Origin
The surname Baudoux originates from the French region of Normandy in the late 11th century. It is derived from the Old French words "baud" meaning brave or bold, and "ou" meaning someone who embodies those qualities. The name likely evolved from a nickname given to a courageous individual.
One of the earliest recorded instances of the Baudoux name can be found in the Domesday Book, a manuscript compiled in 1086 by order of William the Conqueror. The entry refers to a landowner named Baudouin in the county of Hampshire, which is believed to be an early variation of the Baudoux surname.
In the 13th century, the Baudoux name appeared in various records across Normandy and the surrounding regions. Notable individuals from this time period include Jehan Baudoux, a merchant from the city of Rouen, mentioned in a trade document dated 1278.
During the 14th century, the name Baudoux spread across France and into neighboring countries. Geoffroy Baudoux, a French soldier, was recorded as participating in the Hundred Years' War against England in the 1340s.
In the 16th century, the Baudoux family gained prominence in the region of Picardy, located in northern France. Pierre Baudoux, born in 1512, was a renowned jurist and author of several legal treatises.
Moving into the 17th century, the Baudoux name can be found in various parts of Europe. Michel Baudoux, a Flemish painter born in 1589, was known for his religious artworks commissioned by churches and monasteries in the Low Countries.
As the centuries progressed, the Baudoux surname continued to appear across Europe and eventually made its way to other parts of the world through migration and colonization. Some notable figures include Jean-Baptiste Baudoux, a French botanist born in 1756, who made significant contributions to the study of plant life in the Caribbean.
Demographics
Among Census respondents with the surname Baudoux, the largest self-reported group is White at 97.3%. The next largest groups are Two or More Races (1.8%) and Hispanic (0.9%).
The bar chart below shows how Baudoux 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 Baudoux surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Baudoux (2000, 2010, 2020).
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.
