Origin
The surname Pensis originated in France during the 13th century. It is believed to be derived from the Old French word "pense," which means "thought" or "contemplation." The name likely referred to a person who was known for their thoughtful or pensive nature.
One of the earliest recorded instances of the name Pensis can be found in the Cartulaire de l'abbaye de Saint-Père de Chartres, a medieval manuscript dating back to the 12th century. This document contains references to individuals with the surname Pensis living in the region around Chartres, a city in northern France.
In the 14th century, the name Pensis appeared in historical records from the Duchy of Burgundy, which was then a powerful feudal state in eastern France. The town of Poncey-sur-l'Ignon, located in the modern-day department of Côte-d'Or, was once known as "Poncey-Pensis," suggesting a connection between the surname and this locality.
One notable individual with the surname Pensis was Jean Pensis, a French scholar and theologian who lived in the 15th century. Pensis authored several works on religious subjects and was a member of the faculty at the University of Paris.
In the 16th century, a family bearing the name Pensis resided in the village of Sancerre, located in the Loire Valley region of central France. The Pensis family played a role in the local wine trade, which Sancerre is still renowned for today.
Another notable figure with the surname Pensis was Pierre Pensis, a French artist and engraver who was active in the early 17th century. Pensis is best known for his intricate engravings of architectural subjects and landscapes.
During the 18th century, the name Pensis appeared in records from the region of Normandy in northern France. One individual of note was Jacques Pensis, a merchant and trader who was born in Rouen in 1718 and traveled extensively throughout Europe and the Mediterranean.
While the surname Pensis has its roots in France, it has also been documented in other parts of Europe over the centuries, likely due to migration and the spread of French culture and influence.
Demographics
Among Census respondents with the surname Pensis, the largest self-reported group is White at 91.5%. The next largest groups are Black (2.5%) and Two or More Races (2.5%).
The bar chart below shows how Pensis 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 Pensis 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.
