Origin
The surname Croix has its origins in France, where it first emerged during the medieval period. The name is derived from the French word "croix," meaning "cross." This connection to the Christian symbol suggests that the name may have originated among families who lived near a prominent cross or roadside crucifix.
One of the earliest recorded instances of the name Croix can be found in the 13th century Cartulary of Notre-Dame de Paris, which mentions a person named Radulphus de la Croix. This indicates that the name was already in use by the 1200s, likely as a descriptive reference to a location or landmark associated with a cross.
In the 14th century, the name appears in various documents, including the Rolls of Parliament and the Patent Rolls. For instance, a record from 1347 mentions a John de la Croix who was granted land in Buckinghamshire, England. This suggests that the name had spread beyond France by this time, possibly carried by Norman settlers after the conquest of England in 1066.
During the Renaissance period, the name Croix became more prominent, with several notable individuals bearing the surname. One of the most famous was Petrus de Cruce (Pierre de la Croix), a French philosopher and theologian who lived from 1290 to 1344. He was a renowned scholar at the University of Paris and wrote extensively on metaphysics and logic.
Another prominent figure was Jean de la Croix (John of the Cross), a Spanish mystic and Carmelite friar who lived from 1542 to 1591. He was a major figure in the Counter-Reformation and is revered as a Doctor of the Church for his influential writings on spirituality and mystical theology.
In the 17th century, the name Croix appeared in various forms, including de la Croix, de Cruce, and de Crucis. One notable bearer was Philippe de la Croix, a French composer and organist who lived from 1625 to 1695. He served as the organist at the Royal Chapel in Paris and composed numerous works for the organ and harpsichord.
During the 18th century, the name Croix was found in various parts of Europe, including France, Belgium, and Germany. One notable individual was François Pétis de la Croix, a French orientalist and translator who lived from 1653 to 1713. He was renowned for his translations of Persian and Arabic literature, including the famous collection of stories known as "The Thousand and One Nights."
As the centuries progressed, the name Croix continued to be associated with various prominent figures, including artists, scholars, and military leaders. While its roots can be traced back to medieval France, the surname has since spread globally, reflecting the diverse cultural and geographic influences that have shaped its history over the centuries.
Demographics
Among Census respondents with the surname Croix, the largest self-reported group is White at 80.7%. The next largest groups are Black (11.4%) and Two or More Races (4.4%).
The bar chart below shows how Croix 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 Croix 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.
