Origin
Meaning and origin of Lupin
The surname LUPIN has its origins in France, tracing back to the 12th century. It is derived from the French word 'lupin', which means 'a type of edible plant from the legume family'. This suggests that the name may have initially referred to someone who cultivated or traded in lupins.
One of the earliest recorded references to the name LUPIN can be found in the Chartres Cathedral cartulary from 1197, which mentions a certain Petrus Lupinus. It is believed that this was likely a Latinized version of the French surname LUPIN.
In the 13th century, the name appears in various medieval records across northern France, particularly in regions such as Normandy and Picardy. Variants of the spelling included Lupyn, Lupien, and Lupinus.
The surname LUPIN is also linked to several place names in France, such as Lupin-Sanvic, a commune in the Seine-Maritime department, and Lupin-Courtenaux, a locality in the Loiret department. These place names may have contributed to the widespread adoption of the surname in those areas.
Notable individuals with the surname LUPIN include:
1. Maurice Lupin (1810-1887), a French lawyer and politician who served as a deputy in the National Assembly.
2. Georges Lupin (1856-1927), a French artist known for his paintings of landscapes and portraits.
3. Edmond Lupin (1881-1964), a French engineer and industrialist who founded the Lupin Construction Company.
4. Renée Lupin (1904-1983), a French actress and singer who appeared in several films during the 1930s and 1940s.

Demographics
Ancestry and ethnicity for Lupin

The bar chart below shows how Lupin 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 Lupin 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 Lupin (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.
