Origin
The surname LAFOUR is of French origin, dating back to the medieval period. It is believed to have originated in the region of Normandy, where it was likely derived from the Old French word "la four," meaning "the oven" or "the furnace." This suggests that the name may have been initially associated with a baker or someone who worked with ovens or furnaces.
In its earliest recorded form, the name appeared as "La Fourne" or "La Fournie" in various records from the 12th and 13th centuries in Normandy. Over time, the spelling evolved to its current form, LAFOUR. Some variations of the name found in historical records include La Fournée, La Fournie, and La Fournière.
One of the earliest known references to the name LAFOUR can be found in the Livre des Bourgeois de Rouen, a register of citizens in the city of Rouen, Normandy, from the 14th century. This document mentions a certain Jehan La Fournée, who was a resident of Rouen during that time.
In the 15th century, the name appears in the records of the Abbey of Fécamp in Normandy, where a monk named Pierre LAFOUR is mentioned. Another notable individual bearing this surname was Jacques LAFOUR, a merchant from Rouen who lived in the late 16th century.
During the 17th century, the LAFOUR name gained prominence in the region of Provence in southern France. One notable figure was Jean-Baptiste LAFOUR (1632-1708), a renowned painter and artist from Aix-en-Provence.
In the 18th century, the name was associated with several notable figures in the French military. For example, François-Marie LAFOUR (1736-1796) was a French general who served during the French Revolutionary Wars.
Another significant figure with the LAFOUR surname was Jean-Baptiste LAFOUR (1739-1820), a French architect and urban planner who was responsible for designing several notable buildings and urban projects in Paris and other cities in France.
As the name spread beyond France, it also found its way to other parts of Europe and eventually to the Americas. For instance, in the 19th century, there was a notable Canadian politician named Henri LAFOUR (1817-1897), who served as a member of the Canadian Parliament.
These are just a few examples of notable individuals with the surname LAFOUR throughout history, highlighting its French origins and its presence in various fields, including art, military, architecture, and politics.
Demographics
Among Census respondents with the surname Lafour, the largest self-reported group is White at 78.9%. The next largest groups are Hispanic (7.3%) and Two or More Races (5.5%).
The bar chart below shows how Lafour 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 Lafour 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.
