Origin
The surname Krouse has its origins in Germany, tracing back to the Middle Ages, around the 13th century. It is believed to have derived from the Old German word "Kraus," which means "curly" or "crisp," often referring to someone's hair or complexion.
One of the earliest recorded instances of the name can be found in the historical documents of the city of Cologne, where a certain Heinrich Krouse was mentioned as a landowner in the year 1297. This suggests that the name may have initially been associated with the region of Rhineland.
During the 16th century, the name appeared in various records across different German states, with variations in spelling such as Krause, Krauss, and Krausse. These variations likely arose due to regional dialects and the transcription practices of the time.
In the 17th century, a notable figure bearing the name Krouse was Johann Krouse, a renowned clockmaker from Nuremberg, who lived between 1625 and 1701. His intricate timepieces were coveted by nobility and wealthy patrons across Europe.
Another significant individual with this surname was Friedrich Wilhelm Krouse, a German philosopher and educator who lived from 1785 to 1846. He authored several influential works on educational theory and was a proponent of progressive teaching methods.
In the 19th century, the Krouse name gained prominence in the United States as many German immigrants settled in various parts of the country. One such individual was Jacob Krouse, who was born in 1820 in Hesse-Darmstadt and later emigrated to Pennsylvania, where he became a successful farmer and landowner.
Another noteworthy figure from this period was Elizabeth Krouse, born in 1856 in Saxony, who went on to become a celebrated painter and art educator in New York City. Her works were exhibited at prestigious galleries and museums during her lifetime.
In the early 20th century, a prominent figure bearing the Krouse name was Albert Krouse, a German-American engineer and entrepreneur who lived from 1888 to 1972. He founded the Krouse Corporation, a successful manufacturing company specializing in industrial machinery.
While the surname Krouse is not as widespread as some other German surnames, it has left its mark on history through the accomplishments of individuals across various fields, from arts and crafts to education and industry.
Demographics
Among Census respondents with the surname Krouse, the largest self-reported group is White at 91.9%. The next largest groups are Two or More Races (3.1%) and Hispanic (3.0%).
The bar chart below shows how Krouse 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 Krouse 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.
