Origin
Meaning and origin of Aubin
The surname AUBIN is of French origin, deriving from the medieval French personal name Aubin, itself a variant of the Latin name Albinus, meaning "white" or "fair-haired." The name traces its roots back to the 5th century and the regions of Normandy and Brittany in northern France.
In medieval times, the name was sometimes spelled Aubyn or Aubain. It is believed to have originated from the Gallo-Roman personal name Albus, meaning "white" or "bright," which later evolved into the Germanic form Albinus during the era of the Merovingian dynasty in France.
One of the earliest recorded references to the name AUBIN can be found in the Domesday Book of 1086, where it is listed as a surname in the form "Albin" in various counties of England, likely brought over by Norman settlers after the conquest of 1066.
Notable historical figures bearing the surname AUBIN include Robert Aubin (c. 1156-1214), a French cleric and writer who served as the Archbishop of Rouen. Another early example is Jean Aubin (c. 1300-1368), a French lawyer and philosopher who served as the Chancellor of the University of Paris.
In the 15th century, Jean Aubin (c. 1420-1480) was a prominent French historian and chronicler who wrote extensively about the reigns of Charles VII and Louis XI. His works are considered important primary sources for understanding the politics and events of that period.
During the 17th century, Germain Aubin (1612-1695) was a French Dominican friar and historian who wrote several influential works on the history of the Catholic Church and the lives of saints.
In more recent history, one of the most notable individuals with the surname AUBIN was the French artist Gabriel Aubin (1865-1945), a Fauvist painter known for his vibrant landscapes and still life works.

The bar chart below shows how Aubin 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 Aubin surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Aubin (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
