Origin
The surname Poirier originates from France and dates back to the early Middle Ages. It is derived from the Old French word "poirier," which means "pear tree." This indicates that the name likely originated as a descriptive nickname for someone who lived near a pear tree or orchard, or perhaps someone who cultivated or sold pears.
One of the earliest recorded instances of the name Poirier can be found in the Domesday Book of 1086, where it appears as "Poherius" in the county of Gloucestershire, England. This suggests that individuals bearing this surname may have migrated from France to England during the Norman Conquest of 1066.
In France, the name Poirier has been particularly prevalent in the regions of Normandy, Brittany, and Poitou. It is believed that the name may have originated in one of these areas, where pear cultivation was common.
A notable figure with the surname Poirier was Germain Poirier (1724-1803), a French architect who designed several notable buildings in Paris, including the Théâtre Feydeau and the Église Saint-Philippe-du-Roule.
Another prominent individual was Pierre Poirier (1719-1786), a French theologian and philosopher who wrote extensively on theology and natural law.
In the realm of literature, Théodore Poirier (1846-1920) was a French poet and novelist known for his works that celebrated rural life in the Normandy region.
Jean-Claude Poirier (1938-2018) was a distinguished French anthropologist and ethnologist who conducted extensive research on the Inuit people of the Canadian Arctic.
Marie-Françoise Poirier (1935-2020) was a French artist and sculptor known for her abstract works in various media, including bronze, stone, and wood.
These examples demonstrate the historical prominence of the Poirier surname across various fields, ranging from architecture and theology to literature, anthropology, and the arts.
Demographics
Among Census respondents with the surname Poirier, the largest self-reported group is White at 92.0%. The next largest groups are Two or More Races (3.3%) and Hispanic (3.1%).
The bar chart below shows how Poirier 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 Poirier 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 Poirier (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.
