Origin
Meaning and origin of Costantino
The surname Costantino originated in Italy, specifically in the regions of Campania, Calabria, and Sicily. It is derived from the personal name Costantino, which ultimately traces its roots back to the Latin name Constantinus, meaning "constant" or "steadfast."
The name Costantino first appeared in historical records as early as the 11th century, with mentions of individuals bearing this surname in various medieval documents from southern Italy. One notable early reference is found in the Codex Diplomaticus Cavensis, a collection of medieval charters and documents from the Abbey of Cava in Campania, which includes records of individuals with the surname Costantino dating back to the 12th century.
In the 13th century, the surname Costantino can be found in the Angevin registers, which were administrative records kept by the Angevin dynasty that ruled the Kingdom of Naples and Sicily during that period. These records document individuals with the surname Costantino residing in various towns and villages throughout the southern Italian regions.
One of the earliest recorded individuals with the surname Costantino was Riccardo Costantino, a nobleman from the town of Amalfi in Campania, who lived in the late 12th century. Another notable figure was Matteo Costantino, a prominent jurist and legal scholar from Messina in Sicily, who lived in the 14th century.
In the 15th century, the surname Costantino appeared in the historical records of the Kingdom of Naples, with mentions of individuals such as Giovanni Costantino, a merchant from the city of Gaeta, and Tommaso Costantino, a landowner from the town of Avellino.
Over the centuries, several distinguished individuals have borne the surname Costantino. These include:
1. Antonio Costantino (1593-1662), an Italian painter and architect from Naples.
2. Francescantonio Costantino (1719-1786), an Italian jurist and writer from Capua.
3. Giuseppe Costantino (1845-1923), an Italian politician and journalist from Catania, Sicily.
4. Francesco Saverio Costantino (1848-1914), an Italian writer and philosopher from Naples.
5. Vincenzo Costantino (1869-1953), an Italian Catholic prelate who served as the Archbishop of Capua.
The surname Costantino has also been associated with various place names and older spellings of place names throughout southern Italy, such as Costantini (a comune in the province of Avellino), Costantinopoli (an ancient name for the city of Naples), and Costantinopoli di Calabria (an old name for the town of Palmi in Calabria).

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 Costantino 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 Costantino (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.
