Origin
The surname Rotondo has its origins in Italy, dating back to the 14th century. It is derived from the Italian word "rotondo," which means "round" or "circular." This suggests that the name may have been initially given as a descriptive nickname to someone of a rotund or round physique.
The earliest known record of the name can be traced back to the city of Naples, where a certain Giovanni Rotondo was mentioned in a legal document from the year 1375. In the following centuries, the name spread to other parts of southern Italy, particularly in the regions of Campania, Basilicata, and Calabria.
One of the earliest documented individuals bearing the Rotondo surname was Girolamo Rotondo, a renowned painter from the city of Messina in Sicily, who lived from around 1470 to 1535. His works, particularly his religious frescoes and altarpieces, can still be found in various churches across Sicily and southern Italy.
In the 17th century, a notable figure named Niccolò Rotondo (1588-1657) gained prominence as a Neapolitan architect and engineer. He was responsible for the design and construction of several notable buildings in Naples, including the Church of Santi Apostoli and the Palazzo Reale di Napoli.
Another individual of historical significance was Francesco Rotondo (1735-1804), a Neapolitan lawyer and politician who played a significant role in the establishment of the Parthenopean Republic, a short-lived revolutionary republic in Naples during the late 18th century.
In the 19th century, the Rotondo surname gained further recognition through the life and works of Vincenzo Rotondo (1835-1912), an Italian sculptor and painter from the town of Bari in Apulia. His sculptures and paintings, which often depicted scenes from rural life and folklore, became widely celebrated throughout Italy.
Variations of the name, such as Rotondaro, Rotondella, and Rotondino, can also be found in various parts of Italy, particularly in the southern regions. These variations often reflect the influence of local dialects or the addition of diminutive or augmentative suffixes to the original name.
Demographics
Among Census respondents with the surname Rotondo, the largest self-reported group is White at 91.7%. The next largest groups are Hispanic (4.6%) and Two or More Races (2.7%).
The bar chart below shows how Rotondo 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 Rotondo 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.
