Origin
The surname Kropf has its origins in Germany, with records dating back to the 16th century. It is believed to be derived from the Middle High German word "kropf," which means "bulge" or "swelling." This suggests that the name may have originally referred to a person with a noticeable physical characteristic, such as a large neck or swollen throat.
In the early days, the name was primarily concentrated in the regions of Bavaria and Württemberg in southern Germany. Variations in spelling were common, with forms like "Kropff," "Kröpf," and "Kröpfer" also appearing in historical records.
One of the earliest documented references to the name Kropf can be found in the Kirchenbücher (church records) of the town of Esslingen, near Stuttgart, in the year 1585. Here, a man named Hans Kropf is mentioned in relation to a baptismal record.
As the name spread across Germany and into neighboring regions, it became associated with several notable individuals. In the 17th century, Johann Kropf (1629-1695) was a prominent theologian and author from Nuremberg, whose works included commentaries on the Bible and treatises on church history.
In the 19th century, Franz Xaver Kropf (1836-1902) was an Austrian botanist and explorer who conducted extensive research in South Asia, particularly in the Himalayan region. His contributions to the study of flora and fauna in the region were significant.
Another notable bearer of the name was Friedrich Kropf (1846-1914), a German philologist and linguist who specialized in the study of Romani languages and culture. His work on documenting and preserving the Romani language and traditions was instrumental in advancing the understanding of this ethnic group.
In more recent times, the name Kropf has been associated with individuals such as Renate Kropf (born 1936), a German politician and member of the Social Democratic Party, who served as a member of the Bundestag (German parliament) from 1976 to 2002.
It is worth noting that while the name Kropf originated in Germany, it has since spread to other parts of Europe and even to North America through migration and immigration patterns.
Demographics
Among Census respondents with the surname Kropf, the largest self-reported group is White at 93.7%. The next largest groups are Hispanic (3.6%) and Two or More Races (1.6%).
The bar chart below shows how Kropf 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 Kropf 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.
