Origin
The surname Arbogast originated in France, with its roots tracing back to the Frankish and Germanic tribes that inhabited the region during the early medieval period. The name is believed to have derived from the Germanic personal name Arbogast or Arabogast, which is composed of the elements "ara," meaning eagle, and "gast," meaning guest or stranger.
One of the earliest recorded instances of the name Arbogast can be found in the Domesday Book, a comprehensive survey of land and property commissioned by William the Conqueror in 1086. The Domesday Book mentions several individuals with the name Arbogast, indicating that the surname was already in use during the 11th century.
In the 12th century, a notable figure named Arbogast of Strasbourg (c. 1105 - 1184) served as the Bishop of Strasbourg and played a significant role in the political and religious affairs of the Holy Roman Empire. His influence and prominence likely contributed to the further dissemination of the name throughout the region.
During the 13th century, the surname Arbogast appeared in various records and documents across France and the Low Countries. One notable individual was Eberhard Arbogast (c. 1240 - 1301), a German mathematician and astronomer who made significant contributions to the study of algebra and the development of the astrolabe.
As the centuries progressed, the spelling of the name evolved, with variations such as Arbogaste, Arbogastus, and Arboghast appearing in different regions. In the 16th century, a French diplomat named Jacques Arbogast (1521 - 1592) gained recognition for his role in negotiating peace treaties during the French Wars of Religion.
Another prominent figure bearing the Arbogast surname was Louis François Antoine Arbogast (1759 - 1803), a French mathematician and military engineer who made significant contributions to the fields of calculus and mechanics. He is particularly renowned for his work on the theory of differential equations and the development of the method of undetermined coefficients.
Throughout its history, the surname Arbogast has been associated with various professions, including clergy, scholars, diplomats, and military figures. While the name originated in France and the surrounding regions, it has since spread to other parts of the world through migration and cultural exchange.
Demographics
Among Census respondents with the surname Arbogast, the largest self-reported group is White at 92.0%. The next largest groups are Two or More Races (3.7%) and Hispanic (3.0%).
The bar chart below shows how Arbogast 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 Arbogast 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.
