Thu — girls' name

What the Data Says About Thu

The Social Security Administration has registered 832 babies named Thu between 1975 and 2018, spanning 44 consecutive years of U.S. birth records. As a girl's name, Thu currently falls outside the top 1,000 girls' names for 2018. The name reached its historical peak in 1983, when 55 babies received it in a single year.

Decade-level aggregation shows that Thu performed strongest in the 1980s, accumulating 378 births during that ten-year window. Across the 5 decades of recorded activity, Thu shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 169 births — the largest state-level total in the dataset — followed by Texas and Louisiana. In total, SSA state-level files list Thu in 3 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Thu 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 832 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
