Origin
The surname Duplantis has its origins in France, where it first emerged in the late 16th century. It is believed to be derived from the French words "du" and "plantis," which together mean "from the plantation." This suggests that the name may have originally referred to someone who lived or worked on a plantation or farm.
In the earliest records, the name was often spelled as "Duplantis," "Duplantes," or "Duplantier." Some variations of the spelling include "Duplantiss," "Duplantisse," and "Duplantiz." These variations were likely due to regional dialects and the inconsistent spelling practices of the time.
One of the earliest documented references to the name Duplantis can be found in the parish records of Saint-Martin-de-Ré, a small island off the western coast of France. In the late 16th century, a family with the surname Duplantis was recorded as living in this area, which was known for its vineyards and salt marshes.
As the Duplantis family spread across France over the centuries, they left their mark in various regions. In the 17th century, there are records of a Duplantis family residing in the Bordeaux region, which was known for its wine production. Later, in the 18th century, the name appears in records from the Provence region in southeastern France.
Throughout history, there have been several notable individuals with the surname Duplantis. One of the earliest was Jean Duplantis (1620-1695), a French merchant and landowner who was influential in the development of the city of Bordeaux. Another prominent figure was Marie-Anne Duplantis (1755-1832), a French author and poet who was known for her romantic works.
In the 19th century, the Duplantis name gained recognition in the United States, where many French immigrants had settled. One of the most notable figures from this era was Jacques Duplantis (1825-1892), a successful businessman and landowner in Louisiana. He played a significant role in the development of the state's sugar industry.
Another prominent individual was Émile Duplantis (1870-1944), a French-American artist and sculptor who gained recognition for his works depicting scenes from Cajun life in Louisiana. His sculptures can be found in museums and public spaces throughout the state.
Finally, in the 20th century, Armand Duplantis (1911-1998) was a renowned French-American lawyer and civil rights activist. He was a vocal advocate for racial equality and played a crucial role in desegregating public spaces in Louisiana.
Demographics
Among Census respondents with the surname Duplantis, the largest self-reported group is White at 90.0%. The next largest groups are Hispanic (3.8%) and Two or More Races (2.2%).
The bar chart below shows how Duplantis 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 Duplantis 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.
