Origin
The surname Petit is of French origin, derived from the Old French word "petit" meaning "small" or "little." It is believed to have originated as a descriptive nickname referring to a person's physical stature or as a means of distinguishing between individuals with the same given name.
The earliest recorded instances of the surname Petit can be traced back to the 11th century in various regions of France, including Normandy, Brittany, and Île-de-France. It is found in medieval records such as the Domesday Book, a comprehensive survey of England and parts of Wales commissioned by William the Conqueror in 1086.
During the Middle Ages, the surname Petit was particularly prevalent in the regions of Normandy and Brittany. Historical records from this period mention notable individuals bearing this surname, including Geoffroy Petit, a knight who fought in the Battle of Bouvines in 1214, and Jeanne Petit, a French heroine who played a crucial role in the defense of Rouen during the Hundred Years' War.
As the surname spread across Europe, it underwent various spelling variations, such as Petyt, Pettit, and Pettitt, reflecting regional differences in pronunciation and scribal practices. In England, the name is often found as Pettit or Pettitt, while in Germany, it is sometimes spelled as Petit or Petith.
Several prominent figures throughout history have borne the surname Petit, including:
1. Jean Petit (c. 1360-1411), a French theologian and one of the leaders of the Burgundian faction during the Armagnac-Burgundian Civil War.
2. Pierre Petit (1594-1677), a French painter and engraver known for his religious works and portraits.
3. Alexis Petit (1799-1859), a French mathematician and engineer who made significant contributions to the development of differential equations.
4. François Petit (1828-1890), a French astronomer and pioneer in the field of astrophotography.
5. Charles Petit (1832-1897), a French sculptor known for his monumental works and sculptures for public spaces.
The surname Petit has also been associated with various place names, such as Petitville in Normandy, Petit-Couronne in Seine-Maritime, and Petit-Réderching in Moselle, France.
Demographics
Among Census respondents with the surname Petit, the largest self-reported group is White at 66.7%. The next largest groups are Black (21.0%) and Hispanic (8.2%).
The bar chart below shows how Petit 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 Petit 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.
