Origin
Meaning and origin of Joubert
The surname Joubert is of French origin and dates back to the Middle Ages. It is derived from the Old French personal name Joubert, which is a combination of the Germanic elements "gaud" meaning "bright" and "bert" meaning "famous" or "renowned".
The Joubert surname is believed to have originated in the region of Normandy in northern France, where it was first recorded in the 11th century. Over time, it spread to other parts of France and eventually to other countries as well.
One of the earliest historical references to the Joubert name can be found in the Domesday Book, a manuscript record of landholders in England commissioned by William the Conqueror in 1086. The name appears in various forms, including Joubert, Jaubert, and Gibert.
In the 12th century, a notable figure named Joubert de Chambre served as a knight and advisor to King Louis VII of France. Another prominent Joubert from this era was Gérard Joubert, a French prelate who served as the Bishop of Albi in the late 12th century.
During the 13th century, the Joubert name was associated with several prominent families in the regions of Normandy and Brittany. One such family, the Jouberts of Normandy, held the titles of Seigneurs de Bizy and Seigneurs de Mortemer.
In the 16th century, Jacques Joubert (1530-1593) was a notable French physician and writer who served as the personal doctor to King Henry III of France. His works on medicine and surgery were influential in their time.
Another notable figure was Daniel Joubert (1569-1638), a French Calvinist theologian and scholar who served as a professor at the University of Groningen in the Netherlands. He was known for his works on biblical exegesis and his involvement in the Synod of Dort.
In the 18th century, Barthélemy Catherine Joubert (1769-1799) was a French general who served under Napoleon Bonaparte during the French Revolutionary Wars. He played a significant role in several battles and campaigns before being killed in action at the Battle of Novi in 1799.
Petrus Joubert (1834-1900) was a prominent Afrikaner leader in South Africa during the late 19th century. He served as the Commandant-General of the South African Republic (Transvaal) and played a key role in the First Anglo-Boer War.

The bar chart below shows how Joubert 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 Joubert surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Joubert (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
