Origin
The surname Kuhn originated in Germany, where it first appeared around the 12th century. It is derived from the German word "kühn," meaning "bold" or "brave." This suggests that the name may have been given to someone who displayed such qualities.
The earliest recorded instances of the name come from various regions of Germany, including Bavaria, Württemberg, and Saxony. In medieval times, the name was often spelled as "Kühn" or "Kuhn," reflecting the regional variations in pronunciation and spelling.
One of the earliest known references to the name can be found in the Codex Traditionum Monasterii Sancti Petri Salisburgensis, a 12th-century manuscript from the Benedictine monastery of St. Peter in Salzburg. This document mentions a person named "Chunradus Kuhn" in the year 1186.
Another notable historical figure bearing this surname was Johann Kuhn (1587-1668), a German composer and organist who served at the court of the Elector of Saxony. He is considered one of the most important composers of the early Baroque period in Germany.
In the 18th century, Johann Nepomuk Kuhn (1702-1784) was a renowned Bavarian sculptor and wood carver. His intricate works can be found in various churches and monasteries throughout Bavaria.
The name Kuhn has also been linked to various place names in Germany, such as Kuhnhausen, a village in Thuringia, and Kuhnsdorf, a town in Saxony-Anhalt. These place names likely derived from the surname itself, further reinforcing its historical roots in the region.
Another noteworthy figure was the philosopher and physicist Thomas Kuhn (1922-1996), known for his influential work "The Structure of Scientific Revolutions." He challenged the traditional view of scientific progress and introduced the concept of "paradigm shifts."
Lastly, the Kuhn family has produced several notable individuals throughout history, including the American baseball player Rick Kuhn (1946-2018), who played for the Chicago White Sox and the Detroit Tigers in the 1970s.
Demographics
Among Census respondents with the surname Kuhn, the largest self-reported group is White at 92.3%. The next largest groups are Hispanic (3.2%) and Two or More Races (2.8%).
The bar chart below shows how Kuhn 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 Kuhn 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.
