Origin
The surname MUELKEN originates from the German-speaking regions of Europe, with its roots tracing back to the early medieval period, around the 10th to 12th centuries. This name is believed to have derived from a Germanic word, "muolchen," which referred to a small stream or brook, suggesting that the earliest bearers of this surname may have lived near or owned lands adjacent to such a water source.
One of the earliest recorded instances of the MUELKEN name can be found in the "Codex Diplomaticus Saxoniae Regiae," a collection of historical documents from the Saxon region of Germany, dating back to the 13th century. This record mentions a certain "Henricus de Muelken" in the year 1275, indicating the presence of this surname in the region during that period.
Over the centuries, the MUELKEN name has undergone various spelling variations, such as Muelken, Mülken, Muhlken, and Mühlen, reflecting the regional dialects and scribal practices of different regions. These variations were often influenced by the local pronunciation and spelling conventions of the areas where the bearers of this name resided.
Notable individuals with the MUELKEN surname include Johann Wilhelm Muelken (1683-1746), a German composer and organist who served at the Marienkirche in Lübeck during the early 18th century. Another notable figure was Friedrich Muelken (1792-1864), a German landscape painter known for his depictions of the picturesque regions of Saxony and the Harz Mountains.
In the 16th century, records show a certain Hans Muelken (1520-1589) who was a prominent merchant and alderman in the city of Nuremberg, playing an influential role in the local trade and governance of the city during that time.
Moving forward in history, the Muelken name also appears in connection with geographical locations. For instance, the village of Mülken, located in the district of Vorpommern-Rügen in Mecklenburg-Vorpommern, Germany, likely derives its name from the MUELKEN surname, suggesting the presence of this family in the area during the naming of the settlement.
Another noteworthy individual was Emilie Muelken (1826-1895), a German novelist and writer who was born in Potsdam and authored several popular works of fiction during the 19th century, contributing to the literary landscape of her time.
While these are just a few examples, the MUELKEN surname has a rich history spanning centuries, originating from the German-speaking regions of Europe and leaving its mark on various aspects of society, from music and art to commerce and literature.
Demographics
Among Census respondents with the surname Muelken, the largest self-reported group is White at 96.3%. The next largest groups are Hispanic (0.9%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Muelken 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 Muelken 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.
