Origin
The surname "CHIOLA" is of Italian origin, originating in the southern regions of the country, particularly in the regions of Campania and Calabria. It is believed to have derived from the Italian word "chiola," which means "a small creek" or "a small stream." This suggests that the name may have initially referred to someone who lived near a small waterway or a creek.
The earliest known record of the surname "CHIOLA" dates back to the 16th century. It is documented in various historical records and manuscripts from that period, including local church records and municipal documents. One notable reference can be found in the "Archivio di Stato di Napoli" (State Archive of Naples), which mentions a family bearing the surname "CHIOLA" residing in the town of Caserta during the late 1500s.
During the 17th and 18th centuries, the surname "CHIOLA" gained prominence in various parts of southern Italy. In the town of Salerno, records from the 1600s show the presence of a notable family named "CHIOLA," who were involved in local politics and trade. Another notable figure from this period was Antonio Chiola (1650-1718), a renowned sculptor and artist from the city of Naples.
In the 19th century, the surname "CHIOLA" spread across Italy and beyond, as members of the family migrated to other regions and countries. One notable individual from this period was Giuseppe Chiola (1822-1898), a prominent Italian lawyer and politician who served as a member of the Italian Parliament.
Another significant figure with the surname "CHIOLA" was Mario Chiola (1885-1961), an Italian philosopher and educator who made significant contributions to the field of education and pedagogy. He was born in the town of Potenza and later became a professor at the University of Naples.
Throughout history, there have been various place names and older spellings associated with the surname "CHIOLA." For instance, in the town of Caserta, there is a small hamlet known as "Chiola," which likely derived its name from the same root as the surname. Additionally, in some historical documents, the surname has been spelled as "Chiola," "Chiolla," or "Chiuola," reflecting regional variations in spelling and pronunciation.
Demographics
Among Census respondents with the surname Chiola, the largest self-reported group is White at 93.3%. The next largest groups are Two or More Races (3.3%) and Hispanic (2.5%).
The bar chart below shows how Chiola 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 Chiola 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.
