Origin
The surname Gallegos has its origins in Spain, specifically in the region of Galicia. It emerged during the medieval period, likely between the 8th and 12th centuries. The name is derived from the Latin word "Gallaeci," which referred to the Celtic tribes that inhabited the northwestern region of the Iberian Peninsula, known as Gallaecia in ancient times.
The earliest recorded instances of the surname Gallegos can be traced back to the 10th century, when it appeared in various historical documents from the Kingdom of Galicia. One notable example is the Codex Calixtinus, a 12th-century manuscript that mentions individuals with the surname Gallegos in connection with the pilgrimage to Santiago de Compostela.
As the name suggests, Gallegos originally referred to individuals hailing from the region of Galicia, which was then part of the Kingdom of León. The surname may have originated from a specific place name or location within Galicia, such as a town, village, or even a geographical feature.
Throughout history, several notable individuals have borne the surname Gallegos. One of the earliest recorded figures was Gonzalo Gallegos, a 13th-century Galician nobleman and military leader who played a significant role in the Reconquista against the Moors. Another prominent figure was Juan Gallegos, a 15th-century Spanish painter known for his religious works, including altarpieces and retablos.
In the 16th century, Fernán Gallegos, a Spanish sailor and explorer, accompanied Hernán Cortés on his expeditions to the Americas and participated in the conquest of Mexico. Around the same time, Rodrigo Gallegos served as a judge and magistrate in the Spanish colonial administration in Peru.
During the 17th century, Pedro Gallegos, a Franciscan friar, gained recognition for his missionary work among the indigenous populations of New Spain (present-day Mexico and the southwestern United States). He is credited with establishing several missions and converting numerous individuals to Christianity.
The surname Gallegos has been widely dispersed across various regions due to Spanish colonization and migration. While its roots can be traced back to Galicia, it has become a common surname in countries with significant Spanish heritage, such as Mexico, Argentina, and other parts of Latin America.
Demographics
Among Census respondents with the surname Gallegos, the largest self-reported group is Hispanic at 89.9%. The next largest groups are White (8.1%) and Asian/Pacific Islander (0.6%).
The bar chart below shows how Gallegos 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 Gallegos 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 Gallegos (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.
