Moo — boys' name

What the Data Says About Moo

The Social Security Administration has registered 72 babies named Moo between 2010 and 2023, spanning 14 consecutive years of U.S. birth records. As a boy's name, Moo currently falls outside the top 1,000 boys' names for 2023. The name reached its historical peak in 2013, when 11 babies received it in a single year. Moo is classified as unisex in SSA records: the opposite-sex variant accounts for 49 additional births since 2008.

Decade-level aggregation shows that Moo performed strongest in the 2010s, accumulating 61 births during that ten-year window. Across the 2 decades of recorded activity, Moo shows a clear decline from its mid-century high.

No etymological entry is currently available for Moo 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 72 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
