Origin
The surname Kunz originated in the Germanic regions of Europe, with roots dating back to the Middle Ages. It is a variant of the name Conrad, derived from the Old German words "kuon" (brave) and "rat" (counsel), implying a person of courageous wisdom. The name was initially spelled as Kuntz, Kunz, or Kunze, with regional variations across Germany, Switzerland, and Austria.
One of the earliest recorded instances of the name Kunz appears in the Codex Traditionum Monasterii Sancti Emmerammi, a medieval manuscript from the Benedictine monastery of St. Emmeram in Regensburg, Germany, dating back to the 11th century. The document mentions a certain "Chunradus dictus Chunz" (Conrad called Kunz) who made a land donation to the monastery.
In the 13th century, a notable bearer of the name was Kunz von Kauffungen, a German knight and ministerialis (unfree knight in service to a secular or ecclesiastical lord) who participated in the Crusades and is mentioned in the chronicles of the Teutonic Knights.
Another historical figure was Kunz von der Rosen, a 14th-century German poet and Minnesinger (a tradition of German love poetry) from the region of Thuringia. His poems and songs were widely circulated and appreciated in his time.
In the 15th century, a prominent bearer of the name was Kunz von Kaufungen, a German nobleman and military leader who served as a commander during the Hussite Wars against the followers of Jan Hus in Bohemia.
During the 16th century, the name Kunz was associated with the humanist scholar and playwright Konrad Kunz (1460-1534), who taught at the University of Vienna and authored several Latin plays and works on grammar.
Throughout history, the surname Kunz has been linked with various place names, such as Kunzendorf (a village in Saxony, Germany), Kunzelsau (a town in Baden-Württemberg, Germany), and Kunzweiler (a municipality in Rhineland-Palatinate, Germany), reflecting the geographical spread and establishment of families bearing this name.
Demographics
Among Census respondents with the surname Kunz, the largest self-reported group is White at 92.3%. The next largest groups are Hispanic (3.6%) and Two or More Races (2.6%).
The bar chart below shows how Kunz 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 Kunz surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Kunz (2000, 2010, 2020).
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.
