Origin
The surname MASCOLO is of Italian origin, tracing its roots back to the southern regions of Italy, particularly in the regions of Campania and Basilicata. It is believed to have emerged during the Middle Ages, likely between the 11th and 13th centuries.
The name MASCOLO is derived from the Italian word "mascolo," which means "male" or "masculine." This suggests that the name may have been initially used as a descriptive nickname or a reference to a person's physical characteristics or demeanor.
While there are no definitive records of the name appearing in early medieval manuscripts or chronicles, its presence can be found in various historical documents from the 14th century onwards. For instance, the name MASCOLO is mentioned in records from the town of Vietri sul Mare in the province of Salerno, dating back to the late 1300s.
One of the earliest recorded individuals bearing the surname MASCOLO was Giovanni Mascolo, who lived in the town of Ravello, near Amalfi, in the late 15th century (approximately 1470-1530). Another notable figure was Antonio Mascolo, a renowned sculptor from the city of Naples, who was active in the early 17th century (c. 1590-1660).
In the 18th century, the name MASCOLO gained prominence through the works of Domenico Mascolo, a celebrated painter and fresco artist from the town of Avellino (1691-1770). His artistic contributions adorned many churches and palaces throughout the region.
During the 19th century, Gaetano Mascolo (1815-1892), a prominent lawyer and political figure from the town of Potenza, played a significant role in the Risorgimento movement, the struggle for Italian unification and independence.
Another notable individual was Raffaele Mascolo (1866-1944), a renowned linguist and philologist from the city of Naples. He made significant contributions to the study of Italian dialects and the preservation of linguistic heritage.
Throughout history, the surname MASCOLO has been associated with various professions, including artisans, intellectuals, and members of the clergy. While the name has maintained its roots in southern Italy, it has also spread to other parts of the country and beyond, with descendants of the MASCOLO family now found in various regions and countries around the world.
Demographics
Among Census respondents with the surname Mascolo, the largest self-reported group is White at 90.1%. The next largest groups are Hispanic (6.4%) and Two or More Races (2.1%).
The bar chart below shows how Mascolo 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 Mascolo 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.
