Origin
Meaning and origin of Avellaneda
The surname Avellaneda originates from Spain, specifically from the town of Avellaneda located in the province of Cantabria. Its origins can be traced back to the 11th century, when it derived from the Castilian Spanish words "avellano" meaning hazelnut tree, and "eda" meaning place or location.
Historically, the name Avellaneda first appeared in medieval records and manuscripts from the region of Cantabria, where it was often associated with landowners or nobility who held properties near hazelnut groves. One of the earliest recorded instances of the name is found in the "Becerro de las Behetrías" (Book of Bequests), a 14th-century document that recorded land holdings and feudal rights in the region.
In the 15th century, a notable figure named Pedro Fernández de Avellaneda (c. 1455 - c. 1520) was a Spanish soldier and author who wrote a satirical parody of Miguel de Cervantes' famous novel "Don Quixote." This work, published anonymously, was titled "El Ingenioso Hidalgo Don Quixote de la Mancha" and caused a literary controversy during that time.
Another historical figure with the surname Avellaneda was Gertrudis Gómez de Avellaneda (1814 - 1873), a celebrated Cuban novelist and poet who is considered one of the most important writers of the 19th century Spanish Romantic movement. Her works, such as the novel "Sab" and the autobiographical "Autobiography and Letters," explored themes of abolition, feminism, and romanticism.
In the 16th century, the name Avellaneda was also associated with the town of Avellaneda, located in the province of Buenos Aires, Argentina. This town was named after Nicolás Avellaneda (1837 - 1885), who served as the President of Argentina from 1874 to 1880.
Other notable individuals with the surname Avellaneda include Juan Ramón Avellaneda (1888 - 1969), a Mexican physicist and mathematician known for his contributions to the field of quantum mechanics, and Andrés Avellaneda (1936 - 2018), a prominent Spanish film director and screenwriter who was known for his works in the genre of erotic cinema.

The bar chart below shows how Avellaneda 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 Avellaneda 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 Avellaneda (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.
