Eureka — girls' name

What the Data Says About Eureka

The Social Security Administration has registered 855 babies named Eureka between 1913 and 2022, spanning 110 consecutive years of U.S. birth records. As a girl's name, Eureka currently falls outside the top 1,000 girls' names for 2022. The name reached its historical peak in 1974, when 43 babies received it in a single year.

Decade-level aggregation shows that Eureka performed strongest in the 1970s, accumulating 375 births during that ten-year window. Across the 9 decades of recorded activity, Eureka shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Louisiana, which accounts for 34 births — the largest state-level total in the dataset — followed by Georgia and Texas. In total, SSA state-level files list Eureka in 7 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Eureka 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 855 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
