Origin
The surname Overby has its origins in the Scandinavian countries, particularly in Norway and Denmark. It is believed to have emerged around the 11th or 12th century as a locational name, referring to a place or settlement known as "Overby" or a similar variation.
One of the earliest recorded instances of the name Overby can be found in the Norwegian census records from the late 13th century, where it appears as "Ovrebi." This spelling suggests that the name may have originated from the Old Norse words "yfri" meaning "upper" and "by" meaning "village" or "settlement."
During the medieval period, the name Overby was predominantly concentrated in the coastal regions of Norway and Denmark. It is possible that some individuals bearing this surname may have been involved in maritime activities or fishing communities located near the upper villages or settlements.
In the 15th century, a notable figure named Hans Overby (c. 1420-1489) was a prominent merchant and ship owner based in the city of Bergen, Norway. His successful trading ventures and contributions to the local economy helped establish the Overby name as a respected mercantile family in the region.
Another historical reference to the name Overby can be found in the Danish chronicles from the 16th century, where a nobleman named Jørgen Overby (c. 1525-1592) is mentioned as a trusted advisor to King Frederik II. Overby's diplomatic skills and counsel were highly valued by the Danish monarch during his reign.
As the centuries progressed, the Overby surname spread beyond Scandinavia, with some families migrating to other parts of Europe and eventually to the Americas. One notable individual was Carl Overby (1789-1868), a Swedish-born explorer and adventurer who participated in several expeditions to the Arctic regions in the early 19th century.
Another prominent figure with the Overby surname was Kathrine Overby (1864-1935), a Norwegian-American educator and activist who played a significant role in establishing Norwegian-language schools and promoting cultural preservation among Norwegian immigrants in the United States.
The Overby name has also been associated with notable figures in the arts and literature. For example, Ingrid Overby (1908-1991) was a renowned Danish sculptor and ceramist whose works are exhibited in numerous galleries and museums around the world.
While the Overby surname may have evolved and spread across different regions over time, its origins can be traced back to the Viking-era settlements and coastal communities of Scandinavia, where it likely originated as a locational name describing an "upper village" or elevated settlement.
Demographics
Among Census respondents with the surname Overby, the largest self-reported group is White at 81.9%. The next largest groups are Black (11.7%) and Hispanic (2.8%).
The bar chart below shows how Overby 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 Overby 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.
