Across the 3 decades of recorded activity, Sylwia shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Illinois, which accounts for 41 births — the largest state-level total in the dataset — followed by New York. In total, SSA state-level files list Sylwia in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Sylwia 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 119 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
