Origin
The surname Rudebeck has its origins in Sweden, tracing back to the 17th century. It is derived from the old Swedish words "ryd" meaning a cleared area of land, and "beck" meaning a stream or brook. This suggests the name originally referred to someone who lived near a clearing by a stream or brook.
One of the earliest recorded instances of the name Rudebeck can be found in the Swedish parish records from the late 1600s. The spelling variations included Rydebeck and Rudebäck. These early examples are often linked to specific locations in central Sweden where the name holders resided.
Notable individuals with the surname Rudebeck include Johan Rudebeck (1669-1718), a Swedish priest and writer who authored religious texts. Another was Erik Rudebeck (1679-1753), a Swedish lawyer and President of the Svea Court of Appeal in Stockholm.
In the 19th century, Carl Olof Rudebeck (1807-1881) was a Swedish botanist and professor at the University of Lund. He made significant contributions to the field of plant taxonomy and authored several scientific publications.
Anders Rudebeck (1843-1925) was a Swedish architect and engineer, renowned for his work on the Stockholm City Hall and other notable buildings in the city.
Moving into the 20th century, Claes Rudebeck (1907-1992) was a Swedish diplomat and ambassador, serving in various countries including the United States and the Soviet Union.
Throughout its history, the Rudebeck surname has maintained its Swedish roots and associations with specific geographic locations in Sweden where the name holders originated and lived. While not a widely dispersed surname globally, it remains an important part of Swedish genealogical records and history.
Demographics
Among Census respondents with the surname Rudebeck, the largest self-reported group is White at 97.1%. The next largest groups are Two or More Races (2.9%).
The bar chart below shows how Rudebeck 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 Rudebeck 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.
