Tokio — boys' name

What the Data Says About Tokio

The Social Security Administration has registered 55 babies named Tokio between 1913 and 1923, spanning 11 consecutive years of U.S. birth records. As a boy's name, Tokio currently falls outside the top 1,000 boys' names for 1923. The name reached its historical peak in 1920, when 9 babies received it in a single year.

Decade-level aggregation shows that Tokio performed strongest in the 1910s, accumulating 31 births during that ten-year window. Across the 2 decades of recorded activity, Tokio shows a stable profile with only moderate drift from its peak decade. Geographically, the name is most concentrated in Hawaii, which accounts for 16 births — the largest state-level total in the dataset — followed by California. In total, SSA state-level files list Tokio in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Tokio 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 55 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
