Origin
Meaning and origin of Deras
The surname DERAS has its origins in the Basque region of northern Spain and southwestern France, dating back to the early Middle Ages. It is believed to have derived from the Basque word "dera," meaning "valley" or "dale," suggesting that the original bearers of the name may have resided in or near a valley area.
One of the earliest recorded instances of this surname can be found in the Cartulario de San Millán de la Cogolla, a cartulary compiled in the 10th century, which contains references to individuals with the surname DERAS from the region of La Rioja in northern Spain.
In the 12th century, a nobleman named Sancho DERAS was mentioned in the Fuero de Logroño, a legal charter granted to the city of Logroño, which details his landholdings and privileges.
During the 13th century, the DERAS surname appeared in several manuscripts and records from the Kingdom of Navarre, indicating that the name had spread to other parts of the Basque region.
In the 15th century, a notable figure named Juan DERAS was a prominent merchant and landowner in the town of Vitoria-Gasteiz, which was then part of the Kingdom of Castile.
Another notable individual with the surname DERAS was Catalina DERAS, a Basque woman who lived in the 16th century and played a significant role in the defense of the town of Fuenterrabía during a siege by French forces in 1638.
Over time, the DERAS surname spread beyond the Basque region and can be found in various parts of Spain, as well as in some regions of France and Latin America, where Basque immigrants settled.
It is worth noting that variations of the spelling, such as DERRAS, DERRAZ, and DERASA, have also been recorded throughout history, reflecting local variations and adaptations of the name.

The bar chart below shows how Deras 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 Deras surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Deras (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
