Origin
Meaning and origin of Stadum
The surname Stadum is believed to have originated in Norway, with its roots dating back to the 11th century. It is thought to be derived from the Old Norse word "stod," which means a herd of horses or a stud farm. The name may have initially been used as a descriptive term for someone who worked with horses or lived near a stud farm.
One of the earliest recorded mentions of the name Stadum can be found in the Diplomatarium Norvegicum, a collection of medieval Norwegian documents. In a charter dated 1304, a man named Thorkel Stadum is mentioned as a witness to a land transaction in the region of Viken, which is now part of modern-day Oslo.
During the 13th and 14th centuries, the name Stadum appears to have been concentrated in the eastern regions of Norway, particularly in the areas around Oslo and Akershus. It is possible that the name was associated with specific places or farms, as was common with many Norwegian surnames during that time.
In the 16th century, a prominent individual named Hans Stadum (1525-1587) served as a Lutheran minister and played a significant role in the Reformation in Norway. He was known for his efforts in translating religious texts into the Norwegian language and promoting education among the common people.
Another notable figure with the surname Stadum was Peder Stadum (1639-1701), a Norwegian military officer who participated in the Scanian War between Denmark-Norway and Sweden. He rose to the rank of colonel and was awarded the title of nobleman for his service.
In the 19th century, a Norwegian explorer and naturalist named Baltazar Mathias Keilhau Stadum (1797-1858) gained recognition for his contributions to the study of geology and paleontology. He conducted extensive research in the Scandinavian regions and published several influential works on the subject.
While the surname Stadum is not among the most common in Norway today, it has a rich history and connections to various aspects of Norwegian culture, from agriculture and religion to military service and scientific exploration.

The bar chart below shows how Stadum 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 Stadum surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
