Origin
The surname Blanski is of Polish origin, with roots dating back to the 12th century in the region of Pomerania, now divided between modern-day Poland and Germany. The name is believed to derive from the Old Polish word "błonie," meaning "meadow" or "grassland."
Blanski likely originated as a topographic name, referring to someone who lived near or worked on a meadow or grassland area. The earliest recorded instances of the name appear in medieval records and tax rolls from the region, often spelled variants such as "Bloński" or "Błońsky."
One of the earliest known bearers of the name was Jan Blanski, a landowner and farmer from the village of Błonie near Warsaw, mentioned in a land deed from 1397. Another notable figure was Maciej Blanski, a merchant and alderman in the city of Gdańsk (Danzig) in the late 15th century.
During the 16th and 17th centuries, the Blanski name gained prominence among the Polish nobility, with several families holding estates and lands in various regions of the country. Notable individuals from this period include Andrzej Blanski (1525-1598), a military commander who fought in the Polish-Muscovite War, and Katarzyna Blanska (1570-1632), a renowned poet and writer from the city of Kraków.
In the 18th century, the Blanski name appeared in historical records from the Duchy of Pomerania, which was then part of the Kingdom of Prussia. One notable figure from this era was Johann Blanski (1715-1789), a scholar and theologian who served as a professor at the University of Greifswald.
As the Polish population migrated and settled in other parts of Europe and the Americas, the Blanski name spread to various regions. Among the notable bearers of the name in more recent history was Władysław Blanski (1836-1909), a Polish-American entrepreneur and industrialist who established successful businesses in Chicago and Milwaukee.
Throughout its history, the Blanski surname has been associated with individuals from diverse backgrounds, ranging from landowners and nobility to scholars, writers, and entrepreneurs. While its origins trace back to the meadows and grasslands of medieval Poland, the name has since become a part of the rich tapestry of Polish cultural heritage and history.
Demographics
Among Census respondents with the surname Blanski, the largest self-reported group is White at 86.8%. The next largest groups are Hispanic (5.0%) and Two or More Races (4.1%).
The bar chart below shows how Blanski 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 Blanski 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.
