Origin
The surname STUPAK is of Polish origin, with its roots dating back to the 16th century. It is believed to have originated in the region of Lesser Poland, particularly in the areas surrounding the cities of Krakow and Tarnow.
The name STUPAK is derived from the Polish word "stopa," meaning "foot." It is likely that the name was initially given as a descriptive nickname to someone with a distinctive gait or foot-related characteristic. Over time, this nickname evolved into a hereditary surname.
One of the earliest recorded instances of the surname STUPAK can be found in the church records of the village of Rajbrot, located near Krakow, where a certain Jan STUPAK was mentioned in an entry dated 1587.
In the 17th century, the name appears in various Polish historical documents, including tax records and land registries. For instance, a Marcin STUPAK was listed as a landowner in the town of Bochnia in 1642.
Notable individuals bearing the surname STUPAK include:
1. Konstanty STUPAK (1838-1901), a Polish painter and art professor at the Academy of Fine Arts in Krakow.
2. Mieczysław STUPAK (1879-1958), a Polish military officer and recipient of the Virtuti Militari, Poland's highest military decoration.
3. Bartłomiej STUPAK (1920-1944), a Polish resistance fighter during World War II who was executed by the German occupiers.
4. Jerzy STUPAK (1944-2022), a Polish actor known for his roles in numerous theatre productions and films.
5. Bartosz STUPAK (born 1983), a contemporary Polish novelist and screenwriter, acclaimed for his works exploring themes of identity and social issues.
While the name STUPAK is most prevalent in Poland, it has also been recorded in other Slavic countries, such as Ukraine and Belarus, likely due to migration patterns over the centuries. Some variations in spelling, like STUPAC or STUPACZYK, can also be found.
Demographics
Among Census respondents with the surname Stupak, the largest self-reported group is White at 95.8%. The next largest groups are Hispanic (2.7%) and Two or More Races (1.3%).
The bar chart below shows how Stupak 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 Stupak 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.
