Across the 8 decades of recorded activity, Lonza shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Alabama, which accounts for 5 births — the largest state-level total in the dataset — followed by Louisiana. In total, SSA state-level files list Lonza in 2 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Lonza 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 360 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
