Origin
The surname STUMO is of Italian origin, tracing its roots back to the 14th century. It is believed to have originated in the region of Tuscany, where it was derived from the Italian word "stumo," which means "flock" or "herd." This suggests that the name may have been initially associated with occupations related to shepherding or livestock management.
One of the earliest recorded mentions of the STUMO surname can be found in the Florentine Priorista of 1382, where a certain Giovanni di Stumo is listed as a prominent citizen of Florence. This document provides valuable insight into the prevalence of the name in the area during the late Middle Ages.
In the 16th century, the STUMO name appears in the records of the Republic of Venice, particularly in the city of Verona. Notable individuals from this period include Girolamo STUMO (1520-1588), a renowned scholar and humanist who authored several works on philosophy and rhetoric.
As the STUMO family expanded throughout Italy, they established themselves in various regions. In the 18th century, a branch of the family settled in the Sicilian town of Noto, where they played a significant role in the local economy and politics. One prominent figure was Vincenzo STUMO (1725-1793), a successful merchant and landowner who served as a councilor in the municipal government.
The name STUMO also found its way to the island of Sardinia, where it is still present today. One of the earliest recorded instances of the name in Sardinia dates back to the late 17th century, with the birth of Antonio STUMO (1679-1743) in the town of Sassari.
Outside of Italy, the STUMO surname has been documented in other parts of Europe, likely due to migration and trade. In the 19th century, a family of STUMOs resided in the Spanish city of Barcelona, where they owned a successful textile business. One notable member was Enrique STUMO (1845-1912), who served as a city councilor and was actively involved in local politics.
Throughout its history, the STUMO surname has been associated with various occupations, including shepherding, agriculture, academia, commerce, and public service. While the name may have originated from humble beginnings, it has evolved to encompass a diverse range of individuals and professions over the centuries.
Demographics
Among Census respondents with the surname Stumo, the largest self-reported group is White at 90.9%. The next largest groups are Hispanic (4.5%) and Asian/Pacific Islander (2.7%).
The bar chart below shows how Stumo 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 Stumo 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.
