Origin
The surname Karpinski originated in Poland, where it first appeared in the 16th century. It is a Polish habitational name derived from the place name Karpin or Karpiny, which is derived from the Slavic root word "karp" meaning "carp" or "carp fish". This suggests that the name may have referred to someone who lived near a body of water populated by carp or someone who was a fisherman specializing in catching carp.
The earliest known record of the Karpinski surname can be found in the "Akta Metrykalne" (Metrical Records) of the town of Kielce, Poland, from the year 1564. The entry mentions a certain "Maciej Karpinski", who was likely one of the first to bear this surname.
In the 17th century, the Karpinski name can be found in various Polish records, such as the "Księgi Metrykalne" (Parish Registers) of the towns of Krakow and Poznan. One notable bearer of this surname from this period was Jan Karpinski (1580-1653), a Polish poet and writer who is considered one of the foremost representatives of Polish Renaissance literature.
During the 18th and 19th centuries, the Karpinski surname spread throughout Poland and into other parts of Eastern Europe, particularly Russia and Ukraine. A famous bearer of this name was Franciszek Karpinski (1741-1825), a Polish poet, playwright, and fabulist who is often referred to as the "Polish La Fontaine".
Another notable Karpinski was Wacław Karpinski (1809-1847), a Polish mathematician and educator who made significant contributions to the field of algebraic geometry. He is best known for his work on the theory of algebraic curves and surfaces.
In the 20th century, one of the most prominent individuals with the Karpinski surname was Jakub Karpinski (1927-2010), a Polish mathematician and computer scientist who is considered a pioneer in the field of computational complexity theory. He made important contributions to the study of NP-complete problems and the development of efficient algorithms.
Demographics
Among Census respondents with the surname Karpinski, the largest self-reported group is White at 93.9%. The next largest groups are Two or More Races (3.0%) and Hispanic (2.0%).
The bar chart below shows how Karpinski 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 Karpinski surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Karpinski (2000, 2010, 2020).
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.
