What the Data Says About Challis

The Social Security Administration has registered 97 babies named Challis between 1945 and 2002, spanning 58 consecutive years of U.S. birth records. As a girl's name, Challis currently falls outside the top 1,000 girls' names for 2002. The name reached its historical peak in 1945, when 10 babies received it in a single year. Challis is classified as unisex in SSA records: the opposite-sex variant accounts for 31 additional births since 1914.

Decade-level aggregation shows that Challis performed strongest in the 1990s, accumulating 46 births during that ten-year window. Across the 6 decades of recorded activity, Challis shows a clear decline from its mid-century high.

No etymological entry is currently available for Challis 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 97 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
