Origin
The surname Chmielewski is of Polish origin and can be traced back to the 16th century. It is a toponymic name derived from the Polish word "chmiel," meaning "hops." This suggests that the name may have originated from a place where hops were grown or processed.
One of the earliest recorded instances of the name Chmielewski can be found in a 16th-century document from the town of Poznań, Poland. The document mentions a certain Jan Chmielewski, a landowner and farmer.
In the 17th century, the name appeared in various records from the regions of Mazovia and Greater Poland. There are mentions of a Michał Chmielewski, a nobleman who lived in the village of Chmielnik near Warsaw, and a Stanisław Chmielewski, a merchant from the city of Kalisz.
The 18th century saw the rise of a prominent Chmielewski family in the town of Tykocin, in what is now northeastern Poland. One of the notable members of this family was Kazimierz Chmielewski (1745-1823), a Polish military officer who fought in the Kościuszko Uprising against Russian forces.
In the 19th century, the name Chmielewski became more widespread across different regions of Poland. One notable figure was Józef Chmielewski (1810-1879), a Polish painter and sculptor who studied at the Imperial Academy of Arts in St. Petersburg.
Another significant figure was Władysław Chmielewski (1848-1912), a Polish writer and journalist who was a prominent advocate for Polish independence from Russian rule. He founded several Polish-language newspapers and was active in various patriotic organizations.
As the Polish diaspora grew in the late 19th and early 20th centuries, the name Chmielewski spread to other parts of the world. One example is Benedykt Chmielewski (1700-1763), a Polish Jesuit missionary who traveled to South America and established several missions in present-day Bolivia and Brazil.
Throughout its history, the surname Chmielewski has been associated with various professions, including landowners, merchants, artists, writers, and military personnel. While the name originated in Poland, it has since been carried by individuals of Polish descent around the globe.
Demographics
Among Census respondents with the surname Chmielewski, the largest self-reported group is White at 93.1%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.4%).
The bar chart below shows how Chmielewski 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 Chmielewski 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.
