Is Leoncio a boy’s or a girl’s name?
Leoncio has been recorded only for boys: SSA lists no girls with the name in 59 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Leoncio: the SSA national file counts each sex separately.
How many people are named Leoncio, and how old are they?
An estimated 492 Americans named Leoncio and born in the U.S. are alive in 2026 (94% of everyone recorded); the median is 30 years old and half are between 18 and 43. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 2,162 people named Leoncio (1 woman or girl, 2,161 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 455 born in the U.S. The Census count is 4.8 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).
