Origin
The surname LLANOS is of Spanish origin, derived from the Spanish word "llano" meaning "plain" or "flatland." It is believed to have originated as a toponymic surname, referring to people who lived in or near a flat or level area of land.
The earliest recorded instances of the surname LLANOS can be traced back to the 13th century in Spain, where it was commonly found in regions such as Castile and Andalusia. In medieval times, the name was sometimes spelled as "Llano" or "Lanos."
One of the earliest known bearers of the LLANOS surname was Pedro de Llanos, a Spanish nobleman and military commander who fought in the Reconquista against the Moors in the 14th century. Another notable figure was Juan de Llanos, a 16th-century Spanish architect who contributed to the design and construction of several significant buildings in Seville.
During the Spanish colonization of the Americas, the LLANOS surname was carried across the Atlantic Ocean. In the 16th and 17th centuries, individuals with this surname played a role in the exploration and settlement of various regions in Latin America, particularly in areas known for their vast plains or "llanos."
Notable individuals with the LLANOS surname include:
1. Félix María de Llanos y Valdes (1768-1817), a Spanish military officer and revolutionary who fought against Spanish rule in Venezuela.
2. Manuel Antonio Llanos (1792-1862), a Venezuelan military leader and politician who served as President of Venezuela from 1843 to 1847.
3. Rudecindo Llanos (1888-1949), a Cuban baseball player who played in the Negro Leagues and was inducted into the Baseball Hall of Fame in 1963.
4. Joaquín Llanos (1906-1979), a Mexican sculptor and artist known for his monumental public works and abstract sculptures.
5. Consuelo Llanos (1925-2016), a Venezuelan painter and artist who gained recognition for her vibrant and colorful works depicting Venezuelan landscapes and culture.
While the LLANOS surname is most prevalent in Spain and Latin American countries, it has also been carried to other parts of the world through migration and diaspora communities.
Demographics
Among Census respondents with the surname Llanos, the largest self-reported group is Hispanic at 86.2%. The next largest groups are White (6.1%) and Asian/Pacific Islander (4.4%).
The bar chart below shows how Llanos 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 Llanos 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 Llanos (2000, 2010, 2020).
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.
