Origin
The surname PIROK is thought to have originated in Poland, with its roots tracing back to the 15th century. The name is believed to be derived from the Polish word "piroha," which refers to a type of filled dumpling or pastry. This suggests that the name may have been associated with someone who was a maker or seller of these dumplings.
One of the earliest recorded instances of the PIROK surname can be found in the 1564 parish records of the town of Krakow, where a certain Jan PIROK is mentioned as a resident. This provides evidence that the name was in use in Poland during the late 16th century.
In the 17th century, the PIROK name appears in various Polish court documents and land records, indicating that members of this family were landowners and held positions of some prominence within their local communities.
Notable individuals with the PIROK surname include Stefan PIROK (1582-1641), a Polish poet and playwright who wrote several works in the baroque style during the early 17th century. Another prominent figure was Jadwiga PIROK (1705-1772), a landowner and philanthropist who donated funds for the construction of a church and a school in her hometown of Bydgoszcz.
As the PIROK family spread across Poland and into neighboring regions, variations in the spelling of the name emerged. Some examples include PYROK, PYROKG, and PIROCH, which can be found in historical records from the 18th and 19th centuries.
One notable bearer of the PIROK name was Franciszek PIROK (1819-1892), a Polish artist who specialized in landscape paintings and was known for his depictions of the countryside around Warsaw.
In the late 19th century, the PIROK surname began to appear in records of Polish immigrants who settled in various parts of the United States and Canada, as families sought new opportunities and a better life abroad.
Throughout its history, the PIROK surname has maintained a strong connection to its Polish roots, with many bearers of the name proudly tracing their ancestry back to the regions where the name first emerged centuries ago.
Demographics
Among Census respondents with the surname Pirok, the largest self-reported group is White at 91.5%. The next largest groups are Two or More Races (7.6%) and Hispanic (0.8%).
The bar chart below shows how Pirok 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 Pirok 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.
