Origin
The surname LLANAS has its origins in Spain, dating back to the medieval period. It is derived from the Spanish word "llana," which means "flat" or "level," referring to a geographical feature or a flat area of land.
One of the earliest recorded instances of the surname LLANAS can be found in the records of the city of Barcelona, where a family with this name resided in the 13th century. It is believed that this family may have owned or lived on a flat piece of land, which led to the adoption of the surname.
During the 15th century, the LLANAS surname appeared in various historical documents in the region of Catalonia, such as land records and tax rolls. This suggests that the name was well-established in this area during that time period.
In the 16th century, Juan LLANAS (1520-1589) was a notable Spanish poet and writer who hailed from the city of Valencia. His works, which included religious poetry and plays, were widely acclaimed during the Spanish Renaissance.
Another prominent individual with the LLANAS surname was Margarita LLANAS (1655-1721), a Spanish painter known for her religious artwork. She was born in Madrid and became a renowned artist, receiving commissions from churches and noble families throughout Spain.
Moving forward to the 18th century, José LLANAS (1745-1810) was a Spanish military officer who served in the Spanish Army during the Napoleonic Wars. He fought against the French forces and played a crucial role in several battles.
In the 19th century, Miguel LLANAS (1825-1892) was a Spanish architect renowned for his contributions to the revival of Catalan Modernism. He designed several notable buildings in Barcelona, including the Palau de la Música Catalana, which is now a UNESCO World Heritage Site.
During the 20th century, one notable figure with the LLANAS surname was María LLANAS (1920-1998), a Spanish writer and journalist. She wrote several novels and short stories that explored themes of social injustice and women's rights in Spain.
Demographics
Among Census respondents with the surname Llanas, the largest self-reported group is Hispanic at 93.0%. The next largest groups are White (6.1%) and Two or More Races (0.4%).
The bar chart below shows how Llanas 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 Llanas 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.
