Origin
The surname Baur is of German origin, originating from the southern regions of Germany during the late medieval period. The name is believed to have derived from the Old High German word "bur," which referred to a farmer or peasant. This suggests that the name may have initially been an occupational surname given to those who worked the land or were involved in agricultural pursuits.
One of the earliest recorded instances of the Baur surname can be traced back to the 13th century in the region of Bavaria. The name appeared in various medieval records and documents, including the Codex Diplomaticus Saxoniae Regiae, a collection of charters and records from Saxony dating back to the 10th century.
In the 14th century, the Baur surname was also found in the Ölbücher, which were official tax records from the city of Nuremberg. These records provide valuable insights into the prevalence and distribution of surnames during that era.
Among the notable individuals bearing the Baur surname, one of the earliest was Johannes Baur (c. 1477-1550), a German theologian and Protestant reformer from Nuremberg. He played a significant role in the Reformation movement and was a close associate of Martin Luther.
Another prominent figure was Johann Wilhelm Baur (1607-1642), a German engraver and printmaker known for his intricate etchings and engravings of landscapes and architectural scenes. His works are highly regarded and can be found in numerous museums and collections worldwide.
In the 19th century, Ferdinand Christian Baur (1792-1860) was a renowned German theologian and scholar who made significant contributions to the field of biblical criticism. He is particularly known for his influential work on the historical development of early Christianity.
The Baur surname also has ties to several notable place names in Germany. For example, the town of Bärnau in Bavaria is believed to have derived its name from the Baur surname, indicating a possible connection to the area's early settlers.
Other notable individuals with the Baur surname include:
1. Adolf Baur (1835-1910), a German architect and city planner
2. Constanze Baur (born 1976), a German professional tennis player
3. Gustav Baur (1809-1873), a German botanist and plant collector
4. Wilhelm Baur (1839-1920), a German painter and illustrator
The Baur surname has a rich history, rooted in the agricultural traditions of medieval Germany. Its enduring presence across centuries and its association with notable individuals in various fields reflect the diverse paths taken by those who bear this name.
Demographics
Among Census respondents with the surname Baur, the largest self-reported group is White at 92.4%. The next largest groups are Hispanic (3.4%) and Two or More Races (2.9%).
The bar chart below shows how Baur 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 Baur 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.
