Is Lucilla a boy’s or a girl’s name?
Lucilla has been recorded only for girls: SSA lists no boys with the name in 91 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Lucilla: the SSA national file counts each sex separately.
How many people are named Lucilla, and how old are they?
An estimated 565 Americans named Lucilla and born in the U.S. are alive in 2026 (59% of everyone recorded); the median is 53 years old and half are between 12 and 71. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 893 people named Lucilla (892 women and girls, 1 man or boy). SSA’s births carried forward to Census day, April 1, 2020, predict 557 born in the U.S. The Census count is 1.6 times that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.
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).
