Origin
The surname Arauz originated in Spain, where it first appeared in the 14th century. It is believed to be derived from the Arabic word "ar-rauz," which means "the garden" or "the orchard." This suggests that the name may have referred to someone who worked in or lived near a garden or orchard.
One of the earliest recorded instances of the Arauz surname can be found in the archives of the city of Valencia, where a certain Juan Arauz was mentioned in a document dated 1387. This provides evidence that the name was already in use in the late 14th century.
The name Arauz is also associated with the town of Arauz, located in the province of Navarre in northern Spain. It is possible that the surname originated from this place name, with early bearers of the name hailing from this region.
In the 15th century, the Arauz family gained prominence in the region of Andalusia, where they were involved in various trades and professions. One notable member of the family was Pedro Arauz, a merchant who lived in Seville in the late 1400s.
Another historical figure bearing the Arauz surname was Hernando Arauz, a Spanish conquistador who participated in the conquest of Peru in the 16th century. He served under the command of Francisco Pizarro and played a role in the subjugation of the Inca Empire.
During the 17th century, the Arauz family expanded their influence to the Spanish colonies in the Americas. One notable member was Juan Arauz, a government official who served as the governor of Panama from 1637 to 1641.
In the 18th century, the Arauz family continued to be a prominent presence in Spain and its colonies. One notable figure was Miguel Arauz, a writer and philosopher who lived in Madrid during the late 1700s.
As the Arauz surname spread across the Spanish-speaking world, it also took on various spellings and variations, such as Araus, Arauzo, and Araujo. These variations reflect the regional dialects and linguistic influences on the name over time.
In summary, the surname Arauz has a rich history spanning several centuries, with its origins rooted in Spain and possible Arabic influences. It has been associated with various historical figures and regions, and has evolved into several variations over time.
Demographics
Among Census respondents with the surname Arauz, the largest self-reported group is Hispanic at 92.4%. The next largest groups are White (5.8%) and Black (0.8%).
The bar chart below shows how Arauz 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 Arauz 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.
