Origin
The surname ARPA has its origins in the Basque region of Spain and France. It is derived from the Basque word "arpa," meaning "cliff" or "rock." This suggests that the name may have originated as a topographic surname, referring to someone who lived near a cliff or rocky area.
The earliest recorded instances of the name ARPA date back to the late medieval period in the Basque Country. One of the earliest known references is found in a document from the 14th century, where a person named Juan de Arpa is mentioned as a landowner in the town of Durango, located in the province of Biscay.
In the 15th century, there are records of several individuals with the surname ARPA in various parts of the Basque region. One notable example is Pedro de Arpa, a merchant from San Sebastián, who was involved in trade with other European cities during the 1460s.
Throughout the 16th and 17th centuries, the ARPA surname can be found in various historical records and documents from the Basque Country. One prominent figure was Domingo de Arpa, a priest and scholar who lived in the late 16th century and wrote several works on theology and philosophy.
In the 18th century, the ARPA surname spread beyond the Basque region, with some individuals migrating to other parts of Spain and even to Spanish colonies in the Americas. One such individual was Juan Bautista de Arpa, a soldier who served in the Spanish army during the Seven Years' War and later settled in Cuba.
Another notable figure from this period was Ignacio de Arpa, a Basque architect who worked on several projects in Madrid and other Spanish cities in the late 18th century. He was known for his innovative designs and contributions to the development of neoclassical architecture in Spain.
As the centuries progressed, the ARPA surname continued to be found across various parts of Spain and Spanish-speaking regions, although it remained particularly concentrated in the Basque Country. Some other historical figures with this surname include Miguel de Arpa, a successful businessman and landowner in the 19th century, and Juana de Arpa, a writer and poet who published several works in the early 20th century.
Demographics
Among Census respondents with the surname Arpa, the largest self-reported group is White at 56.2%. The next largest groups are Asian/Pacific Islander (35.5%) and Hispanic (5.8%).
The bar chart below shows how Arpa 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 Arpa surname at the time of the 2020 Census, not any inherent property of the name itself.

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 Arpa (2010, 2020).
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.
