Origin
Meaning and origin of Rabidou
The surname Rabidou has its origins tracing back to the Normandy region of northern France, where it emerged during the late medieval period around the 13th century. It is thought to be derived from the Old French words "rabide" meaning fierce or furious, and the suffix "ou" indicating a place or location. This suggests the name may have initially referenced a person residing in an area known for its intense or turbulent nature.
One of the earliest known records of the Rabidou name appears in a document from the year 1287, which mentions a landowner named Jehan Rabidou residing in the village of Montebourg, located in the former Normandy province. The name is also found in various legal contracts and property deeds from the 14th and 15th centuries, often spelled as Rabidoux or Rabidault, indicating slight variations in spelling over time.
During the 16th century, the Rabidou family spread across different regions of France, with notable members including Pierre Rabidou, a merchant born in Lyon in 1543, and Jacques Rabidou, a renowned physician from Paris who lived from 1568 to 1632. In the 17th century, the name appears in records from the city of Bordeaux, where a family of winemakers bearing the Rabidou surname was well-established.
As the centuries progressed, the Rabidou name continued to be found in various parts of France, with some individuals achieving notable status. One such figure was François Rabidou, a French military officer who fought in the Napoleonic Wars and was awarded the Légion d'Honneur in 1815 for his bravery on the battlefield. Another prominent individual was Émilie Rabidou, a celebrated French author and poet born in Marseille in 1824, whose works explored themes of love, nature, and the human condition.
Beyond France, the Rabidou name also found its way to other parts of Europe and the Americas through emigration. In the late 19th century, a family bearing the Rabidou surname settled in the town of Vilcabamba, located in the Loja province of Ecuador, where they became involved in agricultural pursuits. Additionally, records from the early 20th century indicate the presence of Rabidou families in Canada, particularly in the provinces of Quebec and Ontario.

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 Rabidou surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
