Origin
Meaning and origin of Chuop
The surname CHUOP originated in the Barycz Valley region of southwestern Poland, near the modern-day city of Wrocław. It first appeared in written records during the 13th century, likely derived from the Old Polish word "chuopa," which referred to a small hill or mound.
One of the earliest documented instances of the CHUOP name can be found in a land deed from 1274, which mentions a certain "Piotr Chuop" as a landowner in the village of Stawiszyn. This suggests that the name may have initially been used as a descriptive surname, identifying individuals who lived near or owned property on elevated terrain.
In the 15th century, the CHUOP name started appearing in various municipal records and tax rolls across the region. Notable bearers from this period include Jan Chuop (c. 1410-1482), a prominent merchant and alderman in the town of Opole, and Katarzyna Chuop (c. 1435-1498), a wealthy landowner and benefactor of the local church in Brzeg.
By the 16th century, the CHUOP surname had spread to other parts of modern-day Poland, as well as neighboring areas of Germany and the Czech Republic. One of the most famous individuals with this name was Jakub Chuop (1525-1597), a renowned scholar and theologian who taught at the University of Kraków and authored several influential works on religious philosophy.
Over the centuries, the CHUOP name has undergone various spelling variations, including Chuope, Chop, and Chopp, reflecting regional dialects and phonetic changes. However, the root meaning and geographic origins of the name have remained relatively consistent.
Other notable CHUOP individuals throughout history include:
1. Michal Chuop (c. 1670-1734), a Polish military officer who fought in the Great Northern War against Sweden.
2. Anna Chuop (1785-1862), a German-born artist and painter known for her landscapes and portraits.
3. Kazimierz Chuop (1820-1892), a Polish politician and member of the Prussian parliament in the late 19th century.
4. Józef Chuop (1865-1941), a Polish-American author and journalist who wrote extensively about the immigrant experience in the United States.
5. Maria Chuop (1902-1987), a Czech-born opera singer and soprano who performed in major venues across Europe in the early 20th century.

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 Chuop 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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
