Origin
The surname Roser is of German origin, tracing its roots back to the Middle Ages. It is believed to have originated as an occupational name for someone who cultivated roses or worked with roses in some capacity. The name is derived from the Old German word "rose," meaning the flower.
One of the earliest recorded instances of the name Roser can be found in the Codex Diplomaticus Saxoniae Regiae, a collection of medieval documents from Saxony, dating back to the 13th century. In this record, a certain "Henricus Roser" is mentioned as a landowner in the region.
During the 14th century, the name Roser appeared in various records across Germany, particularly in the southern regions. In the town of Augsburg, there is a record of a family called "die Roseren," which translates to "the Rosers," indicating their profession was likely related to roses or rose cultivation.
In the 15th century, the name Roser was also found in the Bavarian town of Nuremberg, where a notable figure named Hans Roser (1494-1562) was a successful merchant and member of the town council. His legacy is still remembered in the city's historical records.
Another prominent individual with the surname Roser was Johann Roser (1608-1683), a German theologian and author from Saxony. He was known for his works on religious matters and his contributions to the Lutheran church.
During the 16th and 17th centuries, the name Roser was also present in various parts of Switzerland, particularly in the German-speaking regions. One notable example is the town of Roser, located in the canton of Graubünden, which likely derived its name from the presence of individuals with the surname Roser in the area.
In the 18th century, the name Roser was found in records from the Palatinate region of Germany, where a family of wine merchants and vintners carried the surname. One such individual was Johann Friedrich Roser (1738-1805), a renowned winemaker and vineyard owner in the town of Neustadt an der Weinstraße.
As people migrated from German-speaking regions to other parts of Europe and the Americas, the surname Roser spread to different countries. However, its origins can be traced back to the German lands, where it was closely associated with the cultivation and trade of roses.
Demographics
Among Census respondents with the surname Roser, the largest self-reported group is White at 92.6%. The next largest groups are Hispanic (3.4%) and Two or More Races (2.2%).
The bar chart below shows how Roser 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 Roser 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.
