Origin
The surname Diller is of German origin, derived from the Middle High German word "tille" meaning "dill" or "fennel". It likely originated as an occupational name for a grower or seller of dill or fennel in the medieval period.
The name first appeared in records from the 13th century in the regions of Bavaria and Swabia in southern Germany. Early variations of the spelling included Diller, Dillher, and Dillner. The name was also found in some areas of Switzerland during this time.
One of the earliest recorded references to the name is in the town records of Nürnberg, Germany, which mention a Johann Diller in 1349. Another early record is from the town of Ulm in 1402, which lists a Hans Diller as a resident.
In the 16th century, the name spread to other parts of Germany, as well as to neighboring regions such as Austria and parts of Eastern Europe. A notable bearer of the name from this period was the German botanist Johann Jakob Dillenius (1687-1747), who made significant contributions to the study of mosses and ferns.
During the 17th and 18th centuries, the name became more widespread across Europe, with bearers found in countries like France, Switzerland, and Poland. One famous bearer from this time was the German composer Johann Friedrich Dillermann (1739-1809), who composed operas and other works.
In the 19th century, the name began to appear in North America, as German immigrants brought the name with them to the United States and Canada. One notable American bearer was the businessman and philanthropist Clarence Diller (1840-1901), who made his fortune in the lumber industry and founded Diller College in Pennsylvania.
Other notable bearers of the Diller surname throughout history include the German painter Hans Diller (1599-1647), the Swiss painter Johann Jakob Diller (1784-1862), and the Austrian philosopher and writer Theodor Diller (1877-1954).
Demographics
Among Census respondents with the surname Diller, the largest self-reported group is White at 92.7%. The next largest groups are Hispanic (3.4%) and Two or More Races (2.2%).
The bar chart below shows how Diller 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 Diller 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.
