Origin
The surname Llosa is of Spanish origin, with its roots traced back to the medieval period in the Iberian Peninsula. It is believed to have originated as a toponymic surname, derived from a place name or a locality.
Llosa is thought to be a variant of the Spanish word "losa," which means a flat stone slab or a paving stone. This connection suggests that the name may have been initially associated with individuals who lived near or owned land with such stone slabs or paved areas.
Historical records indicate that the surname Llosa can be found in various regions of Spain, including Catalonia, Aragon, and Valencia. It is particularly prevalent in the province of Barcelona, where it has been documented since the 13th century.
One of the earliest recorded instances of the name Llosa can be found in the Llibre del Repartiment, a historical document from the 13th century that records the distribution of lands and properties in the Kingdom of Valencia after the Christian conquest. This document mentions individuals with the surname Llosa, indicating their presence in the region during that time.
Over the centuries, the surname Llosa has been associated with several notable figures. One such individual was Juan Llosa y Valdés (1498-1555), a Spanish military officer and governor who served in various colonial territories of the Spanish Empire, including Cuba and Florida.
Another prominent bearer of the name was Claudia Llosa, a Peruvian film director and screenwriter born in 1976. Her acclaimed works include the films "Madeinusa" (2006) and "The Milk of Sorrow" (2009), the latter of which won the Golden Bear at the Berlin International Film Festival.
In the literary realm, Mario Vargas Llosa (born 1936) is a renowned Peruvian novelist, essayist, and Nobel Laureate in Literature. Although his paternal surname is Vargas, his mother's maiden name was Llosa, contributing to his recognition and association with this surname.
Other notable individuals with the surname Llosa include Manuel Llosa y Puente (1852-1925), a Spanish politician and lawyer who served as the Minister of Public Instruction and Fine Arts, and José María Llosa (1912-1994), a Peruvian poet and literary critic.
While the surname Llosa may have evolved from various place names or localities over time, its origins can be traced back to the medieval period in Spain, where it gained prominence and spread to other regions through migration and cultural exchange.
Demographics
Among Census respondents with the surname Llosa, the largest self-reported group is Hispanic at 79.1%. The next largest groups are Asian/Pacific Islander (11.4%) and White (8.0%).
The bar chart below shows how Llosa 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 Llosa 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.
