Origin
The surname Peterson has its origins in Scandinavia, particularly in Sweden and Norway. It is a patronymic surname, meaning that it is derived from the given name of the father or an ancestor. In this case, Peterson is derived from the personal name Peter, which comes from the Greek word "petros," meaning "rock."
The earliest recorded instances of the Peterson surname date back to the 13th century in various regions of Scandinavia. One of the earliest known bearers of the name was Petrus Petersson, a Swedish priest who lived in the late 13th century. Another early example is Jon Petersson, a Norwegian farmer mentioned in a land record from the year 1340.
As the surname spread across Scandinavia, it underwent various spelling variations, such as Pedersson, Pedersson, and Pederzen. These variations reflect the regional dialects and linguistic variations within the region.
In the 16th century, the Peterson surname began to appear in records outside of Scandinavia, particularly in areas with strong trade links or settlements from Scandinavian countries. One notable example is Hans Peterson, a Danish explorer who accompanied the explorer John Davis on his voyage to the Arctic in 1585.
Throughout history, there have been several notable individuals with the surname Peterson. Henrik Petersen (1568-1646) was a Danish astronomer and mathematician who made significant contributions to the field of celestial mechanics. Another notable figure was Anna Petterson (1623-1688), a Swedish woman who was accused of witchcraft during the infamous Torsåker witch trials.
In the 19th century, the Peterson surname gained prominence in the United States due to the influx of Scandinavian immigrants. One notable American bearer of the name was Peter Peterson (1825-1899), a Danish-American businessman and politician who served as the 12th Governor of Utah Territory.
Another significant figure was Frederik Petersen (1839-1912), a Danish-American artist known for his landscape paintings depicting the American West. His works are held in notable collections, including the Smithsonian American Art Museum.
Lastly, Gustav Petersen (1865-1939) was a Norwegian-American engineer and inventor who is credited with developing the first commercially successful gasoline-electric hybrid vehicle, the Petersen Hybrid, in the early 20th century.
These are just a few examples of the rich history and diverse individuals who have borne the surname Peterson throughout the centuries, reflecting its Scandinavian origins and its global spread over time.
Demographics
Among Census respondents with the surname Peterson, the largest self-reported group is White at 81.9%. The next largest groups are Black (9.7%) and Two or More Races (3.5%).
The bar chart below shows how Peterson 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 Peterson 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.
