Origin
The surname Andreasen originates from Denmark and its earliest known bearers lived in the 14th century. It is a patronymic name meaning "son of Andreas", with Andreas being the Scandinavian form of the Greek name Andreas, meaning "manly" or "brave". The name is derived from the Greek word "andros", meaning "man".
The earliest recorded instance of the name Andreasen can be found in the Danish Census Rolls of 1381, where a man named Peder Andreasen is listed as a resident of Copenhagen. It is likely that the name was initially used as a way to identify individuals by their father's name, a common practice in Scandinavian countries during the Middle Ages.
In the 16th century, the name Andreasen appeared in the records of the Danish town of Odense, where a family of merchants and traders bearing the surname were prominent members of the local community. One notable individual from this family was Hans Andreasen (1543-1612), a successful merchant and shipping magnate who played a significant role in the development of Odense's maritime trade.
During the 17th century, the name Andreasen spread beyond Denmark and into other parts of Scandinavia. In Sweden, a prominent bearer of the name was Carl Andreasen (1658-1722), a military officer who served in the Swedish army during the Great Northern War against Russia.
As the centuries passed, the Andreasen name continued to be carried by individuals from various walks of life. In the 19th century, one notable figure was the Danish painter and artist Nicolai Andreasen (1811-1883), known for his landscapes and depictions of rural life in Denmark.
Another significant bearer of the Andreasen name was Christian Andreasen (1870-1945), a Norwegian-American businessman and philanthropist who founded the Andreasen Shipping Company in San Francisco, California. His success in the shipping industry allowed him to become a prominent figure in the Norwegian-American community and a generous donor to various charitable causes.
In more recent times, the name Andreasen has been carried by several academics and scholars, including Niels-Erik Andreasen (1924-2005), a Danish-American professor of marketing and a pioneer in the field of consumer behavior research.
Overall, the surname Andreasen has a rich history rooted in Scandinavia, with its earliest bearers emerging in 14th-century Denmark. Throughout the centuries, the name has been associated with individuals from diverse backgrounds, including merchants, military personnel, artists, businessmen, and scholars.
Demographics
Among Census respondents with the surname Andreasen, the largest self-reported group is White at 91.8%. The next largest groups are Hispanic (3.4%) and Two or More Races (2.8%).
The bar chart below shows how Andreasen 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 Andreasen 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.
