Origin
The surname Quiroga is of Spanish origin and can be traced back to the medieval era. It is believed to have originated from the Galician town of Quiroga, located in the northwestern region of Spain. The town's name is derived from the Latin word "quiricus," meaning "circle" or "ring," possibly referring to a circular shape or a settlement built around a ring-shaped defensive wall.
In the early Middle Ages, surnames were often derived from the names of places where people lived or were born. The earliest recorded instances of the surname Quiroga date back to the 13th century, when it appeared in various historical documents from the Kingdom of Galicia and the neighboring regions of northern Spain.
One of the earliest known bearers of the name was Pedro Quiroga, a nobleman and military leader who fought in the Reconquista, the campaign to reclaim the Iberian Peninsula from Moorish rule. He was born around 1220 and played a significant role in the capture of Seville in 1248.
During the 15th century, the surname Quiroga was associated with the noble family of the same name, who held significant landholdings and influence in the region of Galicia. Vasco Quiroga (1470-1565) was a prominent member of this family, known for his role as the first bishop of Michoacán in New Spain (now Mexico) and his efforts to protect the rights of indigenous peoples.
In the 16th century, another notable figure was Juan de Quiroga (1508-1565), a Spanish nobleman and military commander who served as the governor of New Spain (Mexico) from 1535 to 1537. He played a crucial role in the conquest and colonization of Central America and is remembered for his administrative reforms and efforts to establish order in the newly conquered territories.
Throughout the centuries, the Quiroga surname has been carried by several other notable individuals, including:
1. Antonio de Quiroga (1516-1594), a Spanish nobleman and military leader who served as the viceroy of New Spain from 1567 to 1576.
2. José Quiroga (1767-1784), a Spanish military officer and colonial administrator who served as the governor of Puerto Rico from 1781 to 1784.
3. Juan Rafael Quiroga (1790-1835), an Argentine military leader and politician who played a significant role in the Argentine War of Independence and served as the governor of Buenos Aires Province.
4. Vasco de Quiroga y Losada (1299-1367), a Spanish nobleman and military commander who participated in the reconquest of the Iberian Peninsula from the Moors.
5. Álvaro de Quiroga (1537-1594), a Spanish jurist and scholar who served as the president of the Council of the Indies, the highest governing body for the Spanish colonies in the Americas.
The surname Quiroga continues to be prevalent in Spain, particularly in the regions of Galicia and Asturias, as well as in various parts of Latin America, where it was introduced during the colonial era by Spanish settlers and conquistadors.
Demographics
Among Census respondents with the surname Quiroga, the largest self-reported group is Hispanic at 89.6%. The next largest groups are White (7.9%) and Asian/Pacific Islander (1.3%).
The bar chart below shows how Quiroga 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 Quiroga 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 Quiroga (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.
