Origin
The surname Polacco is an Italian name with origins tracing back to the medieval era. It is a locational surname derived from the name of the town of Pollacco, located in the province of Bari in the Apulia region of southern Italy. The name Pollacco itself comes from the Latin word "Apuli" or "Apulicus," which referred to the ancient Apulian people who inhabited this area.
Historical records show that the Polacco family was established in the town of Pollacco as early as the 13th century. One of the earliest recorded instances of the name appears in the "Codice Diplomatico Barese," a collection of medieval documents from the city of Bari, where a certain "Riccardo Polacco" is mentioned in a document dated 1276.
In the 14th century, there are records of a prominent noble family with the surname Polacco residing in the town of Monopoli, also in the Apulia region. This family is believed to have descended from the original Polacco lineage from Pollacco.
One notable figure with the surname Polacco was Francesco Polacco, a 16th-century Italian painter and architect born in Monopoli around 1540. He is best known for his work on the Basilica of Santa Maria Maggiore in Rome.
Another significant individual was Vittorio Polacco, an Italian lawyer and politician born in Venice in 1858. He served as a member of the Italian Parliament and was a prominent advocate for workers' rights.
In the realm of literature, we have Goffredo Polacco, an Italian poet and writer born in Trieste in 1903. He is renowned for his contributions to the Italian literary movement known as "Ermetismo."
Giorgio Polacco, born in Legnano, Italy, in 1889, was a notable Italian physician and researcher who made significant contributions to the field of hematology and the study of blood disorders.
Lastly, Arrigo Polacco, born in Rome in 1906, was an Italian actor and director who had a successful career in both Italian and American cinema during the mid-20th century.
While the name Polacco is most commonly found in Italy, particularly in the southern regions, it has also spread to other parts of the world through Italian emigration over the centuries.
Demographics
Among Census respondents with the surname Polacco, the largest self-reported group is White at 89.2%. The next largest groups are Asian/Pacific Islander (4.9%) and Hispanic (3.9%).
The bar chart below shows how Polacco 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 Polacco 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.

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.
