Origin
The surname Krupp is of German origin, dating back to the late Middle Ages. Its roots can be traced to the Lower Rhineland region of what is now western Germany, particularly around the areas of Essen and Duisburg.
One theory suggests that the name derives from the Middle Low German word "krupp" or "kropp," which referred to a hunchback or a person with a bent or crooked body. It may have originated as a descriptive nickname for an individual with such a physical characteristic.
Another possibility is that the name is related to the German word "Kröpfe," which means crests or tufts, potentially referring to a distinctive hairstyle or facial feature of an early bearer of the name.
The earliest known record of the Krupp name dates back to the 15th century, with a mention of a Heinrich Krupp in the city records of Essen in 1482. Over the following centuries, the name appeared in various historical documents in the region, such as parish registers, tax records, and guild rolls.
One of the most notable bearers of the Krupp name was Alfred Krupp (1812-1887), a German industrialist who founded the Krupp steel works in Essen. His company became one of the largest and most influential arms manufacturers in Europe, playing a significant role in the industrialization of Germany.
Another prominent figure was Friedrich Alfred Krupp (1854-1902), the grandson of Alfred Krupp, who inherited and greatly expanded the family business, making it a global industrial empire. He was also known for his philanthropy and the construction of workers' housing and social welfare facilities in Essen.
The Krupp name gained further recognition with Bertha Krupp (1886-1957), the daughter of Friedrich Alfred Krupp, who inherited and managed the family's vast industrial holdings during the early 20th century.
Gustav Krupp von Bohlen und Halbach (1870-1950), another member of the Krupp dynasty, was a German diplomat and industrialist who served as the chairman of the Krupp company during the interwar period and World War II.
In the realm of literature, the German writer and dramatist Marie von Ebner-Eschenbach (1830-1916) was born Marie Freifrau von Ebner-Eschenbach, with her maiden name being Krupp.
While the Krupp name has its roots in the medieval German region, it has since spread worldwide, with bearers found in various countries and communities. However, its historical significance remains closely tied to the influential Krupp family and their industrial legacy in Germany.
Demographics
Among Census respondents with the surname Krupp, the largest self-reported group is White at 94.3%. The next largest groups are Hispanic (2.5%) and Two or More Races (2.0%).
The bar chart below shows how Krupp 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 Krupp 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.
