Origin
The surname Arangua originates from the Basque region, situated in the western Pyrenees that spans the modern-day territories of northern Spain and southern France. Its origins can be traced back to the early medieval period, around the 9th or 10th century.
Arangua is believed to be derived from the Basque words "aran" meaning valley, and "goi" or "goia" meaning high or elevated. This linguistic combination suggests that the name likely referred to individuals or families residing in high or elevated valleys within the Basque region.
Early references to variations of the name can be found in historical documents from the region, such as the Cartulario de San Millán de la Cogolla, a 10th-century collection of charters and documents from the Monastery of San Millán de la Cogolla in La Rioja, Spain.
One of the earliest recorded bearers of the name was Juan Arangua, a prominent landowner and nobleman from the town of Lesaka in Navarre, Spain, who lived in the late 15th century. Another notable figure was Martín de Arangua, a Basque soldier and adventurer who accompanied Hernán Cortés on his expeditions to Mexico in the early 16th century.
In the 17th century, Juan de Arangua y Lezama (1588-1662) was a Basque-Spanish jurist and legal scholar who served as a judge in the Royal Chancery of Valladolid, one of the highest courts in Spain at the time.
The name Arangua has also been associated with various place names in the Basque Country, such as the town of Aranguren in Navarre, which likely shares a similar etymological root.
Other notable bearers of the surname include Ignacio Arangua (1691-1754), a Spanish Jesuit missionary who worked in the Philippines, and José María Arangua (1831-1896), a Spanish politician and lawyer who served as a member of the Spanish Senate.
While the surname Arangua is relatively uncommon outside of the Basque region, it has been carried by individuals of Basque descent and has maintained a presence throughout Spain and parts of France over the centuries, reflecting the rich cultural and historical heritage of the Basque people.
Demographics
Among Census respondents with the surname Arangua, the largest self-reported group is Hispanic at 89.0%. The next largest groups are White (8.5%) and American Indian/Alaska Native (1.7%).
The bar chart below shows how Arangua 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 Arangua 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.
