Origin

Meaning and origin of Hansen

The surname Hansen is of Scandinavian origin, specifically from Denmark and Norway. It is a patronymic surname, meaning it originated from the name of the father or an ancestor. The name is derived from the old Norse personal name Hans, a shortened form of Johannes, which was the Scandinavian version of the name John.

In the Middle Ages, the use of surnames was not widespread, and people were often identified by their given name followed by their father's name with the suffix "-son" added. Hansen, meaning "son of Hans," was one such surname that emerged during this time.

The earliest recorded instances of the surname Hansen can be traced back to the 13th and 14th centuries in Danish and Norwegian records. One of the earliest known bearers of the name was Niels Hansen, a Danish nobleman who lived in the late 13th century.

As the use of surnames became more common, the name Hansen spread across Scandinavia and eventually to other parts of Europe and the Americas as people migrated. In some cases, the spelling of the name may have been modified slightly, such as Hanson or Hannsen, but the root remained the same.

Notable individuals with the surname Hansen throughout history include:

1. Peter Andreas Hansen (1795-1874), a Danish astronomer and mathematician known for his work on the orbit of the Moon and the theory of comets.

2. Gerhard Armauer Hansen (1841-1912), a Norwegian physician who discovered the bacterium responsible for leprosy, now known as Mycobacterium leprae.

3. Alvin Hansen (1887-1975), an American economist and professor at Harvard University, known for his contributions to the theory of the business cycle and Keynesian economics.

4. Lars Hansen (born 1952), an American economist and a recipient of the Nobel Memorial Prize in Economic Sciences in 2013 for his work on asset pricing and time series analysis.

5. Edvard Hansen (1888-1957), a Norwegian painter and printmaker, known for his landscapes and depictions of rural life in Norway.

The surname Hansen has a rich history and has been carried by individuals from various walks of life, including scientists, artists, and scholars, throughout the centuries.

Demographics

Ancestry and ethnicity for Hansen

Among Census respondents with the surname Hansen, the largest self-reported group is White at 91.3%. The next largest groups are Hispanic (3.6%) and Two or More Races (3.1%).

The bar chart below shows how Hansen 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 Hansen surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

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.

Why don't the ancestry percentages always add up to exactly 100%?

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.
