Across the 3 decades of recorded activity, Isyss shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 45 births — the largest state-level total in the dataset — followed by New York and Texas. In total, SSA state-level files list Isyss in 11 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Isyss 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 594 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
