Is Lucius a boy’s or a girl’s name?
Lucius has been recorded only for boys: SSA lists no girls with the name in 146 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Lucius: the SSA national file counts each sex separately.
How many people are named Lucius, and how old are they?
5,380 alive in 2026, estimated
That is 53% of the 10,108 Americans ever recorded as Lucius. The median Lucius alive today is 20 years old; half are between 10 and 56.
The 2020 Census counted 4,036 people named Lucius (14 women and girls, 4,022 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 4,899 born in the U.S. The Census count is 18% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).

Where Lucius is more common than its national share predicts
Relative to its national share, Lucius is most over-represented in South Carolina: since 1910 it was given 4.0 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Lucius with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
