Origin
The surname Ruffalo is of Italian origin, deriving from the region of Campania in southern Italy. It is believed to have emerged in the 14th century as a variation of the Italian word "ruffo," meaning "reddish" or "reddish-brown." This suggests that the name may have initially been bestowed upon someone with reddish hair or a ruddy complexion.
The earliest recorded instances of the name Ruffalo can be traced back to the town of Nola, located near Naples in the Campania region. In medieval records from the 1300s, variations such as "Ruffalus" and "Rufalo" can be found, indicating the name's evolution over time.
One notable historical figure bearing the Ruffalo surname was Pietro Ruffalo, a prominent merchant and banker who lived in Naples during the late 15th century. His business dealings and wealth made him a influential figure in the city's economic affairs.
In the 16th century, the name Ruffalo appeared in several historical documents related to the Kingdom of Naples, including tax records and property deeds. This suggests that the name had gained some prominence among the local population during this period.
Another notable individual with the Ruffalo surname was Gianfranco Ruffalo, a renowned artist and sculptor who lived in the city of Salerno in the 17th century. His works, which included intricate sculptures and religious art, can still be found in various churches and museums throughout the region.
In the 18th century, the name Ruffalo was also found in records from the town of Avellino, located in the neighboring Campania region. One such individual was Antonio Ruffalo, a respected lawyer and legal scholar who authored several influential texts on local laws and customs.
As the Ruffalo name spread throughout Italy and beyond, it encountered variations in spelling and pronunciation. In some regions, it was recorded as "Rufalo" or "Ruffalo," while in others, it took on forms such as "Ruffoli" or "Ruffali."
Throughout its history, the Ruffalo surname has maintained a strong association with its Italian roots, particularly in the Campania region. While the name has since spread to other parts of the world, its origins can be traced back to the reddish-hued landscapes and vibrant cultural heritage of southern Italy.
Demographics
Among Census respondents with the surname Ruffalo, the largest self-reported group is White at 88.0%. The next largest groups are Hispanic (7.4%) and Two or More Races (4.0%).
The bar chart below shows how Ruffalo 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 Ruffalo 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.
