Origin
The surname Pedersen originates from Denmark and Norway, and it dates back to the early medieval period. It is a patronymic name, derived from the given name Peter, which itself comes from the Greek word "petros," meaning "rock." The suffix "-sen" indicates "son of," so Pedersen literally means "son of Peter."
One of the earliest recorded mentions of the name Pedersen appears in the Danish Census Book of 1890, where it is listed as one of the most common surnames in the country. This suggests that the name had already been in use for several centuries by that point.
In Norway, the name Pedersen can be traced back to the 13th century, when it was commonly found in the regions of Trøndelag and Møre og Romsdal. Some of the earliest recorded bearers of the name in Norway include Peder Magnusson Pedersen, a farmer who lived in the village of Holtan in the late 16th century, and Hans Pedersen, a merchant from Trondheim who was mentioned in a trade record from 1624.
During the Middle Ages, the name Pedersen was often associated with the clergy and the educated classes, as the name Peter was popular among Christians due to its biblical connections. One notable example is Peder Pedersen Plade (c. 1510-1585), a Danish theologian and reformer who played a significant role in the Protestant Reformation in Denmark.
Another notable figure bearing the surname Pedersen was Peder Griffenfeld (1635-1699), a Danish statesman and diplomat who served as the Chancellor of Denmark under King Christian V. He was involved in the Scandinavian branch of the Northern Wars and played a crucial role in the Treaty of Lund in 1679.
In the 19th century, the name Pedersen was associated with several prominent figures, including Jens Andreas Pedersen (1792-1857), a Norwegian philologist and lexicographer who is best known for his work on the Dano-Norwegian language, and Carl Pedersen (1854-1926), a Danish linguist and scholar of comparative linguistics.
While the surname Pedersen is most common in Denmark and Norway, it has also been found in other parts of Scandinavia, as well as in the United States and other countries where Scandinavian immigrants settled. Despite its widespread use, the name has retained its strong connection to its Danish and Norwegian origins throughout history.
Demographics
Among Census respondents with the surname Pedersen, the largest self-reported group is White at 91.4%. The next largest groups are Two or More Races (3.5%) and Hispanic (3.3%).
The bar chart below shows how Pedersen 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 Pedersen 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.
