Origin
The surname Knutson is of Scandinavian origin, specifically from Norway and Sweden. It is a patronymic name, meaning it was derived from the given name of the father or an ancestor. Knutson is believed to have originated in the late medieval period, sometime around the 13th or 14th century.
In its earliest form, the name was likely spelled as Knutsson or Knutsen, reflecting the Old Norse and Swedish spelling conventions. It is derived from the Old Norse personal name Knutr, which means "knot" or "knot of wood." This name was commonly used in Scandinavia during the Viking Age and the Middle Ages.
The Knutson surname is believed to have first emerged in coastal regions of Norway and Sweden, where many families were involved in maritime activities and fishing. The name may have referred to someone who was skilled in knot-tying or worked with ropes and rigging.
One of the earliest recorded instances of the name Knutson can be found in the Swedish census records from the late 16th century. In these records, several individuals with the surname Knutson are mentioned, indicating that the name had already been established by that time.
Throughout history, there have been several notable individuals bearing the Knutson surname. One of the earliest was Knut Knutson (1390-1449), a Swedish nobleman and Lord of Valö. Another prominent figure was Knut Knutsson (1508-1568), a Swedish nobleman and military commander who served as a regent during the minority of King Eric XIV.
Other notable individuals with the Knutson surname include Hans Knutson (1767-1846), a Norwegian merchant and ship owner; Nils Knutson (1880-1955), a Norwegian-American farmer and politician; and Lily Knutson (1886-1979), a Swedish-American artist and illustrator.
The Knutson surname has since spread beyond Scandinavia, with many individuals of Norwegian, Swedish, and Danish descent carrying the name in various parts of the world, particularly in North America and other regions with significant Scandinavian immigration.
Demographics
Among Census respondents with the surname Knutson, the largest self-reported group is White at 93.3%. The next largest groups are Two or More Races (2.7%) and Hispanic (2.4%).
The bar chart below shows how Knutson 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 Knutson surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Knutson (2000, 2010, 2020).
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.
