Origin
The surname DOIRON is of French origin, originating in the northern regions of France during the medieval period. It is believed to be a locational name derived from the French place name "d'Oiron," which refers to the town of Oiron located in the Poitou region of western France.
The name DOIRON likely emerged as a way to distinguish individuals from the town of Oiron, with the prefix "d'" indicating "from" or "of" the place. Early records show variations in spelling, including d'Oyron, d'Oiron, and Doiron, reflecting the evolution of the name over time.
One of the earliest known references to the name DOIRON can be found in the "Cartulaire de l'abbaye de Fontevraud," a cartulary (a medieval manuscript) from the 12th century, which mentions individuals with the surname d'Oiron associated with the Abbey of Fontevraud in Anjou, France.
Notable individuals with the surname DOIRON throughout history include:
1. Jacques Doiron (c. 1620-1687), a French Canadian pioneer and one of the first settlers in Acadia (present-day Nova Scotia and parts of New Brunswick).
2. Ambroise Doiron (1757-1835), a French Canadian farmer and landowner in Prince Edward Island, Canada.
3. Pierre Doiron (1891-1976), a French Canadian politician who served as a member of the Legislative Assembly of New Brunswick.
4. Gérard Doiron (1926-2007), a French Canadian artist and painter from New Brunswick, known for his landscape and portrait works.
5. Angèle Doiron (born 1963), a French Canadian actress and film director from New Brunswick, recognized for her contributions to the Acadian cultural renaissance.
The surname DOIRON has been present in various regions of France, Canada, and other parts of the world where French settlers and their descendants have established communities, reflecting the migration patterns and historical connections between these areas over the centuries.
Demographics
Among Census respondents with the surname Doiron, the largest self-reported group is White at 91.7%. The next largest groups are Two or More Races (3.1%) and Hispanic (2.9%).
The bar chart below shows how Doiron 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 Doiron 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.
