The surname Plasencia is of Spanish origin, tracing its roots back to the medieval period in the regions of Extremadura and Castile. It is a toponymic surname, derived from the city of Plasencia, which lies in the province of Cáceres, Extremadura. The city's name is believed to have been derived from the Latin word "placentia," meaning "pleasing" or "pleasant," reflecting the area's natural beauty.
Plasencia was mentioned in the Codex Calixtinus, a 12th-century manuscript containing accounts of pilgrimages to Santiago de Compostela. This early record suggests the surname's presence in the region during that time. The name also appeared in the Libro de la Montería, a 14th-century manuscript documenting hunting expeditions of King Alfonso XI of Castile.
One of the earliest recorded instances of the surname Plasencia can be traced back to the 13th century. Rodrigo Plasencia, born in 1245, was a prominent scholar and theologian from Plasencia who taught at the University of Paris. Another notable figure was Álvaro de Plasencia, a 15th-century Spanish explorer and conquistador who accompanied Hernán Cortés on his expedition to Mexico.
In the 16th century, the surname gained prominence with figures like Antonio de Plasencia, a renowned architect who contributed to the construction of the Alcázar of Toledo, and Juan de Plasencia, a Catholic priest and missionary who played a significant role in the evangelization of the Philippines.
Moving into the 17th century, Gaspar de Plasencia y Zúñiga was a Spanish military officer and diplomat who served as the governor of the Duchy of Milan from 1668 to 1677. In the 18th century, José de Plasencia was a notable Spanish painter known for his religious and historical works.

Demographics
Among Census respondents with the surname Plasencia, the largest self-reported group is Hispanic at 93.7%. The next largest groups are White (5.2%) and Black (0.5%).
The bar chart below shows how Plasencia 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 Plasencia 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 Plasencia (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.
