Origin
The surname Seversen is of Danish origin, with roots dating back to the 16th century. It is believed to have originated in the region of Jutland, which was historically a part of Denmark. The name is derived from the Old Danish word "sever," which means "south," combined with the patronymic suffix "-sen," indicating "son of."
One of the earliest recorded instances of the Seversen name can be found in the Danish Census of 1589, where a man named Hans Seversen was listed as a resident of the town of Ribe. This record suggests that the name was already in use during the late 16th century.
In the 17th century, the Seversen name appeared in various church records and parish registers throughout Denmark. Notable individuals from this period include Peder Seversen (1622-1690), a renowned Lutheran minister who served in the parish of Aalborg, and Niels Seversen (1649-1718), a skilled woodcarver whose intricate works adorned several churches in northern Jutland.
As the centuries progressed, the Seversen family spread across Denmark and beyond. In the late 18th century, a man named Jens Seversen (1768-1842) emigrated from Denmark to Norway, where he established a successful fishing business in the coastal town of Kristiansund. His descendants continued to carry the Seversen name throughout Norway.
Another notable bearer of the Seversen name was Johanne Seversen (1845-1923), a Danish educator and women's rights activist. She founded one of the first schools for girls in Copenhagen and played a pivotal role in the early feminist movement in Denmark.
In the 20th century, the name Seversen gained recognition through the achievements of Danish architect Hans Seversen (1910-1987), whose modernist designs left a lasting impact on the architectural landscape of Copenhagen and other Danish cities.
While the Seversen surname originated in Denmark, it has since spread to other parts of the world, particularly in countries with strong Danish heritage or immigration patterns. However, its roots can be traced back to the coastal regions of Jutland, where it first emerged as a distinct family name several centuries ago.
Demographics
Among Census respondents with the surname Seversen, the largest self-reported group is White at 88.7%. The next largest groups are Two or More Races (6.2%) and Hispanic (2.1%).
The bar chart below shows how Seversen 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 Seversen 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.
