Origin
The surname Quant is of French origin and can be traced back to the 12th century in the regions of Normandy and Brittany. It is derived from the Old French word "quant," which means "how much" or "how many," suggesting that the name might have been a nickname for someone who frequently asked questions or was particularly inquisitive.
One of the earliest known records of the name Quant appears in the Rolls of Normandy, a collection of documents from the 12th and 13th centuries. In these rolls, a person named Robert Quant is mentioned as holding land in the village of Avranches in Normandy.
The Quant name can also be found in the Domesday Book, a comprehensive survey of land ownership in England commissioned by William the Conqueror in 1086. In this record, a person named Radulfus Quant is listed as a landowner in the county of Suffolk.
During the Middle Ages, the name Quant spread across various parts of Europe, including England, where it was often anglicized to "Quante" or "Quaunce." One notable bearer of this surname was Sir John Quant, a knight who fought in the Battle of Agincourt in 1415 during the Hundred Years' War between England and France.
In the 16th century, a notable figure with the surname Quant was Thomas Quant, a merchant and explorer who established trade routes between England and the Levant region (modern-day Turkey and the Middle East). He was born in Bristol, England, in 1525 and is believed to have died in Constantinople (present-day Istanbul) in 1578.
Another prominent individual with the Quant surname was Sir Henry Quant, an English politician and landowner who served as a Member of Parliament for the borough of Hythe in Kent during the late 16th and early 17th centuries. He was born in 1555 and died in 1623.
In the 18th century, a notable bearer of the Quant name was Jean-René Quant, a French philosopher and writer who was born in Dijon in 1717. He is best known for his work "Essai sur les mœurs et l'esprit des nations" (Essay on the Manners and Spirit of Nations), published in 1756.
Moving into the 19th century, one notable figure with the Quant surname was Sir William Quant, a British military officer who served in the Crimean War and the Indian Mutiny. He was born in 1824 and received numerous honors for his service, including the Order of the Bath and the Victoria Cross.
Demographics
Among Census respondents with the surname Quant, the largest self-reported group is Hispanic at 45.0%. The next largest groups are White (39.9%) and Asian/Pacific Islander (6.9%).
The bar chart below shows how Quant 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 Quant 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.
