Origin
The surname Larsen is of Danish origin and is a patronymic name, derived from the personal name Lars. Lars itself is a Scandinavian form of the name Laurentius, which is derived from the Latin name Laurentius, meaning "from Laurentum" or "man from Laurentum". Laurentum was an ancient city in Italy, located near the modern-day town of Tor Pignattara.
The name Larsen first appeared in Denmark during the Middle Ages, when patronymic surnames became common. It indicated that the bearer was the son of a man named Lars. The earliest recorded instances of the name can be found in Danish parish records from the 16th and 17th centuries.
One notable historical figure with the surname Larsen was Hans Larsen Mink (1533-1593), a Danish admiral and naval hero who fought against the Swedish navy during the Northern Seven Years' War. He is credited with winning several crucial battles and preventing a Swedish invasion of Denmark.
Another prominent Larsen was Jacob Larsen (1828-1918), a Norwegian-American artist who is considered one of the most influential painters of the Golden Age of American landscape painting. His works, such as "The White Mountains" and "Autumn in New England", are highly regarded for their accurate depictions of the American wilderness.
In the literary world, Karen Larsen (1899-1988) was a Danish author and playwright known for her novels and short stories that explored themes of feminism and social issues. Her works, including "The Staircase" and "The Burning Bush", were widely acclaimed and translated into several languages.
Jens Larsen (1902-1988) was a Danish architect who played a significant role in the development of functionalist architecture in Denmark. He designed several notable buildings, including the Bellahøj Housing Estate in Copenhagen, which is considered a masterpiece of Danish functionalist architecture.
Knud Larsen (1865-1922) was a Danish explorer and naval officer who led several expeditions to Greenland and the Arctic regions. He is best known for his successful mapping and exploration of the northeast coast of Greenland, which was previously uncharted territory.
Demographics
Among Census respondents with the surname Larsen, the largest self-reported group is White at 91.0%. The next largest groups are Hispanic (3.6%) and Two or More Races (3.3%).
The bar chart below shows how Larsen 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 Larsen surname at the time of the 2020 Census, not any inherent property of the name itself.
