Origin
The surname DiCarlo is of Italian origin, derived from the region of Calabria in southern Italy. It dates back to the medieval period, around the 13th or 14th century. The name is a combination of the Italian preposition "di" meaning "of" or "from" and the place name "Carlo" which is derived from the Latinized form of the Germanic name "Charles" or "Karl."
One of the earliest recorded instances of the name DiCarlo can be found in the "Codice diplomatico Barese," a collection of medieval documents from the region of Bari, dating back to the 14th century. The name appears as "de Carlo" in these records, indicating its origins as a locative surname, denoting a person's place of origin or residence.
In the 16th century, the surname DiCarlo is mentioned in the "Libro delle Famiglie Nobili di Napoli" (Book of Noble Families of Naples), which recorded the noble families of the Kingdom of Naples. This suggests that the name was associated with nobility or gentry in that region during that time period.
One notable bearer of the surname was Giovanni DiCarlo, a 17th-century Italian composer and organist who was active in Naples and Rome. He was born in 1614 and died in 1684, leaving behind a significant body of sacred and secular music.
Another prominent figure with the surname DiCarlo was Pietro DiCarlo, an Italian soldier and military engineer who lived in the 18th century. He served in the armies of the Kingdom of Naples and was renowned for his expertise in fortifications and siege warfare.
In the 19th century, the name DiCarlo gained recognition through the works of the Italian playwright and author Vincenzo DiCarlo, who was born in 1836 in Palermo, Sicily. He wrote numerous plays and novels that explored themes of social justice and critiqued the societal norms of his time.
The surname DiCarlo has also been associated with various place names and localities in Italy, such as the town of Carlentini in the province of Syracuse, Sicily, which was formerly known as "Carlentino" or "Carlentu" in ancient times. These place names may have influenced the formation of the surname in certain regions.
Throughout its history, the surname DiCarlo has been subject to various spelling variations, including DeCarlo, DeCaroli, and Carlocci, among others. These variations reflect the regional dialects and linguistic influences that have shaped the name over centuries.
Demographics
Among Census respondents with the surname Dicarlo, the largest self-reported group is White at 91.6%. The next largest groups are Hispanic (4.9%) and Two or More Races (2.3%).
The bar chart below shows how Dicarlo 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 Dicarlo 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 Dicarlo (2000, 2010, 2020).
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.
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.
