Origin
The surname RUCK is of German origin, deriving from the Middle High German word 'rucke', meaning a hill or ridge. The name first emerged in the 14th century in the regions of Bavaria and Swabia, where many families adopted locational surnames based on the prominent geographical features near their homesteads.
One of the earliest recorded mentions of the name RUCK can be found in the Rottweil town records of 1372, where a Hans Ruck is listed as a resident. The name also appears in various medieval manuscripts and charters, such as the Würzburg Diocesan Records from the late 15th century, which reference a family of Rucks living in the vicinity.
In the 16th century, the name RUCK began to spread beyond its original regional boundaries, with families bearing this surname appearing in the records of towns and villages across southern Germany. Notable individuals from this era include Johann Ruck (1499-1567), a renowned theologian and reformer from Nuremberg, and Hans Ruck (1521-1598), a master stonemason who worked on several prominent cathedrals in Bavaria.
As the RUCK families prospered and migrated, the name found its way into other parts of Europe and beyond. In the 17th century, a branch of the family settled in the Netherlands, where the name was recorded as 'Ruck' and 'Rucke'. Around this time, the name also appeared in the records of German emigrants to the British colonies in North America.
Over the centuries, the RUCK surname has been associated with various notable figures, such as Friedrich Ruck (1746-1819), a German philosopher and author who wrote extensively on ethics and moral philosophy. In the 19th century, Johann Ruck (1825-1899) was a prominent architect responsible for designing several iconic buildings in Munich.
Another significant figure was Carl Ruck (1870-1938), a German-born American businessman who founded the Ruck Brewing Company in St. Louis, Missouri, which became one of the largest breweries in the United States during the early 20th century. More recently, Peter Ruck (1940-2022) was a renowned German journalist and author known for his investigative reporting on political and social issues.
Demographics
Among Census respondents with the surname Ruck, the largest self-reported group is White at 86.8%. The next largest groups are Hispanic (5.3%) and Black (3.7%).
The bar chart below shows how Ruck 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 Ruck 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.
