Origin
The surname Bischoff originated in Germany during the Middle Ages. It is derived from the German word "Bischof," which means "bishop." This suggests that the earliest bearers of this name may have been employed by or associated with a bishop or church official.
One of the earliest recorded instances of the Bischoff name can be found in the Codex Diplomaticus Saxoniae, a collection of medieval documents from the region of Saxony, dating back to the 12th century. The name is also mentioned in various other historical records from German-speaking regions during this period.
In the 14th century, a notable figure named Johannes Bischoff was a prominent scholar and rector at the University of Vienna. He lived from around 1340 to 1410 and made significant contributions to the field of theology during his time.
Another early bearer of the Bischoff name was Gottfried Bischoff, a German poet and writer who lived from 1497 to 1560. He is best known for his allegorical work "Teurdank," which was published in 1517 and considered an important literary achievement of the Renaissance era.
In the 17th century, a notable individual named Johann Bischoff (1624-1693) was a German mathematician and astronomer. He made important contributions to the field of celestial mechanics and is regarded as one of the pioneers of modern astronomy.
During the 18th century, the Bischoff name was also associated with the town of Bischofsheim, located in the state of Hesse, Germany. This place name likely derived from the German words "Bischof" (bishop) and "Heim" (home), suggesting a connection between the surname and this particular town.
As the Bischoff name spread throughout Germany and beyond, it was also adopted by several notable figures in various fields, including Johann Nicolaus Bischoff (1749-1831), a German botanist and naturalist, and Theodor Ludwig Wilhelm Bischoff (1807-1882), a renowned German anatomist and embryologist.
Demographics
Among Census respondents with the surname Bischoff, the largest self-reported group is White at 92.8%. The next largest groups are Hispanic (3.6%) and Two or More Races (2.3%).
The bar chart below shows how Bischoff 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 Bischoff 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.
