One of the earliest recorded instances of the surname Unger can be found in the town of Bruck an der Mur, located in the Austrian state of Styria. In the 14th century, a man named Ulrich Unger was mentioned in a document from 1348, indicating the presence of this surname in the region during that time period.
Another early record of the Unger name is found in the Codex Diplomaticus Brandenburgensis, a collection of historical documents from the Margraviate of Brandenburg, dating back to the 13th century. Here, a certain Johannes Unger is mentioned in a document from the year 1364.
Throughout the centuries, several notable individuals have borne the surname Unger. One prominent figure was Johann Friedrich Unger (1714-1781), a German jurist and professor of law at the University of Halle. Another was Johann Georg Unger (1715-1788), a German physician and botanist known for his work on plant taxonomy.
In the realm of literature, Theodor Unger (1806-1835) was a German poet and writer who is remembered for his contributions to the Biedermeier literary movement. Additionally, Carl Richard Unger (1836-1885) was a German historian and author who specialized in the study of ancient civilizations.
The Unger surname has also been associated with various places and geographical locations. For instance, the town of Unger in the German state of Saxony-Anhalt likely derived its name from the presence of individuals bearing this surname in the area.
Throughout history, the surname Unger has undergone various spelling variations, including Ungar, Ungher, and Unghern, reflecting the influence of different regional dialects and linguistic influences over time.
Demographics
Among Census respondents with the surname Unger, the largest self-reported group is White at 91.8%. The next largest groups are Hispanic (2.9%) and Two or More Races (2.5%).
The bar chart below shows how Unger 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 Unger 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.
