What the Data Says About Eustacia

As a girl's name, Eustacia currently falls outside the top 1,000 girls' names for 2000. The name reached its historical peak in 1971, when 15 babies received it in a single year.

Decade-level aggregation shows that Eustacia performed strongest in the 1970s, accumulating 67 births during that ten-year window. Across the 7 decades of recorded activity, Eustacia shows a clear decline from its mid-century high.

No etymological entry is currently available for Eustacia 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 156 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
