Origin
The surname LADET originated in France, first appearing in historical records during the early 13th century. It is believed to be a locational name derived from a place named Ladet, a small village in the Auvergne region of central France. The name may have evolved from an older spelling, such as Ladette or Ladect, reflecting the local dialect and pronunciation.
One of the earliest recorded instances of the LADET surname can be found in the Censier de Normandie, a medieval census document compiled in 1292. This record mentions a certain Guillaume LADET, a landholder from the village of Ladet.
In the 14th century, the LADET name appears in several municipal records from the city of Lyon, indicating that members of this family had migrated to the urban centers of France. A notable figure from this era was Jean LADET, a successful merchant and alderman who lived in Lyon between 1375 and 1432.
During the Renaissance period, the LADET family produced several notable figures in the arts and sciences. Pierre LADET (1510-1578) was a renowned painter and sculptor who worked in the court of King Francis I. His contemporary, Jacques LADET (1515-1592), was a respected physician and author of several treatises on medicinal plants.
In the 17th century, the LADET name gained prominence in the French military. Captain Louis LADET (1625-1698) was a celebrated cavalry officer who fought in the Wars of the Fronde and the Dutch War. His exploits were documented in several contemporary accounts, and he was awarded the prestigious Order of Saint Louis for his valor.
Another notable figure from this era was Marguerite LADET (1640-1721), a renowned poet and playwright whose works were popular in the salons of Paris. Her play "Les Amours de Psyché" was performed at the Comédie-Française and earned her the patronage of King Louis XIV.
As the LADET family continued to prosper and expand throughout France, the name appeared in various regions and villages. For example, in the 18th century, there were LADET families recorded in the regions of Burgundy, Poitou, and Brittany, suggesting that the name had spread across the country over the centuries.
Demographics
Among Census respondents with the surname Ladet, the largest self-reported group is Black at 53.7%. The next largest groups are White (43.5%) and Two or More Races (1.9%).
The bar chart below shows how Ladet 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 Ladet 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.
