Origin
The surname Tubo is believed to have originated in Italy, specifically in the region of Tuscany, during the Middle Ages. It is derived from the Italian word "tubo," which means "tube" or "pipe." This suggests that the name may have been associated with occupations or trades related to the production or installation of pipes or tubes.
One of the earliest recorded instances of the surname Tubo can be found in the Florentine Codex, a 16th-century ethnographic work written by the Franciscan friar Bernardino de Sahagún, which mentions a person named Giovanni Tubo who was a master plumber in Florence during the late 15th century.
The name Tubo also appears in various historical documents from the 16th and 17th centuries in the towns of Siena, Pisa, and Lucca, where it was commonly associated with families involved in the construction and maintenance of water supply systems, aqueducts, and irrigation channels.
One notable individual bearing the surname Tubo was Francesco Tubo (1520-1587), a renowned architect and engineer from Siena, who was responsible for the design and construction of several churches and public buildings in his hometown, as well as the renovation of the city's aqueduct system.
Another prominent figure with the surname Tubo was Lucrezia Tubo (1572-1646), a talented painter from Pisa who gained recognition for her portraits and religious works, some of which can still be admired in churches and museums across Tuscany.
In the 18th century, a branch of the Tubo family settled in the city of Naples, where they established a successful business manufacturing and installing lead pipes for water distribution. One member of this family, Giuseppe Tubo (1725-1799), became a respected master plumber and was commissioned to work on several prestigious projects, including the renovation of the city's fountains and water systems.
The surname Tubo can also be found in historical records from other regions of Italy, such as Lombardy and Veneto, although it is less common in these areas. One notable individual from this period was Antonio Tubo (1680-1745), a Venetian merchant and explorer who traveled extensively in the Middle East and documented his journeys in a series of detailed travelogues.
Throughout its history, the surname Tubo has been associated with skilled artisans, architects, engineers, and tradespeople, reflecting its origins related to the production and installation of pipes and tubes, which were essential components in the construction of water supply systems, aqueducts, and other important infrastructure projects.
Demographics
Among Census respondents with the surname Tubo, the largest self-reported group is White at 54.5%. The next largest groups are Asian/Pacific Islander (21.0%) and Black (16.1%).
The bar chart below shows how Tubo 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 Tubo 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.
