In total, SSA state-level files list Mary in 51 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Mary 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 4,139,160 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
