Mc — boys' name

What the Data Says About Mc

The Social Security Administration has registered 227 babies named Mc between 1912 and 1999, spanning 88 consecutive years of U.S. birth records. As a boy's name, Mc currently falls outside the top 1,000 boys' names for 1999. The name reached its historical peak in 1939, when 13 babies received it in a single year. Mc is classified as unisex in SSA records: the opposite-sex variant accounts for 209 additional births since 1989.

Decade-level aggregation shows that Mc performed strongest in the 1990s, accumulating 61 births during that ten-year window. Across the 5 decades of recorded activity, Mc shows a stable profile with only moderate drift from its peak decade.

No etymological entry is currently available for Mc 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 227 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
