Origin
The surname Pasillas is of Spanish origin, deriving from the Spanish word "pasilla," which refers to a type of small, dried chili pepper. This name likely originated in the regions of Spain where these chili peppers were cultivated or where individuals with connections to the chili pepper trade resided.
Historically, the surname Pasillas can be traced back to the late 15th century, during the height of the Spanish Inquisition. Records from this period indicate that a family bearing the name Pasillas resided in the city of Seville, which was a major trading hub for spices and agricultural products at the time.
One of the earliest documented references to the Pasillas surname can be found in the "Libro de Repartimiento de Sevilla," a manuscript detailing the distribution of land and property in Seville after the Christian conquest of the city in 1248. This document mentions a certain "Juan Pasillas," who was granted a parcel of land in recognition of his military service.
In the 16th century, the Pasillas surname gained prominence with the exploration and colonization of the Americas by Spanish conquistadors. Notable individuals from this period include Hernán Pasillas, a conquistador who accompanied Hernán Cortés on his expedition to conquer the Aztec Empire in present-day Mexico.
During the colonial era, the Pasillas surname spread throughout the Spanish territories in the Americas, particularly in regions where the cultivation of chili peppers and other spices was prevalent. One notable figure from this time was Francisca Pasillas, a landowner and businesswoman in the Spanish colony of New Mexico in the late 17th century.
As the Spanish Empire expanded, the Pasillas surname also found its way to other parts of the world, including the Philippines, where Spanish colonization took place in the 16th and 17th centuries. In 1786, a Spanish military officer named Juan Pasillas was appointed as the governor of the Philippines, serving in that capacity until 1788.
Throughout the 19th and early 20th centuries, individuals bearing the Pasillas surname continued to make their mark in various fields. Notably, Emilio Pasillas was a renowned Mexican painter and muralist who was active in the early 20th century, known for his vibrant depictions of Mexican culture and history.
Demographics
Among Census respondents with the surname Pasillas, the largest self-reported group is Hispanic at 94.8%. The next largest groups are White (3.8%) and American Indian/Alaska Native (0.6%).
The bar chart below shows how Pasillas 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 Pasillas 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.
