Origin
The surname SAUER has its origins in Germany and dates back to the 12th century. It is derived from the Middle High German word "sur," meaning sour or bitter, and was likely initially used as a nickname for someone with a sharp or sour disposition.
One of the earliest recorded instances of the name can be found in the Codex Diplomaticus Anhaltinus, a collection of historical documents from the Anhalt region of Germany, dating back to the 13th century. The name Sauer appears several times in these records, indicating its presence in the area during that time period.
The name SAUER also has connections to various place names throughout Germany, such as Sauerlach in Bavaria and Sauerland in North Rhine-Westphalia. These place names may have influenced the spread and adoption of the surname in those regions.
Notable individuals with the surname SAUER include the German astronomer Johann Sauer (1545-1611), who made significant contributions to the study of comets and the development of astronomical instruments. Another prominent figure was the German artist and printmaker Georg Sauer (1617-1667), known for his intricate etchings and engravings.
In the 18th century, Johann Sauer (1695-1768) was a renowned printer and publisher in Germantown, Pennsylvania, famous for printing the first German-language Bible in America in 1743. This publication played a vital role in preserving the German language and culture among early German settlers in North America.
Continuing into the 19th century, Christoph Sauer (1795-1865) was a German-American journalist and publisher who founded several influential German-language newspapers in the United States, including the Baltimore Wecker and the Philadelphia Demokrat.
Another notable figure was the German-American author and philosopher Carl Sauer (1889-1975), who made significant contributions to the field of cultural geography and is considered one of the founders of the Berkeley School of Geography.
Throughout its history, the surname SAUER has been carried by individuals from various professions and backgrounds, spanning the fields of science, arts, publishing, and academia, among others.
Demographics
Among Census respondents with the surname Sauer, the largest self-reported group is White at 92.4%. The next largest groups are Hispanic (3.2%) and Two or More Races (2.9%).
The bar chart below shows how Sauer 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 Sauer 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.
