Origin
The surname Karlson is of Swedish origin, first appearing in historical records from the 15th century. It is derived from the Old Norse name Karlr, meaning "freeman" or "free man," combined with the patronymic suffix "-son," indicating "son of."
One of the earliest recorded instances of the Karlson surname can be found in the Dano-Norwegian census records from the late 16th century, where it appears spelled as both "Karlson" and "Carlson." The name was particularly prevalent in the regions of Skåne and Halland, which were under Danish rule at the time.
In the 17th century, the Karlson name began to appear more frequently in Swedish church records, particularly in the provinces of Småland and Västergötland. One notable individual from this period was Johan Karlson, a Swedish military officer born in 1661, who served in the Great Northern War under King Charles XII.
During the 18th century, the Karlson surname continued to spread throughout Sweden, and several prominent individuals bore this name. Among them was Anders Karlson (1701-1779), a Swedish clergyman and author who served as the rector of the Linköping Cathedral School.
In the 19th century, the Karlson surname gained international recognition with the birth of Emil Karlson (1852-1926), a Swedish chemist and professor at the University of Uppsala. He is best known for his contributions to the study of organic chemistry and the development of the Karlson-Winkler method for determining the molecular weight of liquids.
Another notable figure from this era was Gustaf Karlson (1855-1927), a Swedish artist and painter whose works often depicted scenes from rural life in Sweden. His paintings are displayed in several museums across the country, including the Nationalmuseum in Stockholm.
As Swedish immigration to North America increased in the late 19th and early 20th centuries, the Karlson surname also found its way to the United States and Canada. One prominent individual from this period was Erik Karlson (1882-1953), a Swedish-American engineer and inventor who held numerous patents for his contributions to the development of the modern washing machine.
These examples illustrate the rich history and global reach of the Karlson surname, which has its roots in the ancient Nordic tradition but has since spread across the world, carried by individuals who have made significant contributions in various fields.
Demographics
Among Census respondents with the surname Karlson, the largest self-reported group is White at 90.6%. The next largest groups are Two or More Races (4.0%) and Hispanic (3.1%).
The bar chart below shows how Karlson 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 Karlson 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.
