Origin
The surname Pettit originated in France and is derived from the Old French word "petit," meaning "small" or "little." It was initially used as a descriptive nickname for someone of small stature or a younger son in a family.
The name Pettit can be traced back to the 12th century in various regions of France, including Normandy, Picardy, and Île-de-France. It is believed that the name was introduced to England following the Norman Conquest in 1066, when many French settlers brought their surnames with them.
One of the earliest recorded instances of the name Pettit appears in the Domesday Book of 1086, which was a comprehensive survey of landowners and tenants in England commissioned by William the Conqueror. The name is listed as "Petitius" in this historical document.
In the 13th century, a notable bearer of the name was Jean Pettit, a French scholar and philosopher who taught at the University of Paris. Another early example is Robert Pettit, a merchant from Rouen, France, who was mentioned in records from the late 14th century.
During the Middle Ages, the surname Pettit was also associated with several place names in France, such as Petitville and Petitmont, which likely contributed to the spread and variations of the name.
In England, one of the earliest recorded individuals with the surname Pettit was John Pettit, born around 1450 in Oxfordshire. Another notable bearer was Sir William Pettit (1623-1707), an English lawyer and politician who served as Lord Chief Justice of Ireland.
Other historical figures with the surname Pettit include Thomas Pettit (1635-1718), an English Baptist minister and author; Jean Pettit (1608-1691), a French Jesuit missionary who worked in Canada; and Ambrose Pettit (1785-1859), an American politician and judge from Indiana.
Throughout history, the surname Pettit has been subject to various spellings, such as Petit, Petitt, Pettitt, and Pettitts, reflecting regional variations and linguistic changes over time.
Demographics
Among Census respondents with the surname Pettit, the largest self-reported group is White at 87.5%. The next largest groups are Two or More Races (4.0%) and Hispanic (3.6%).
The bar chart below shows how Pettit 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 Pettit 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.
