Origin
Meaning and origin of Lucio
The surname Lucio has its roots in Italy, tracing back to the late medieval period. It is derived from the Latin name Lucius, which means "bright" or "shining." This name was particularly popular in ancient Rome and was borne by several notable historical figures.
One of the earliest recorded instances of the surname Lucio can be found in the Codex Diplomaticus Cavensis, a collection of medieval charters from the Campania region of southern Italy, dating back to the 11th century. The name appears in various forms, such as Lucius, Lucio, and Luccio, suggesting its widespread usage in the area.
During the Renaissance period, the name Lucio gained prominence in Italian literature and art. One notable bearer of the name was Lucio Battisti (1935-1998), an Italian singer-songwriter and composer who was a prominent figure in the Italian pop music scene of the 1960s and 1970s.
In the 16th century, the surname Lucio can be found in historical records from the city of Naples. Antonio Lucio (c. 1505-1583) was a renowned Neapolitan philosopher and jurist who played an influential role in the development of legal thought during the Renaissance.
Moving further back in time, the name Lucio has been associated with several Roman emperors. One of the most notable was Lucius Verus (130-169 AD), who co-ruled the Roman Empire alongside Marcus Aurelius from 161 to 169 AD.
Another historical figure bearing the surname Lucio was Lucio Vitruvio Pollione (c. 80-70 BC), a Roman architect, engineer, and author of the influential treatise "De Architectura," which was a significant contribution to the field of architecture in ancient Rome.
In the realm of literature, Lucio Anneo Seneca (c. 4 BC-65 AD), a Roman Stoic philosopher, dramatist, and statesman, was a prominent figure in the Silver Age of Latin literature. His writings, including his philosophical works and tragedies, had a lasting impact on Western thought and literature.
While the surname Lucio has its origins in Italy, it has since spread to other parts of the world, particularly Latin American countries, where it is often spelled as Lucío or Luzio. However, the historical roots and significance of this name remain firmly grounded in the rich cultural heritage of Italy.

The bar chart below shows how Lucio bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Lucio surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lucio (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
