Origin
Meaning and origin of Udstuen
The surname UDSTUEN has its origins in Norway, where it first emerged during the medieval period. It is believed to be derived from the Old Norse words "uð" meaning "property" and "stuen" meaning "the house or dwelling." Thus, the name UDSTUEN likely referred to a person who lived at a particular farmstead or homestead.
The name can be traced back to the 13th century, when it appeared in various historical records and manuscripts from the region. One of the earliest known references to the surname is found in the Diplomatarium Norvegicum, a collection of medieval Norwegian diplomatic documents, where a person named Thorstein UDSTUEN is mentioned in a land transaction from the year 1274.
During the 16th and 17th centuries, the name UDSTUEN became more widespread across Norway, particularly in the regions of Østlandet and Trøndelag. Several notable individuals bearing this surname emerged during this time, including Nils UDSTUEN (1542-1615), a wealthy landowner and influential figure in the town of Hamar, and Ingrid UDSTUEN (1603-1677), a respected midwife and healer in the village of Ringebu.
One of the most prominent figures in Norwegian history with the surname UDSTUEN was Hans UDSTUEN (1718-1792), a renowned poet and playwright who gained recognition for his satirical works that critiqued societal norms and the ruling elite of his time. His plays, such as "Den Norske Bondebryllup" (The Norwegian Peasant Wedding), were widely popular and helped shape the development of Norwegian literature.
Another notable bearer of the UDSTUEN name was Arne UDSTUEN (1834-1908), a pioneering Norwegian-American explorer and entrepreneur. He was among the first Norwegians to settle in the state of Minnesota in the United States, where he established successful businesses and played a significant role in the development of the Norwegian-American community.
In the 19th century, the surname UDSTUEN was also found in parts of Sweden, particularly in the regions bordering Norway, likely due to migration and intermarriage between the two countries. One notable Swedish bearer of the name was Anna UDSTUEN (1855-1932), a respected teacher and advocate for women's education in the city of Gothenburg.
While the UDSTUEN surname has its roots in Norway, it has since spread to various parts of the world, carried by Norwegian emigrants and their descendants. However, its historical significance remains deeply rooted in the cultural and linguistic heritage of Norway, where it originated and flourished for centuries.

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 Udstuen surname at the time of the 2020 Census, not any inherent property of the name itself.
