Origin
The surname Ciummo is of Italian origin, likely originating from the southern regions of the country during the medieval period. It is believed to have derived from the Italian word "ciummo," which means "bundle" or "sheaf," suggesting that the name may have been an occupational surname for someone who worked with bundles of crops or materials.
One of the earliest recorded instances of the name Ciummo can be found in the historic records of the town of Nola, near Naples, dating back to the 14th century. These records mention a family named Ciummo residing in the area during that time. The name was also present in other parts of the Campania region, such as Salerno and Avellino, where variations like Ciummi and Ciummolo were more common.
In the 16th century, the name appears in the records of the town of Montella, in the province of Avellino, where a prominent figure named Pietro Ciummo is mentioned as a landowner and influential member of the community. This suggests that the Ciummo family had established a certain level of prominence in the region by that time.
Another notable individual bearing the surname Ciummo was Gaetano Ciummo, born in Naples in 1767. He was a renowned painter and engraver who studied under the guidance of famous artists such as Giacinto Diano and Fedele Fischetti. Gaetano Ciummo's works were highly regarded and can be found in various museums and galleries throughout Italy.
In the 19th century, a famous poet and writer named Raffaele Ciummo was born in Montella in 1840. He is known for his contributions to the Neapolitan dialect literature and his works that captured the essence of the local culture and traditions of the region.
Another notable figure was Giuseppe Ciummo, a military officer who served in the Italian army during World War I. Born in Salerno in 1888, he received several honors and decorations for his bravery and leadership on the battlefield.
It is also worth mentioning that variations of the surname, such as Ciummi and Ciummolo, were present in other regions of Italy, including Lazio and Puglia, suggesting that the name may have spread and evolved over time.
Demographics
Among Census respondents with the surname Ciummo, the largest self-reported group is White at 99.0%. The next largest groups are Two or More Races (1.0%).
The bar chart below shows how Ciummo 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 Ciummo 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.
