Origin
The surname "MANCHA" is of Spanish origin, tracing its roots back to the medieval period in the Iberian Peninsula. It derives from the Spanish word "mancha," meaning "stain" or "blemish," potentially referring to a physical characteristic or location associated with the family's ancestry.
One of the earliest documented references to the surname can be found in the "Anales Toledanos," a medieval chronicle detailing the history of Toledo, Spain. The name appears in records dating back to the 13th century, indicating its long-standing presence in the region.
The name "MANCHA" is closely tied to the region of La Mancha, a vast plateau located in central Spain. Historical records suggest that the surname may have originated from individuals residing in or associated with this area, particularly during the time of the Reconquista, when Christian kingdoms were reclaiming territories from Moorish rule.
In the 16th century, the name gained literary prominence through Miguel de Cervantes' iconic novel, "Don Quixote de la Mancha." The protagonist, Don Quixote, and his faithful squire, Sancho Panza, hailed from the region of La Mancha, contributing to the surname's enduring association with Spanish culture and literature.
Notable individuals bearing the surname "MANCHA" include:
1. Rodrigo Mancha (born c. 1235), a prominent military leader during the Reconquista who served under Alfonso X of Castile.
2. María de la Mancha (c. 1490-1560), a Spanish noblewoman known for her patronage of the arts and her role in the construction of the Convent of Santa Clara in Cuenca.
3. Juan de la Mancha (c. 1530-1592), a Spanish conquistador who participated in the conquest of the Yucatán Peninsula and served as the first governor of Mérida.
4. Juana Mancha (c. 1610-1680), a renowned Spanish painter and one of the few female artists of her time to achieve recognition for her religious works.
5. Pedro Mancha y Cabrera (1770-1845), a Spanish military officer and politician who served as the Governor of Puerto Rico from 1823 to 1824.
While the surname "MANCHA" has its origins in Spain, it has since spread to other parts of the world through migration and cultural exchange, carrying with it a rich historical legacy deeply rooted in the Spanish language, literature, and medieval past.
Demographics
Among Census respondents with the surname Mancha, the largest self-reported group is Hispanic at 87.9%. The next largest groups are White (9.1%) and Asian/Pacific Islander (1.0%).
The bar chart below shows how Mancha 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 Mancha 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 Mancha (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.
