Katheleen — girls' name

What the Data Says About Katheleen

The Social Security Administration has registered 1,230 babies named Katheleen between 1909 and 2008, spanning 100 consecutive years of U.S. birth records. As a girl's name, Katheleen currently falls outside the top 1,000 girls' names for 2008. The name reached its historical peak in 1952, when 33 babies received it in a single year.

Decade-level aggregation shows that Katheleen performed strongest in the 1950s, accumulating 267 births during that ten-year window. Across the 11 decades of recorded activity, Katheleen shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 16 births — the largest state-level total in the dataset — followed by Illinois and New York. In total, SSA state-level files list Katheleen in 3 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Katheleen 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 1,230 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
