Origin
The surname Pisani is of Italian origin, with roots tracing back to the 14th century in the Veneto region of northern Italy. The name is derived from the Italian word "pisano," meaning "of Pisa," suggesting that the earliest bearers of the name hailed from the city of Pisa or its surrounding areas.
One of the earliest recorded instances of the Pisani name can be found in the Venetian Republic's historical archives, where members of the noble Pisani family held prominent positions in the government and military during the 14th and 15th centuries. Notably, Vittore Pisani (1324-1380) was a renowned Venetian admiral who played a crucial role in the Republic's naval victories against the Genoese during the Venetian-Genoese Wars.
The Pisani name also appears in various medieval manuscripts and records from the Italian Renaissance period. For instance, Niccolò Pisani (1459-1537) was a skilled painter and architect from Udine, whose works adorned several churches and palaces in the region.
In the 16th century, the Pisani family established themselves as influential landowners and patrons of the arts in the Veneto region. Giovanni Pisani (1548-1626), a wealthy nobleman and art collector, commissioned some of the most notable works by Venetian masters, including Tintoretto and Veronese.
As the Pisani name spread throughout Italy and beyond, it acquired various spellings and variations, such as Pisano, Pisanis, and Pisan. One notable bearer of the name was the French explorer and writer, Paul-Émile Pisani (1812-1891), who documented his travels in the Middle East and North Africa.
Other notable individuals with the Pisani surname include the Italian composer and conductor, Gabriele Pisani (1890-1968), known for his operas and orchestral works, and the American politician, Frank Pisani (1924-2015), who served as the mayor of Waterbury, Connecticut, from 1985 to 1991.
Demographics
Among Census respondents with the surname Pisani, the largest self-reported group is White at 92.3%. The next largest groups are Hispanic (5.0%) and Two or More Races (1.7%).
The bar chart below shows how Pisani 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 Pisani surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Pisani (2000, 2010, 2020).
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.
