What the Data Says About Lilliah

As a girl's name, Lilliah currently falls outside the top 1,000 girls' names for 2025. The name reached its historical peak in 2014, when 15 babies received it in a single year.

Decade-level aggregation shows that Lilliah performed strongest in the 2010s, accumulating 104 births during that ten-year window. Across the 4 decades of recorded activity, Lilliah shows a clear decline from its mid-century high.

No etymological entry is currently available for Lilliah 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 193 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
