Origin
The surname Picou is of French origin, tracing its roots back to the Normandy region of northern France during the medieval period. It is believed to be derived from the Old French word "pic," meaning "peak" or "pointed," possibly referring to a person who resided near a geographical feature such as a hill or mountain with a distinctive peak.
One of the earliest recorded instances of the name can be found in the Livre Pelut, a census of the residents of Normandy conducted in 1195. The document lists several individuals with variations of the surname, including Picoud, Picout, and Picou. This suggests that the name was already well-established in the region by the late 12th century.
During the Middle Ages, the Picou family appears to have been concentrated in the area around the town of Bayeux, located in the Calvados department of Normandy. Several historic records, such as the Cartulaire de Bayeux, a collection of charters and deeds from the 11th to 13th centuries, mention individuals bearing the Picou name who held positions of importance in the local community.
As the Picou surname spread beyond Normandy, it diversified into various spellings, including Picault, Picaud, and Picault-Picou. One notable figure was Guillaume Picault (c. 1440-1516), a French jurist and legal scholar who served as the President of the Parlement of Paris, one of the highest judicial positions in the Kingdom of France at the time.
In the 17th century, the Picou name gained prominence in the world of French literature with the birth of Philippe Picou (1642-1707), a poet and member of the Académie Française, the prestigious French scholarly institution. His works, which included odes, sonnets, and translations of classical texts, were widely celebrated during his lifetime.
Another figure of historical significance was Jean-Baptiste Picou (1762-1840), a French military officer who rose to the rank of General during the Napoleonic Wars. He distinguished himself in several crucial battles, including the Battle of Waterloo in 1815, where he commanded a division of the French army.
As the Picou family expanded across Europe and beyond, the name continued to leave its mark in various fields. For instance, Émile Picou (1855-1924) was a renowned French sculptor whose works adorned public spaces and monuments throughout Paris and other major cities in France.
These examples illustrate the rich history and legacy of the Picou surname, which has been carried by individuals who have made significant contributions to the arts, sciences, law, and military endeavors over the centuries.
Demographics
Among Census respondents with the surname Picou, the largest self-reported group is White at 72.4%. The next largest groups are Black (16.3%) and Hispanic (5.4%).
The bar chart below shows how Picou 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 Picou 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.
