Origin
The surname Bolduc originated in France, with records dating back to the 16th century. It is believed to have derived from the Old French word "bouleau," meaning "birch tree." This suggests that the name may have been initially associated with someone who lived near a birch forest or worked with birch wood.
One of the earliest recorded instances of the Bolduc name appears in the Parisian tax rolls of 1592, where a Jean Bolduc is listed as a merchant. Another early reference is found in the parish records of Saint-Malo, Brittany, where a marriage between Pierre Bolduc and Marguerite Leroy is documented in 1621.
In the 17th century, the Bolduc name spread across various regions of France, including Normandy, Picardy, and Burgundy. During this period, the name also appeared in various spellings, such as Boulduc, Bouduc, and Boulduc, reflecting the regional variations in pronunciation and orthography.
One notable individual with the Bolduc surname was Jacques Bolduc (1633-1716), a French painter and engraver who was born in Arles, Provence. His works were exhibited at the Académie Royale de Peinture et de Sculpture in Paris, and he is remembered for his portraits and religious paintings.
The Bolduc name also found its way to New France (modern-day Quebec, Canada) during the 17th and 18th centuries. One of the earliest recorded Bolducs in Canada was François Bolduc (1642-1707), who arrived in Quebec City in 1669 and later settled in Île d'Orléans, where he worked as a farmer.
Another notable figure was Louis Bolduc (1805-1866), a Canadian politician and lawyer from Quebec City. He served as a member of the Legislative Assembly of the Province of Canada and played a significant role in the debates surrounding the establishment of responsible government in Canada.
In the 19th century, the Bolduc surname was well-established in various parts of Canada, particularly in Quebec and Ontario. One prominent individual was Henri Bolduc (1863-1944), a Canadian lawyer and judge who served as a puisne judge of the Superior Court of Quebec.
Throughout history, the Bolduc surname has been carried by individuals from various walks of life, including artists, politicians, lawyers, and farmers. While its origins can be traced back to France, the name has left an indelible mark across multiple regions and countries.
Demographics
Among Census respondents with the surname Bolduc, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (3.8%) and Hispanic (2.2%).
The bar chart below shows how Bolduc 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 Bolduc 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.
