Origin
The surname Traulsen originates from northern Germany, particularly the regions of Schleswig-Holstein and Mecklenburg-Vorpommern. It is derived from the Old German words "trou" meaning faithful or true, and "lausen" which translates to listen or obey. The name likely emerged in the 13th or 14th century during the Middle Ages.
One of the earliest recorded mentions of the Traulsen name can be found in a church registry from the town of Lübeck in 1487, where a certain Hans Traulsen is listed as a member of the local guild of merchants. Another early reference appears in a land deed from 1523 in the village of Oldenburg, which bears the signature of a farmer named Claus Traulsen.
In the 16th century, the Traulsen name is associated with the Protestant Reformation movement in northern Germany. A notable figure was Martin Traulsen (1492-1568), a Lutheran minister and theologian who served as a pastor in the city of Rostock and was a close friend and ally of the reformer Martin Luther.
During the 17th and 18th centuries, the Traulsen name spread throughout the German states and principalities, with various branches emerging in cities like Hamburg, Bremen, and Lübeck. One prominent Traulsen was Johann Traulsen (1677-1744), a merchant and ship owner based in Hamburg who played a significant role in the city's maritime trade with the Netherlands and England.
The 19th century saw several Traulsens make their mark in various fields. Carl Traulsen (1809-1887) was a renowned architect from Mecklenburg who designed many notable buildings in Berlin and other German cities. His contemporary, Gustav Traulsen (1819-1892), was a respected linguist and philologist who published extensively on the Germanic languages.
In more recent times, notable individuals with the Traulsen surname include Hans Traulsen (1915-1998), a German naval officer and U-boat commander during World War II, and Inge Traulsen (1934-2004), a prominent East German actress and theater director who performed with the renowned Berliner Ensemble.
Demographics
Among Census respondents with the surname Traulsen, the largest self-reported group is White at 87.3%. The next largest groups are Hispanic (5.9%) and Two or More Races (3.4%).
The bar chart below shows how Traulsen 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 Traulsen 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.
