Origin
The surname Avalos has its origins in Spain, dating back to the medieval period. It is believed to be derived from the Spanish place name "Ávalos," which is a municipality located in the province of Toledo, Castilla-La Mancha region. The name itself is thought to have evolved from the Latin word "abalus," meaning "hazel tree" or "hazelnut."
One of the earliest recorded instances of the Avalos surname can be found in the 14th century. In 1349, a nobleman named Ruy López de Ávalos was mentioned in historical documents as the Lord of Avalos and a prominent figure in the court of King Alfonso XI of Castile. This suggests that the Avalos family held a significant position in Spanish nobility during that time.
The Avalos surname gained further prominence in the 15th century with the rise of the powerful Avalos family of Naples, Italy. This branch of the family originated from Spain but established themselves as influential nobles in the Kingdom of Naples. Notably, Innico d'Avalos, who lived from 1536 to 1600, was a renowned Spanish military commander and diplomat who served under Philip II of Spain.
In the 16th century, the Avalos name appeared in various historical records and manuscripts across Europe. One notable example is Fernando Francisco de Ávalos y Aquino, Marquis of Pescara, who was a Spanish nobleman and military leader born in 1489. He played a significant role in the Italian Wars and was celebrated for his military victories against the French.
Another prominent figure with the Avalos surname was Alfonso d'Avalos, Marquis del Vasto, born in 1502. He was a Spanish military commander and governor who served under Charles V, Holy Roman Emperor, and played a crucial role in the Italian Wars and the conquest of Tunis.
In the 17th century, the Avalos family continued to hold significant power and influence in Spain and Italy. Juan de Avalos y Mendoza, born in 1622, was a Spanish nobleman and military leader who served as the Viceroy of Sardinia from 1672 to 1675.
Throughout history, the Avalos surname has been associated with nobility, military prowess, and political influence, particularly in Spain and Italy. While the name's origins can be traced back to a small municipality in Spain, the Avalos family left a lasting impact on European history through their accomplishments and contributions.
Demographics
Among Census respondents with the surname Avalos, the largest self-reported group is Hispanic at 95.2%. The next largest groups are White (3.9%) and Asian/Pacific Islander (0.3%).
The bar chart below shows how Avalos 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 Avalos 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.
