Origin
The surname Thoemke is of German origin, with its roots traced back to the 16th century in the regions of northern Germany and parts of modern-day Poland. It is believed to have derived from the Germanic word "thoem," which referred to a small gathering or assembly of people, potentially indicating that the name's earliest bearers lived in a hamlet or village.
One of the earliest recorded instances of the name Thoemke can be found in the Kirchenbücher (church records) of the town of Lauenburg in the former Duchy of Saxe-Lauenburg, dating back to the late 1500s. These records document the presence of families with the name Thoemke living in the area during that time period.
In the 17th century, the name appears in various historical documents from the region, such as tax records and land registers. For instance, a record from 1684 mentions a Johann Thoemke, a farmer from the village of Neustadt in the former Duchy of Pomerania.
As the centuries progressed, the Thoemke name spread across different parts of northern Germany and neighboring regions. Notable individuals bearing this surname include Johann Friedrich Thoemke (1762-1837), a German jurist and legal scholar from the town of Greifenberg in Pomerania, and Carl Thoemke (1825-1897), a banker and entrepreneur from the city of Rostock in Mecklenburg-Vorpommern.
Another prominent figure was Karl Thoemke (1859-1936), a German-American businessman and philanthropist who immigrated to the United States in the late 19th century and founded the Thoemke Brewing Company in Milwaukee, Wisconsin.
In the 20th century, one of the most renowned individuals with the Thoemke surname was Hans Thoemke (1907-1998), a German-born architect and urban planner who played a significant role in the reconstruction and development of several German cities after World War II.
While the name Thoemke is not among the most common surnames today, it continues to be found predominantly in northern Germany, as well as in communities with German ancestry in other parts of the world, such as the United States and Canada.
Demographics
Among Census respondents with the surname Thoemke, the largest self-reported group is White at 90.0%. The next largest groups are Two or More Races (5.4%) and Hispanic (3.1%).
The bar chart below shows how Thoemke 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 Thoemke 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.
