Origin
The surname Blanc originated in France and is a French word meaning "white".

The name Blanc was initially given as a nickname or descriptive name to someone with fair hair or pale complexion.
The earliest known record of the surname Blanc dates back to the 12th century in Normandy, France. One of the earliest documented instances is found in a charter from 1195, which mentions a person named Willelmus Blanc, or William the White.
In the famous Domesday Book, a record of land ownership in England commissioned by William the Conqueror in 1086, there are several entries for people with the surname Blanc or similar spellings, such as Blancus or Blanchart.
During the Middle Ages, the surname Blanc was particularly prevalent in the regions of Normandy, Brittany, and Île-de-France in northern France. It was also found in other parts of the country, including Burgundy and Provence.
Notable individuals with the surname Blanc throughout history include:
1. Jean Blanc (c. 1380-1456), a French merchant and financier who served as the Mayor of Paris.
2. Claudine Blanc (1545-1608), a French midwife and author of one of the earliest works on midwifery.
3. Michel Blanc (1615-1684), a French painter known for his religious works and portraits.
4. Louis Blanc (1811-1882), a French politician, historian, and socialist philosopher who influenced the revolutionary movements of 1848.
5. Marcel Blanc (1892-1984), a French architect known for his Art Deco designs, including the Chapelle Notre-Dame-de-la-Route in Paris.

Demographics
Among Census respondents with the surname Blanc, the largest self-reported group is Black at 44.0%. The next largest groups are White (43.8%) and Hispanic (7.0%).
The bar chart below shows how Blanc 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 Blanc 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.
