Meaning and origin of Calvillo
The surname Calvillo has its origins in Spain, with the earliest recorded examples dating back to the 13th century. It is believed to be a locative surname, derived from the town of Calvillo in the province of Salamanca, Spain. The name is thought to come from the Latin word "calvus," meaning "bald" or "hairless," possibly referring to a geographic feature in the area.
One of the earliest known references to the Calvillo surname can be found in the Becerro de las Behetrías, a medieval Spanish manuscript from the 14th century, which lists names and properties in the region of Castile. This document includes mentions of individuals with the surname Calvillo, indicating its presence in the area during that time.
In the 16th century, a notable figure bearing the Calvillo surname was Juan Calvillo, a Spanish explorer and conquistador who participated in the conquest of Mexico alongside Hernán Cortés. He was born around 1490 in Extremadura, Spain, and played a crucial role in the Spanish conquest of the Aztec Empire.
Another significant individual with the Calvillo surname was Gaspar de Calvillo, a Spanish military officer and governor who lived in the 16th century. He served as the governor of the Spanish colony of Pánuco, located in present-day Mexico, from 1548 to 1552.
In the 17th century, Francisco Calvillo, a Spanish painter and engraver, made a name for himself with his religious works and portraits. He was born in Madrid in 1623 and is known for his paintings and engravings depicting religious scenes and portraits of notable figures of the time.
Moving forward to the 18th century, Diego Calvillo y Velarde, a Spanish military officer and engineer, left his mark on history. Born in 1691 in Seville, he served as the Chief Engineer of the Spanish Royal Navy and made significant contributions to the development of naval engineering and fortifications.
In the 19th century, José María Calvillo y Velarde, a Spanish politician and lawyer, played a prominent role in the political landscape of his time. He was born in 1789 in Seville and served as a member of the Spanish Cortes (parliament) during the reign of Queen Isabella II.

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.

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 Calvillo surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
