Origin
The surname RUTKOWSKI originated in Poland during the Middle Ages. It is derived from the Polish word "rutki," meaning "small brooks" or "creeks," suggesting that the name may have been given to someone who lived near such a geographic feature.
RUTKOWSKI is a toponymic surname, meaning it was originally derived from a place name. It likely originated in one of the numerous villages or towns named Rutki or Rutkowo that are found throughout different regions of Poland.
One of the earliest recorded instances of the name can be found in a document from the town of Rutki in Masovia, dating back to the early 15th century. This document mentions a landowner named Jan RUTKOWSKI.
Another notable early reference to the name is in the Metryka Koronna, which was a collection of official records kept by the Polish-Lithuanian Commonwealth. An entry from 1468 mentions a Stanislaw RUTKOWSKI, who was a nobleman from the Dobrzyń Land region.
During the 16th and 17th centuries, the name became more widespread across various parts of Poland. Some notable individuals with the surname included Marcin RUTKOWSKI (1553-1624), a Catholic priest and theologian from Mazovia, and Hieronim RUTKOWSKI (1619-1695), a Jesuit missionary who traveled to China and wrote about his experiences there.
In the 18th century, Tomasz RUTKOWSKI (1700-1768) was a prominent mathematician and astronomer who made significant contributions to the study of comets and planetary orbits.
As the name spread beyond Poland's borders, it also appeared in other parts of Europe and the Americas. One notable example is Józef RUTKOWSKI (1873-1949), a Polish-American writer and journalist who founded several Polish-language newspapers in the United States.
Throughout its history, the surname RUTKOWSKI has been associated with various professions, including landowners, clergy, academics, and writers. While originally concentrated in Poland, it has since become more widely dispersed across different countries and continents.
Demographics
Among Census respondents with the surname Rutkowski, the largest self-reported group is White at 93.9%. The next largest groups are Hispanic (2.5%) and Two or More Races (2.2%).
The bar chart below shows how Rutkowski 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 Rutkowski 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.
