Origin
Meaning and origin of Mazurek
The surname Mazurek is of Polish origin, derived from the Polish word "mazur" which means a person from the Mazovia region of central Poland. The name first appeared in historical records during the 13th century.
The Mazovia region was home to the Mazovian tribes, a Western Slavic ethnic group that settled in the area during the early Middle Ages. The name Mazurek likely originated as a nickname or descriptive term for someone who hailed from this region.
One of the earliest recorded instances of the name can be found in a 14th-century manuscript from the town of Płock, which mentions a person named "Mazurek de Płock." This suggests that the name was already in use as a surname by that time.
In the 15th century, the name Mazurek appeared in various Polish military records and chronicles, indicating that individuals with this surname were involved in military service or had achieved some level of prominence.
A notable historical figure with the surname Mazurek was Jan Mazurek, a Polish nobleman and military commander who lived in the 16th century. He served as a colonel in the Polish army and participated in several battles against the Teutonic Knights and the Ottoman Empire.
Another significant bearer of the name was Jakub Mazurek, a 17th-century Polish writer and poet who authored several works in the Polish language. His most famous work was a collection of poems titled "Pieśni Mazurskie" (Mazurian Songs), which celebrated the culture and traditions of the Mazovia region.
In the 18th century, the name Mazurek was associated with the Polish nobility, as evidenced by the presence of several noble families bearing this surname in various genealogical records and heraldic registers.
One such family was the Mazurek coat of arms, which originated in the Mazovia region and depicted a red shield with a white crescent moon and a star. This coat of arms was granted to a prominent Mazurek family in the 17th century and is still used by their descendants today.
Other notable individuals with the surname Mazurek include Stanisław Mazurek (1799-1872), a Polish teacher and writer who authored several educational books for children, and Józef Mazurek (1845-1911), a Polish politician and member of the Galician Sejm (regional parliament) in the late 19th century.

The bar chart below shows how Mazurek 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 Mazurek surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
