Origin
Meaning and origin of Bauder
The surname Bauder is of German origin, derived from the occupational name "Bauder" or "Bauer," which means "builder" or "farmer." This name can be traced back to the Middle Ages, around the 12th to 15th centuries, when it was common for people to adopt surnames based on their occupations or places of residence.
The earliest recorded instances of the surname Bauder can be found in various German regions, such as Bavaria, Saxony, and Swabia. The name was particularly prevalent in areas with a strong agricultural tradition, where many people worked as farmers or builders. It is also possible that the name was influenced by the Old High German word "būr," which meant "dweller" or "peasant."
In the 14th century, a man named Johannes Bauder was mentioned in the records of the city of Augsburg, Bavaria. This is one of the earliest known references to the surname. Another notable early record is from the 15th century, where a certain Hans Bauder was listed as a landowner in the town of Rothenburg ob der Tauber, in present-day Bavaria.
Over the centuries, the surname Bauder has undergone various spelling variations, such as Bauer, Baur, Bauwer, and Bawer, reflecting regional dialects and scribal variations. Some of these alternate spellings may have evolved into distinct surnames in their own right.
Several notable individuals have borne the surname Bauder throughout history. One example is Johann Bauder (1515-1573), a German Protestant theologian and reformer who played a significant role in the Protestant Reformation in Saxony. Another is Konrad Bauder (1811-1890), a German-American Lutheran pastor and theologian who served as the president of Concordia Seminary in St. Louis, Missouri.
Other notable individuals with the surname Bauder include:
1. Theodor Bauder (1824-1906), a German architect and builder who designed several notable buildings in Darmstadt, Germany.
2. Wilhelm Bauder (1818-1898), a German Protestant theologian and author who served as a professor at the University of Giessen.
3. Ernst Bauder (1873-1948), a German painter and illustrator known for his landscape and genre paintings.
4. Karl Bauder (1888-1958), a German politician and member of the Nazi Party during the Third Reich.

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 Bauder 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 Bauder (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
