Origin
The surname GARDEA is of Spanish origin, tracing its roots back to the medieval era in the Iberian Peninsula. It is believed to have evolved from the Spanish word "guarda," which means "guard" or "watchman," suggesting that the name may have been associated with individuals employed as guards or sentries.
One of the earliest recorded instances of the GARDEA surname can be found in the historical archives of the Kingdom of Aragon, a medieval kingdom that encompassed parts of modern-day Spain and France. In the 13th century, a document mentions a certain "Pedro de Gardea" as a resident of the city of Zaragoza.
The GARDEA name also appears in several ancient manuscripts and chronicles from the region of Navarre, a former kingdom that now forms a part of northern Spain and southern France. One notable example is the "Crónica de los Reyes de Navarra," a chronicle of the kings of Navarre, which references a "Juan de Gardea" who served as a soldier in the royal army during the 15th century.
As the GARDEA surname spread across Spain, it underwent various spelling variations, including Gardea, Gardega, and Gardiga. These variations likely emerged due to regional dialects and differences in pronunciation.
Among the notable individuals bearing the GARDEA surname throughout history are:
1. Juan de Gardea (c. 1430 - 1492), a Spanish soldier and military commander who fought in the Reconquista, the prolonged campaign to expel the Moors from the Iberian Peninsula.
2. Martín de Gardea (c. 1520 - 1590), a Spanish explorer and conquistador who participated in the colonization of the Americas and the exploration of the Pacific Northwest region.
3. Isabel de Gardea (c. 1580 - 1650), a Spanish noblewoman and philanthropist known for her charitable works and support of religious institutions in Seville.
4. Francisco de Gardea (1635 - 1712), a Spanish architect and engineer who designed several notable buildings and infrastructure projects in Madrid and Andalusia.
5. Andrés de Gardea (1770 - 1848), a Spanish military officer and colonial administrator who served as the governor of Puerto Rico from 1820 to 1823.
The GARDEA surname has also been associated with various place names across Spain, such as Gardea de Abajo and Gardea de Arriba, which were small villages or hamlets located in the Basque Country region.
Demographics
Among Census respondents with the surname Gardea, the largest self-reported group is Hispanic at 92.0%. The next largest groups are White (6.0%) and Black (0.8%).
The bar chart below shows how Gardea 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 Gardea 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 Gardea (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.
