed by Texas. In total, SSA state-level files list Thi in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Thi 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 408 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
