Origin
Meaning and origin of Borunda
The surname Borunda has its origins in Spain, dating back to the medieval period. It is believed to be derived from the Spanish word "borrón," which means "blot" or "stain." This suggests that the name may have initially referred to someone with a distinctive physical characteristic or perhaps a stonemason who worked with mortar and plaster.
In the early 13th century, records show the name Borunda appearing in the region of Aragon, specifically in the town of Borau. It is possible that the name evolved from a place name or was influenced by the local Aragonese dialect.
One of the earliest documented references to the Borunda name can be found in the Libro de la Cadena, a medieval manuscript dating back to the 14th century. This historical document, which recorded important events and genealogies in the Kingdom of Aragon, mentions several individuals with the surname Borunda.
During the 15th century, the name Borunda gained prominence in the Basque region of northern Spain. Historical records from this period, such as the Fuero de Vizcaya, a legal code governing the Basque provinces, include references to notable Borunda families.
In the 16th century, a Basque explorer named Juan de Borunda (c. 1500-1570) played a significant role in the Spanish colonization of the Americas. He accompanied Hernán Cortés on his expeditions to Mexico and participated in the conquest of the Aztec Empire.
Another notable figure with the Borunda surname was Pedro de Borunda (1570-1640), a Spanish military officer and explorer who served as the governor of New Mexico in the early 17th century. He was instrumental in establishing Spanish settlements in the region.
In the 18th century, José de Borunda (1710-1785), a prominent architect from the Basque region, gained recognition for his contributions to the design and construction of several important buildings, including the Cathedral of Santiago de Compostela.
During the 19th century, the Borunda surname spread beyond Spain, with individuals bearing this name migrating to various parts of the Americas, including Mexico and the southwestern United States. One notable figure from this period was Mariano Borunda (1825-1890), a Mexican military leader who fought in the Mexican-American War and later served as the governor of the state of Chihuahua.
Throughout its history, the Borunda surname has been associated with various professions, including artisans, explorers, military leaders, and architects. While its origins can be traced back to medieval Spain, the name has since spread to various parts of the world, reflecting the migration patterns and cultural influences of those who carried it.
Demographics
Ancestry and ethnicity for Borunda

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 Borunda 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 Borunda (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.
