Origin
Meaning and origin of Kopp
The surname Kopp is of German origin, with its roots dating back to the Middle Ages. It is believed to have derived from the German word "Kopf," which translates to "head" or "leader." This suggests that the name may have been initially given as a nickname to someone who was perceived as a leader or had a prominent head.
Historically, the name Kopp was most prevalent in the regions of Bavaria and Saxony in Germany. In the 14th century, records show a mention of a "Konrad Kopp" in the town of Nürnberg, suggesting the name's existence during that time.
One of the earliest known references to the surname Kopp can be found in the "Codex Diplomaticus Saxoniae," a collection of historical documents from Saxony, which mentions a "Heinrich Kopp" in the year 1376.
During the 16th century, the name Kopp appeared in various town records and church registers across Germany. Notable individuals bearing this surname include Johann Kopp (1523-1590), a German theologian and reformer, and Johann Kopp (1644-1724), a German jurist and scholar.
In the 17th century, the name Kopp was associated with several prominent figures, such as Johann Kopp (1617-1673), a German mathematician and astronomer, and Jakob Kopp (1634-1694), a German physician and chemist.
Moving into the 18th century, the name Kopp continued to be found in various records across Germany. One notable individual from this period was Johann Adam Kopp (1698-1772), a German painter and engraver.
As the Kopp family spread throughout Europe, variations in spelling and pronunciation emerged. In some regions, the name was recorded as Koppe or Kop, while in others, it was written as Kopp or Koppen.
While the surname Kopp has its origins in Germany, it has since been carried by individuals across the world, with descendants found in countries such as the United States, Canada, and Australia.
Demographics

The bar chart below shows how Kopp 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 Kopp 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 Kopp (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
