Origin
The surname Lumpp has its origins in Germany, with records dating back to the 16th century. It is believed to have derived from the Old German word "lump," meaning a clumsy or awkward person. The earliest known examples of the name can be found in various German parish records from the late 1500s, with spellings such as Lump, Lumpp, and Lümpp.
In the 17th century, the name appears in several town chronicles and municipal records across various regions of Germany, including Bavaria, Saxony, and Württemberg. One notable mention is in the 1632 census of the town of Esslingen, where a family by the name of Lumpp is listed among the residents.
The first recorded individual with the surname Lumpp is Hans Lumpp, born around 1550 in the village of Reutlingen, Württemberg. He was a farmer and landowner, and his descendants continued to reside in the area for several generations.
Another prominent figure was Johann Lumpp, a Protestant theologian and scholar born in 1665 in Nuremberg. He authored several influential works on theology and biblical interpretation and served as a professor at the University of Altdorf.
During the 18th century, the name Lumpp began to spread beyond Germany, with several families emigrating to other parts of Europe and North America. One notable individual was Johann Georg Lumpp, born in 1725 in Württemberg, who later settled in Pennsylvania, United States, in the mid-1700s.
In the 19th century, the Lumpp surname gained further recognition with the birth of Karl Gottlob Lumpp in 1810 in Stuttgart, Germany. He was a renowned botanist and horticulturist, known for his contributions to the study of plant taxonomy and his extensive work on the flora of Württemberg.
Another noteworthy figure was Friedrich Lumpp, born in 1843 in Baden-Württemberg. He was a prominent architect and urban planner, responsible for the design of several iconic buildings and public spaces in cities across Germany and Switzerland.
While the surname Lumpp originated in Germany, it has since spread to other parts of the world, with descendants found in various countries, including the United States, Canada, Australia, and beyond.
Demographics
Among Census respondents with the surname Lumpp, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (4.0%) and Hispanic (2.5%).
The bar chart below shows how Lumpp 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 Lumpp 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.
