Origin
The surname Dupuis has its origins in France, dating back to the Middle Ages. It is a topographic name derived from the Old French words "du" meaning "of the" and "puis" meaning "well" or "spring." Therefore, the name Dupuis originally referred to someone who lived near a well or a spring.
In the 12th century, the name Dupuis was found in various regions of France, including Normandy, Brittany, and Île-de-France. It was also recorded in early French records, such as the Livre des Métiers, a list of professions from Paris in the 13th century.
One of the earliest recorded instances of the name Dupuis can be found in the Domesday Book, a medieval census commissioned by William the Conqueror in 1086. The name appears as "Dupuis" and "de Puis," indicating its Norman origin.
In the 14th century, a notable figure bearing the name Dupuis was Jean Dupuis, a French poet and author who lived from around 1305 to 1380. He is known for his works "Le Livre de l'Esperance" and "Le Livre de la Paix."
Another prominent individual with the surname Dupuis was Jacques Dupuis, a French Jesuit priest and theologian who lived from 1923 to 2004. He was known for his work in the field of religious pluralism and interreligious dialogue.
Other notable individuals with the surname Dupuis include:
1. René Dupuis (1621-1688), a French-Canadian explorer and fur trader who played a significant role in the early exploration of North America.
2. Marie Dupuis (1790-1868), a French actress and theater manager who was renowned for her roles in comedies and tragedies.
3. Pierre Dupuis (1610-1682), a French scholar and philosopher who studied ancient religions and mythology.
4. Jacques Dupuis (1637-1719), a French architect and engineer who designed several notable buildings in Paris, including the Church of St. Gervais and St. Protais.
The surname Dupuis has also been associated with various place names in France, such as Dupuis-et-Vaumorin, a commune in the department of Manche, and Dupuis-et-Pringay, a commune in the department of Aisne.
Demographics
Among Census respondents with the surname Dupuis, the largest self-reported group is White at 90.8%. The next largest groups are Two or More Races (3.7%) and Hispanic (2.5%).
The bar chart below shows how Dupuis 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 Dupuis 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 Dupuis (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.
