Origin
The surname STEFANSKI originated in Poland in the 15th century. It is derived from the Polish personal name Stefan, which comes from the Greek name Stephanos, meaning "crown" or "wreath."
The earliest known record of the surname STEFANSKI appears in a Polish census document from 1478, where it was spelled "Stiefansky." This spelling variation likely arose due to regional dialects and the influence of other languages in the area at the time.
In the 16th century, the surname STEFANSKI can be found in various Polish parish records and land ownership documents, particularly in the regions of Silesia and Lesser Poland. Some notable historical figures with this surname include Jan STEFANSKI (1583-1645), a Polish nobleman and landowner, and Mikołaj STEFANSKI (1612-1687), a Polish Catholic priest and author.
The surname STEFANSKI is also associated with several notable place names in Poland. For example, the village of Stefanów in the Lublin Voivodeship was likely named after an early settler with the surname STEFANSKI. Similarly, the town of Stefanowo in the Masovian Voivodeship may have derived its name from the same source.
Throughout the centuries, several notable individuals have borne the surname STEFANSKI. Some examples include:
1. Teodor STEFANSKI (1838-1910), a Polish painter and art teacher.
2. Stanisław STEFANSKI (1877-1944), a Polish engineer and inventor of the first successful mine detector.
3. Wacław STEFANSKI (1911-1994), a Polish footballer who played for the Polish national team in the 1930s.
4. Zygmunt STEFANSKI (1923-2008), a Polish politician and member of the Sejm (Polish parliament) during the communist era.
5. Krzysztof STEFANSKI (born 1954), a Polish actor and theater director.
The surname STEFANSKI has since spread beyond Poland due to migration and diasporas, but its roots can be traced back to the 15th century in the Polish regions of Silesia and Lesser Poland.
Demographics
Among Census respondents with the surname Stefanski, the largest self-reported group is White at 94.0%. The next largest groups are Hispanic (2.9%) and Two or More Races (2.2%).
The bar chart below shows how Stefanski 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 Stefanski 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 Stefanski (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.
