Ka — unisex name

What the Data Says About Ka

The Social Security Administration has registered 781 babies named Ka between 1962 and 2004, spanning 43 consecutive years of U.S. birth records. As a girl's name, Ka currently falls outside the top 1,000 girls' names for 2004. The name reached its historical peak in 1990, when 65 babies received it in a single year. Ka is classified as unisex in SSA records: the opposite-sex variant accounts for 136 additional births since 1976.

Decade-level aggregation shows that Ka performed strongest in the 1990s, accumulating 375 births during that ten-year window. Across the 5 decades of recorded activity, Ka shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 241 births — the largest state-level total in the dataset — followed by Minnesota and Wisconsin. In total, SSA state-level files list Ka in 3 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Ka 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 781 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
