Uno — boys' name

What the Data Says About Uno

The Social Security Administration has registered 103 babies named Uno between 1908 and 1923, spanning 16 consecutive years of U.S. birth records. As a boy's name, Uno currently falls outside the top 1,000 boys' names for 1923. The name reached its historical peak in 1918, when 15 babies received it in a single year.

Decade-level aggregation shows that Uno performed strongest in the 1910s, accumulating 91 births during that ten-year window. Across the 3 decades of recorded activity, Uno shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Michigan, which accounts for 11 births — the largest state-level total in the dataset — followed by Minnesota. In total, SSA state-level files list Uno in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Uno 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 103 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
