Origin
Meaning and origin of Dujon
The surname DUJON has its origins in France, dating back to the 16th century. It is believed to have derived from the French word "dujon," which referred to a small hill or hillock. This suggests that the name may have originally been a descriptive term for someone who lived on or near a small hill.
One of the earliest records of the DUJON surname can be found in the parish records of the village of Saint-Étienne-de-Montluc, located in the Loire-Atlantique region of western France. The name appears in a baptismal record from 1593, where a child named Jacques DUJON was christened.
In the 17th century, the DUJON name spread to other regions of France, including the Normandy and Brittany regions. It is possible that some bearers of the name may have been among the French settlers who immigrated to the Americas during this period, particularly to the French colonies in Canada and the Caribbean.
One notable individual with the DUJON surname was Jacques DUJON, a French painter and engraver who lived from 1640 to 1700. He was born in Paris and is known for his landscapes and religious works, some of which can still be found in churches and museums in France.
Another person of note was Pierre DUJON, a French writer and philosopher who lived from 1709 to 1783. He was born in Nantes and is best known for his book "Traité de la Sagesse," which explored themes of morality and virtue.
In the 19th century, the DUJON name appeared in the United States, likely brought by French immigrants. One example is Émile DUJON, who was born in France in 1823 and later became a prominent architect in New Orleans, Louisiana, where he designed several notable buildings.
Another historical figure was Marie DUJON, a French writer and activist who lived from 1848 to 1920. She was born in Paris and was involved in the women's suffrage movement, campaigning for the right of women to vote in France.
Finally, one of the more recent notable individuals with the DUJON surname was Marcel DUJON, a French artist and sculptor who lived from 1888 to 1976. He was born in Marseille and is known for his abstract and modernist sculptures, which can be found in various art galleries and public spaces across France.

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

Does the Census include every surname?
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.
