Kou — boys' name

What the Data Says About Kou

The Social Security Administration has registered 691 babies named Kou between 1979 and 2017, spanning 39 consecutive years of U.S. birth records. As a boy's name, Kou currently falls outside the top 1,000 boys' names for 2017. The name reached its historical peak in 1992, when 48 babies received it in a single year.

Decade-level aggregation shows that Kou performed strongest in the 1980s, accumulating 323 births during that ten-year window. Across the 5 decades of recorded activity, Kou shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 257 births — the largest state-level total in the dataset — followed by Minnesota and Wisconsin. In total, SSA state-level files list Kou in 4 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Kou 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 691 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
