Ontario — #10058 US boys' name

What the Data Says About Ontario

The Social Security Administration has registered 877 babies named Ontario between 1967 and 2024, spanning 58 consecutive years of U.S. birth records. As a boy's name, Ontario currently holds the #10058 rank among boys for 2024. The name reached its historical peak in 1991, when 35 babies received it in a single year.

Decade-level aggregation shows that Ontario performed strongest in the 1990s, accumulating 225 births during that ten-year window. Across the 7 decades of recorded activity, Ontario shows a clear decline from its mid-century high. Geographically, the name is most concentrated in Georgia, which accounts for 30 births — the largest state-level total in the dataset — followed by Mississippi and Louisiana. In total, SSA state-level files list Ontario in 5 of the 51 U.S. reporting jurisdictions.

No etymological entry is currently available for Ontario 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 877 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
