Origin
The surname Asencio has its origins in Spain, dating back to the 10th century. It is derived from the Spanish word "asensio," which means "wormwood," a type of herb. This indicates that the name may have been initially used as a nickname or a descriptive name for someone who grew, sold, or was associated with wormwood.
The earliest recorded instances of the surname Asencio can be found in medieval Spanish documents, particularly in the regions of Castile and Aragon. One of the earliest known individuals with this surname was Pedro Asencio, a landowner in the village of Villarrubia de Santiago, who lived in the late 12th century.
During the 13th century, the surname Asencio began to appear in various historical records, such as land deeds, tax records, and municipal documents. It is likely that the name spread across Spain as families migrated and settled in different regions.
In the 16th century, the Spanish conquest and colonization of the Americas led to the surname Asencio being introduced to the New World. One notable individual from this period was Juan Asencio, a Spanish explorer and conquistador who accompanied Hernán Cortés on his expedition to Mexico in 1519.
In the 17th century, the surname Asencio gained prominence in the artistic and literary circles of Spain. Diego Asencio, a renowned painter from Seville, was known for his religious works and portraits during the Spanish Golden Age. His artistic legacy has been preserved in various museums and art collections.
Moving into the 18th century, the surname Asencio became associated with political and military figures. José Asencio y Toledo, a Spanish military officer and statesman, played a crucial role in the Spanish colonial administration of Louisiana and Florida during the late 1700s.
Throughout the 19th and 20th centuries, individuals with the surname Asencio made significant contributions in various fields. Gregorio Asencio, a Spanish philosopher and educator born in 1818, was known for his influential writings on education and social reform. María Asencio, a prominent Spanish actress born in 1924, gained recognition for her performances on stage and in film.
As the surname Asencio spread across the globe, it has been associated with notable individuals in different countries. For example, Ramón Asencio, a Panamanian politician and diplomat born in 1930, served as the President of the United Nations General Assembly from 1985 to 1986.
While the surname Asencio has its roots in Spain, it has become a part of the cultural tapestry of many nations, reflecting the diverse histories and migrations of families over the centuries.
Demographics
Among Census respondents with the surname Asencio, the largest self-reported group is Hispanic at 90.8%. The next largest groups are White (5.9%) and Asian/Pacific Islander (1.1%).
The bar chart below shows how Asencio 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 Asencio 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 Asencio (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.
