Lo — unisex name

What the Data Says About Lo

The Social Security Administration has registered 53 babies named Lo between 1920 and 2023, spanning 104 consecutive years of U.S. birth records. As a girl's name, Lo currently falls outside the top 1,000 girls' names for 2023. The name reached its historical peak in 1935, when 6 babies received it in a single year. Lo is classified as unisex in SSA records: the opposite-sex variant accounts for 33 additional births since 1982.

Decade-level aggregation shows that Lo performed strongest in the 2020s, accumulating 21 births during that ten-year window. Across the 5 decades of recorded activity, Lo shows a stable profile with only moderate drift from its peak decade.

No etymological entry is currently available for Lo 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 53 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
