Origin
The surname OBERSON originated in Switzerland and is believed to have first appeared in the early 13th century. It is derived from the Swiss-German word "Ober," meaning "upper" or "higher," and likely referred to someone who lived in an elevated or upland area.
One of the earliest known references to the name can be found in the Swiss cantonal records of Vaud, where an individual named Johannes Oberson is mentioned in a document dated 1276. This suggests that the name was already well-established in the region by that time.
In the 14th century, the name appears in various Swiss municipal records and tax rolls, including those of Bern and Zurich. For example, a Petrus Oberson is listed as a landowner in the village of Interlaken in 1342.
As the OBERSON family spread throughout Switzerland and neighboring regions, the name underwent some slight variations in spelling, such as Obermann, Obermann, and Oberhausen. These variations often reflected local dialects and scribal preferences.
One notable bearer of the OBERSON name was Hans Oberson, a Swiss mercenary who fought in the Burgundian Wars of the late 15th century. He is believed to have been born in the village of Grindelwald around 1450.
Another prominent figure was the Swiss theologian and reformer Ulrich Oberson (1487-1551), who played a significant role in the Protestant Reformation in Switzerland. He was a contemporary and colleague of Martin Luther and Huldrych Zwingli.
In the 17th century, the OBERSON surname appears in records from the Swiss canton of Neuchâtel, where a family of that name owned a prominent vineyard in the village of Cressier. The vineyard was known as the "Domaine Oberson" and remained in the family's possession for several generations.
One of the earliest documented instances of the OBERSON name in North America can be found in the records of the French and Indian War, where a Swiss soldier named Jacob Oberson is listed as having served in the British colonial forces in the 1750s.
Throughout the centuries, the OBERSON surname has been associated with various notable individuals, including the Swiss writer and poet Emilie Oberson (1835-1894), the French painter and sculptor Gustave Oberson (1878-1941), and the Swiss architect and designer Max Oberson (1905-1985).
Demographics
Among Census respondents with the surname Oberson, the largest self-reported group is White at 79.6%. The next largest groups are Hispanic (9.2%) and Black (6.3%).
The bar chart below shows how Oberson 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 Oberson 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.
