Origin
The surname Passetti has its origins in Italy, with the earliest recorded instances dating back to the late 13th century. It is believed to be derived from the Italian word "passo," meaning "step" or "pass." This suggests that the name may have been given to someone who lived near a mountain pass or worked as a guide or toll collector in such areas.
One of the earliest known references to the Passetti name can be found in a document from the city of Perugia, dated 1287. This document mentions a certain "Nicola Passetti," indicating that the name was already in use at that time in the region of Umbria.
In the 14th century, the name began to appear in other parts of central Italy, such as Tuscany and Lazio. Notable individuals from this period include Francesco Passetti (1328-1402), a merchant from Florence, and Giulia Passetti (1352-1428), a nun and writer from Rome.
As the centuries passed, the Passetti family spread across various regions of Italy, with some members achieving prominence in various fields. One such individual was Giovanni Battista Passetti (1592-1670), a renowned architect from Bologna who designed several churches and palaces in his hometown.
Another notable Passetti was Vincenzo Passetti (1698-1772), a painter from Rome whose works can be found in various churches and galleries throughout Italy. His most famous work is the fresco adorning the ceiling of the Basilica of Saint John Lateran.
In the 19th century, the Passetti name gained international recognition through the exploits of Alessandro Passetti (1815-1879), an Italian explorer who led several expeditions to Africa and Asia. He is credited with mapping vast unexplored territories and establishing trade routes with remote regions.
While the Passetti surname has its roots in Italy, it has since spread to other parts of the world through emigration. However, its historical significance remains deeply tied to its Italian heritage and the various individuals who have carried this name throughout the centuries.
Demographics
Among Census respondents with the surname Passetti, the largest self-reported group is White at 85.4%. The next largest groups are Hispanic (9.4%) and Two or More Races (5.2%).
The bar chart below shows how Passetti 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 Passetti 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.
