Origin
The surname KROPP is of German origin, with its roots traced back to the 14th century. It is believed to have originated from the Lower Saxony region of northern Germany, where it was likely derived from the Middle Low German word "kropp," meaning "body" or "torso."
One of the earliest recorded instances of the KROPP name can be found in the Bremisches Urkundenbuch, a collection of historical documents from the city of Bremen, dated back to the year 1354. This reference suggests that the name may have initially referred to a person's physical stature or build.
During the 16th and 17th centuries, the KROPP surname spread across various parts of Germany, including areas such as Mecklenburg, Pomerania, and Brandenburg. This expansion can be attributed to the migration patterns of the time, as well as the increasing popularity of hereditary surnames.
Notable individuals bearing the KROPP surname include Johann Heinrich Kropp (1678-1748), a German theologian and author from Mecklenburg-Schwerin, and Karl Kropp (1799-1876), a Prussian architect and urban planner who contributed to the development of several cities in Germany.
In the 19th century, the KROPP name also found its way to the United States through German immigration. One early example is Johannes Kropp (1819-1890), a German immigrant who settled in Ohio and became a prominent farmer and community leader.
Another significant figure with the KROPP surname was Carl August Kropp (1867-1944), a German-American artist and illustrator known for his work in magazines and children's books. He was born in Germany but spent much of his career in the United States.
Additionally, the KROPP name has been associated with various place names throughout Germany, such as Kroppenstedt, a town in Saxony-Anhalt, and Kroppach, a municipality in Rhineland-Palatinate. These place names may have influenced the spelling variations of the surname over time.
While the KROPP surname has its roots in Germany, it has since been embraced by individuals of diverse backgrounds and nationalities, reflecting the global migration patterns and cultural exchanges that have shaped the modern world.
Demographics
Among Census respondents with the surname Kropp, the largest self-reported group is White at 92.7%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.5%).
The bar chart below shows how Kropp 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 Kropp 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 Kropp (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.
