Origin
The surname Cordsen is believed to have originated in Germany, specifically in the northern regions of the country. It likely emerged during the late Middle Ages or early Renaissance period, around the 15th or 16th centuries.
The name Cordsen is thought to be derived from the Old German word "kord," which means "cord" or "rope." This suggests that the name may have been initially associated with individuals who worked with ropes or cords, such as rope makers or sailors.
In the 16th century, there are records of a family named Cordsen living in the town of Lübeck, a prominent Hanseatic city in northern Germany. This indicates that the name had already established itself in the region by that time.
One of the earliest recorded individuals with the surname Cordsen was Hans Cordsen, born in 1562 in Lübeck. He was a merchant and trader who played a significant role in the city's commercial activities during the late 16th century.
Another notable figure was Anna Cordsen, born in 1612 in the town of Wismar, which was part of the Duchy of Mecklenburg at the time. Anna Cordsen was a prominent figure in the local community and is mentioned in several historical documents related to land disputes and legal proceedings.
In the 18th century, the Cordsen surname appeared in the records of the city of Hamburg. Johann Cordsen, born in 1723, was a respected shipbuilder who contributed to the city's maritime industry during that era.
During the 19th century, the Cordsen name spread to other parts of Germany, as well as neighboring countries like Denmark and Sweden. One notable individual was Karl Cordsen, born in 1837 in Schleswig-Holstein, who became a renowned linguist and scholar of Scandinavian languages.
Another prominent figure was Theodor Cordsen, born in 1853 in Hamburg. He was a successful businessman and philanthropist who founded several charitable organizations and supported educational initiatives in the city.
While the surname Cordsen is not among the most common names in Germany, it has a rich history spanning several centuries and has been associated with individuals from various walks of life, including merchants, artisans, scholars, and entrepreneurs.
Demographics
Among Census respondents with the surname Cordsen, the largest self-reported group is White at 87.9%. The next largest groups are Hispanic (3.7%) and Asian/Pacific Islander (3.7%).
The bar chart below shows how Cordsen 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 Cordsen 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.
