Pat — unisex name

What the Data Says About Pat

The Social Security Administration has registered 40,122 babies named Pat between 1897 and 1991, spanning 95 consecutive years of U.S. birth records. As a girl's name, Pat currently falls outside the top 1,000 girls' names for 1991. The name reached its historical peak in 1941, when 1,900 babies received it in a single year. Pat is classified as unisex in SSA records: the opposite-sex variant accounts for 26,732 additional births since 1880.

Decade-level aggregation shows that Pat performed strongest in the 1940s, accumulating 16,150 births during that ten-year window. Across the 11 decades of recorded activity, Pat shows a clear decline from its mid-century high. Geographically, the name is most concentrated in California, which accounts for 5,015 births — the largest state-level total in the dataset — followed by Illinois and Texas. In total, SSA state-level files list Pat in 47 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Pat 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 40,122 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
