Origin
The surname Cirio is believed to have originated in Italy, specifically in the region of Piedmont. It is thought to have derived from the Italian word "ciro," which means "wax" or "candle." This suggests that the name may have been associated with an occupation or trade involving the production or sale of candles or wax-related products.
One of the earliest known references to the name Cirio can be found in historical records from the city of Turin, dating back to the 16th century. These records mention individuals with the surname Cirio engaged in various professions, including candlemakers, merchants, and artisans.
In the late 19th century, the Cirio family gained prominence in the food industry. Francesco Cirio (1824-1917), a native of Nizza Monferrato, established the Cirio Company, which became renowned for its canned tomatoes and other preserved foods. The company's products were exported worldwide, and the Cirio name became synonymous with quality and innovation in the food manufacturing sector.
Another notable individual with the surname Cirio was Ettore Cirio (1864-1942), an Italian businessman and politician. He served as a member of the Italian Parliament and played a significant role in the economic development of the Piedmont region during the early 20th century.
In the realm of arts and culture, the surname Cirio is associated with the Italian painter and sculptor Vincenzo Cirio (1828-1906). Born in Turin, Cirio's works were widely exhibited and celebrated during the Risorgimento period in Italy.
The name Cirio has also been documented in other parts of Europe, including France and Spain, likely due to migration and trade connections. For instance, the French artist Louis Cirio (1799-1880), born in Lyon, achieved recognition for his landscape and genre paintings during the 19th century.
While the surname Cirio has its roots in Italy, it has since spread to various parts of the world through immigration and diaspora. Individuals bearing this surname can be found in countries such as Argentina, Brazil, and the United States, where Italian communities have established themselves over the centuries.
Demographics
Among Census respondents with the surname Cirio, the largest self-reported group is White at 45.3%. The next largest groups are Hispanic (37.6%) and Asian/Pacific Islander (11.1%).
The bar chart below shows how Cirio 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 Cirio 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.
