Hideo — boys' name

What the Data Says About Hideo

The Social Security Administration has registered 805 babies named Hideo between 1910 and 1944, spanning 35 consecutive years of U.S. birth records. As a boy's name, Hideo currently falls outside the top 1,000 boys' names for 1944. The name reached its historical peak in 1925, when 62 babies received it in a single year.

Decade-level aggregation shows that Hideo performed strongest in the 1920s, accumulating 426 births during that ten-year window. Across the 4 decades of recorded activity, Hideo shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Hawaii, which accounts for 380 births — the largest state-level total in the dataset — followed by California and Washington. In total, SSA state-level files list Hideo in 3 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Hideo 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 805 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
