Origin
The surname Lemieux originates from France, specifically the northern regions of the country. It is derived from the Old French word "l'amieus," which means "the friend" or "the beloved one." This name likely emerged during the Middle Ages, around the 12th or 13th century.
One of the earliest known records of the Lemieux surname appears in the Armorial Général, a collection of French heraldic arms compiled in the late 17th century under the reign of Louis XIV. This document lists several families bearing the Lemieux name, indicating their presence in various regions of France at that time.
The Lemieux surname has been associated with several notable individuals throughout history. One of the earliest recorded examples is Jean Lemieux, a French soldier who fought in the Hundred Years' War during the 15th century. Another prominent figure was François Lemieux, a French explorer and cartographer who accompanied Samuel de Champlain on his expeditions to North America in the early 17th century.
In the realm of literature, the name Lemieux appears in the works of French writer Honoré de Balzac, who featured characters with this surname in his novels "La Maison du Chat-qui-pelote" and "La Femme de Trente Ans." Additionally, Louis-Honoré Lemieux was a French painter active in the late 18th and early 19th centuries, known for his landscapes and portraits.
Across the Atlantic, the Lemieux surname gained a foothold in Canada, particularly in the province of Quebec, where many French settlers established themselves. One notable Canadian with this name was Sir Rodolphe Lemieux, a politician who served as a Member of Parliament and Speaker of the House of Commons in the early 20th century (1866-1937).
While the Lemieux surname is predominantly of French origin, it has also been adapted and adopted by families in other parts of the world, such as Belgium and Switzerland, where French-speaking communities have existed for centuries.
Demographics
Among Census respondents with the surname Lemieux, the largest self-reported group is White at 86.8%. The next largest groups are Two or More Races (4.2%) and Hispanic (3.1%).
The bar chart below shows how Lemieux 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 Lemieux 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.
