Origin
The surname Zahn is of German origin, originating in the early medieval period. It is derived from the Old High German word "zand" or "zan," meaning "tooth" or "tusk." This suggests that the name may have been initially bestowed as a descriptive nickname for someone with prominent teeth or perhaps a profession related to teeth, such as a dentist or ivory carver.
One of the earliest recorded instances of the surname Zahn can be found in the Codex Traditionum Monasterii Sancti Galli, a medieval cartulary from the Abbey of St. Gallen in present-day Switzerland, dating back to the 9th century. The name is also mentioned in various German town and church records from the 13th and 14th centuries, with variations in spelling such as "Zän," "Zan," and "Zahn."
In the 15th century, the name Zahn appeared in the Bützower Häuserbuch, a house book from the town of Bützow in Mecklenburg, Germany. This document recorded the names of property owners and residents within the town. During this time, the surname was also found in other regions of Germany, including Bavaria and Saxony.
One notable figure bearing the surname Zahn was Johann Zahn (1641-1707), a German Protestant minister and polymath known for his works on optics, acoustics, and other scientific subjects. Another individual of historical significance was Johann Karl Wilhelm Zahn (1771-1853), a German theologian and writer who served as a professor at the University of Leipzig.
In the 19th century, the surname Zahn was carried by several prominent individuals, including Gustav Zahn (1800-1876), a German painter and lithographer, and Friedrich Zahn (1869-1950), a German Protestant theologian and New Testament scholar. Additionally, Albert Zahn (1846-1904) was a German architect responsible for designing numerous buildings in Berlin during the Gründerzeit period.
Moving into the 20th century, one of the most well-known individuals with the surname Zahn was Ernst Zahn (1867-1952), a German engineer and industrialist who played a significant role in the development of the automotive industry. He co-founded the Zahn-Werke company, which produced transmissions and other components for vehicles.
These examples highlight the longstanding presence of the surname Zahn within German history and its association with various professions and fields of expertise.
Demographics
Among Census respondents with the surname Zahn, the largest self-reported group is White at 90.8%. The next largest groups are Hispanic (3.9%) and Two or More Races (2.8%).
The bar chart below shows how Zahn 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 Zahn 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.
