Origin
The surname Ruedebusch is of German origin, originating in the late Middle Ages around the 14th or 15th century. It is a locative name, derived from a place name likely referring to a small village or hamlet where the name bearers once lived or originated from. The name itself is composed of two elements - "Ruede" which may have evolved from the Old German word "rüden" meaning to clear land, and "busch" meaning bush or shrub.
This suggests the name Ruedebusch could have referred to a settlement or homestead located in a cleared area surrounded by bushes or shrubland. The earliest recorded instances of the name appear in various medieval German records and documents from regions such as Saxony, Bavaria, and the Rhineland. One of the earliest known bearers of the name was Johann Ruedebusch, a farmer from the village of Rüdesheim in the Rhineland, mentioned in a land deed dated 1486.
In the 16th century, the name appears in the records of the city of Nuremberg, with a certain Hans Ruedebusch listed as a merchant and guild member in 1534. Another notable individual was Christoph Ruedebusch, a Lutheran pastor born in Erfurt in 1598, who authored several theological treatises during the Reformation era.
As the surname spread across German-speaking regions, local variations in spelling and pronunciation emerged, such as Rüdebusch, Rüdebüsch, and Rüdebüscher. In the 18th century, a branch of the family settled in the Palatinate region, where the name took on the spelling Rüdebüsch. One prominent bearer from this line was Johann Adam Rüdebüsch, a celebrated clockmaker born in Zweibrücken in 1744.
Another notable figure was Wilhelm Ruedebusch, a German-American pioneer and settler who emigrated to Wisconsin in the mid-19th century, establishing a successful farm and becoming a respected community leader in the town of Lebanon.
Other historical figures bearing the Ruedebusch surname include Hermann Ruedebusch, a 19th-century architect from Hanover who designed several notable buildings in northern Germany, and Ernst Ruedebusch, a German-born artist and illustrator active in New York City in the early 20th century.
Demographics
Among Census respondents with the surname Ruedebusch, the largest self-reported group is White at 97.5%. The next largest groups are Hispanic (0.8%) and Asian/Pacific Islander (0.8%).
The bar chart below shows how Ruedebusch 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 Ruedebusch surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Ruedebusch (2000, 2010, 2020).
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.
