Origin
The surname Koltermann is of German origin, traced back to the late medieval period, specifically the 13th and 14th centuries. It is believed to have originated in the northern regions of Germany, particularly in the areas around the states of Lower Saxony and Schleswig-Holstein.
The name Koltermann is a compound word, derived from the Old German words "kolder" and "mann." "Kolder" is thought to have meant a small, undeveloped sprout or bud, while "mann" referred to a person or man. The combination of these two words suggests that the name Koltermann may have initially been used as a descriptive nickname for someone who was small in stature or perhaps a young man.
One of the earliest known records of the name Koltermann can be found in the Bremisches Urkundenbuch, a collection of historical documents from the city of Bremen, dating back to 1342. In this document, a person named Hinricus Koltermann is mentioned as a resident of the city.
Another early reference to the name comes from the Lübecker Oberstadtbuch, a civic registry from the city of Lübeck, where a Hermann Koltermann is recorded as a citizen in the year 1379.
During the 15th century, variations of the name, such as Koldermann and Koltersman, can be found in various records from the northern German regions, including the town of Stade in Lower Saxony.
One notable figure with the surname Koltermann was Johann Koltermann, a merchant and ship owner from the Hanseatic city of Hamburg, who lived in the late 16th century. He was involved in the lucrative salt trade and owned several ships that sailed to ports in the Baltic Sea and North Sea regions.
In the 17th century, a Lutheran pastor named Christoph Koltermann served in the town of Rostock, in the duchy of Mecklenburg-Schwerin. He was known for his scholarly writings and sermons during the tumultuous years of the Thirty Years' War.
The 18th century saw the emergence of a prominent Koltermann family in the city of Bremen. Gerhard Koltermann, born in 1712, was a successful merchant and shipowner, while his son, Johann Koltermann (1745-1823), became a respected lawyer and served as a judge in the city's court system.
In the 19th century, a German artist named Wilhelm Koltermann (1838-1903) gained recognition for his landscape paintings, particularly those depicting scenes from the coastal regions of northern Germany.
Demographics
Among Census respondents with the surname Koltermann, the largest self-reported group is White at 90.9%. The next largest groups are Hispanic (8.3%) and American Indian/Alaska Native (0.8%).
The bar chart below shows how Koltermann 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 Koltermann 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.
