Origin
The surname Pietrak is of Polish origin, originating from the region of Silesia in southwestern Poland. It can be traced back to the 16th century when it was derived from the personal name "Piotr," which is the Polish equivalent of the name Peter.
The name Pietrak likely originated as a diminutive form of Piotr, with the suffix "-ak" indicating a smaller or younger version. This naming convention was common in Poland and other Slavic countries, where surnames often evolved from personal names or nicknames.
One of the earliest recorded instances of the name Pietrak can be found in the Liber Beneficiorum, a historical record of land ownership and benefices in the Archdiocese of Gniezno, dating back to the late 15th century. This document mentions a "Pietrak de Gostynin," suggesting the name was present in the town of Gostynin at that time.
In the 17th century, the name Pietrak appeared in various parish records and court documents across Silesia and neighboring regions. For instance, a Jan Pietrak was recorded as a landowner in the village of Zielona Góra in 1612, while a Marcin Pietrak was listed as a merchant in the town of Opole in 1658.
One notable figure with the surname Pietrak was Franciszek Pietrak (1786-1853), a Polish priest and editor who played a significant role in the development of Polish literature during the Romantic period. He founded and edited the literary journal "Przyjaciel Ludu" (Friend of the People), which aimed to promote education and cultural awareness among the Polish population.
Another individual of historical importance was Wincenty Pietrak (1871-1945), a Polish architect and urban planner who designed numerous residential and public buildings in the city of Lodz during the late 19th and early 20th centuries. His works, characterized by a blend of Art Nouveau and Neo-Renaissance styles, contributed significantly to the architectural heritage of the city.
In the 20th century, Stanisław Pietrak (1910-1992) gained recognition as a Polish military officer and politician. He served in the Polish resistance during World War II and later became a member of the Polish parliament, representing the Polish United Workers' Party.
Additionally, the name Pietrak has been associated with several notable athletes, including Jerzy Pietrak (born 1950), a former Polish football player who represented the national team in the 1970s, and Tomasz Pietrak (born 1974), a Polish boxer who won a bronze medal in the lightweight division at the 1996 Olympic Games in Atlanta.
Demographics
Among Census respondents with the surname Pietrak, the largest self-reported group is White at 91.2%. The next largest groups are Two or More Races (3.9%) and Hispanic (2.0%).
The bar chart below shows how Pietrak 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 Pietrak 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.
