Origin
The surname Sibert originated in France during the Middle Ages.

This name was particularly popular among the Franks, a Germanic tribe that settled in modern-day France and the Low Countries.
One of the earliest recorded instances of the name Sibert can be found in the Domesday Book, a comprehensive survey of land ownership in England commissioned by William the Conqueror in 1086. The Domesday Book mentions a landowner named Sibert in the county of Hertfordshire.
In the 12th century, a nobleman named Sibert de Gand was a prominent figure in the court of King Henry II of England. He served as a royal chamberlain and was granted lands in Lincolnshire for his loyal service.
During the 13th century, a Franciscan friar named Sibert de Beka gained recognition for his theological writings and his work as a chronicler of events in his native Netherlands. He was born around 1200 and spent much of his life in the town of Deventer.
In the 15th century, a French nobleman named Sibert de La Tour d'Auvergne played a significant role in the Hundred Years' War between England and France. He was a skilled military commander and earned the title of Marshal of France for his service to King Charles VII.
Another notable figure with the surname Sibert was the German painter and printmaker Sibert van der Pluym, who lived in the 16th century. He was known for his intricate engravings and his involvement in the Nuremberg Renaissance art scene.
Throughout history, the surname Sibert has also been associated with various place names, such as Sibert in the department of Marne, France, and Sibert in the province of Liège, Belgium. These locations may have influenced the spelling and pronunciation of the name in different regions.
Demographics
Among Census respondents with the surname Sibert, the largest self-reported group is White at 72.3%. The next largest groups are Black (20.4%) and Two or More Races (3.4%).
The bar chart below shows how Sibert 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 Sibert 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.
