Joules is classified as unisex in SSA records: the opposite-sex variant accounts for 11 additional births since 2019.

Decade-level aggregation shows that Joules performed strongest in the 2010s, accumulating 30 births during that ten-year window. Across the 2 decades of recorded activity, Joules shows a clear decline from its mid-century high.

No etymological entry is currently available for Joules 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 37 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
