Origin
The surname CAOLA has its origins in northern Italy, dating back to the medieval period around the 11th century. It is believed to have derived from the Latin word "caulis," meaning cabbage or stalk, indicating that the name may have been associated with those who cultivated or traded in these crops.
One of the earliest recorded instances of the name CAOLA can be found in the Codice Diplomatico Longobardo, a collection of historical documents from the Lombard period in Italy, which mentions a certain "Petrus de Caola" in the year 1146. This suggests that the name was already established in the region by that time.
During the 13th century, the CAOLA name appears in various records from the city of Verona, which was a prominent center of trade and commerce in northern Italy. For instance, a certain "Guglielmo CAOLA" is mentioned in a document from 1278, indicating his involvement in the local mercantile activities.
In the 14th century, the name CAOLA gained prominence in the town of Sanguinetto, near Verona. Historical records from this period mention several individuals with this surname, including "Giacomo CAOLA," who was a respected landowner and local official in the year 1352.
One of the earliest known bearers of the CAOLA name was Bartolomeo CAOLA, a renowned painter and fresco artist who lived in the 15th century. Born in Verona around 1420, he is credited with creating numerous works of art that adorned churches and buildings throughout northern Italy.
Another notable figure was Giovanni CAOLA, a scholar and theologian who lived in the 16th century. Born in Sanguinetto in 1522, he studied at the University of Padua and later became a professor of theology at the University of Bologna, where he taught for many years until his death in 1591.
The CAOLA name also has connections to the world of literature. In the 17th century, a poet named Antonio CAOLA gained recognition for his works, including a collection of sonnets published in 1649. He was born in Verona in 1612 and is believed to have been part of a literary circle in that city.
During the 18th century, the CAOLA surname spread beyond northern Italy, with some branches of the family settling in other regions of the country. One notable example is Francesco CAOLA, a military officer born in Naples in 1734, who served in the army of the Kingdom of Naples and distinguished himself in various campaigns.
Throughout the centuries, the CAOLA name has maintained a strong presence in northern Italy, particularly in the regions of Veneto and Lombardy. While the spelling may have undergone minor variations over time, the core of the name has remained intact, reflecting its deep-rooted historical and cultural significance.
Demographics
Among Census respondents with the surname Caola, the largest self-reported group is White at 91.1%. The next largest groups are Hispanic (3.6%) and Asian/Pacific Islander (2.7%).
The bar chart below shows how Caola 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 Caola surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
